RUNWAY REQUIRMENTS (R A T P A W T T)
AFI 11-2T-1v3 3.3.3.1
Takeoff: the minimum runway length for T-1A takeoffs is 6,000 ft, critical field length (CFL), or the distance
required to reach reference zero (takeoff ground run + takeoff flare distance), whichever is greater.
Note the minimum useable runway is computed between arresting cables located on or above therunway surface
Landing: the minimum runway length for full stop landings is 6,000 feet or computed landing distance,
whichever is greater If the tabular data landing distance is within 1,000 ft of the total useable runway for landing, aircrews
must use the longer of the performance chart or tabular data landing distance
Touch and Go: the minimum useable runway length for touch and go landings must be equal to or greater
than the applicable touch and go distance but never less than 6,000 feet
Touch and go distances reflect the most restrictive of the go or stop option from the appropriate decisionpoint (T/F)
The applicable touch and go distance allows acceleration, rotation, and climb to reference zero bydeparture end, or deceleration to stop within the runway remaining
Width: minimum width is 100 feet
RCR: minimum RCR for all operations must be 12 or greater
APPROACH REQUIRMENTS (destination requirements for filing purposes) (RA T P A W T T)
11-202v3 ch 8
Destination with a published radar approach (ASR/PAR):
For pilots to fly a published radar approach or instrument approach procedure that requires radar todefine a fix (RADAR REQUIRED on an approach plate) essential for flying the approach, a non radar
facility (VORTAC, TACAN, etc.) must provide a positive aircraft position within 25 NMs of the airfield

Pilots operating in Class A airspace may file to the nearest non radar facility or fix (regardless of distancefrom the terminal) and request radar vector service to the terminal
Identifying the MAP 11-217v1 12.2.1.7.1
The middle marker may never be used as the sole means of identifying the MAP. If the middle marker isthe only way to identify the MAP (e.g. no timing published and DME out of service), then the approach is
not authorized

Weather for the ETA ( 1 hour) at destination or recovery base must be at or above the lowestcompatible published landing minimums, or suitable PWC, for the aircraft concerned, whichever is
greater
For a straight in or sidestep approach, the forecast weather must meet only the published visibilityrequirements of that approach
For a circling approach, the forecast weather must meet both the ceiling and prevailing visibilityrequirements
Night11-2T1v3 3.6.3, 3.6.4
Filing
Do not file to a destination other than your home field unless there is an operable straight in approachwith glide path guidance
Aircrews may perform en route descents at facilities with no glide path guidance if they descend nolower than the published MDA
PAPIs, VASIs, precision guidance systems, or GPS vertical navigation constitute acceptable guidance Do not file to a destination at night if a circling approach is the only available approach For night IFR operations, alternates must have an operational instrument straight in approachNight VFR patterns
Ceiling and visibility must be 2,000/3 or circling minimums, whichever is higher Must be a familiar field Visual and/or instrument glide path (including GPS vertical navigation) guidance must be available and
used by the aircrew for all off station night landings
Turbulence 11-2T-1v3 3.8.1.1
The T-1A will not be flown in areas of forecasted or reported severe turbulence, severe icing, freezingrain, or freezing drizzle. If severe icing or turbulence is encountered on a mission, but was not forecast,
ensure appropriate weather personnel are notified as soon as possible
LAFBI 11-201v4 1.5.5.1.2
Discontinue all mountainous low level operations in actual moderate turbulence or if moderateturbulence has been reported in the previous 2 hours
Wake turbulence 11-202v3 5.26.4.1
Notify ATC when encountering wake turbulence on any approachTurbulence penetration T.O. 1T-1A-1 7-3
Turbulence penetration speed is 200 KIAS or 0.58 Mach, whichever is lower Do not chase airspeed or altitude TAF turbulence decoding ex 520004 (see FIH sec C)
Turbulence designator is 5 (520004) Next digit is the intensity (520004) Next three digits is the base in hundreds of feet (520004) Last digit is the thickness in thousands of feet, add to base to get layer top (520004)
Thunderstorms 11-2T-1v3 LAFB Sup
Aircrews will avoid thunderstorms by at least 10 NM below FL 230 and at least 20 NM at or above FL 230 Aircrews should not plan to depart, or conduct flight operations, when thunderstorms are within 10 NM
of LAFB
At out base locations, when thunderstorms are between 5-10 NM, crews must ensure departure planningallows for an immediate turn (400 AGL minimum) to begin a turn away from the thunderstorm
If any adverse affects of the storm have reached the field (gust front winds, heavy rain, etc.) do not takeoff
Operations into thunderstorms 11-202v3 5.26
7/30/2019 Navigation Study Guide
6/33
Page 6 of33
Operations in the vicinity of hazards unless MAJCOM approved, USAF aircraft will not be operated inany forecast or actual severe condition (i.e. severe icing, turbulence, actual bird watch condition severe,
etc.)
