AIR TRAFFIC CONTROL MANUAL OF OPERATIONS

FOREWORD

The idea behind this manual is to provide a basic and solid knowledge source to all the virtual air traffic controllers

within the IVAO network, especially those who want to prepare higher ratings exams. Therefore, the contents of

this Manual are applicable only to IVAO and ATC simulation.

This edition is based on ATC MANOPS from NAV CANADA and adapted. It is also a compilation of various real

publications coming from CAA, Eurocontrol, NAV CANADA, AENA, FAA and other agencies. All credits go to the

respective authors. Suggestions for improvements or comments concerning apparent errors or omissions should

be forwarded via e-mail to the Spanish Division training department.

B. you have verified that separation exists.127.4 Note 1: Aircraft that manoeuvre as a result of an ACAS/ TCAS or GPWS/TAWS RA and which may affect an ATC clearance will notify controllers when beginning the manoeuvre or as soon as workload permits. If an aircraft manoeuvers outside the limits of its clearance, the controller is not responsible for separation between it and other aircraft, airspace protected for other aircraft, terrain or obstructions.127.4 Note 2:When the ACAS/TCAS or GPWS/TAWS RA has been resolved the aircraft must advise ATC they are returning to their previously assigned clearance or subsequent amended clearance.127.4 Example:Edmonton Centre, Air Canada 345, ACAS/TCAS (or GPWS/TAWS) Climb.Moncton Centre, Canadian 920, clear of conflict returning to assigned clearance.

128 WAKE TURBULENCE

128.1Controllers are expected to be alert to the possible hazard to aircraft caused by wake turbulence, especially vortices.

128.1 Note: All aircraft produce vortices somewhat in proportion to their weight. Helicopters in forward flight produce vortices that, per pound of gross weight, are more intense than those of fixed-wing aircraft. However, since wake turbulence is invisible, its presence and exact location cannot be determined with precision.

128.2The effects of wake turbulence can be minimized through: A. the application of increased separation;B. the issuance of a cautionary; orC. the provision of wake-avoidance information.

128.2 Note 1: Studies of wake turbulence indicate that the vortex of heavier aircraft are of sufficient magnitude and persis- tence to require adjustments to rules, procedures, and separation minima normally used to provide a control service. Research into the phenomena of wake turbulence is continuing.

128.2 Note 2: Under specified conditions pilots may accept responsibility for their own wake turbulence separation.

128.3Determine an aircraft's wake turbulence category.

128.3 Note:FAA wake turbulence categories:A. small up to 41,000 pounds;B. large 41,001 to 255,000 pounds; andC. heavy more than 255,000 pounds.

ICAO wake turbulence categories:A. light – 7,000 kg (15,500 pounds) or less;B. medium – less than 136,000 kg (300,000 pounds) and more than 7,000 kg (15,500 pounds); andC. heavy – 136,000 kg (300,000 pounds) or more.

128.4You may apply a wake-turbulence minimum to any situation not covered by a specific minimum provided you have reason to believe there is a potential hazard due to wake turbulence.

ATC 24

128.5Issue a cautionary as required to:

128.5 Phraseology: CAUTION! POSSIBLE TURBULENCE FROM DEPARTING/ARRIVING (type of aircraft).

A. any category aircraft or hot air balloon operating behind a known heavy aircraft; orB. a light aircraft or hot air balloon operating behind a known medium aircraft.C. when consider necessary when 128.4 applies.

128.6Issue a cautionary concerning a departing aircraft to an arriving aircraft if: A. the aircraft use crossing runways where the projected flight paths will cross; andB. you are not providing radar service to the aircraft.

128.6 Diagram

128.7Issue a cautionary to an arriving aircraft if the preceding arriving aircraft is a heavier weight category if: A. the aircraft use:

1. the same runway;2. parallel runways less than 2,500 feet apart; or3. crossing runways where the projected flight paths will cross; and

B. you are not providing radar service to the aircraft.128.7 Diagram:

128.9Issue a cautionary to a departing aircraft concerning a preceding departing heavy aircraft if the projected flight paths will cross and: A. the following aircraft uses:

1. a crossing runway; or2. a parallel runway less than 2,500 feet away; and

B. the required 2 minutes separation will be reduced before the flight paths cross.

ATC 25

128.9 Diagram:

128.10Issue a cautionary to a taxiing aircraft, or to a vehicle, manoeuvring behind a heavy aircraft.

128.11Issue a cautionary to any aircraft if:A. you are in communication with the aircraft; andB. 1. you observe on radar that an aircraft will have less than the appropriate radar separation minimum from

a preceding aircraft; (N)128.11 B. 1. Note: This applies to an aircraft other than one to which you are providing radar control service.

2. you are aware that an aircraft in the departure phase of a low approach will follow a preceding aircraft by less than 2 minutes; or (N)

128.11 B. 2. Note: An aircraft in the departure phase of a stop-and-go or touch-and-go is treated as a takeoff.

3. you have reason to believe there is a potential hazard due to wake turbulence.

132.6Provide for the expeditious movement of aircraft departing on simulated urgent police matters or activefire-fighting missions.

132.6 Note: Unless the aircraft departing on these missions request emergency handling, do not interrupt the normal movement of itinerant airport traffic. Local aircraft however, may be redirected to accommodate these departures.

133 CLEARANCES, INSTRUCTIONS AND READBACKS

133.1An ATC clearance or instruction constitutes authority for an aircraft to proceed only in so far as known air traffic is concerned and is based solely on the need to safely expedite and separate air traffic.

133.1 Note: Pilots are required to comply with ATC clearances accepted by them and with ATC instructions directed to and acknowledged by them, subject to the pilot maintaining final responsibility for the aircraft's safety.

133.2Issue clearances and instructions with the least possible delay.

133.2 Note:At an airport where there is a Flight Service Station/ RCO and there is also an ATC PAL frequency, IFR departure clearances may be issued either through the FSS or directly to the aircraft using the PAL. Details for coordinating and using this procedure are to be contained in an arrangement between the IFR unit and the FSS including:A. procedures for informing the FSS of any ground delay;B. the departure instructions issued, for FSS traffic purposes; andC. mandatory frequency procedures to be used.

133.3Differentiate clearly between a clearance and an instruction by using the appropriate prefix.

133.3 Example:ACA252, CLEARED TO THREE THOUSAND.ACA252, CROSS MONCTON VORTAC AT THREE THOUSAND.

133.4Obtain an accurate “readback” if issuing or relaying an:A. IFR clearance or IFR instruction;B. amendment to an IFR clearance or IFR instruction; orC. instruction to an aircraft or vehicle to HOLD or HOLD SHORT of a runway or taxiway. (R)

133.5You may omit requesting a readback for an initial IFR clearance issued by a ground or clearance delivery controller provided:

A. no changes have been made to the originally filed flight plan;B. the clearance is issued by referring to a machine printed strip or a video display of the flight plan;C. the clearance includes a published standard instrument departure; (N)

133.5 C. Note: A published Departure Procedure is not a Standard Instrument Departure.D. no alternate instructions are included in the clearance; andE. there is no apparent misunderstanding of the clearance contents.

133.6Read back verbatim any IFR clearance or IFR instruction or amendments to IFR clearances or IFR instructions if: A. received from a controller; orB. requested by other agencies.

133.7If workload or traffic conditions prevent immediate provision of Class D service, instruct the pilot to remain outside the Class D airspace, until such time that conditions permit the services to be provided.

ATC 28

133.7 Note: Pilots are required to establish radio communication with ATC prior to entering Class D airspace. If a controller responds to a pilot's initial transmission with “(Aircraft identification) STANDBY”, radio communication is considered to have been established and the pilot may enter the airspace.

134 WEATHER INFORMATION

134.1Obtain weather information from aviation weather reports, supplemented by PIREPs and controllers' observations. When relaying Automated Weather Observation System (AWOS) reports, ensure pilots are made aware that the observations are reported by an automatic station.

201 APPLICATION

201.1Apply the rules and procedures contained in this part and Annex II in the composition and handling of ATC messages.

201.2You should fully understand each message before you begin a transmission.

201.3Identify the station called at all times.

201.4Identify the station calling and use the words “THIS IS” unless there is no likelihood of misunderstanding as to the source of the transmission.

201.4 Example:GOLF ALFA BRAVO CHARLIE THIS IS WINNIPEG TOWER.

201.5Ensure, as the originator of a message, that the “readback” is correct if it is necessary for the recipient to repeat a message verbatim.

201.6Identify and correct any errors in the “readback” or restate the clearance or instruction in full if there is any possibility of misunderstanding.

201.7Conduct transmissions in a normal conversational tone using standard phraseologies as prescribed in relevant documents or procedures.

201.8You should incorporate the highest possible intelligibility in each transmission by using the following speech transmitting techniques:A. enunciate each word clearly and distinctly;B. maintain an even rate of speech;

201.8 B. Note: If a message is to be copied, the rate of speech must be slow enough to allow the pilot to copy the transmission verbatim to avoid requests for repeats.

C. pause slightly before and after numbers; 201.8 C. Note: This technique makes numbers easier to copy.

D. maintain speaking volume at a constant level;E. be familiar with microphone operating techniques; andF. suspend speech temporarily if it becomes necessary to turn your head away from the microphone.

201.9Relay messages in plain language or approved phrases without altering the sense of the message in any way.

PART 3 — AIRPORT AND VFR CONTROL

300 GENERAL

301 PROVISION OF SERVICE

301.1The objective of airport and VFR control service is to maintain a safe, orderly, and expeditious flow of air traffic under the control of a Control Tower.

301.2Provide VFR control service to:A. airport traffic operating on the manoeuvring area;B. VFR aircraft operating within the control zone or Tower Radar Area; andC. IFR aircraft for which the tower has responsibility for control.

301.3Issue take-off or landing clearance to a fixedwing aircraft provided the operation takes place on:A. a runway; orB. another area that is approved and designated for that purpose.

301.4Provide information concerning known traffic and obstructions to fixed-wing aircraft landing on or taking off from a surface other than a runway or another area that is approved for thatpurpose.

301.4 Phraseology:LAND/TAKE OFF AT YOUR DISCRETION — and if necessary — TRAFFIC (description).301.4 Note: Except in an emergency situation, fixed-wing aircraft are not permitted to depart from or land on a taxiway.

302 RUNWAY SELECTION

302.1Assign the operationally suitable runway most nearly aligned into the wind if the wind speed is 5 knots or more.

302.2You may assign the “calm wind runway” provided:

302.2 Note: A “calm wind runway” is one that offers an operational advantage because of:A. length;B. better approach;C. shorter taxiing distance;D. noise abatement procedures;E. necessity to avoid flight over populated areas; orF. other reasons.

A. the wind speed is less than 5 knots; andB. you clearly indicate the wind direction and speed to the aircraft.

302.3You may suggest, or approve a request for, another runway provided:

A. you or the aircraft will gain an operational advantage; andB. you clearly indicate the wind direction and speed to the aircraft.

302.4At airports where runway configurations are appropriate, you may segregate light VFR aircraft from heavy VFR or IFR aircraft by using different runways, provided:

A. the surface wind components permit the use of more than one runway; andB. the pilot accepts the suggested runway.

ATC 61

302.5Consistent with safety of operations, when selecting preferential runways in accordance with an established Preferential Runway Program, consider the runway, visibility, and wind conditions as follows:

302.5 Note: 1 A Preferential Runway Program is an agreement established between the ATS provider, the airport operator, airport users, and other interested parties which directs the use of certain runways under certain conditions. The agreement may address such factors as noise abatement, capacity maximization, prevailing winds, airport layout, aircraft routing, etc.302.5 Note 2: The final decision on the acceptability of a particularrunway rests with the pilot.

A. runway conditions:1. for the purposes of selecting a runway in accordance with a Preferential Runway Selection Program, the runway may be considered as DRY or WET provided the Runway Surface Condition (RSC) report indicates that the runway is 75% or more BARE and DRY or BARE and WET, as applicable. 2. select the runway(s) most closely aligned into wind or the calm wind runway when the runway surface condition report indicates that surface contaminants cover more than 25% of:

a. the full preferential runway surface; orb. the cleared portion, if greater than 100 feet wide. 302.5 A. 2. b. Note: If a RSC indicates the runway as DAMP, use the procedures applicable to a DRY runway.

B. maximum crosswind component 25 kts, including gusts, for departures and arrivals provided:1. the runway is dry; and2. the visibility is equal to or greater than 1 statute mile / 1500m or RVR equal to or greater than 5,000 ft/1500m. 302.5 B. 2. Note: To assist in the application of sub-paragraph 302.5 B. concerning the selection of one or more runways, the angle between wind direction and runway and the wind speed, that fall within the limits of crosswind components are listed in the following table:

302.5 B. 2. Example:Wind is 020 degrees at 38 knots including gusts. The RSC report indicates both runways are bare and damp and the reported visibility is 3 statute miles. Runways 06R and 36 are available. Noise abatement, traffic volume or other reasons dictate a requirement for runway 06R. Referring to 302.5 B. Note runway 06R may be selected as the preferential runway since the wind speed of 38 knots is less than the maximum 39 knots permissible at a 40 degree angle, and the runway condition and visibility requirements are met.

C. maximum crosswind component 15 kts including gusts for departures and arrivals provided:1. the runway is wet; or2. the runway is dry and the ground visibility is less than 1 statute mile or RVR is less than 5,000 ft. 302.5 C. 2. Note: To assist in the application of sub-paragraph 302.5 C. concerning the selection of one or more runways, the angle between wind direction and runway, and the wind speeds that fall within the limits of crosswind components, are listed in the following table:

ATC 62

302.6Avoid operations on runways where a tailwind is present. On a dry runway only, for departures and arrivals, a 5 kt maximum tailwind or tailwind component (10kt in other cases), including gusts, is acceptable during the period required to move traffic to the more in-to-wind runway.

302.6 Note 1: The 5 kt tailwind component should be used as flexibility for ATC units in conducting runway change operations rather than for sustained operations.302.6 Note 2: Use judgement in balancing the need for expeditious decontamination of runways with the safety of in-to-wind operations.302.6 Note 3: To assist in the application of sub-paragraph 302.6 concerning the selection of one or more runways, the angle between wind direction and runway, and the wind speeds that fall within the limits of tailwind components, are listed in the following table:

303 TAXI INFORMATION

303.1Issue taxi authorizations and instructions in plain, concise language to aircraft taxiing on the manoeuvring area.

303.1 Phraseology:TURN NOW or TURN LEFT/RIGHT.CONTINUE or CONTINUE TAXIING.TAXI ON RUNWAY/TAXIWAY (number) CROSS RUNWAY (number).HOLD or HOLD SHORT OF RUNWAY/TAXIWAY (number) or HOLD ON RUNWAY/TAXIWAY (number) or HOLD (direction) OF RUNWAY/ TAXIWAY (number). TAXI TO POSITION (runway).

303.2Do not use the word “cleared” in conjunction with authorizations or instructions for aircraft totaxi or for equipment, vehicle or personnel operations.

ATC 63

303.3Do not use conditional clearances or instructions for the movement of airport traffic.

303.3 Note:Misinterpretation could be caused by a conditional clearance or instruction such as:A. taxi to position behind the landing aircraft; orB. proceed across runway one two after departing DC9.

303.4Include the specific route if alternate taxi paths are available.

303.5Instruct an aircraft or vehicle to either “cross” or “hold short” of any runway it will cross while on the manoeuvring area.

303.6If workload permits, provide information concerning known traffic and obstructions to aircraft taxiing outside of the manoeuvring area.

303.6 Phraseology:TAXI AT YOUR DISCRETION — and if necessary — TRAFFIC (description).303.6 Note:Movement of aircraft on the Apron is the responsibility of the pilot, the aircraft operator or the Airport Operator.

303.7If you consider it necessary, inform a taxiing aircraft that a portion of the manoeuvring area is not visible from the tower.

303.7 Phraseology:(Area) NOT VISIBLE, TAXI AT YOUR DISCRETION.303.7 Note: This is intended to cover situations where your view of the manoeuvring area is obstructed by a physical condition other than weather phenomena.

304 VHF DIRECTION FINDING SYSTEM (VDF)

304.1Do not use DF bearing information to separate aircraft.

304.2You may use DF bearing information to assist in visually locating an aircraft by correlating the DF bearing with the reported position of the aircraft.

304.3Request an aircraft to confirm its position if, in your judgment, the DF bearing and the reported position do not reasonably agree.

304.3 Phraseology:CONFIRM YOUR POSITION.304.3 Note 1:An inaccurate DF bearing indication may result when two or more aircraft transmit simultaneously.304.3 Note 2:Because of equipment tolerances and site location of the VDF antenna, allowances have to be made in determining the reliability of the position report.

304.4If an aircraft's position remains doubtful following a request for confirmation, inform the aircraft and use whatever other means are available to establish its position. (P)(N)

304.4 Phraseology:DF INFORMATION INDICATES YOUR BEARING TO BE (actual bearing).304.4 Note: Other means may include visual sighting, radar unit assistance, adjacent VDF assistance, and aircraft's heading.

305 AIRPORT EQUIPMENT

305.1 Keep fully informed of the operating status of airport equipment used by aircraft or ATC. (R)

ATC 64

305.2Display the operating status, if other than normal, so that it will immediately attract the attention of all concerned personnel.

306 TOWER CAB LIGHTING

306.1Keep lighting in the Control Tower cab to a minimum at all times. (N)

306.1 Note:Due to operational requirements of equipment (keyboards, strips), lighting levels must be adjusted to enable operation of the equipment and at the same time not interfere with visual acuity of the airport surroundings at night.

307 AIRPORT SURFACE DETECTION EQUIPMENT

307.1Augment visual observation of traffic operating on the manoeuvring area by referring to ASDE (Ivac ground radar):

307.1 Note:Visual scanning is considered the primary technique.

A. at night;B. when visibility, for any reason, is less than the most distant point of the manoeuvring area; orC. at any other time when, in your opinion, an operational advantage will be gained.

307.2You may use ASDE derived information to:

307.2 Note 1: Availability of ASDE information does not relieve the controller of the requirement to carry out all necessary coordination with other operating positions.307.2 Note 2: A verbal report from an identified aircraft or vehicle is not necessary if the ASDE indicates it has exited the area in question as instructed.307.2 Note 3: The ASDE-3 is designed to detect a target with a radar cross section of 3 square meters. This would include a vehicle as small as the smallest passenger car or truck.

A. determine that a runway or taxiway is clear of aircraft, vehicles or obstructions prior to a landing or a takeoff; B. confirm the location of aircraft and vehicles on the displayed airport manoeuvring area;C. provide directional instruction to pilots and vehicle operators on the displayed manoeuvring area when requested by them, or when deemed necessary by the controller;

307.2 C. Phraseology:TURN LEFT/RIGHT AT THE NEXT TAXIWAY/ RUNWAY.TURN LEFT/RIGHT ON TAXIWAY/RUNWAY (number) APPROXIMATELY (number) FEET AHEAD.307.2 C. Note:In order to be effective for this purpose the display must be closely and continuously monitored.

D. confirm compliance with control instructions to aircraft or vehicles operating on the displayed manoeuvring area; andE. provide directional instruction to crash, fire and rescue vehicles manoeuvring on any displayed area, as necessary.

307.3You may use ASDE provided you are satisfied that the presentation and performance are adequate for the function being performed.

307.4Identify a target observed on the ASDE display by correlating its position with one or more of the following:A. Pilot or vehicle operator position report.B. Controller's visual observation.C. An identified target return observed from another radar source.

ATC 65

307.5Do not provide directional guidance in the form of headings if using ASDE.

308 VISUAL SCANNING — MANOEUVRING AREA

308.1Airport and Ground controllers shall visually scan the manoeuvring area thoroughly before issuing clearances or instructions to airport traffic, and, to the extent possible, at other frequent intervals.

308.1 Note 1: At those locations where radar is available and there is no dedicated radar position, the airport controller's primary responsibility is to visually scan for airport traffic.308.1 Note 2: The following list of scanning techniques is included to assist in developing methods for scanning the manoeuvring area:

A. scanning has to be systematic;B. people can get “object hypnosis”, and only see things which move (scanning at least twice will help overcome this);C. the eyes should move from one point to another (not one continuous sweep);D. scanning should be from left to right, the same as you read; andE. the eye can only focus on an area that would be covered by the fist when your arm is extended in front of you.

308.2Ensure that the runway to be used by a departing or arriving aircraft is free, or will be free, of all known obstacles including vehicles, equipment and personnel before the departing aircraft commences its take-off roll or a landing aircraft crosses the runway threshold.

308.2 Note 1: In the case of an aircraft departing from an intersection, there is no need to advise of obstructions on the runway which are behind the intersection take-off point.308.2 Note 2: If the runway or a portion of the runway is not visible to the airport controller for any reason, including weather or a physical obstacle, it is expected you will ensure that vehicles, equipment and personnel you have been made aware of, are not on the runway.

TRAFFIC (type, location) LANDING RUNWAY TWO FIVE WILL HOLD SHORT OF RUNWAY THREE TWO, CLEARED TO LAND RUNWAY THREE TWO.For a departing aircraft:TRAFFIC (type, location) LANDING RUNWAY TWO FIVE WILL HOLD SHORT OF RUNWAY THREE TWO, CLEARED FOR TAKE-OFF RUNWAY THREE TWO.

D. you obtain an accurate readback when issuing a HOLD SHORT clearance to a landing aircraft; E. that, except for helicopters, the stopping distance group of the aircraft restricted to hold short is known and is in accordance with unit directives;

352.6 E. Note: Through a written agreement between the ATS unit and the aircraft operator, STOL aircraft may hold short in distances which are less than those shown in the stopping distance table.

F. the runway to be used by the restricted aircraft is bare; 352.6 F. Note: During winter operations, only the centre 100 feet (50 feet either side of the centreline) of the runway must be bare.

G. there is no standing water, slush, snow or ice (including frost), on the runways; 352.6 G. Note: These conditions may be reported by personnel qualified to perform runway surface condition inspections or by pilots. If a pilot who has just used the runway informs you that the runway is contaminated, you should request a runway surface condition report by authorized personnel.

H. for aircraft landing on any runway with a “hold short” restriction (LAHSO):1. there is no tailwind other than a calm wind; or

352.6 H. 1. Note: A tailwind is considered to exist whenever the surface wind exceeds an angle of 90o to the runway in use, thus adding to the ground speed of an aircraft using that particular runway.

2. there is no crosswind component exceeding 25 kts (including gusts). 352.6 H. 2. Note: To assist in the application of sub-paragraph 352.6 H. 2. concerning the selection of one or more runways, the angle between wind direction and runway, and the wind speeds that fall within the limits of crosswind components, are listed in the following table:

ATC 91

I. traffic information is issued to both aircraft;J. the conditions specified in D. and I. are met at the time, or before, landing clearance is issued and in sufficient time for the pilots to take other action if desired; and

352.6 J. Note: If a pilot prefers to use the full length of a runway or a different runway the pilot is expected to advise ATC in sufficient time to permit other arrangements.

K. if the restricted aircraft is a helicopter, the point of landing is separated, as measured perpendicularly, by at least 700 feet from the centreline of the other runway.

352.6 K. Note: Helicopters normally land without ground roll. When a pilot indicates, or a controller otherwise determines, that a landing will be accompanied by a ground roll, the actual point of landing must be adjusted, as necessary, to ensure that the helicopter will stop short of the other runway by the appropriate distance.352.6 K. Diagram:

352.7You may authorize simultaneous landings or a landing and a takeoff simultaneously on intersecting WET runways provided:

A. use of this procedure is approved in unit direction including the stopping distances for wet runways; B. the weather conditions are not less than a ceiling of 1,000 feet and visibility of 3 miles/5km;C. you do not conduct simultaneous operations if the braking action is reported less than good;D. there is no standing water, slush, snow or ice (including frost), on the runways;

352.7 D. Note: These conditions may be reported by personnel qualified to perform runway surface condition inspections or by pilots. If a pilot who has just used the runway informs you that the runway is contaminated, you should request a runway surface condition report by authorized personnel.

Note 2: To assist in the application of sub-paragraph 352.7 E. 2. concerning the selection of one or more runways, the angle between wind direction and runway, and the wind speeds that fall within the limits of crosswind components, are listed in the following table:

F. you do not instruct Group 6 aircraft to HOLD SHORT of an intersecting runway: andG. traffic information is issued to both aircraft.

352.8You may authorize simultaneous landings or a landing and a takeoff simultaneously on intersecting runways in tailwind conditions that are greater than four knots provided:

A. you suggest it and the aircraft accepts it; or352.8 A.Note 1: A request to an aircraft to land and hold short with a tailwind should be considered only for tactical purposes and not be advertised or planned as a routine procedure.352.8 A. Note 2: Clearly indicate the wind direction and speed to the aircraft at the time you suggest the landing AND with the landing clearance.

B. the aircraft requests a landing on a runway in which a “hold short” restriction will be issued; andC. the restricted aircraft's stop group category is compatible with the reduced runway length available to the pilot; andD. the tailwind speed does not exceed ten knots; andE. the runway that requires a “hold-short” restriction is dry.

352.9Hold a taxiing aircraft, until traffic using the runway has passed the point at which the aircraft is holding:

A. at a taxi holding position, if one has been established;B. at least 200 feet from the edge of the runway, unless other holding positions are established by markings or signs; orC. at a sufficient distance from the edge of the runway to ensure that no hazard is created to arriving or departing aircraft, if it is not practicable to comply with A. or B.

353 HELICOPTERS

353.1Issue take-off or landing clearance to a helicopter provided the operation takes place on the manoeuvring area.

353.1 Note 1: Because of their operational characteristics, it is not always necessary that helicopters adhere to the standard traffic circuit, land or take off on the same runway or follow the flight path used by fixed-wing aircraft. In IMC, however, helicopters conducting IFR flights are expected to climb out from or approach to an instrument runway. They may, of course, originate from or terminate at other locations on the airport via airborne or ground taxiing.353.1 Note 2: An area other than a runway or taxiway may be designated as manoeuvring area by the Airport Operator if it has been approved by the responsible Regional authorities.

ATC 93

353.2If a helicopter intends to take off or land outside the manoeuvring area:

353.2 Phraseology:(aircraft identification)(unit identification, if required) (special information, such as traffic, hazard or obstruction)(control instructions, such as departure routing or turn after takeoff)(wind information, if required) TAKE OFF AT YOUR DISCRETION (location)— or —(Control instructions)(traffic or other information) LAND AT YOUR DISCRETION.353.2 Example:GOLF JULIETT ALFA DELTA, TRAFFIC CHEROKEE DEPARTING RUNWAY 31, HOLD SHORT OF RUNWAY 31, WIND 300 AT 15 TAKE OFF AT YOUR DISCRETION FROM APRON 4.

A. provide instructions and traffic information, as necessary, for control purposes; andB. inform the aircraft that landing or takeoff will be at the pilot's discretion.

353.3 Include the specific route in a clearance to or from the landing area to ensure safe conformance with, or avoidance of other airport traffic, as necessary.

353.4Clear helicopters to air taxi unless:

353.4 Phraseology:CLEARED TO AIR TAXI or AIR TAXI, VIA (route), TO (location), (restrictions and special instructions as necessary), (traffic information, wake turbulence and other hazards), (wind information if required).353.4 Note 1: Due to the possible absence of visual cues to the pilot, caution is required when authorizing helicopter taxi operations at night or during daylight periods when ceiling or visibility is below VFR minima. It may be preferable in these circumstances for the helicopter to operate in the hover mode over lightedportions of the movement area.353.4 Note 2: Air taxi is the preferred method for helicopter movements on airports provided ground operations and conditions permit. Air taxi authorizes the pilot to proceed above the surface either via hover taxi or flight at speeds more than 20 knots. Unless otherwise requested or instructed, the pilot is expected to remain below 100 feet AGL. The pilot is solely responsible for selecting a safe airspeed and altitude for the operation being conducted.

A. the aircraft has specifically requested clearance to hover taxi or taxi on the surface; orB. the Regional Manager, Safety and Service Design has directed that helicopters are to taxi only via the hover mode in specified situations.

353.5Do not issue an air taxi or hover taxi clearance that will knowingly require a helicopter to pass over persons, vehicles, or aircraft.

353.6Include explicit route details in an air taxi or hover taxi clearance, if necessary, due to traffic or known ground hazards.

353.7At those locations where air taxi or hover taxi routes have been designated under the authority of the Regional Manager, Safety and Service Design clear helicopters along these routes in accordance with direction issued for their use.

353.8 Apply appropriate wake turbulence procedures to helicopters during air taxi or hover taxi as though they were departing aircraft.

353.9Avoid requiring frequency changes by helicopters known to be single-piloted while air taxiing, hovering or flying at low level.

354 PEDESTRIANS AND VEHICLES

354.1Keep ground traffic, such as pedestrians, vehicles, or construction equipment, away from taxiing aircraft.

ATC 94

354.2Hold ground traffic:A. at least 200 feet from the edge of an active runway, unless other holding positions are established by markings or signs; orB. at a sufficient distance from the edge of the runway to ensure that no hazard is created to arriving or departing aircraft, if it is not practicable to comply with A.

354.3Inform concerned aircraft of the circumstances if:

354.3 Note: This may be necessary during certain operations, such as construction, maintenance, or flight checks.

A. ground traffic is located less than 200 feet from the edge of the runway in use, unless other holding positions are established by markings or signs closer than 200 feet; andB. it is not practicable to close the runway.

354.4Take extra care at night and during periods of restricted visibility to ensure that:

A. the runway is clear for use when required; andB. information concerning the location of ground traffic is maintained by restricting vehicle movements to a particular runway, taxiway or other specific area on the airport.

354.5Do not use words and terms “go ahead”, “clear” or “cleared” in radiotelephony communications for ground vehicle operations.

354.6Respond to a radio call from a vehicle operator in the following form: A. (Vehicle identification).B. Unit function.C. STATE YOUR REQUEST or WHAT ARE YOUR INTENTIONS.

354.7Instruct a vehicle to either “cross” or “hold short” of any runway it will cross while on the manoeuvring area.

354.8Issue vehicle movement instructions as follows:A. (Vehicle identification).B. PROCEED VIA (route), (if applicable), CROSS RUNWAY (number) or PROCEED ONTO RUNWAY (number) TO (destination other than a runway), HOLD SHORT OF (runway, taxiway, other). (N)(R)

354.8 B. Note: Do not use the word “TO” in the route if a vehicle's destination is a runway.C. LEAVE, EXIT, GET OFF RUNWAY (number) AT (location) AND REPORT/ADVISE WHEN OFF THE RUNWAY.

354.9Precede a refusal or delay to a request, with the word “NEGATIVE” followed by further instructions and if necessary, the reason.

354.9 Phraseology:NEGATIVE HOLD YOUR POSITION (reason).— or —NEGATIVE HOLD SHORT OF RUNWAY (number) (reason).

354.10Use the direction contained in 316.3 to control aircraft and the movement of vehicles, equipment and personnel on the manoeuvring area when radio communications cannot be employed.

354.11If all other forms of communication fail, you may flash the runway lights on and off as a signal to vehicles and pedestrians to vacate the active runway.

ATC 113

420 CLEARANCE LIMITS AND ROUTES

421 CLEARANCE LIMITS

421.1At least 5 minutes before an aircraft reaches its clearance limit, issue:

421.1 Note 1: If a clearance is not received, the aircraft is expected to hold in a published holding pattern or if there is no published pattern, a standard pattern on the inbound track to the clearance limit and to request further clearance or an approach clearance. If communication cannot be established with ATC, the aircraft is then expected to proceed in accordance with communication failure rules and procedures.421.1 Note 2: An arriving aircraft, which has filed an RNAV STAR, is expected to fly this route, as cleared, to the terminal area entry fix (bedpost) or fix associated with the RNAV STAR. If no further clearance has been received upon reaching that point, the pilot is expected to fly the lateral route of the RNAV STAR for the instrument approach(es) serving the runway(s) in use, as specified on the ATIS, maintaining the last assigned altitude. In the event of a communication failure the pilot is expected to squawk 7600, fly the RNAV STAR as published, including the vertical and speed requirements as depicted in the procedure, intercept the final approach, fly inbound land as soon as possible.

A. a further clearance;B. an approach clearance; orC. a holding clearance.

421.1 C. Note: A late clearance may cause an aircraft to overshoot the holding fix.

421.2You should inform a high-performance aircraft if you anticipate that it may be required to hold en route or during descent.

421.2 Note: Aircraft require time to make any necessary adjustments needed to prepare for a restriction. For example, an aircraft could overshoot the holding area if it enters the holding pattern at a speed exceeding the applicable maximum holding speed.

430 ALTITUDE ASSIGNMENT

431 GENERAL

431.1Include one or more of the following items in an altitude instruction:

431.1 Phraseology:MAINTAIN (altitude) TO (reporting point)/UNTIL PAST (reporting point)/UNTIL (time).MAINTAIN AT LEAST 1,000 FEET ON TOP.CROSS (reporting point) AT (altitude)/AT OR ABOVE (altitude)/AT OR BELOW (altitude).CLIMB/DESCEND TO (altitude) IMMEDIATELY/ IMMEDIATELY AFTER PASSING (reporting point)/ AT (time).CLIMB/DESCEND TO REACH (altitude) AT (time)/ AT (reporting point).CLIMB TO (altitude) ON HEADING (number) BEFORE PROCEEDING ON COURSE.

A. The approved altitude ASL or flight level.B. The altitude at which to cross a reporting point if climbing or descending.C. The place or time at which to start climb or descent.

431.1 C. Note: Controllers should be aware that pilots who operate frequently in the United States may react differently to the expression “at pilot's discretion” when used in conjunction with an altitude assignment. In particular, the FAA Airman's Information Manual states: “The term 'at pilot's discretion' included in the altitude information of an ATC clearance means that ATC has offered the pilot the option to start climb or descent when the pilot wishes. The pilot is authorized to conduct the climb or descent at any desired rate, and to temporarily level off at any intermediate altitude. However, once the aircraft has vacated an altitude, it may not return to that altitude”.

D. The place or time at which an altitude is to be reached.E. The time or location to expect higher altitude when it is not practicable to initially assign an operationally suitable altitude or flight level.