The PIC shallot intentionally operate into a thunderstorm except when operating on a MAJCOM approvedmission specifically requiring thunderstorm penetration
Pilots shall not fly in IMC in the vicinity of actual thunderstorms without operable radar, unlessspecifically approved by MAJCOM
Pilots will not takeoff, land, or fly an approach at an airport where thunderstorms are producing hail,strong winds, gust fronts, heavy rain, lightning, windshear, or microbursts
Flight planned route - when forecast, observed, or reported hazardous weather activity (thunderstorm orother severe weather condition) affects the planned route, pilots will alter the route of flight to avoid the
hazard, delay the scheduled mission, or proceed to a suitable alternate
Thunderstorm penetration
Target penetration speed of 200 KIAS or 0.58 Mach, whichever is lower Trim for a known condition and do not chase the performance instrumentsAdditional Thunderstorm Guidance (47 OGV FAQ from AETC A3FV, AFFSA)
AETC pilots are to take the reasonable man approach to thunderstorm or other severe weatherconditions. Thunderstorms or other severe weather conditions are not the possibility of pop up
thunderstorms that we experience in the summer. Thunderstorms associated with frontal passage or
other forecast phenomena are grounds for re-routing
The key words in the 11-202v3 are affect the route of flight and to avoid the hazard. A general forecastfor thunderstorms after 14Z in western Texas does not affect route of flight yet.
Lightning
Lightning strikes are most likely to occur within 5,000 ft and 8 C of the freezing levelLocal lightning procedures
Lightning watch A lightning watch is in effect 30 minutes prior to a thunderstorm within 5 NM of the airfield Aircrew and maintenance personnel may continue normal activities
Lightning warning Lightning has been observed within 5 NM of LAFB Take immediate shelter When a warning is declared while performing a walk around, take shelter If a warning is declared after engine start but before taxi, shut down and take shelter If a warning is declared while taxiing, taxi back to the appropriate row, but do not taxi into a parking
spot. Wait in the jet until it is safe for maintenance personnel to return. Aircrew may shut down due
to fuel constraints. Remain in the aircraft until ground personnel are available to pin the gear and
chock the aircraft
Wind and Windshear
Wind 11-2T-1v3 LAFB Sup
Aircrews should not plan to stop at airfields where the winds, forecast or actual, steady state or gusts,exceed 35 knots
Aircrews should not conduct ground operations or touch and gos when winds, steady state or gusts,exceed 35 knots
Squadron SUP approval is required to continue operations with reported steady state winds above 35knots
Windshear T.O. 1T-1A-1 7-4
Windshear Defined
7/30/2019 Navigation Study Guide
7/33
Page 7 of33
Windshear is a change of wind speed and or direction over a short distance along the flight path. Severe windshear is that which produces airspeed changes greater than 15 kts or vertical speed
changes greater than 500/min
Windshear takeoff procedures Use the longest suitable runway
Use 10 flaps Increase rotation speed up to 10 kts (if performance data allows) Do not reset the airspeed bugs Do not decrease pitch below normal after liftoff in attempt to increase airspeed at low altitude
Reference groundspeed Defined
Reference groundspeed is the expected groundspeed on final at approach speed in a no shearcondition
Computed by subtracting the surface headwind component (adding tailwind component) fromapproach true airspeed
Loss shear
If actual groundspeed is less than reference groundspeed, you can expect a decreasing headwindcondition or loss of shear during the approach
Reference groundspeed actual groundspeed = X. fly approach speed + X Gain shear