431.1 E. Note: The following may be considered operationally suitable altitudes or flight levels:A. in the low level air structure, the flight-planned altitude or an altitude as near as possible to the flight planned altitude, taking into consideration the aircraft's route of flight; orB. in the high level air structure, an altitude no more than 4,000 feet below the flight planned altitude.However, if it is not practicable to assign the flight planned altitude and if the aircraft has not been informed when it may expect clearance to another altitude, it is the responsibility of the pilot to advise ATC if the assigned altitude will not permit the aircraft to proceed to the airport of destination if a communications failure should occur.

F. Detailed instructions for departure or approach.

431.2Clear an aircraft to maintain only one altitude beyond your area of responsibility unless otherwise coordinated with the concerned sector or unit.

431.2 Note: Normally, this is the altitude at which the aircraft will enter the adjacent area.

431.3Issue clearance to the altitude or flight level the aircraft was told to expect, prior to the time or location specified, if:

431.3 Note: The altitude to be expected, which was included in the clearance, is not applicableA. once the aircraft has proceeded beyond the fix; orB. the time designated if the clearance has expired.

A. it was not practicable to initially assign an operationally suitable altitude or flight level; or (N)431.3 A. Note: Where SIDs are not used, and interim altitude restrictions are required, the following is the proper application: An aircraft has filed FL370. FL190 is immediately available and FL370 will be available at 80 DME east of Prince George VORTAC. The clearance will read — “MAINTAIN FLIGHT LEVEL ONE NINE ZERO. EXPECT FLIGHT LEVEL THREE SEVEN ZERO, EIGHT ZERO DME EAST OF PRINCE GEORGE VORTAC”.

B. a SID was used. 431.3 B. Note: SIDs based on the criteria in Standards for the Development of Standard Instrument Departures and Standard Terminal Arrivals contain instructions informing the aircraft when to expect clearance to flight planned altitude or flight level.

431.4If an aircraft requests additional altitudes beyond your area of responsibility, instruct the aircraft to request the change en route.

431.4 Phraseology:REQUEST FURTHER ALTITUDE CHANGE EN ROUTE.

433.2 Note: MEAs are applicable to aircraft that have been cleared via airways/air routes. When aircraft operate below the MEA the required signal coverage may not exist requiring an increase in the lateral airspace to be protected.

A. in the interest of flight safety; 433.2 A. Note: Flight safety may be jeopardized by such conditions as icing or turbulence.

B. flight checking a NAVAID;C. on a medical evacuation flight; orD. if the navigation method used is GPS.

433.2 D. Note: Since GPS does not require ground-based NAVAID signal coverage to provide navigation accuracy additional protected airspace is not required.

433.3You may clear aircraft traversing airways/air routes below the MEA but not below the applicable minimum IFR alitude.

433.3 Note: Aircraft are considered to be “traversing an airway/ air route” when the airspace to be protected for the track of the aircraft infringes on the airspace to be protected for the airway/air route. An aircraft cleared “via direct” on a track that is coincident with an airway/air route is considered traversing the airway/ air route.

433.4Issue a revised clearance without waiting for a request from the aircraft if an aircraft has been cleared at an altitude that is below the minimum IFR altitude for a subsequent portion of the route.

433.5If it is necessary for an aircraft to make achange in altitude because of a higher MEA beyond the next fix, clear the aircraft to climb in sufficient time to enable it to cross the fix at or above the MEA established beyond the fix.

433.5 Diagram:

433.6If an altitude lower than the MEA for the leg being flown, but at or above the MEA established beyond the next fix, is requested, do not clear the aircraft to descend below the MEA for the leg being flown until after passing the fix beyond which the lower MEA is established.

433.6 Diagram:

434 SEPARATION BETWEEN FLIGHT LEVELS AND ALTITUDES ASL

434.1ATC 121

Do not assign any flight level that is lower than the lowest usable flight level determined by the transition level.

434.2Determine, from the following table, the lowest assignable flight level that will ensure at least the required vertical separation minimum between an aircraft flying on the standard pressure setting and:

A. an aircraft flying on an altimeter setting; orB. the upper limit of a Class F Restricted Airspace, if the upper limit is defined in terms of altitude ASL.

434.2 B. Note: Additional vertical separation is not required if the upper limit is defined in terms of flight level.

434.3Determine from the following table, the vertical separation required between an aircraft flying on an altimeter setting and the lower limit of a Class F Restricted airspace if the lower limit is defined in terms of flight level.

434.4Coordinate with adjacent sectors/units if a change in altimeter setting necessitates an increase, or permits a decrease, in: A. the lowest usable flight level; orB. the separation between flight levels and altitudes ASL.

435 ONE THOUSAND ON TOP

435.1You may clear an aircraft to maintain “at least 1,000 feet on top” provided: (N)(R)

435.1 Note 1: It is the aircraft's responsibility to ensure that the requested operation can be conducted above all cloud, haze, smoke, or other formation, with a flight visibility of 3 miles or more/5km or as prescribed according to the type of airspace. An aircraft's request can be considered as confirmation that conditions are adequate.435.1 Note 2: Some countries prohibit this procedure and for others it is not necessary to request it since it is uniquely pilot's responsibility.

A. the aircraft requests it; andB. the aircraft will operate within Class B airspace as previously cleared, Class C, D or E airspace. (P)

435.1 B. Phraseology:MAINTAIN 1,000 ON TOP WHILE IN CONTROLLED AIRSPACE NOT ABOVE (ALTITUDE RESTRICTION.

435.2ATC 122

You may clear an aircraft to maintain “at least 1,000 feet on top” without meeting the requirements of 435.1 provided this action is required to alleviate an emergency situation.

435.2 Note: In this case, you are expected to ask the aircraft to confirm that it can maintain a flight visibility of 3 miles/5km or more on top.

436 VFR CLIMB/DESCENT

436.1 You may clear an aircraft to change altitude in accordance with VFR provided:

436.1 Phraseology:CLIMB/DESCEND VFR FROM (altitude) TO (altitude).— and, if necessary —IF NOT POSSIBLE, (alternate instructions) AND ADVISE.

A. the aircraft requests it; and 436.1 A. Note: It is the aircraft's responsibility to ensure that the requested operation can be performed in visual meteorological conditions (VMC). An aircraft's request can be considered as confirmation that such conditions exist.B. the change will occur within Class B airspace, or within Class C, D or E airspace.

437 ALTITUDE REPORTS

437.1Ask an aircraft for verification of altitude if it does not provide this information on initial contact.

437.1 Phraseology:VERIFY YOUR ALTITUDE.437.1 Note: Pilots of IFR and CVFR flights are required to state altitude information on initial contact or when changing from one ATC frequency to another, unless otherwise instructed by ATS via ATIS or other methods.

437.2You may instruct an aircraft to report:A. reaching or leaving an altitude; or

437.2 A. Phraseology:REPORT REACHING/LEAVING (altitude).437.2 A. Note: Pilots of IFR and CVFR flights are required to report when leaving or reaching an assigned altitude, when being the descend at pilots' discrection.

B. passing an altitude during climb or descent.437.2 B. Phraseology:REPORT PASSING (altitude).

437.3It is a good practice to include the phraseology “Report Reaching” in all clearances for a climb or descent that will take place in whole or in part in RVSM airspace.

437.3 Phraseology:CLIMB/DESCEND TO (altitude) REPORT REACHING.

438 CONTROLLED VFR

438.1Include the contraction “VFR” in conjunction with the approved altitude in all clearances issued to a CVFR aircraft.

438.1 Example:MAINTAIN ONE FOUR THOUSAND VFR.

ATC 123

440 DEPARTURES

441 CLEARANCES

441.1If required for control, specify the following items in a departure clearance:

441.1 Example:DEPART RUNWAY ZERO SIX TURN LEFT HEADING ZERO FOUR ZERO UNTIL ABLE DIRECT NOT ABOVE FIVE THOUSAND UNTIL 20 DME.

A. Direction of takeoff and turn after takeoff. 441.1A. Phraseology:DEPART RUNWAY (number), TURN LEFT/RIGHT (if required).

B. Initial heading or track to be flown before proceeding on course. 441.1 B. Note 1: Aircraft issued a SID are expected to fly the headings or tracks specified on the SID chart until a radar vector is issued.441.1 B. Note 2: Aircraft instructed to fly “runway heading“ or a SID or departure procedure for which no specific heading is published, are expected to fly the heading that corresponds with the extended centreline of the departure runway until otherwise instructed. Drift correction will not be applied; e.g. Runway 04, magnetic heading of the centreline is 044 degrees, aircraft will fly heading 044 degrees.441.1 B. Note 3: If an airport and navigational aids of the same name are in close proximity to each other, detailed departure instructions may be required if there is doubt as to the pilot's intentions after departure. This is to prevent the pilot from proceeding to a NAVAID to establish a course of flight when a direct route is required for control purposes.

C. Altitude to be maintained before continuing climb to assigned altitude.D. Time or point at which an altitude or heading change is to be commenced or completed.E. Any other necessary manoeuvre.

441.2If you specify the time or point at which a departing aircraft is to start a turn, ensure that the clearance does not prevent the aircraft from clearing all obstacles and terrain.

441.3You may expedite a departure by suggesting a take-off direction other than into wind.

441.3 Note:It is the pilot's responsibility to decide among:A. making the takeoff;B. waiting for takeoff into wind; orC. requesting takeoff in another direction.

441.4You should make every effort to permit an aircraft that is departing on a long-range flight:

441.4 Note: Heavy take-off weights may make the early part of a flight critical.A. to proceed on course with as few turns as possible; andB. to climb to the assigned altitude with as few restrictions as possible.

441.5Clear a departing aircraft to the destination airport except in the following circumstances:A. You may clear an aircraft to a published radio fix serving the destination airport, provided the destination airport is within your control area or FIR. (N)

441.5 A. Note: Radio fixes used as clearance limits should be published in Letters of Agreement among FIRs. If there is no prevailing LoA, do not apply 441.5.

B. Clear an aircraft to a point other than the destination airport if:1. the destination airport is within another unit's control area or FIR; and2. the other unit requests you to do so.

441.6If you issue a clearance to a fix not serving the destination airport, you should inform the aircraft of any further restriction that is anticipated.

441.6 Note: This is necessary to permit the pilot to prepare for the restriction.

ATC 124

442 STANDARD INSTRUMENT DEPARTURES

442.1You may assign a SID and any necessary transition at those locations where a SID is published.

442.1 Phraseology:(SID name and number) DEPARTURE.— or —(SID name and number) DEPARTURE, (SID termination fix) (SID transition).442.1 Note: 441.1 B. Note 2 also applies here.

442.2If using a SID, include the following:

442.2 Example:CLEARED TO THE CALGARY AIRPORT, TORONTO ONE DEPARTURE,

A. name of SID;B. SID termination fix, if appropriate; C. if applicable, transition; andD. if necessary, time or location for the aircraft to expect climb to an operationally suitable altitude or flight level.

1. specify a clearance valid time; 443.1 A. 1. Phraseology:CLEARANCE VALID AT (time).

2. if a clearance valid time is deemed inappropriate, specify that a clearance validation is required; or 3. specify the event which must occur.

443.1 A. 3. Phraseology:CLEARANCE VALID WHEN (event).

B. the clearance is not issued through a control tower:1. specify in the clearance that the aircraft is not to depart until a specified time; or

443.1 B. 1. Phraseology:(IFR clearance) DO NOT DEPART UNTIL (time) (reason).

2. specify in the clearance that the aircraft is not to depart until a specified event has occurred; and 443.1 B. 2. Phraseology:(IFR clearance) DO NOT DEPART UNTIL (event) (reason).A. The proposed departure may not be on the same frequency as the conflicting aircraft.B. The proposed departure may not be able to positively distinguish the conflicting aircraft from other similar aircraft.C. A third party may not be aware of the need to relay information to a proposed departure unless that need is stated by the controller.

3. state the reason for the delay.

443.2If a departure time or event cannot be specified as in 443.1 B., do not issue a clearance until the clearance is valid.

443.3Issue a clearance cancelled time or specify that the clearance will be cancelled by an event if an aircraft must depart at or before a specified time or before the occurrence of an event.

ATC 125

443.3 Phraseology:CLEARANCE CANCELLED IF NOT AIRBORNE BY (time).CLEARANCE CANCELLED IF NOT AIRBORNE BEFORE (event).443.3 Note: For a clearance cancelled time, the effective time is the hour and minute stated in the clearance. Since seconds are not considered as part of the effective time, a clearance is cancelled when the stated time appears on the clock.

443.4Respond to a request for release of an IFR aircraft by stating the runway number.

443.4 Phraseology:(aircraft ident) VALID RUNWAY (number).

444 VFR RELEASE OF AN IFR AIRCRAFT

444.1You may approve an IFR aircraft's request to depart and maintain VFR until an IFR clearance is received provided you specify a time, altitude, or location at which the aircraft is to contact you for its IFR clearance.

444.1 Phraseology:CONTACT (unit) ON (frequency) AT (specific time, altitude, or location)/WHEN AIRBORNE, FOR IFR CLEARANCE.

444.2You may issue an IFR clearance for a departing aircraft to fly in accordance with VFR until a specified time, altitude, or location provided:

444.2 Phraseology:(IFR clearance), MAINTAIN VFR UNTIL (time)/TO (altitude or fix).— and if necessary —IF NOT POSSIBLE, (alternate instructions) AND ADVISE.

A. the aircraft requests it; and 444.2 A. Note: It is the aircraft's responsibility to ensure that the requested operation can be performed in visual meteorological conditions (VMC). An aircraft's request can be considered as confirmation that such conditions exist.

B. the restriction is only applied within Class B airspace, or within Class C, D or E airspace.

444.3If you are unable to approve a VFR departure, inform the aircraft of the reason for refusal.

444.3 Phraseology:UNABLE REQUEST (reason).

445 DELAYS

445.1Inform the operator of the time at which it is expected that an aircraft can be accommodated, if it will be necessary to delay the departure of an aircraft for a prolonged period of time.

ATC 126

450 HOLDING

451 HOLDING AREAS

451.1Determine holding areas in accordance with the directives contained in the ATC Holding Criteria Document. 451.1 Note:It has been determined that the airspace to be protected for aircraft holding using GPS matches the criteria in the ATC Holding Criteria Document.

452 HOLDING FIXES

452.1Do not use a DME fix located within the cone of ambiguity as a holding fix.

452.1 Note 1: When holding away from the NAVAID, the entire holding area must be clear of the cone of ambiguity.452.1 Note 2: When a TACAN facility has been specified as the clearance limit, special procedures are required because of the cone of ambiguity. Pilots have been advised that if no further clearance has been issued by the time the 10 DME is reached, the pilot is to commence a standard hold on the inbound radial between 10 DME and 15 DME and request further clearance. The 10 DME will be considered the holding fix. In addition, when a TACAN is being used as the primary navigation aid, and the clearance limit is a TACAN approach fix which is located on a radial other than the inbound radial of the aircraft, the aircraft is expected to hold, if required to do so, on the fix radial in a direction specified by the approach procedure.

452.2Do not hold aircraft flying a GPS procedure at the FAF. (N)

452.2 Note: Approach certified GPS receivers change to approach mode at 2 miles prior to the FAF. This provides significant changes to the course deviation indicator sensitivity, and RAIM, which can result in unpredictable results by the GPS receiver.

452.3If you use an intersection as a holding fix, ensure that:

452.3 Diagram:

A. the angle of the divergence of the bearings or radials is at least 45 degrees; andB. the ground based NAVAID providing the crossing radial or bearing is not more than:

1. 30 miles from the intersection if it is an NDB; or 452.3 B. 1. Note: This distance may be increased provided the minimum angle of divergence is increased by 1 degree for each mile in excess of 30 miles.

2. 45 miles from the intersection if it is not an NDB. (N)452.3 B. 2. Note: This distance may be increased provided the minimum angle of divergence is increased by 1/2 a degree for each mile in excess of 45 miles.

ATC 127

453 HOLDING PATTERNS

453.1If holding an aircraft at a fix for which there is no established holding area and which is not depicted on En route or IFR Terminal Charts, you should, as appropriate, take the following actions:A. Assign a standard holding pattern unless a non-standard holding pattern is required.

453.1 A. Note: A standard holding pattern involves right-hand turns with an adjustment to the outbound times to achieve 1 minute inbound legs up to and including 14,000 feet ASL and 1-1/2 minute inbound legs above 14,000 feet ASL.

B. Hold a military jet aircraft, other than a transport aircraft, on the side of the fix opposite that which will be used for the penetration procedure.C. Hold other aircraft on the side of the fix that will be used for the instrument approach procedure.

453.2You may approve an aircraft's request to deviate from a standard holding procedure provided you protect any necessary additional airspace.

453.3If a holding clearance is necessary at a fix for which a holding pattern is depicted, use the phraseology specified in 454.1 E. If the holding location required differs from that depicted use another appropriate phraseology as specified in 454.1.

453.3 Note 1: The most frequently used holding patterns are depicted on En route Low Altitude and En route High Altitude Charts and IFR Terminal Area Charts.453.3 Note 2: Pilots have been informed that upon reaching a clearance limit for which a holding pattern is depicted they are to hold in the location depicted unless cleared otherwise by ATC.

454 CLEARANCES

454.1If necessary, issue one of the following holding clearances:

A. Standard holding clearance. 454.1 A. Phraseology: CLEARED TO THE (fix), HOLD (direction) ON (specified) RADIAL/COURSE/INBOUND TRACK.

B. Non-standard holding clearance. 454.1 B. Phraseology: CLEARED TO THE (fix), HOLD (direction) ON (specified) RADIAL/COURSE/INBOUND TRACK, LEFT TURNS.

C. Detailed holding clearance. (P) 454.1 C. Phraseology: CLEARED TO THE (fix), HOLD ON (specified) RADIAL/COURSE/INBOUND TRACK, BETWEEN (location) AND A POINT (number) MINUTES (direction), RIGHT/LEFT TURNS. D. DME holding clearance. (P) 454.1 D. Phraseology: CLEARED TO THE (name) TACAN/VOR/NDB (specified) RADIAL/BEARING (number) DME FIX, HOLD BETWEEN (number) AND (number) DME. E. Published holding pattern clearance. (P) 454.1 E. Phraseology: CLEARED TO THE (fix), HOLD (direction) AS PUBLISHED.

454.2Issue, with the holding clearance, an expectapproach- clearance time, expect-furtherclearance time, or the time to depart the fix, and revise it as necessary.

454.2 Phraseology:EXPECT APPROACH CLEARANCE AT (time). EXPECT FURTHER CLEARANCE AT (time). DEPART (fix) AT (time).

454.3When clearing a GNSS equipped aircraft to an established DME hold, ensure the protected airspace of the GNSS equipped aircraft is completely contained within the established DME hold.

454.3 Note: DME holding fixes may be offset due to slant range.

ATC 128

455 SEQUENCING

455.1If it is necessary to establish a “stack,” you should: A. assign the lowest altitude to the first aircraft estimated to arrive over the holding fix; andB. assign succeeding aircraft successively higher altitudes.

455.2If a succeeding aircraft would be required to hold at an excessively high altitude, you should hold it at another fix until a lower altitude is available at the primary holding fix.

455.3If the weather is below the landing minima for an aircraft in an approach sequence and the aircraft informs you that it wants to hold and wait for an improvement in the weather, take one or more of the following actions:A. If necessary, remove the aircraft from its position in the approach sequence and either clear it to an adjacent fix or reclear it in the stack at an altitude which will permit other holding aircraft to do an approach.B. Ascertain the aircraft's intentions in the event of a communication failure occurring before receipt of an approach clearance.

455.3 B. Phraseology:ADVISE YOUR INTENTIONS IN EVENT OF COMMUNICATION FAILURE.

C. Issue appropriate communication failure instructions that cover the aircraft's stated intentions, if the intentions require other than normal communication failure procedures.

455.3 C. Phraseology:IF COMMUNICATION FAILS, PROCEED VIA (route) TO (airport) MAINTAIN (altitude) DEPART (fix) AT THE EXPECT-APPROACH-CLEARANCE TIME.

455.4If an aircraft is expected to be delayed 30 minutes or more at the destination airport:A. issue, either directly or through another unit, an expect-approach-clearance time; andB. inform the aircraft operator if practicable.

ATC 129

460 ARRIVALS

461 LANDING INFORMATION

461.1If DCPC is used, issue landing information before or shortly after the descent clearance.

461.2Include the following items, as appropriate, in landing information:

461.2 Example: AIR CANADA NINE ONE TWO CALGARY ARRIVAL, WEATHER AT 1700Z; WIND THREE TWO ZERO AT TEN, VISIBILITY THREE, LIGHT FREEZING RAIN; CEILING EIGHT HUNDRED OVERCAST; ALTIMETER TWO NINE FIVE FOUR; RUNWAY THREE FOUR, EXPECT ILS THREE FOUR; ICE PATCHES ON RUNWAY, DC9 REPORTED BRAKING ACTION FAIR AT ONE SIX FOUR FIVE.

461.3You may use the term “CAVOK” if applicable.

461.4Except during rapidly changing conditions, you need not issue information included in the current ATIS broadcast, provided the aircraft acknowledges receipt of the broadcast. (

461.5When issuing landing information, inform the aircraft if no altimeter, either local or remote, is available for that location.

461.5 Phraseology:ALTIMETER SETTING FOR (location) NOT AVAILABLE.

461.6Issue a remote altimeter setting when applicable.

461.7Issue to an aircraft any subsequent information, of which you have been made aware, that may affect its descent, approach, or landing.

462 EN ROUTE DESCENT

462.1If you clear a high-performance aircraft to descend and it is necessary to use a step-down procedure, you should issue further clearance well before the aircraft reaches the specified interim altitude.

462.2If an altitude report is necessary during a stepdown procedure, you should specify an altitude that is 2,000 feet or more from the altitude to which the aircraft has been cleared. (R)

463 CLEARANCE LIMIT

463.1Clear an arriving aircraft to a published fix from which an instrument approach can be carried out by specifying: A. the name of the fix; and

463.1 A. Note: It is expected you will assign the final approach course fix, or the initial or intermediate approach fix, for the anticipated approach in use as the clearance limit.

ATC 130

B. the route of flight.

463.2You may omit clearing an arriving aircraft to a published fix from which an instrument approach can be carried out, provided the aircraft has been cleared for a RNAV STAR.

464 APPROACH SEQUENCES

464.1Normally, clear IFR or CVFR aircraft for approach in the order in which they are estimated to arrive over the fix from which approaches are commenced.

464.2Do not clear a succeeding aircraft for an approach until the preceding aircraft: A. has cancelled or closed its IFR flight plan;B. is transferred to tower's control; C. has landed (except during instrument meteorological conditions at an airport served by a FSS, the preceding aircraft must be clear of the runway to be used by the succeeding aircraft); or

464.2 C. Note: The preceding aircraft may be considered clear of the runway if the aircraft has reported clear or the FSS has observed the aircraft to be clear.

D. is established on a missed approach procedure that provides the required IFR separation minima.

464.3During instrument meteorological conditions at an airport served by an FSS, if an arriving aircraft has landed but a clear of runway report has not been received, you may clear a succeding aircraft for an approach provided:A. you attempt to determine the location of the preceding aircraft; and

464.3 A. Note: You are expected to use such facilities as necessary to attempt to locate the position of the preceding aircraft. For example, request a visual scan of the airport area by the FSS or an airport official. B. you inform the succeeding aircraft that the preceding aircraft has landed but has not been reported clear of the runway.

465 APPROACH CLEARANCES

465.1Except as indicated in 465.8, specify in an approach clearance the published name of the approach as it appears in the AIP, and the route to be flown, if adherence to a particular procedure is required. Use the prefix “RNAV” in radio communications concerning RNAV(GPS) approaches.

465.1 Phraseology;CLEARED TO THE (name) AIRPORT (type) APPROACH.— or —CLEARED TO THE (name) AIRPORT RNAV RWY (number) APPROACH.— or —CLEARED TO THE (name) AIRPORT (type) APPROACH. PROCEED FROM (fix) TO (fix) VIA (route).465.1 Note 1:Unless a specific route has been issued with the approach clearance, the pilot may proceed via:A. the previously cleared route and transition to a fix; orB. any position along the route of flight directly to a fix; which will permit the aircraft to commence a published instrument approach.465.1 Note 2:Routing an aircraft via the Intermediate Waypoint (IWP), when on a GPS approach prevents the pilot from descending below the MSA until that fix. This may create a situation, where the pilot may be forced to descend at a greater than the recommended maximum permissible descent gradient as specified in TP 308. It is therefore recommended to route an aircraft via the IAWP if the difference between the initial and the intermediate segment altitudes is such, that a clearance via the IWP may cause the aircraft to be too high to complete the approach.465.1 Note 3: If visual reference to the ground is established before completion of a specified approach procedure, the aircraft is expected to continue with the entire procedure unless control is transferred to the tower and approved visual completion or the IFR flight plan is cancelled.

465.2If requested by an aircraft, or if an aircraft indicates that it is unfamiliar with the approach procedure, specify the following information as applicable:

ATC 131

465.2 Phraseology:INITIAL APPROACH AT (altitude). OUTBOUND (specified) RADIAL/COURSE/ TRACK. PROCEDURE TURN (direction) AT (altitude) WITHIN (distance) OF (NAVAID or FAF). FINAL APPROACH (specified) RADIAL/COURSE/TRACK. AUTHORIZED MINIMUM (altitude). IF APPROACH MISSED, (missed approach instructions).462.2 Note: Usually the aircraft indicates that it is unfamiliar with the approach since pilots do not have charts or are newbie. In that case, deal with it according to pilot abilities and ease the operation.

A. Initial approach altitude.B. Outbound track.C. Procedure turn direction and altitude.D. Distance within which procedure turn is to be completed.E. Final approach course.F. Authorized minimum altitude. (N) 465.2 F. Note: Authorized minimum altitude may be a decision height (DH) or a minimum descent altitude (MDA) as applicable.G. Missed approach procedure.

465.3Specify, in an approach clearance, any restrictions necessary to confine descent of an aircraft to a specific airspace, if:

465.3 Phraseology:CLEARED TO THE (name) AIRPORT (type) APPROACH. MAKE DESCENT (instructions).465.3 Note: If an aircraft, cleared without restriction to an airport, is approaching the fix or facility at an altitude higher than the procedure turn altitude, descent may be made in any sector to the sector altitude before commencing the established procedure.

A. the aircraft is approaching the fix or facility, from the initial approach or from within the holding pattern, at an altitude which is above the procedure turn altitude;B. it is necessary to confine the aircraft to a specific area for the provision of separation from other aircraft, including departures; andC. a shuttle pattern has not been published for the approach.

465.3 C. Note: Shuttle patterns are usually published where the initial approach altitude is more than 2,000 feet higher than the procedure turn altitude.

465.4Include, in an approach clearance, a clearance to circle to the runway in use, if the landing will be made on a runway other than that aligned with the instrument approach aid.

465.4 Phraseology:CLEARED TO THE (name) AIRPORT (type) APPROACH, CIRCLING PROCEDURE (direction if required) FOR RUNWAY (number). CLEARED TO THE (name) AIRPORT (type) APPROACH, CIRCLING PROCEDURE FOR ANY RUNWAY IS APPROVED.465.4 Note 1: If a missed approach is initiated during a circling procedure, the aircraft is expected to fly the published procedure as shown for the instrument approach just completed. The procedure for the runway on which the landing was planned will not be used.465.4 Note 2: Military aircraft may request to conduct an overhead break procedure utilizing VFR.

465.5Specify the direction of a circling procedure in relation to compass points.

465.5 Note: Do not use the terms “left” or “right”.465.5 Example:CIRCLING PROCEDURE NORTH/SOUTH FOR RUNWAY ZERO SEVEN.

465.6You may issue a clearance for a GPS overlay approach provided:A. the pilot requests it; andB. the aircraft is GPS equipped - suffix “G”.

465.6 B. Phraseology:CLEARED TO THE (name) AIRPORT – GPS OVERLAY (runway) APPROACH.465.6 B. Note 1: The protected airspace for an overlay approach is coincident with that of the underlying NAVAID approach.465.6 B. Note 2: Approval of the “GPS Overlay Approach” is independent of the serviceability of the underlying NAVAID.465.6 B. Example:CLEARED TO THE NORTH BAY AIRPORT GPS OVERLAY RWY 08 APPROACH.

465.7ATC 132

You should request which GPS overlay approach the pilot is planning if more than one is published for the approach runway.

465.8You may issue a non-specific approach clearance, traffic permitting.

465.8 Phraseology:CLEARED TO THE (name) AIRPORT FOR AN APPROACH.465.8 Note: If the type of approach is not specified, the pilot has the option of carrying out any approach. This does not include a contact approach or a visual approach (published or non-published). As soon as practicable after receipt of this type of clearance, the pilot should advise ATC or FSS of the type of approach procedure to be carried out, or request a visual or contact approach.465.8 Example: Following receipt of a non-specific approachclearance to the airport, the aircraft requests a visual or contact approach. If approving the visual or contact approach, since the aircraft has already been cleared to the airport, the controller need only advise the aircraft as follows:ROGER VISUAL/CONTACT APPROACH APPROVED.

465.9If weather conditions are close to the minima for the approach in use, you should plan for the possibility of a missed approach.

465.9 Note 1: A pilot will follow the published missed approach procedure for the instrument approach just completed if alternate missed approach instructions are not received.465.9 Note 2:Alternate missed approach instructions must not prevent the aircraft from clearing all obstacles and terrain.465.9 Example:Clearance not including specific missed approach instructions —IN THE EVENT OF MISSED APPROACH CLEARED TO THE YELLOWKNIFE VOR VIA VICTOR TWO ONE. MAINTAIN EIGHT THOUSAND.-or-Clearance containing alternate missed approach instructions — IN THE EVENT OF MISSED APPROACH CLIMB TO SIX THOUSAND ON THE FORT ST. JOHN VOR ZERO EIGHT NINE DEGREE RADIAL BEFORE PROCEEDING ON COURSE.

466 CONTACT APPROACH

466.1You may clear an aircraft for a contact approach provided:

466.1 Phraseology:CLEARED TO THE (name) AIRPORT, CONTACT APPROACH.CLEARED TO THE (name) AIRPORT, CONTACT APPROACH (runway).466.1 Note: Contact approaches may offer an operational advantage under marginal weather conditions when an aircraft indicates it is able to complete its approach by visual reference to the ground.

A. the aircraft requests it;466.1 A. Note: It is the aircraft's responsibility to ensure that the requested operation can be conducted clear of cloud with at least 1 nautical mile flight visibility with a reasonable expectation of continuing to the destination in those conditions. An aircraft's request can be considered as confirmation that such conditions exist.

B. there is an approved functioning instrument approach, or published GPS/GPS overlay approach for the airport; and

466.1 B. Note: If the only published instrument approach to the destination airport is a GPS approach, and the aircraft requests a contact approach, the request indicates that the aircraft is aware of the lack of ground based navaid approaches and able to fly the GPS approach.

C. you inform the aircraft when:1. the destination airport has published GPS/ GPS overlay approach(es) as well as a ground based NAVAID approach(es); and2. a suitable ground based NAVAID approach is unavailable or unserviceable.

466.1 C. 2. Note: An approach may be unavailable due to a weather phenomenon, activated class F airspace, or other factors.

466.2Issue alternate or missed approach instructions if weather conditions are such that completion of a contact approach is in doubt.

470 SEPARATION

471 APPLICATION

471.1Apply lateral, longitudinal or vertical separation between aircraft operating in accordance with an IFR or CVFR clearance, through consistent reference to and use of, the following three elements that are fundamental to safe, orderly and expeditious control:

471.1 Note 1: Separation is applied regardless of weather conditions.471.1 Note 2: The primary responsibility of controllers is to safely separate aircraft.471.1 Note 3: Although controllers must -ensure that aircraft are separated by not less than the appropriate minimum, in order to ensure an expeditious flow of traffic, you are expected to operate as closely to the prescribed minimum as circumstances permit.

A. Planning — determine the appropriate separation minimum required.B. Executing — implement the selected standard.C. Monitoring — ensure that the planned and executed separation is maintained.

471.2You need not apply separation provided:

A. an aircraft has been authorized to maintain “at least 1,000 feet on top”, except: (R)1. at night, apply separation between an aircraft maintaining “at least 1,000 feet on top” and other aircraft if any of the aircraft are holding; and2. between an aircraft maintaining “at least 1,000 feet on top”, and an aircraft operating on an ALTRV APVL;

B. a VFR restriction has been applied to an aircraft climbing or descending en route or to a departing aircraft; or C. control of an arriving aircraft has been transferred to the tower.

471.3Apply greater separation than the specified minimum if exceptional circumstances call for this extra precaution.

471.4If the type of separation or the minimum used to separate aircraft cannot be maintained, take action to ensure that another type of separation exists, or another minimum is established, before the previously used separation would be insufficient.

471.4 Note:For example, if two aircraft are on converging tracks, ensure that vertical or longitudinal separation exists before the second aircraft passes the point on its route at which the appropriate lateral separation would be infringed.

471.5Predicate control on ATC estimates based on aircraft performance as verified by position reports over fixes, determined by radio aids, radar, RNAV, or visual means that accurately define the position of the aircraft.

471.6Use aircraft estimates to verify ATC estimates. If a discrepancy exists between an aircraft's and an ATC estimate for the same reporting point, and separation could be affected:

471.6 Note: The requirement to use pilot estimates as a crosscheck of ATC estimates will vary depending upon the traffic density, the type of operations: arrival/ departure, enroute, radar, and if there is a known and valid wind component. In situations where there is limited opportunity to obtain position reports, ATC should obtain pilot estimates for a cross check (eg. an IFR flight, where the arrival fix is the only position after departure).

A. check the accuracy of the ATC estimate;B. if a discrepancy remains, request the pilot to check the aircraft estimate; andC. if following this action a discrepancy still exists, take appropriate action to ensure separation will not be compromised.

471.7Do not base separation on the assumption that the estimated time is correct if a position report is not received within a reasonable length of time after the estimated time over a reporting point. Take action to obtain the position report:A. as soon as practicable; orB. not later than 5 minutes after the estimated time over the reporting point, if flight safety is likely to be affected.

ATC 135

472 VERTICAL SEPARATION

472.1Apply vertical separation by assigning different altitudes.

472.2Separate aircraft vertically by using one of the following minimaA. FL290 and below - 1,000 feet.B. Above FL290 - 2,000 feet.

472.2 B. Note: Vertical separation of 1,000 feet may be applied in RVSM airspace and RVSM Transition airspace in accordance with 763.1.