If actual groundspeed exceeds reference groundspeed, you can expect a decreasing tailwindcondition or gain shear during the approach
Actual groundspeed reference groundspeed = X Fly approach speed and monitor actual groundspeed. If shear is abrupt, airspeed will increase by X
Windshear approach procedures A difference of 15 kts or more indicates the presence of significant wind shear Use the longest suitable runway that avoids suspected areas of wind shear
Compute reference groundspeed Compare actual groundspeed with reference groundspeed no later than the FAF. Apply the
correction
Select 10 flap approach and lading if stopping distance is not critical. Use the autopilot and flightdirector
Stabilize the approach no later than 1,000 ft AGL. If not stabilized prior to 1,000 ft AGL, abort theapproach
Pause to evaluate for airspeed trends before compensating for airspeed changes. Aovid large thrustreductions or trim changes in response to sudden airspeed increases
Immediately initiate wind shear recovery procedures if a sever wind shear condition is encountered Windshear recovery procedures
Immediately apply full power Do not hesitate to firewall the throttles in lieu of ground impact
Rotate toward 15 pitch attitude at a normal pitch rate Increase AoA to in and out of the stick shaker If at 30 flaps, select 10 flaps Do not raise the landing gear until continued flight without ground contact is assured Once the aircraft is climbing and ground contact is no longer an immediate concern, airspeed should
be increased by cautious reductions in pitch attitude

Reestablish appropriate trust setting when stable performance is achieved Reporting windshear 11-202v3 5.26.4.2
Immediately report a windshear or microburst encounter on takeoff, approach, or landing to themost appropriate agency and if possible, include: the altitude, loss or gain in airspeed or altitude, the
type of aircraft and the location of occurrence
Icing
Freezing precipitation (ice / snow / frost) 11-202v3 5.26 Pilots will not takeoff with ice, snow, frost, or other contamination adhering to the wings, control
surfaces, propellers, engine inlets, or other critical surfaces of the aircraft, unless authorized by the
program manager or flight manual
A thin coating of frost is permitted on the fuselage, provided the lettering and/or paint lines arevisible
Light frost (up to 1/8 inch thick) caused by super cooled fuel is permitted on the lower wing surface(i.e. below the fuel tank area) if the fuselage and all other control surfaces are free of all icing. If
deicing is required on any other aircraft surface, the underwing frost shall also be removed
Ice and/or snow conditions 11-2T-1v3 3.2.3, 3.3.3, 3.8.1 Do not taxi during ice or snow conditions until all portions of the taxi route and runway have been
checked for safe conditions
When ice and / or snow are present on the taxiway, taxi on the centerline with a minimum of 300ft spacing
Takeoffs and touch and go landings will not be accomplished on unplowed runways when ice orsnow is present
These operations are permitted on plowed runways provided the plowed portion is a minimum of100 ft wide and meets the minimum length requirements
Additionally, the RCR of the paved surface must be 12 or greater The T-1A will not be flown in areas of forecast or known severe turbulence. In addition, it will not be
flown in areas of forecasted or reported severe icing or in freezing rain or drizzle. If severe icing or
turbulence is encountered on a mission, but was not forecast, ensure appropriate weather personnel
are notified as soon as possible. Do not cruise or conduct multiple pattern operations in actual
moderate icing conditions
Local icing guidance, 86th SOP, 11-2T1v3 LAFB Sup Anti ice equipment will be turned on at temperatures of 5C RAT or less when in visible moisture.