472.3You may assign an altitude to an aircraft, only after an aircraft previously at the altitude, or an aircraft climbing or descending through the altitude, has reported or is observed:

472.3 Note: The climb or descent rate of both aircraft must be considered in determining when an aircraft may be cleared to the altitude that has been vacated.

A. leaving or passing the altitude; orB. leaving or passing another altitude separated from the first by the appropriate minimum, if severe turbulence is known to exist.

472.4You may request an aircraft to maintain a specified vertical separation from a preceding aircraft provided the aircraft are:

472.4 Phraseology:CLIMB/DESCEND WITH AT LEAST (number) THOUSAND FEET VERTICAL SEPARATION BELOW/ABOVE (aircraft identification).

A. climbing or descending; andB. in direct communication with each other.

472.5Following are specific limitations concerning the use of paragraph 472.4.A. Use this procedure between two aircraft only.B. Do not stipulate specified vertical speeds (rates of climb/descent).C. Do not require an aircraft to restrict its rate of climb when below the minimum IFR altitude.

472.5 C. Phraseology:WHEN LEAVING (minimum IFR altitude) CLIMB WITH AT LEAST (number) THOUSAND FEET VERTICAL SEPARATION BELOW (aircraft identification).

472.6Apply vertical separation between aircraft on reciprocal tracks from 10 minutes before until 10 minutes after their estimated passing time.

472.6 Diagram:

ATC 136

472.7You may discontinue vertical separation between aircraft on reciprocal tracks provided one of the following conditions is met: A. Both aircraft have reported by the same ground based NAVAID and, if at FL180 or above, are 2 minutes apart.

472.7 A. Note: The requirement to have the aircraft 2 minutes apart at FL180 and above compensates for overhead fix tolerance.472.7 A. Diagram:

B. Both aircraft have reported passing the same OMNI radial at an angle of 45 degrees or more and are:1. 2 minutes apart if 25 miles or less from the NAVAID producing the radial; or2. 4 minutes apart if more than 25 miles from the NAVAID producing the radial.C. DME and/or GPS position reports, determined in relation to a common point, indicate that aircraft have passed and are 5 miles apart, provided the outbound aircraft, if utilizing DME, is 15 miles or more from the DME facility.

472.7 C. Note 1: If the outbound aircraft from the common point is /G equipped, slant range is not a factor.472.7 C. Note 2: Paragraph 474.7 does not apply here.472.7 C. Diagram 1:

472.7 C. Diagram 2:

ATC 137

D. Both aircraft are below FL180 and both have reported passing each other, or both have reported passing the same visual fix.E. Both aircraft are in Class A airspace, are separated vertically by not more than 2,000 feet, and both aircraft report visual confirmation that they have passed each other. (N)

472.7 E. Note: Controllers should exercise caution if the proximity of other aircraft could make it difficult for either pilot to accurately identify the traffic.

472.8Unless lateral separation exists, apply vertical separation to an en route aircraft before and after the outer edge of the protected airspace, for a holding aircraft, or an aircraft on an instrument approach procedure, for the following time period:

472.8 Note: This paragraph does not apply when:A. the second of two aircraft in trail, separated by a longitudinal minimum, enters a hold; orB. the second of two aircraft in trail is put in a hold to achieve longitudinal separation.

A. 15 minutes. B. 10 minutes provided NAVAID coverage permits determination of position and speed at intervals not exceeding 40 minutes flying time. 474.9 B. Notes 1 and 2 apply to this paragraph.

472.9You may discontinue vertical separation between an en route aircraft and a holding aircraft or an aircraft on an instrument approach procedure provided the en route aircraft:

472.9 Diagram:

A. has reported over a fix within the appropriate protected airspace; andB. is 5 minutes from the outer edge of the holding or approach area.

473 LATERAL SEPARATION

473.1Apply lateral separation by requiring operation on different routes or in different areas or geographic locations as determined by the use of radar, NAVAIDs, RNAV, or visual reference to the ground.

473.2Do not use position information derived from visual reference to the ground for lateral separation purposes if the concerned aircraft is operating at FL180 or above.

473.2 Note: Some countries may vary this figure, but take always into consideration that a visual separation at high altitudes, either ground or traffic separation, may be impossible to achieve.

473.3Separate aircraft laterally by ensuring that the following protected airspaces do not overlap.

ATC 138

473.3 Diagram:

A. Holding areas.B. 1. low-level airways; and

2. the airspace to be protected, including additional protected airspace for change of direction, for:a. high-level airways; andb. off-airway tracks.

C. Initial, intermediate, final, missed approach and departure areas.

473.4If applying separation based on the airspace-tobe-protected concept, protect the airspace as depicted by the airspace planners, or determine the appropriate protected airspace dimensions in accordance with direction from unit management. (R)

473.5Geographical separation is a form of lateral separation positively indicated by position information derived from radar, NAVAIDs, RNAV or visual reference to the ground.

473.6Consider aircraft geographically separated if one aircraft is over a location whose fix tolerance area does not overlap: A. the fix tolerance area for other aircraft over different geographical locations; or

473.6 A. Diagram:

B. the protected airspace for other aircraft.

ATC 139

473.6 B. Diagram:

473.7If applying geographical separation, determine the appropriate fix tolerance area in accordance with the following:A. If position information is derived from radar, use the appropriate radar separation minimum. (N)(R)

473.7 A. Note: This does not apply if both aircraft are radar identified.B. If position information is derived from NAVAIDs, use the values as depicted by the airspace planners or in accordance with direction from unit management. C. If position information is derived from RNAV and you are controlling RNPC or CMNPS airspace, use the minima in sections 480 and 750 respectively.D. If position information is derived from visual reference to the ground, use caution to ensure that the aircraft's position is accurately defined.

473.8Consider an aircraft that is proceeding away from protected airspace to be geographically separated when it has reported crossing a radial that:

473.8 Diagram:

A. provides at least 5 degrees clearance from the area of overlap; andB. intersects the track of the traversing aircraft at an angle of at least 45 degrees.

473.9Unless alternate instructions are issued, apply restrictions to an aircraft approaching protected airspace, which ensure that there will be no overlap of protected airspaces.

473.9 Note 1: Protection of holding airspace, in this case, is part of the planning process. It does not necessarily mean that a hold will be affected, nor that a holding clearance will be issued. 473.9 Note 2: If an along track DME fix can be used as the point to effect the restriction, it must be at a sufficient distance to enable the aircraft to enter a hold, without there being overlap of airspace to be protected. The following table may be used, to determine the minimum distance that the DME fix may be from the airspace to be protected for the other aircraft, provided that the turn for any requiredholding is specified as being away from the protected airspace. For example, in 473.9 Diagram, right turns must be specified, to prevent an overlap of airspace to be protected.

ATC 140

12,000 and below — 15 DME13,000 to FL250 — 25 DMEFL260 and above — 35 DMEThe above distances are meant to be used on an ad hoc basis and, as such, are predicated on worst case scenarios. Lesser distances based on slower speeds and lower altitudes may be used, if they are confirmed through plotting or developed in accordance with the Holding Criteria Document and published in a unit directive.473.9 Diagram:

473.10If the airspace to be protected for turns of 16 degrees or more has not been depicted, protect the overflown side of the track as follows:

473.10 Note 1: Additional airspace need not be protected for aircraft completing a turn below FL180, nor in protected airspace extending 45 miles each side of track. In these cases, aircraft are expected to remain within the airspace protected for the track.473.10 Note 2: After the change of direction has been completed and the aircraft is back on course, the appropriate minima for the route may be used.

A. For turns of 16 degrees through 90 degrees:473.10 A. Diagram:

1. 14 miles from FL180 to FL230 inclusive; or2. 17 miles above FL230.

B. For turns of 91 degrees through 180 degrees, in addition to the 14/17 miles protected on the overflown side of the track, protect:

473.12OMNI-Track Separation.You may apply one of the following separation minima provided you establish aircraft on different specified radials of the same OMNI facility.

473.12 Note 1: The terms “inbound” and “outbound” are used in relation to the facility. Same direction aircraft are aircraft whose direction differs by less than 90 degrees. Opposite direction aircraft are aircraft whose direction differs by 90 degrees or more.473.12 Note 2: Where OMNI and DME facilities are collocated, you may use DME as follows, to satisfy the 15 miles requirement:

A. 30 degrees between: 473.12 A. Diagram:

ATC 143

1. Same direction, departing, outbound aircraft that are 15 miles or less from the facility.2. Same direction, en route, outbound aircraft that are 15 miles or less from the facility, provided the aircraft are 3 minutes or more from the facility.

B. 15 degrees between:1. Same direction, outbound aircraft provided at least one aircraft is more than 15 miles from the facility.

473.12 B. 1. Diagram:

2. Same direction, inbound aircraft provided the second aircraft is more than 15 miles, and 10 minutes or more, from the facility.

3. Opposite direction aircraft provided: a. they will pass at a point more than 15 miles from the facility; or

473.12 B. 3. a. Diagram:

b. the outbound aircraft is more than 15 miles from the facility.

ATC 144

473.13You may separate aircraft operating in the same or opposite direction by requiring operation on opposite sides of a track that can be accurately determined, provided an emergency condition necessitates this action

473.14For aircraft operating on the same or reciprocal tracks:A. maintain vertical separation until an aircraft diverging from an area of overlap, at an angle less than 45 degrees, is separated from the area of overlap by the greater of:

1. 5 minutes; or2. half the longitudinal separation minimum applicable; or

B. establish vertical separation before an aircraft converging to an area of overlap, at an angle of less than 45 degrees, reaches a point that is separated from the area of overlap by the greater of:

1. 5 minutes; or2. half the longitudinal separation minimum applicable.

474 LONGITUDINAL SEPARATION

474.1Separate aircraft longitudinally by a minimum distance expressed in units of time or in miles.

474.2Apply longitudinal separation expressed in units of time so that after one aircraft passes over a specific position a succeeding aircraft at the same altitude will not, on the basis of a control estimate, arrive over the same position within less than the minimum number of minutes specified by the appropriate separation minimum. (D)

C. to hold at a fix until a specified time; orD. to reverse heading.

474.4Establish longitudinal separation on the basis of position reports only if:A. both aircraft have reported over the same reporting point; orB. the following aircraft has confirmed not yet reaching the reporting point used by the leading aircraft.

474.5Initially establish longitudinal separation, expressed in miles, on the basis of position reports from the concerned aircraft determined in relation to a common point.

474.5 Note 1: You may continue to provide longitudinal separation based on position reports in relation to adjacent DME facilities, provided both aircraft are en route between the same two facilities and the lead aircraft has changed over to the next facility along the route.

ATC 145

474.5 Note 2: Common point may be the same DME NAVAID, the same GPS reference position or a collocated DME NAVAID/GPS reference position.474.5 Note 3: GPS receivers typically display distance information in relation to the next waypoint. Pilots can provide distance information to other fixes upon request. When using GPS position reports to establish longitudinal separation, controllers must ensure that the distance reports are in relation to a common point.474.5 Note 4: Position reports based on RNAV and GPS will be provided in miles (e.g. 30 miles from Sumspot VOR). When position reports are based on DME, pilots will state DME (e.g. 30 DME from Sumspot VOR).

474.6Apply longitudinal separation expressed in miles by:A. maintaining DCPC except when using DME and/or GPS to establish vertical separation; and B. requesting DME and/or GPS position reports, as necessary, to ensure the required separation is being maintained or increased.

474.7To establish longitudinal separation between aircraft providing a mix of DME and GPS position reports, the DME aircraft must be either 10,000 feet or below or outside of 10 miles from the DME NAVAID, to account for DME slant range.

474.7 Note: Once longitudinal separation is established, there is no requirement to impose another form of separation, while the DME aircraft transits the DME NAVAID within 10 miles, above 10,000 feet.

474.8You may request aircraft to maintain a specified longitudinal separation provided the aircraft are:

474.8 Phraseology:MAINTAIN AT LEAST (number) MILES/MINUTES SEPARATION FROM (aircraft identification).

A. in direct communication with each other; andB. using NAVAIDs that permit determination of position and speed at intervals not exceeding 40 minutes flying time.

474.9Separate aircraft on the same track by using one of the following minima:A. 15 minutes. B. 10 minutes provided NAVAID coverage permits determination of position and speed at intervals not exceeding 40 minutes flying time.

474.9 B. Note 1: The phrase “NAVAID coverage permits determination of position and speed” means that ATC must obtain a position report at least once every 40 minutes to continue to apply longitudinal minimum of 10 minutes or less.474.9 B. Note 2: In addition to the actual NAVAID fixes used for position reports, radials from VHF NAVAIDs, DME arcs, bearings from a NDB, waypoints from RNAV and full degrees of longitude or latitude from GPS equipped aircraft may also be used. If any of the above are used, the fix positions must be such that when considering the speed of the aircraft, the estimates and subsequent position reports between reporting fixes are no more than 40 minutes flying time apart.474.9 B.

480 RNPC

481 RNPC GENERAL

481.1Apply the criteria and procedures in this section to RNPC certified aircraft and to aircraft with an equipment suffix /G operating within RNPC airspace, unless otherwise indicated.

481.1 Note: Certification to operate in accordance with RNPC will be indicated by the appropriate suffix on domestic flight plans. Aircraft indicating certification to operate in NAT MNPS airspace are considered certified for RNPC airspace. Foreign carriers overflying may be considered certified, on the basis that they have flight planned into the airspace and their route of flight indicates the use of RNAV equipment. If for any reason (aircraft type, route, track keeping etc.) you suspect an aircraft may not be certified, you should query the pilot and, depending upon the response, take appropriate action.

481.2You may clear an aircraft “via RNAV direct” to indicate the method of navigation expected to be used. (P)

481.2 Phraseology:VIA RNAV DIRECT.

482 RNPC VERTICAL SEPARATION

482.1You may discontinue vertical separation between RNPC certified aircraft on reciprocal tracks, provided RNAV positions indicate they have passed and are 30 miles apart.

483 RNPC LATERAL SEPARATION

483.1For RNPC certified aircraft protect:

483.1 Diagram:

A. 10 miles each side of track, if operating off airways; orB. the airspace to be protected for an airway, if operating on airways.

484 RNPC LONGITUDINAL SEPARATION

484.1Apply longitudinal separation, expressed in miles, by:A. maintaining DCPC; andB. requesting position reports determined through RNAV, as necessary, to ensure required separation is maintained or increased; orC. use of radar.

ATC 159

484.2Advise RNPC certified aircraft to use DME distance if applying DME separation.

484.2 Phraseology:USE DME DISTANCES.

484.3Separate RNPC certified aircraft operating on the same track, or crossing tracks, by a minimum of 10 minutes. (N)

484.3 Note: Aircraft using RNAV have the capability to establish positions at any point along track.

484.4Separate RNPC certified aircraft operating on the same track by 30 miles, provided distance is determined through RNAV from a common point.

484.4 Diagram:

484.5You may separate RNPC certified aircraft that are transitioning from a radar to a non radar environment, but have not reported over a common point, by 30 miles provided you ensure through the use of radar or RNAV distance that the minimum will exist at the common point from which the aircraft will follow the same track or continuously diverging tracks.

484.5 Note: As necessary, request position reports from common points to ensure the required separation is being maintained or increased.

484.6Separate RNPC certified aircraft on crossing tracks by 30 miles, as determined by RNAV distance from the crossing point.

484.7If aircraft are on crossing tracks or converging to or diverging from an area of overlap at an angle of less than 45 degrees, establish vertical separation before the RNPC certified aircraft reaches a point 15 miles, as determined by RNAV, from the area of overlap.

484.7 Note 1: The other aircraft need not be RNPC certified.484.7 Note 2: DCPC is not required in this case.484.7 Note 3: If an RNAV position along the track of the approaching aircraft can be used as the point to effect the restriction, it must be at least 15 miles from the area of overlap. Since the pilot has continuous readout of distance to go, there is reasonable assurance that the restriction will be achieved without holding.484.7 Note 4: You may use the following table to determine the distance from various protected airspaces, at whichvertical separation must be established, as measured from where the tracks cross.

ATC 160

484.7 Note 5: In lieu of specifying a RNAV distance, vertical separation may be established or discontinued, where the aircraft crosses the nearest full or half degree of latitude or longitude that will provide the required separation. 484.7 Diagram:

485 RNPC LONGITUDINAL SEPARATION — MACH-NUMBER TECHNIQUE

485.1Apply longitudinal separation minima using Mach-number technique, to RNPC certified aircraft operating within or proceeding to or from RNPC airspace.

485.2Assign the appropriate Mach-number, for the duration of the application, whenever Machnumber is being used for separation.

485.2 Note: When reclearing aircraft on entry into RNPC airspace from oceanic airspace, and separation is based on Mach-number technique, it is necessary that the Mach-number form part of the clearance.

485.3Ensure that the required separation is being maintained or increased while applying Machnumber technique by obtaining, as necessary, confirmation from the pilot that the assigned Mach-number is being maintained.

485.3 Phraseology:CONFIRM MAINTAINING MACH (number).485.3 Note: Requests for confirmation of Mach-number may be done in conjunction with a position report.

ATC 161

485.4Separate RNPC certified aircraft by 10 minutes provided:

485.4 Diagram:

A. Mach-number technique is used; B. aircraft are in level flight, climbing, or descending;C. aircraft are operating on the same track or continuously diverging tracks;D. aircraft have reported over a common point; and (R)E. the required longitudinal separation will be maintained until tracks diverge; and, when tracks diverge, the required lateral separation, and at least 5 minutes longitudinal separation, will exist at the next significant point.