These systems should be turned on prior to encountering actual icing to allow preheating of aircraft
surfaces
When conducting touch and go(s) in conditions that require the use of anti ice equipment, a 1,000 ftceiling is required for touch and go landings. The anti ice will be off during the actual touch and go
Takeoff with ice or frost 11-202v3 5.26.6 Pilots will not takeoff with ice, snow, frost, or other contamination adhering to the wings, control
surfaces, propellers, engine inlets, or other critical surfaces of the aircraft, unless authorized by the
program manager or flight manual
A thin coating of frost is permitted on the fuselage, provided the lettering and/or paint lines arevisible
Light frost (up to 1/8th inch thick) caused by super cooled fuel is permitted on the lower wing surface(i.e. below the fuel tank area) if the fuselage and all other control surfaces are free of all icing. If
deicing is requir3ed on any other aircraft surface, the under wing frost shall also be removed

ODP (traditional ) RTRL (type of ODP) VCOA (type of ODP) SD ODP (type of ODP)
SID Specific instructions Diverse
Special MAJCOM ODPs and SIDs should be flown to the maximum extent possible ODPs pilots will fly the published ODP for the runway used
ODP Includes standard routing to fly after takeoff
VCOA Pilots will not fly any VCOA procedure until MAJCOM certified Weather must be at or above the minimums published for the VCOA. Unless published, pilots
will consider the VCOAs visibility requirement as a remain within distance
Reduced Takeoff Runway Length ODP Pilots using a published RTRL procedure shall ensure their aircraft can attain a safe liftoff speed
and rotate prior to the distance remaining specified in the procedure AETC aircrews should contact HQ AETC TERPS for ad hoc RTRL guidance
Sector Departure ODP Pilots may fly sector departure ODPs as published
SID PICs will comply with the routing, altitudes, and climb gradient (including notes) published on the
SID (or if applicable)
Specific ATC departure instructions Refer to specific navigational guidance issued with the clearance or by tower If the departure has any published climb gradients, the PIC must meet or exceed the highest gradient
when departing via ATC instructions. If unable, coordinate with ATC
Pilots are never relieved ofthe responsibility for terrain and obstacle avoidance. Radar contactonly means the aircraft has been identified on radar. Responsibility is only shared between the pilotand ATC when ATC is providing navigational guidance based on radar
Diverse departures Pilots will track runway centerline to 400 ft above the DER before turning on course Pilots will ensure that they vertically clear all applicable low close in obstacles published in NOTAMS
or in the
7/30/2019 Navigation Study Guide
10/33
Page 10 of33
Diverse departures are not authorized when an obstacle departure procedure, climb gradient or nonstandard takeoff weather minima are published for that runway
Special MAJCOM certification MAJCOMs may develop departure procedures for their aircraft at specific locations that allow safe
aircraft departure
IFR Departure Procedures 11-217v1 Ch7
IFR departure philosophy TERPS starts with a standard climb rate of 200 ft/nm, normally beginning at the end of the runway If a gradient other than standard is required, it will be published In civil aviation, pilots may takeoff in good or marginal weather as long as they can see and avoid
obstacles and terrain
USAF pilots departing IFR may not plan to use see and avoid in lieu of complying with published orstandard climb gradients since AF aircraft are issued their own weather minima
Pilots of USAF aircraft will not use FAA or civil takeoff weather minima nor fly see and avoid inlieu of IFR climb gradients unless specifically authorized by the MAJCOM
USAF aircraft must compute obstacle climb gradients assuming the loss of thrust equal to one engineinoperative
Runway end crossing height 11-217v3 7.3.3 The OCS at USAF and USN bases normally begins at zero feet AGL at the DER At non joint use USAF or USN bases, assume a zero foot runway end crossing height unless a higher
altitude is published
Civil/ICAO/NATO bases if the screen height is not published in the ODP or other reliable source,pilots will plan to cross the DER at or above 35 ft
ODPs Notification of their existence Low close in obstacles