485.4 E. Diagram:

485.5You may separate aircraft that have not reported over a common point, as specified in 485.4 D., provided you ensure through the use of radar, DME, or RNAV distance, that the minimum will exist at the common point from which the aircraft will follow the same track or continuously diverging tracks.

485.5 Diagram:

ATC 162

485.6You may reduce the minimum specified in 485.4 in accordance with the following table, provided:

485.6 Note: The 5 minute longitudinal separation minimum is no longer required, if the aircraft are following continuously diverging tracks and the required lateral separation will be achieved at the next significant point.

A. the preceding aircraft is maintaining a greater Mach-number than the succeeding aircraft; andB. 1. the aircraft reported over a common point; or

485.6 B. 1. Note: The fix tolerance area for the fix derived from ground based NAVAIDs shall not exceed that of an NDB at the appropriate altitude.

2. radar, DME, or any RNAV distance is used to ensure that the appropriate time interval exists and will exist at the common point.

485.7Separate a faster succeeding aircraft from a preceding aircraft, by ensuring that not less than 10 minutes longitudinal separation is maintained:

485.7 Note 1: Determine the extra time required by following the column of the slower aircraft groundspeed until it intercepts the difference in Mach column. Multiply this time by the number of hours the faster aircraft will fly from the point of application to the point of destination/divergence/other separation, to determine the additional longitudinal separation necessary.485.7 Note 2: Where automated systems provide conflict prediction, there is no requirement to use the table to determine the appropriate separation minimum.485.7 Note 3: Groundspeed based on RNAV systems, or radar displayed information, is acceptable.

ATC 163

A. until tracks diverge, provided the required lateral separation and at least 5 minutes longitudinal separation will exist at the next significant point; orB. to a point at which another form of separation will be achieved.

486 RNPC PARALLEL OFFSET PROCEDURES - NON-RADAR ENVIRONMENT

486.1In a non-radar environment, you may use parallel offset techniques provided:

486.1 Note 1: Parallel offset is a feature of some RNAV systems and enables the aircraft to fly offset from a specific route by a specific number of miles.486.1 Note 2: Aircraft will normally not diverge to the offset track by more than 45 degrees. Some RNAV systems are limited in the offset distance.

A. aircraft are operating within RNPC High Level Controlled Airspace;B. the procedure is used to accomplish an altitude change;C. aircraft are operating on same direction tracks;D. the aircraft to be offset;

1. is RNPC certified; and 2. confirms the capability to offset.

486.1 D. 2. Phraseology:ADVISE IF ABLE TO PROCEED PARALLEL OFFSET.

E. the minimum offset value ensures at least 10 miles separation from the edge of the protected airspace of the other aircraft;

486.1 E. Note: The other aircraft is not required to be RNPC certified.486.1 E. Diagram:

ATC 164

F. vertical separation is maintained until the offset aircraft reports established on the parallel offset track. (P)486.1 F. Phraseology:PROCEED OFFSET (number) MILES (right/left) OF CENTRELINE (track/route) REPORT ESTABLISHED ON PARALLEL OFFSET.— or —PROCEED OFFSET (number) MILES (right/left) OF CENTRELINE (track/route), AT (significant point/ time) UNTIL (significant point/time) REPORT ESTABLISHED ON PARALLEL OFFSET.

486.2When the offset aircraft reports established on the parallel offset track, you may issue a clearance for an altitude change to either aircraft.

486.3Request reports to determine the reestablishment of vertical separation.

486.4Unless required for further control purposes, once vertical separation is re-established, cancel the parallel offset, or clear the offset aircraft to a downstream waypoint or fix on its route of flight.

503.8You may use validated altitude readouts to determine aircraft altitudes as follows:A. Consider an aircraft to be maintaining an altitude, when its altitude readout value is within 200 feet of the assigned altitude.

503.8 A. Example:Consecutive readouts of 312, 310, 310, 308, 310 and 311 would indicate that an aircraft is maintaining FL310.

B. Consider an aircraft to have reached an altitude, when its altitude readout value has been within 200 feet of the assigned altitude for 4 consecutive readout updates.

503.8 B. Example:Consecutive readouts of 146, 144, 143, 142, 140, 141 and 141 would indicate that an aircraft has descended to and is maintaining 14, 000 feet ASL.

C. Consider an aircraft to have vacated an altitude, when its altitude readout value has changed by 300 feet or more, in the appropriate direction, from the value that prevailed while the aircraft was in level flight.

503.8 C. Note 1: The “starting point” is the aircraft's prevailing readout while in level flight, which may differ from the equivalent altitude figure. In 503.8 C. Example below, where the prevailing value during level flight was 139, the condition is met when the readout shows 136, not 137.503.8 C. Note 2: The VMI has both altitude and time VSPs. No VMI indication will be displayed for an aircraft whose rate of climb or descent falls outside the adapted VSPs for VMI.503.8 C. Example:Consecutive readouts of 139, 139, 139, 138, 137, and 136 would indicate that an aircraft has vacated 14,000 feet in descent.

D. Consider an aircraft to have passed an altitude, when its altitude readout value has changed by 300 feet or more in the appropriate direction.

503.8 D. Example:Consecutive readouts of 060, 062, 063 and 068 would indicate that a climbing aircraft has passed 6,500 feet ASL.

503.9Do not use invalidated altitude readouts to determine an aircraft's altitude. However, they may be used to:A. observe whether an aircraft is in level flight, climbing or descending;B. observe rates of climb or descent; or (N) 503.9 B. Note: If an aircraft climbs or descends at a very high rate, its readout values may fall behind the aircraft's actual altitude and the aircraft will coast.C. provide traffic information.

503.10Do not use altitude readouts of aircraft under the jurisdiction of another controller for determining aircraft altitudes unless:A. the other controller has confirmed the aircraft's altitude; orB. on hand-off the transferring controller does not inform you that an aircraft's altitude readout is invalid or not validated

503.11Do not use altitude readouts for aircraft when:A. the site altimeter setting for the geographic region concerned is below 26.00 or above 33.00 and the aircraft is operating below FL180;B. the site altimeter setting for the geographic region concerned is below 29.02 and the aircraft is operating at or above 17,000 ft and below FL180;C. the site altimeter setting for the geographic region concerned is below 28.02 and the aircraft is operating at or above 16,000 ft and below FL180; orD. the site altimeter setting for the geographic region concerned is below 27.02 and the aircraft is operating at or above 15,000 ft and below FL180.

505.2Instruct an aircraft to resume position reporting before terminating radar service.

505.2 Phraseology:RESUME POSITION REPORTS. RADAR SERVICE TERMINATED.

506 PARALLEL OFFSET PROCEDURES

506.1Use the parallel offset technique if an operational advantage is gained, provided;

506.1 Note 1: Parallel offset is a feature of some RNAV systems. This feature enables an aircraft to fly offset from a specific route by a specific number of miles. This permits controllers to apply radar separation without radar vectoring.506.1 Note 2: Aircraft will not normally diverge to the offset track by more than 45 degrees. Some RNAV systems are limited in the offset distance.

A. except as specified in 486.1, it is used only in a radar environment; B. the aircraft confirms the capability to offset; and

506.1 B. Phraseology:ADVISE IF ABLE TO PROCEED PARALLEL OFFSET.

C. the minimum offset value ensures the appropriate radar separation minimum will exist. 506.1 C. Phraseology:PROCEED OFFSET (number) MILES (right/left) OF CENTRELINE (track/route) AT (significant point/ time) UNTIL (significant point/time).

506.2Cancel the parallel offset if it is no longer required.

506.2 Phraseology:CANCEL OFFSET.

507 SAFETY ALERT

507.1Issue a safety alert to an aircraft if you are aware the aircraft is at an altitude which, in your judgment, places it in unsafe proximity to the terrain, an obstruction or another aircraft.

507.1 Phraseology:LOW ALTITUDE ALERT, VERIFY YOUR ALTITUDE IMMEDIATELY, ALTIMETER IS (setting).— or —THE MINIMUM IFR ALTITUDE IN YOUR AREA IS (altitude). ALTIMETER IS (setting).— or —TRAFFIC ALERT (position of traffic, if time permits), ADVISE YOU TURN RIGHT/LEFT (specific heading, if appropriate), or CLIMB/DESCEND (specific altitude, if appropriate) IMMEDIATELY.507.1 Note 1: Every situation where a safety alert should be passed may not be readily apparent; however, controllers should remain vigilant of such situations and issue safety alerts when such situations are recognized. Conditions such as workload, traffic volume, and the lead time to react, are all factors in determining whether it is reasonable for controllers to observe and recognize such situations.507.1 Note 2: You may be made aware of an unsafe proximity from; Mode C altitude readouts, observations by another sector or unit, or from pilot reports.

ATC 175

508 DEVIATION FROM ASSIGNED AIRSPACE

508.1Inform an aircraft if you observe that:A. it appears it will deviate, or it has deviated from its assigned route or holding area;B. the altitude readout indicates it has deviated by 300 feet or more from its assigned altitude, or

508.1 B. Phraseology:YOUR ALTITUDE READOUT IS (altitude), ALTIMETER IS (setting). VERIFY YOUR ALTITUDE.

C. the altitude readout indicates that it has deviated by 200 feet from its assigned altitude and the VMI indicates that the aircraft is continuing its climb or descent away from the assigned altitude.

508.1 C. Note 1: 508.1 B. Phraseology and 508.1 B. Reference apply here also.508.1 C. Note 2: An aircraft at a constant altitude and maintaining a previously assigned altimeter setting can appear to change altitude as it traverses system tiles.

510 IDENTIFICATION

511 RADAR IDENTIFICATION

511.1You may consider an aircraft identified, provided one of the following conditions is met:A. The aircraft is observed on radar to be in a position, within one mile of the end of the runway used for takeoff, that is consistent with the time of takeoff and the route of flight or assigned heading of a departing aircraft.B. The aircraft is observed on radar to be over a fix, which is indicated on the radar display, that is consistent with a position report received directly from the aircraft, provided the track is observed to be consistent with the route of flight or reported heading of the aircraft.

511.1 B. Note: A fix may be used as a reference for establishing aircraft identification, provided the position of the fix is accurately indicated on the radar display.

C. The aircraft is observed on radar to be in a position, relative to OMNI and DME NAVAIDs which are indicated on the radar display, that is consistent with a position report received directly from the aircraft in the form of a DME fix, provided that the track is observed to be consistent with the route of flight or reported heading of the aircraft.

511.1 C. Note: Caution should be exercised, if using a position report to identify an aircraft operating at high altitude, or reporting over an intersection which is a considerable distance from a NAVAID. Under these circumstances, aircraft often cannot accurately determine their precise position.

D. The aircraft is observed on radar to have carried out a specified identifying turn of at least 30 degrees, provided:

511.1 D. Note: A turn that would cause an aircraft to follow an airway or a frequently used flight path should be avoided. These circumstances could lead to missidentification of the aircraft.1. except in the case of a lost aircraft, a position report received directly from the aircraft indicates that the aircraft is within radar coverage of the area being displayed;2. only one aircraft is observed to have carried out the specified turn; and3. the track is observed to be consistent with the heading or track of the aircraft both before and after completion of the turn.

E. The appropriate change in the PPS is observed after the aircraft is instructed to operate the “Ident” feature of its transponder.

511.1 E. Phraseology:SQUAWK IDENT.SQUAWK (code) AND IDENT.

F. The appropriate change in the PPS is observed after the aircraft is instructed to change from one code to another.

511.1 F. Note: This change in PPS will occur only if the aircraft is asked to change to a code which will cause correlation to take place.

G. The PPS disappears or changes to a PSR symbol after the aircraft is instructed to change its transponder to “standby” and the PPS reappears or changes back to an SSR symbol after the aircraft is requested to return the transponder to normal operation.

511.1 G. Phraseology:SQUAWK STANDBY — SQUAWK (code).511.1 G. Note: Care should be taken to ensure that a period of time sufficient to ascertain that the loss of PPS resulted from the aircraft's action.

H. The position of the PPS on the tower display is consistent with the position of the aircraft observed visually by the airport controller.I. Identification was transferred by a hand-off.

511.2Use more than one of the procedures contained in 511.1, or use the same procedure more than once, if you have any doubt concerning the identity of a particular aircraft.

511.2 Note: Doubt may be caused by:A. the position or movement of other aircraft.B. the observation of more than one aircraft responding to an identification instruction; orC. other circumstances.

511.3If it appears that identification may become doubtful, take immediate action to ensure identification is maintained.

511.4If identification becomes doubtful or is lost, take immediate action to:

511.4 Note: Identification may be doubtful because of:

ATC 177

A. momentary loss of the PPS;B. coasting of a PPS;C. merging of PPSs;D. display clutter;E. ambiguous PPSs; orF. other circumstances.

A. re-identify the aircraft; orB. terminate radar service and provide nonradar separation.

511.5Inform the aircraft when radar identification is established or lost.

511.5 Phraseology:RADAR IDENTIFIED (position if required).RADAR IDENTIFICATION LOST.511.5 Note: On receipt of a hand-off it is not necessary to reinform the aircraft that it is radar identified, when communication is established.

511.6Once initial identification has been established, considering local regulations, by a unit in accordance with 511.1 and the aircraft is in adjacent airspace where radar service is normally provided, you may use the aircraft identification element of the data tag to consider the aircraft identified.

511.7Consider identification to be lost if a correlated PPS ceases to be displayed after “CST” has been displayed in its data tag unless:

511,7 Note: IVAC software currently does not support CST function.

A. you are able to maintain identification of an uncorrelated PPS being displayed for the aircraft; orB. the PPS recorrelates within a sufficiently short period of time that, considering the progress of the aircraft you have no doubt about the aircraft's identity.

512 HAND-OFF — TRANSFERRING CONTROLLER

512.1Provide a hand-off to another sector or unit if an aircraft will enter that sector's or unit's airspace;and 512.1 Note: A hand-off does not constitute a transfer of control, however, coordination of control transfer may be required or carried out coincidentally with a handoff.A. you are applying radar separation between the aircraft concerned and another aircraft that:

ATC 188

A. Separate aircraft on approach such that the position of the leading aircraft is determined to be clear of the ILS critical area before the following aircraft is 4 miles from the end of the instrument runway used by the preceding aircraft.

534.1 A. Note 1: A preceding arriving aircraft could adversely affect the integrity of the localizer signal for a following aircraft on a Category II ILS approach.534.1 A. Note 2: Actual aircraft separation will depend upon runway and taxiway configuration. Therefore, the aircraft in trail spacing required to comply with this minimum shall be determined by the unit.

B. Separate departing aircraft from arriving aircraft such that the departing aircraft has overflown the localizer antenna location before the arriving aircraft is 4 miles from the end of the instrument runway to be used by the arriving aircraft.

534.1 B. Note: A departing aircraft over-flying the localizer at close range, could adversely affect the integrity of the localizer signal for an arriving aircraft on a Category II ILS approach.

534.2When Category II ILS approaches are being conducted, vector aircraft such that they will be established on the localizer in level flight at least 2 miles before glide path interception.

534.2 Note: This procedure will permit aircraft to perform an automatic coupled approach. In most instances, the glide path intercept altitude will be at the minimum vectoring altitude.

535 CATEGORY III ILS APPROACHES

535.1Provided ASDE is functioning, when Category III ILS approaches are being conducted:A. separate aircraft on approach such that the position of the leading aircraft as determined by ASDE is clear of the ILS critical area before the following aircraft is 4 miles from the end of the instrument runway used by the preceding arriving aircraft; or

535.1 A. Note 1: Actual aircraft separation will depend upon runway and taxiway configuration. Therefore, the unit shall determine the aircraft-in-trail spacing to comply with this minimum.535.1 A. Note 2: A preceding arriving aircraft in the critical area could adversely affect the integrity of the localizer signal for a following aircraft on a Category III ILS approach.

B. separate aircraft departing from the same runway being used for an arriving aircraft such that the departing aircraft has overflown the localizer antenna location before the arriving aircraft is 4 miles from the end of the instrument runway.

540 VECTORING

541 GENERAL

541.1Allow aircraft operating on conventional SIDs or STARs, RNAV SIDs or STARs and RNAV routes to conduct their own navigation to the extent possible.

541.2Vector an aircraft if:A. necessary for separation purposes except on ranges greater than 600 miles left to right; (N)

541.2 A. Note: Normally, using a range greater than 600 miles is related to the fact of acting as a FSS station or Radio control (Oceanic control), therefore, even though this kind of services are not engaged in radar service provision, enough precision for providing vectores is not expected.

B. required by noise abatement procedures;C. you or the aircraft will gain an operational advantage; orD. the aircraft requests it.

541.3If you initiate vectoring, inform the aircraft of:A. the purpose of vectors; and/or

541.3 A. Phraseology:VECTORS FOR (sequencing, spacing, traffic, etc.).VECTORS FOR (downwind, base leg, etc.).

542 APPLICATION OF VECTORS

542.1You may vector an aircraft into Class G airspace provided you: A. inform the aircraft; andB. obtain the aircraft's approval.

542.2You may vector a VFR aircraft provided:

542.2 Note: Accepting a vector does not relieve a VFR aircraft from its responsibility for:A. avoiding other aircraft;B. avoiding flight in IMC; andC. maintaining adequate obstacle clearance.