Obstacles that would generate an excessive climb gradient (>200 ft/nm) that terminates at orbelow 200 ft above the DER
Pilots will calculate their aircraft performance to ensure they can vertically clear applicable lowclose in obstacles on all departures
Non standard takeoff minima USAF aircraft are not authorized to flight plan using see and avoid in lieu of meeting standard or
published climb gradients
Pilots may only use non standard weather minima for takeoff if aircraft performance will allowthe aircraft to climb to the non standard ceiling requirement by the DER and comply with
published (or standard if none published) climb gradient requirements thereafter to an
appropriate IFR altitude
Types of non standard wx minima Aircraft category Minimum climb gradient Minimum climb gradient in lieu of non-standard wx Specific routing you must be careful when using this type of IFR ODP as a requirement may
exist to use non standard takeoff weather minima in order to execute the procedure
Combination ODP VCOA
7/30/2019 Navigation Study Guide
11/33
Page 11 of33
A VCOA is an ODP that requires a climb in visual conditions over the airfield or an on airportnavaid to an altitude where the aircraft enters the standard obstacle protection area of the ODP
A VCOA procedure is indicated by the words climb in visualconditions directly associated witha ceiling and visibility in the takeoff minima section of the ODP and either by a specific VCOA
listing or climb in visual conditions in the departure procedure section of the ODP
VCOA is constructed assuming an airspeed of 250 KIAS and a bank angle of 23 (recommend 30) USAF pilots must not exceed the published distance (or visibility requirement substituted as a
distance) until above the altitude specified in the procedure)
RTRL Allows the aircraft to takeoff and meet climb gradients by artificially limiting the takeoff length of
the runway
Pilots shall only use an RTRL procedure if it is published as an ODP in FLIP Sector diverse departure
Authorized if departing within their departure sector SID
A SID is a departure procedure in graphic and/or textual form established at certain airports tosimplify clearance delivery procedures and aid in traffic flow
If a higher than standard climb gradient is required, it will be published on the SID Military SIDs obstacle clearance climb rates will be denoted with an asterisk while ATC climb rates
will be denoted with a dagger
Civil SIDs do not depict obstacles graphically but list low, close in obstacles textually. Obstacleclimb gradients may be published directly on the SID, or in case of a , in the ODP procedure
Pilot navigation (NAV) SIDs these SIDs are established for airports when terrain and safety relatedfactors necessitate development. Multiple routings from multiple runways may be depicted on the
same SID.
Vector SIDs established where ATC will provide radar navigational guidance to a filed/assignedroute or to a fix depicted on the SID
Three equipment types Non-RNAV DP uses traditional navaids RNAV DP use GPS Radar DP radar SIDs are established when ATC has a need to vector aircraft on departure to a
particular ATS route, navaid, or fix
If given an amended clearance altitude climb and maintain or maintain you may disregardpreviously issued altitude restrictions on the SID. Routing is still in effect
If vectored off the SID routing with no instructions to resume then consider the SID CNX. Specific ATC departure instructions
Include a heading and an altitude When told to fly runway heading, do not apply drift corrections If the departure instructions do not contain a climb gradient and there are not published gradients
for the departure runway, maintain 200 ft/nm.
Diverse departure If no obstacles (other than low close in) penetrate the 40:1 obstacle clearance surface (OCS) for a
particular runway, then a minimum climb gradient of 200 ft/nm will ensure proper obstacle
clearance
If a runway does not have a published DP and does not have an ODP in the IFR takeoff minimums anddeparture procedures specifically stating diverse departure not authorized then diverse departure
is authorized
7/30/2019 Navigation Study Guide
12/33
Page 12 of33
To fly a diverse departure, fly the extended runway centerline ground tack until 400 ft above DERbefore executing any turns. Maintain a climb gradient of 200 ft/nm until reaching a minimum IFR
altitude
Special MAJCOM MAJCOM develops special departure instructions for special aircrew and special aircraft.