A. the aircraft is in, or is about to enter, airspace where radar service to VFR aircraft is provided; B. the aircraft requests it;C. you suggest it and the aircraft accepts it; orD. you consider it necessary for flight safety.

542.3You should consider surrounding terrain before you assign or suggest an altitude to a VFR aircraft.

542.4Before vectoring an aircraft, ensure that it can be established on a non-radar route within radar coverage.

ATC 190

542.5Cancel a previously assigned SID, provided:

542.5 Phraseology:SID CANCELLED.542.5 Note: It is not necessary to vector the aircraft over a SID termination fix if an operational advantage will be gained either by you or the aircraft.

A. you have specified the SID termination fix as the location for the aircraft to expect climb to an operationally suitable altitude or flight level; andB. you vector the aircraft on a route that will not take the aircraft over the SID termination fix.

543 METHODS OF VECTORING

543.1Vector aircraft by using one of the following methods:

543.1 Note: These provisions do not apply if you are using “nogyro” techniques, as explained in 543.2.A. Specify the heading to be flown.

543.1 A. Phraseology:FLY HEADING (number).DEPART (fix) ON HEADING (number).MAINTAIN PRESENT HEADING.

B. Specify the direction of the turn and the heading to be flown after completion of the turn. 543.1 B. Phraseology:TURN LEFT/RIGHT HEADING (number).

C. Specify the direction of the turn and the number of degrees to turn. 543.1 C. Phraseology:TURN LEFT/RIGHT (number) DEGREES.

543.2If an aircraft does not have a serviceable directional gyro, take the following actions:A. Determine whether the aircraft's desired rate of turn is rate one or rate one half.

543.2 A. Note: A rate one turn is a turn at the rate of 3 degrees per second.B. Instruct the aircraft to make turns at the agreed rate and to start and stop turns as directed.

543.2 B. Phraseology:DISREGARD YOUR GYRO, MAKE ALL TURNS AT RATE ONE/RATE ONE HALF. START AND STOP ALL TURNS ON THE COMMAND “NOW”.

C. Vector the aircraft by specifying the direction of turn and when to start and stop turn. 543.2 C. Phraseology:TURN LEFT/RIGHT NOW.then —STOP TURN NOW.

544 SPEED ADJUSTMENT

544.1Instruct a radar controlled aircraft to adjust its speed, provided this action is necessary to achieve or maintain required spacing or to minimize vectoring.

544.2Express a speed adjustment:A. in units or multiples of 10 knots, based on IAS, or;

544.2 A. Note: Aircraft complying with speed adjustments are expected to maintain a speed within plus or minus 10 knots of the specified speed.

B. by the assignment of specific Mach number to be maintained provided the aircraft is a turbojet operating in high level airspace.

544.3Instruct an aircraft to do one of the following:

544.3 Note: Use the following table as a guideline when making speed adjustments.

ATC 191

Some aircraft may be unable to maintain a speed as high or as low as those specified in this table. Turbojet aircraft conducting straight-in approaches in IMC should not be requested to maintain a speed in excess of 160 knots if less than 10 miles from the runway. Consider local regulation.

A. State its speed/Mach number. 544.3 A. Phraseology:SAY AIRSPEED.SAY MACH-NUMBER.

B. Maintain its present speed/Mach number or a speed/Mach-number equivalent to or less than that of a preceding or succeeding aircraft.

544.3 B. Phraseology:MAINTAIN PRESENT SPEED or MACH NUMBER.MAINTAIN SPEED (specified speed) KNOTS.MAINTAIN MACH (specified MACH).REDUCE TO MINIMUM APPROACH SPEED.

C. Increase or decrease its speed to a specified speed/Mach number. 544.3 C. Phraseology:INCREASE/REDUCE SPEED TO (specified speed in knots or Mach number). Speed reduction prior to descent —REDUCE SPEED TO (specified speed by number of knots), THEN DESCEND AND MAINTAIN (altitude). Speed reduction following descent —DESCEND AND MAINTAIN (altitude), THEN REDUCE SPEED (to specified speed/by number of knots/to Mach number).544.3 C. Note: Simultaneous descent and speed reduction can be a difficult manoeuvre for some types of turbojet aircraft. It may be necessary for the pilot to level off temporarily and reduce speed, prior to descending. Specifying which action is to be accomplished first, will remove any doubt the pilot may have concerning controller intent or priority.

D. Increase or decrease its speed by a specified amount or to an assigned Machnumber.544.3 D. Phraseology:INCREASE/REDUCE SPEED BY (specified number of knots or Mach number).

E. Avoid exceeding a specified speed. 544.3 E. Phraseology:DO NOT EXCEED SPEED (speed) Knots.DO NOT EXCEED MACH (Mach number).

544.4Do not assign speeds that are lower than those specified in 544.3 Note without prior coordination with the aircraft.

544.4 Phraseology:ARE YOU ABLE TO MAINTAIN (specified speed)?— or —WHAT IS YOUR MINIMUM APPROACH SPEED? followed by —REDUCE TO (specified speed).

544.5Do not issue speed adjustment requests that necessitate alternate decreases and increases in speed.

544.6Do not specify a minimum speed, if a higher speed would suffice.

ATC 192

544.7If you have reason to believe that an aircraft may be unable to maintain a speed as high as, or as low as, those specified in 544.3 Note, prefix the request with the words ”if practicable”.

544.7 Phraseology:IF PRACTICABLE, INCREASE/REDUCE SPEED TO (specified speed in knots/Mach number).

544.8Advise an aircraft to resume normal speed when application of a speed adjustment is no longer necessary, except when the aircraft has been cleared for an approach.

544.8 Phraseology:RESUME NORMAL SPEED.544.8 Note: An approach clearance supersedes a speed adjustment request, and aircraft are expected to make their own speed adjustments, to complete the approach. If you require aircraft to adjust speed while on approach, restate the request.

545 POSITION INFORMATION

545.1Inform an aircraft of its position when:A. identification is established by an identifying turn;B. vectoring is terminated, unless you know the pilot has the information; C. the aircraft requests the information; orD. you deem it necessary.

545.1 D. Note: Pilots' situational awareness may be degraded by NAVAID failures; manoeuvers to avoid weather or unfamiliarity with airspace.

545.2Describe the position of an aircraft in relation to a fix, airway, course, or radial that is indicated on the radar display.

545.2 Phraseology:OVER/PASSING (FIX). (Number) MILES (direction) OF (fix). (Name of NAVAID) (specified) RADIAL IS (number) MILES TO YOUR LEFT/RIGHT INTERCEPTING/ CROSSING (name of NAVAID) (specified) RADIAL. CROSSING/JOINING/DEPARTING (airway).

546 OBSTRUCTION CLEARANCE

546.1Ensure that adequate terrain clearance is provided if you vector an aircraft off a non-radar route.

546.2Provide terrain clearance by requiring the aircraft to operate at an altitude which is at or above the minimum IFR altitude specified for the area within which the aircraft is being vectored.

546.2 Note: When vectored away from a non-radar route, aircraft maybe unable to determine their exact position. In such cases, responsibility for ensuring avoidance of collision with terrain or obstructions must be assumed by the controller.

546.3You may authorize a radar controlled aircraft to climb or descend while maintaining terrain clearance visually provided:A. 1. the aircraft requests it; or

2. you suggest it and the aircraft accepts it;and

B. separation, other than visual separation, is provided from all other IFR and CVFR aircraft. 546.3 B. Phraseology:ARE YOU ABLE TO MAKE A CLIMB/DESCENT TO (altitude) WHILE MAINTAINING TERRAIN CLEARANCE VISUALLY?— followed by —CLIMB/DESCEND VISUALLY FROM (altitude) TO (altitude)— and, if necessary —IF NOT POSSIBLE, (alternate instructions) AND ADVISE.

ATC 193

546.3 B. Note 1: Normally, when radar vectoring an aircraft, ATC must ensure that appropriate terrain clearance is provided. When executing a visual climb or descent while on radar vectors, the pilot will ensure terrain clearance.546.3 B. Note 2: While maintaining terrain clearance visually, the pilot is expected to operate in visual meteorological conditions rather than in accordance with the visual flight rules.

546.4Vector an aircraft at an established minimum vectoring altitude that does not provide adequate clearance above a prominent obstruction by one of the following minima:A. 5 miles provided the position of the prominent obstruction is indicated on the radar display; orB. 3 miles if:1. terminal control service is being provided;2. a maximum range of 60 miles is displayed on the radar display; and3. the prominent obstruction is enclosed within a buffer. (N)(D)

546.4 B. 3. Note:The prominent obstruction must be enclosed within a depicted circular buffer with an outer boundary at a distance from the obstruction that corresponds to the required radar separation.546.4 B. 3. Diagram:

547 TERMINATION OF VECTORING

547.1You may terminate vectoring of an aircraft provided it is:A. cleared for an approach.B. cleared to hold; orC. established on a non-radar route.

547.1 C. Note: An aircraft that is on a track that will intercept the “on course” within a reasonable distance is considered to be established on a non-radar route.

547.2Inform the aircraft, if vectoring is discontinued, except when the aircraft has been cleared for an approach.

547.2 Phraseology:(Position) RESUME NORMAL NAVIGATION.

547.3When an aircraft has been vectored off its cleared route, clear the aircraft to the next waypoint or fix on its route of flight, unless the pilot requests otherwise.

547.4Inform the aircraft if you intend to continue vectoring after the aircraft has been cleared for the approach.

ATC 194

550 RADAR DEPARTURES

551 GENERAL

551.1Use standard departure routings, altitudes, and procedures to reduce coordination if practicable.

551.2Base an initial departure clearance on nonradar separation minima and non-radar routes, to provide for radar or communication failure.

551.2 Note: This provision does not apply if aircraft will be radar separated in accordance with 531.2.

551.3Include the following instructions in a departure clearance as applicable:A. The initial heading to be flown, if the aircraft is to be vectored immediately after takeoff.

551.3 A. Note: Aircraft instructed to “climb runway heading” or a SID, or departure procedure for which no specific heading is published, are expected to fly the heading that corresponds with the extended centreline of the departure runway until otherwise instructed. Drift correction will not be applied; e.g. Runway 04, magnetic heading of the centreline is 044 degrees, aircraft will fly heading 044 degrees.

B. The appropriate instructions concerning transponder operation, if a secondary radar reply is required immediately after takeoff.

551.3 B. Phraseology:SQUAWK (number) JUST BEFORE TAKEOFF.

564.2 A. Diagram:

B. any distance, but not closer to the runway than the FAF, provided:1. the reported ceiling is 3,000 feet AGL or above and the ground visibility is 3 miles or more;2. no known or suspected wind shear conditions exist; and3. the aircraft has received prior notification of the vectoring procedure. 564.2 B. 3. Note: Prior notification to the aircraft may be accomplished by either ATIS or DCPC.

564.3If requested by the aircraft, you may vector it to intercept the final approach course at any distance, but not closer to the runway than the FAF.

564.4Inform the aircraft if it will be vectored through the final approach course.

564.4 Phraseology:YOU WILL BE VECTORED THROUGH THE FINAL APPROACH COURSE FOR SPACING/DESCENT.564.4 Note: When vectoring aircraft through the final approach course consideration must be given to wake turbulence separation as given in 533.

564.5Clear an aircraft flying an RNAV STAR for descent in sufficient time to be at the published minimum altitude, prior to crossing the Final Approach Course Fix (FACF).

564.5 Note 1: The published minima at the Final Approach Course Fix allows the aircraft to intercept the glide path from below.564.5 Note 2: When the aircraft has been cleared for an RNAV STAR and if an approach clearance is not issued prior to the aircraft turning final, the aircraft will intercept the localizer and fly inbound, maintaining the last assigned altitude.

565 MISSED APPROACHES

565.1Issue alternate missed approach instructions that will provide non-radar separation if there is a possibility of successive missed approaches.

565.1 Note 1: This provision does not apply if aircraft will be radar separated in accordance with 531.2.

566 VISUAL APPROACHES

566.1You may clear an aircraft for a visual approach provided:

566.1 Note: Visual approaches may be requested by pilots or initiated by controllers to gain an operational advantage for arrivals operating in good weather conditions. Pilots cleared for a visual approach are responsible for compliance with published noise abatement procedures, wake turbulence separation and avoidance of Class F airspace.

A. the reported ceiling at the destination airport is 500 feet or more above the minimum IFR altitude and the ground visibility is three statute miles or more;

566.1 A. Note: The MVA is the lowest usable minimum IFR altitude to be used at those locations where a MVA is established. Where a MVA is not established, the minimum IFR altitude for the airspace concerned is the lowest usable altitude.

ATC 204

B. separation, other than visual separation, is provided from other IFR or CVFR aircraft except that the aircraft being vectored may be instructed to maintain visual separation from preceding arriving IFR or CVFR aircraft when cleared for a visual approach;

566.1 B. Phraseology:FOLLOW (traffic)— or —MAINTAIN VISUAL SEPARATION FROM (traffic) ON VISUAL APPROACH TO RUNWAY (number).566.1 B. Note: At controlled airports an IFR aircraft may be instructed to maintain visual separation from a VFR aircraft operating in the control zone after the required coordination with the airport controller has been completed.

C. the aircraft reports sighting:1. the airport if there is no preceding IFR or CVFR traffic; or

566.1 C. 1. Phraseology:CLEARED TO THE (name) AIRPORT, VISUAL APPROACH.— or —CLEARED TO THE (name) AIRPORT, VISUAL APPROACH (runway). FOLLOW (traffic).

2. the aircraft it will be instructed to follow.566.1 C. 2. Note 1: The aircraft being cleared for the visual approach may be sequenced to land after an aircraft which is approaching to land on a different runway.566.1 C. 2. Note 2: The aircraft cleared for the visual approach may decrease speed to avoid anticipated wake turbulence vortices if following heavier category aircraft.566.1 C. 2. Note 3: At uncontrolled airports, controllers may not be aware of the VFR traffic, therefore, it is the pilot's responsibility to conduct the visual approach without the benefit of receiving VFR traffic information.

D. you ensure the aircraft will complete its approach by following a flight path which will not compromise separation with other IFR or CVFR aircraft.

566.1 D. Note: Separation is maintained through monitoring the progress of the aircraft after it is cleared for a visual approach.

E. in multiple traffic situations, you ensure that there is no mistaken identification by having the pilot confirm the type and position of the aircraft to be followed.

566.1 E. Phraseology:(Aircraft identification) NUMBER 1 FOR RUNWAY (number) NUMBER 2 FOR LANDING. TRAFFIC (type and location) LANDING RUNWAY (number of other runway).566.1 E. Note: You ensure the pilot has sighted the correct aircraft to follow by having the type and position of the aircraft verified, if traffic conditions are such that the possibility of misidentification exists.

566.2Inform the airport controller/FSS of the position of an aircraft cleared for a visual approach relative to:A. the airport;B. any traffic the aircraft will be following; orC. any traffic from which the aircraft will be maintaining visual separation.

567 VISUAL APPROACHES TO MULTIPLE RUNWAYS

567.1Inform all aircraft when conducting visual approaches to multiple runways.

567.1 Note: ATIS may be used to inform aircraft that visual approaches are being conducted simultaneously to more than one runway.

567.2Maintain IFR separation until visual separation is applied when conducting visual approaches to multiple runways.

567.3In addition to the requirements in 566.1 A. through D., apply the following conditions when conducting visual approaches to parallel, intersecting and converging runways:A. parallel runways separated by less than 2,500 feet;

1. maintain IFR separation until the aircraft reports sighting any preceding aircraft on final approach to the adjacent runway;2. instruct the aircraft to maintain visual separation from the reported traffic;3. do not permit a heavy aircraft to pass any other aircraft or a medium aircraft to pass a light aircraft.

B. parallel runways separated by 2,500 but less than 4,300 feet and both aircraft are being vectored for visual approaches;

1. maintain other than visual separation until the aircraft are established on a heading which will intercept the extended runway centreline by 30 degrees or less; and

ATC 205

567.3 B. 1. Note: The intent of the 30 degree intercept angle is to reduce the requirement for steep turns which may prevent the sighting of aircraft operating on closely spaced parallel tracks.

2. both aircraft have received and acknowledged the visual approach clearance.C. parallel runways separated 4,300 feet or more and both aircraft are being vectored for visual approaches, maintain other than visual separation until one of the aircraft has received and acknowledged the visual approach clearance;D. if one of the aircraft in 567.3 A., B. or C. is being vectored for a visual approach while another is being vectored for an instrument approach, maintain separation other than visual separation until the aircraft conducting the visual approach has received and acknowledged the visual approach clearance;

567.3 D. Note: If runways are separated by 2,500 but less than 4,300 feet, both aircraft are to be on a heading which will intercept the extended runway centreline by 30 degrees or less.

E. intersecting and converging runways:1. maintain IFR separation until the aircraft has received and acknowledged the visual approach clearance.2. visual approaches may be conducted simultaneously with visual or instrument approaches to another runway.

567.3 E. 2. Phraseology:(Aircraft identification) NUMBER 1 FOR RUNWAY (number) NUMBER 2 FOR LANDING. TRAFFIC (type and location) LANDING RUNWAY (number of other runway).567.3 E. 2. Note: The aircraft being cleared for the visual approach may be sequenced to land after an aircraft which is approaching to land on a different runway.

568 PUBLISHED VISUAL APPROACH PROCEDURES

568.1Clear an aircraft for a published visual approach to a controlled airport provided:

568.1 Note: In order to clear aircraft for a published visual approach, the procedure must be published in the local AIP.

A. The approach is conducted in a radar environment.B. The published name of the approach and the landing runway are specified in the approach clearance.C. The reported ceiling is 500 feet above the MVA and the ground visibility is 3 miles or more.D. The aircraft reports sighting a published visual landmark or reports sighting a preceding aircraft on the same approach and has been instructed to follow that aircraft.E. When using parallel, intersecting or converging runways the conditions specified in 567 must also be met.

569 RNAV STAR PROCEDURES

569.1Allow aircraft operating on an RNAV STAR to conduct their own navigation to the extent possible. 569.1 Note: Assignment of radar vectors to an aircraft conducting an RNAV STAR will cancel the STAR. Once the traffic situation is resolved, the controllermay re-clear the aircraft to fly the RNAV STAR via/ direct any waypoint contained within the STAR.

569.2Consider an aircraft to have been cleared for the RNAV STAR provided the STAR is included in the routing portion of the flight plan.

569.2 Note: There is no requirement to re-clear an aircraft for an RNAV STAR if there are no published altitude restrictions, (excluding the altitudes published at the DTW or FACF).

569.3When issuing approach clearance to an aircraft flying an open RNAV STAR, issue the clearance no later than 3 miles from the DTW. If unable, provide radar vectors to the aircraft.

569.3 Note 1: 3 miles allows sufficient time for the pilot to connect the RNAV STAR to the IFR approach.569.3 Note 2: If approach clearance is:A. not received by the DTW, the aircraft will maintain the published heading depicted on the chart and expect radar vectors; orB. received, the aircraft will follow the RNAV route to the DTW, hence to the FACF and conduct a straight-in approach.569.3 Note 3: Clearance for a visual approach automatically cancels the RNAV STAR.569.3 Note 4: The phrase “straight-in” may be omitted, as it is part of the RNAV procedure.569.3 Diagram:

ATC 206

569.4Clear an aircraft flying an RNAV STAR for descent in sufficient time to be at the published minimum altitude, prior to crossing the Final Approach Course Fix (FACF).

569.4 Note: The published altitude at the FACF allows the aircraft to intercept the glide path from below.

569.5Do not clear an aircraft flying an RNAV STAR, to an altitude below the FACF altitude.

569.5 Note: The published altitude at the FACF meets noise abatement requirements and is the lowest altitude contained in the RNAV STAR.

569.6Clear an aircraft flying an RNAV STAR, to fly direct to any waypoint, contained within the STAR, if:A. you will gain an operational advantage, orB. the aircraft requests it and traffic conditions permit. (P)(D)

571.1 A. 1. Note: ATIS may be used.2. vectors each aircraft:

a. to provide a minimum of 1 mile of straight and level flight prior to final approach course interception; and

571.1 A. 2. a. Note: The purpose of providing 1 mile of straight and level flight prior to final approach course interception is to dissipate speed and to prevent overshooting the final approach course.

b. to intercept the final approach course, at an angle of 30 degrees or less, and at a point 2 miles or more from where final descent will begin:

571.1 A. 2. b. Note: The provisions of 564.2 do not apply when simultaneous independent parallel approaches are being conducted.

3. informs each aircraft of the runway number upon initial contact.4. provides a minimum of 1,000 feet vertical or 3 miles radar separation until both aircraft are within their normal operating zones and established on their respective localizers.

571.1 A. 4. Note 1: The “Normal Operating Zone” (NOZ) is that airspace each side of the runway centreline, within which, aircraft are expected to remain while conducting normal manoeuvring.571.1 A. 4. Note 2: Where runways are separated by more than 5,000 feet that part of the “Normal Operating Zone” that is immediately adjacent to the “No Transgression Zone” (NTZ) should be depicted on the radar map.

5. applies appropriate separation from other IFR or CVFR aircraft except for aircraft established on the parallel localizer and within the NOZ for the parallel runway.

571.1 A. 5. Note: Aircraft established on a final approach course are considered separated from aircraft established on an adjacent final approach course provided it is apparent that neither aircraft is on a track that will cause it to penetrate the NTZ.

6. instructs aircraft to maintain an altitude until established on the localizer being used; 571.1 A. 6. Phraseology:(number) MILES FROM (fix) or (number) MILES FROM THE THRESHOLD.

571.1 A. 7. Note 1: Frequency change will normally be completed 2 miles before glide path interception.571.1 A. 7. Note 2: At some units, the mode of operation may require that the monitor controller have a dedicated frequency rather than override capability on the airport control frequencies. In such cases, frequency changes should be in accordance with unit directives.

8. considers known factors that may, in any way, affect the safety of simultaneous independent approaches.

571.1 A. 8. Note: Wind shear and changing wind conditions in the final approach area may cause aircraft to deviate from centreline of the approach.

B. the Monitor Controller (the Monitor Controller and Arrival Controller would be the same unless otherwise instructed);

1. monitors all simultaneous independent approaches;2. maintains a listening watch on the appropriate airport control frequencies.3. considers the aircraft to be the centre of the PPS;

571.1 B. 3. Note: In lieu of the monitor controller maintaining a listening watch on the airport control frequencies the aircraft may be changed to a dedicated monitor control frequency, while they are in the NOZ, provided it is in accordance with unit directives.

4. issues necessary instructions and information, on the appropriate airport control or dedicated frequency, so as to ensure that aircraft remain within the applicable NOZ as follows:

571.1 B. 4. Note: The “No Transgression Zone” is to be depicted on the radar display used by the monitor controller.

610 COMMUNICATION FAILURE

611 GENERAL

611.1If you are unable to maintain two-way radio communication with an IFR aircraft operating in or about to enter controlled airspace, take the following actions: A. Separate other aircraft from the aircraft having the communication failure, based on the assumption that it will follow the rules and procedures in the Local Regulations, the Local Rules of the Air (annex II) or the Local AIP unless you determine that:

1. based on electronic or other aids, a different action can be taken without impairing safety; 2. the aircraft is not following the rules specified in the Local Regulations and the procedures described in the Local Rules of the Air (annex II); or3. the aircraft has landed.

B. Make a blind transmission of the following information:1. Description of the action taken by ATC.2. Weather conditions at destination and alternate airports.

C. Give pertinent traffic information to other aircraft in the vicinity of the aircraft experiencing the communication failure.D. As appropriate:

1. inform the alternate airport, adjacent ATC units, and all appropriate communication, VDF, and radar stations of the details of the failure;2. request all units and stations to attempt to contact the aircraft; and3. request all VDF and radar stations to attempt to locate and identify the aircraft.

E. To reduce the possibility of confliction with an aircraft experiencing a communication failure, suspend or restrict, to the extent necessary, the movement of other aircraft in the vicinity of the destination airport for 30 minutes after the latest of the following times:

1. The estimated time of arrival furnished by the aircraft.2. The estimated time of arrival calculated by the IFR unit.3. The estimated time en route included in the flight plan.4. The expect-approach-clearance time last acknowledged by the aircraft.5. If an approach clearance has been acknowledged, the time at which the aircraft is known or estimated to have commenced the approach.

F. If the aircraft has not reported within the 30 minute period specified in 611.1 E.:1. forward pertinent information concerning the aircraft to all aircraft operators and the pilots of aircraft concerned; and

611.1 F. 1. Note: You are expected not to reveal the identification or ownership of the unreported aircraft unless necessary.

2. resume normal operations if they so desire. 611.1 F. 2. Note: It is the responsibility of the aircraft operators and pilots to determine whether they will resume normal operations.

G. Inform appropriate units and stations if communication is re-established or the aircraft lands.

612 COMMUNICATION FAILURE UNDER RADAR CONTROL

612.1If you are unable to maintain two-way radio communication with a radar-controlled aircraft, transmit, on appropriate frequencies, a request that the aircraft acknowledge transmissions by:

612.1 Phraseology:IF YOU READ, (appropriate instructions). then — (Action) OBSERVED, WILL CONTINUE RADAR CONTROL.

A. squawking “ident”;B. changing SSR code;C. squawking “standby” for a specified period of time and then squawking an appropriate code; or

612.1 C. Note: The period of time specified must be sufficient to assure that the loss of target resulted from squawking standby.

D. executing a specified turn.

612.2If communication is re-established in this manner, request the aircraft to acknowledge clearances or instructions or to answer questions by using the transponder or executing turns.

ATC 216

612.2 Phraseology:(Clearance/instruction). ACKNOWLEDGE BY (action).(Question). IF AFFIRMATIVE/NEGATIVE, (action).

612.3Separate other aircraft from a radar-controlled aircraft that has a communication failure based on:A. its course of action as observed on radar; and

612.3 A. Note: If communication is lost with an aircraft being vectored, the pilot is expected to proceed by the most direct route practicable to the NAVAID, or route specified in the last clearance.

B. the assumption that it will maintain altitudes in accordance with the Canadian Aviation Regulations and the procedures described in the Local Regulations, the Local Rules of the Air (annex II) or the Local AIP.

612.3 B. Note: If a communication failure occurs while an aircraft is being vectored at an altitude below the published minimum IFR altitude, the pilot is expected to climb immediately to the appropriate published minimum IFR altitude, unless able to continue in VMC.

612.4Allow for the possibility that an aircraft may not be able to use the approach aid specified, if communication is lost while it is being vectored for an approach.

703.1 A. 2. Note: Formation leaders are required to inform ATC of the dimensions of a formation when flying a nonstandard formation.703.1 A. 2. Example: Formation operating on a frontal width of more than 1 mile: lateral separation is increased by an equal amount. Formation operating with more than 1 mile longitudinally between first and last aircraft: longitudinal separation is increased accordingly.

B. Radar:1. for a standard formation flight, add one mile to the appropriate radar separation minima;2. between two standard formation flights, add two miles to the appropriate radar separation minima;3. for a non-standard formation flight, apply the appropriate radar separation minima to the perimeter of the airspace encompassing the non-standard formation or from the outermost aircraft of the non-standard formation, whichever applies; and4. if necessary, assign an appropriate transponder code to each aircraft in the formation, or to the first and last aircraft in trail.

703.2Control formation flights as a single aircraft, and issue control instructions to the formation leader. When individual control is requested, issue advisory information which will assist the aircraft in attaining separation between the formation and the aircraft to be provided individual control.

703.2 Note 1: Although civil IFR formation flights are to plan a formation takeoff and landing, unforeseen conditions may preclude a formation landing.

ATC 233

703.2 Note 2: The formation leader shall be responsible for the separation between all sections or individual aircraft until:A. position reports indicate that minimum IFR separation has been achieved; orB. they are observed on radar and the minimum radar separation has been achieved.

750 MINIMUM NAVIGATION PERFORMANCE SPECIFICATIONS (MNPS) CONTROL PROCEDURES

751 APPLICATION

751.1The control procedures may be applied to MNPS certified aircraft operating within MNPS airspace and the MNPS transition area.

751.2You may authorize non-certified aircraft to operate within MNPS airspace provided:A. an altitude reservation has been approved;B. there will be no penalty to MNPS certified aircraft; orC. the aircraft declares an emergency.

751.3Do not provide a non-certified aircraft with the reduced separation criteria that apply only to certified aircraft.

752 MNPS TRACKS

752.1You may reroute aircraft operating on random tracks to establish MNPS tracks if traffic warrants.

753 SEPARATION

753.1Separate MNPS certified aircraft using area navigation systems and operating off airways as follows:

753.1 Note: If applicable, separation minima in Part 4 may be used in conjunction with these procedures.A. Base control on projected tracks andestimates as substantiated by position reports.

753.1 A. Note: Position reports derived from on board navigation systems of MNPS aircraft may be used for control purposes.

B. Separate aircraft based on the minima and procedures specified in this section. 753.1 B. Note 1: Vertical separation may be established or discontinued where the aircraft crosses the nearest full or half degree of latitude or longitude that will provide the required separation.753.1 B. Note 2: Lateral separation exists until the time that an aircraft on one track reaches a point:A. 60 miles, as measured perpendicularly, to the other track; orB. determined by latitude or longitude as follows:

1. 1 degree of latitude; or2. the required degrees of longitude that provide at least 60 miles between tracks.

753.1 B. Note 3: In the case of intersecting tracks, determination of the point where 60 miles exists between centrelines may be based upon the point where protected airspace overlaps, versus measuring 60 miles perpendicularly from the other track. RNAV distances may be used in applying vertical separation to identify the point where protected airspace overlap, by using the information in 753.1 B. Note 4 and 754.5 Note.753.1 B. Note 4: The following table may be used to determine the distance where vertical separation must be established, measured from the point where tracks cross.

757 LONGITUDINAL SEPARATION — MACH-NUMBER TECHNIQUE

757.1Apply Mach-number technique if required for separation of aircraft entering MNPS airspace.

757.1 Note 1: When reclearing aircraft on initial entry into Domestic airspace and separation is based on Mach-number technique, it is necessary that the Mach-number form part of the clearance.757.1 Note 2: Once accepted as part of the ATC clearance the Mach-number will be adhered to, unless the aircraft obtains ATC approval to change.

757.2When applying Mach-number technique, assign a Mach-number in each clearance issued for the duration of the application.

757.3Ensure that the required separation is being maintained or increased while applying Machnumber technique, by obtaining:A. position reports at significant points that are not more than one hour's flying time apart; andB. as necessary, confirmation from the pilot that the assigned Mach-number is being maintained.

757.3 B. Phraseology:CONFIRM MAINTAINING MACH (number).757.3 B. Note: Requests for confirmation of Mach-number may be done in conjunction with a position report.

757.4Separate aircraft by 10 minutes provided:

757.4 Diagram:

A. the Mach-number technique is used;B. the aircraft are in level flight, climbing, or descending;C. the aircraft are operating on the identical track or continuously diverging tracks;D. the aircraft have reported over a common point; andE. the required longitudinal separation will be maintained until tracks diverge, and when tracks diverge, the required lateral separation and at least 5 minutes longitudinal separation will exist at the point where lateral separation is achieved. 757.4 E.

757.5 Note 1: Where automated systems provide conflict prediction, there is no requirement to use the diagram to determine the appropriate separation minimum.757.5 Note 2: Groundspeed determined from RNAV position reports or radar displayed information is acceptable.757.5 Note 3: The following table may be used as a rule of thumb to determine the required separation:A. until tracks diverge, and when tracks diverge, the required lateral separation and at least 5 minutes longitudinal separation will exist at the point where lateral separation is achieved; or B. to a point at which another form of separation will be achieved.

ATC 250

757.6You may separate aircraft that have not reported over a common point as specified in 757.4, provided you ensure through the use of radar, DME, or RNAV distance, that the minimum will exist at the common point from which the aircraft will follow an identical track or continuously diverging tracks.

757.6 Diagram:

757.7You may reduce the minimum specified in 757.4 in accordance with the following table, provided:

757.7 Note: If the aircraft will follow continuously diverging tracks and the required lateral separation will be achieved not later than 20 minutes after the preceding aircraft has passed the common point, the requirement to have 5 minutes longitudinal separation where lateral separation is achieved does not apply.

A. the preceding aircraft is maintaining a greater Mach-number than the succeeding aircraft; andB.

ATC 251

1. the aircraft have reported over a common point; or 757.7 B. 1. Note: The fix tolerance area for the fix derived from ground based NAVAIDs shall not exceed that of an NDB at the appropriate altitude.

2. radar, DME, or RNAV distance is used to ensure that the appropriate time interval exists and will exist at the common point.

901 RECOMMENDED COMPLETION OF IFR STRIPS

901.1Since IVAC is using Electronic Flight Strips the only editable fields apart from the E-FPL itself, are WP and CL fields.

Note 901.1: WP corresponds to the field used for clearances affecting lateral navigation and CL for clearances affecting vertical navigation.

901.2It is recommended to use the WP and CL fields as follows:

Note 901.2: Division or local procedures may differ.A. for lateral navigation WP field would be used and it is expected to be filled with a maximum of 3 characters; except for:

Example 901.2.AIf a traffic is cleared direct to XEBAR fix, XEB should be inserted in the field WP. Diagram 901.2.A

1. When using a published procedure which is being differentiated through a designator code.Example 901.2.A.1A traffic is cleared for AMTOS3C arrival, AMT3C should be inserted in the field WP

2.When using the ICAO code for the destination airport, where only the last two letters would be used.Example 901.2.A.2A traffic is following his flight plan as filled, final destination is LFPG, PG would be inserted in the WP field since LF letters are redundant.

3. When using codes related to special situations or approach procedures.Example 1 901.2.A.3A traffic requests vectors for app, ATC would insert REQVCT to point out this special situation to fellow ATC.Example 2 901.2.A.3A traffic is cleared for an ILS approach for runway 30L, then I30L would be inserted.

B. for vertical navigation, CL field would be used and it is expected to be filled with the flight level or altitude cleared for the flight.

901.3The WP field should show the last two letter of the ICAO airport code unless:A. otherwise instructed by local proceduresB. the destination airport is beyond limits

Note 901.3.B: When the destination airport is out of the ATC responsabilities, then the first 3 letters of the FIX or NAVAID where the flight will abandon the airspace should be inserted.

C. Any other relevant clearance affects the flight