Methods to reduce required climb gradients Delay a mission for environmental conditions (temp, pressure, etc.) Delay for mission requirements (fuel, payload, etc.) Reduce the required climb gradient by the ROC safety margin (48 ft option)
RNAV departures Procedure must be retrieved in its entirety Must double check all waypoint names, types, altitudes, and airspeed. May not alter. Need RAIM, must be set to terminal sensitivity Monitor ground based navaids that are part of the basic procedure as required by aircraft specific
flight manuals
Maximum allowable difference between the database course and the published course is 5 anddistances must be within 0.1 nm
No authorized IFR Departure Method 11-202v3 8.12.9
If the airport does not have one of the IFR departures mentioned above, then an IFR departure is notauthorized
Refer to 11-202v3 chapter 7 (VFR)Non-standard takeoff minimums 11-202v3
Pilots will not depart an airfield using non-standard takeoff minimums in lieu of meeting the requiredclimb gradient
When non standard takeoff minima are published, with or without a climb gradient, the PIC may nottakeoff under the provisions of IFR established unless:
The departure procedure authorizes standard takeoff minimums with a climb gradient in lieu of thenon standard criteria or:
The aircraft is capable of being at or above the published non standard takeoff minima ceilingrequirement prior to crossing the departure end of the runway (for multi engine must calculate for
OEI) and can continue a climb profile that will vertically clear all obstacles
Basic rules for all IFR Departures
Regardless of the IFR departure method, these following rules apply Delay all turns until at least 400 ft above DER unless otherwise specified Climb at a minimum of 200 ft/nm unless a higher gradient is required
Radar vectors
Pilots are responsible for terrain and obstacle clearance until a radar vector is issued by ATC Expect to maintain a minimum climb gradient of 200 ft/nm unless a higher gradient is published or
directed by ATC

Regardless of the IFR departure method selected, PICs will climb at a minimum of 200 ft/nm unless ahigher gradient is published for the procedure
Non standard takeoff minimums Pilots will not depart an airfield using non-standard takeoff minimums in lieu of meeting the
required climb gradient
When non standard takeoff minima are published, with or without a climb gradient, the PIC may nottakeoff under the provisions of IFR established unless:
The departure procedure authorizes standard takeoff minimums with a climb gradient in lieu ofthe non standard criteria or:
The aircraft is capable of being at or above the published non standard takeoff minima ceilingrequirement prior to crossing the departure end of the runway (for multi engine must calculate
for OEI) and can continue a climb profile that will vertically clear all obstacles
If you are still unable to comply with the required gradient after exhausting the remedies in 11-202v3 ch8, and IFR departure is not authorized.
Multi engine fixed wing aircraft PICs will ensure the aircraft meets or exceeds the published climb gradient for the selected IFR
departure method, with OEI to an appropriate MIA
Minimum IFR Altitude (MIA) 11-202v3 8.13
On airways Fly no lower than the minimum en route altitude (MEA), minimum reception altitude (MRA),
minimum crossing altitude (MCA), or minimum obstacle clearance altitude for the airway (MOCA)
Off airways Fly no lower than the off route obstacle clearance altitude (OROCA) or the off route terrain clearance
altitude (ORTCA)
An altitude that provides at least 1,000 ft of clearance above all obstacles within 5 nm of the course tobe flown (2,000 ft in mountainous)

Prior to Descent or Approach 11-202v3 8.17
Pilots will obtain the latest destination airport conditions prior to beginning descent or commencingapproach
Pilots shall not begin an en route descent, arrival, or published approach if the destinations weatheris below the required approach minimums
Straight in or sidestep approach weather must only be at or above the published visibilityminimums
Circling approach weather must be at or above both the published ceiling and visibility minimums Determining visibility
RVR must be used if available 11-202v3 8.10 If a variable report is given, pilots will apply the lowest reported RVR value If necessary, pilots may convert the reported visibility from one format to another. Pilots will
use the higher of: the next higher value in the conversion chart, or the highest published valuefrom the IAP minima block; do not interpolate
For circling approaches, PV shall be usedPrior to Descent or Approach 11-2T-1v3 3.8.6
Do not begin a penetration, en route descent, or approach unless existing ceiling and visibility meetrequirements (PWC)
7/30/2019 Navigation Study Guide
20/33
Page 20 of33
After commencing a penetration or approach, if weather is reported below the required PWC orpublished minimums (ceiling or visibility), the pilot may continue the approach to the PWC or published
minimums, whichever is higher
Descent Procedures 11-217v1 9.2
Descend at an optimum rate to 1,000 ft above the assigned altitude If at any time you are unable to descend at a rate of at least 500 fpm, advise ATC
Not required when leveling off at 10,000 ft on descent, or 2,500 ft above airport elevation (prior toentering a Class B, C, or D surface area) when required for speed reduction
Before starting descent, review the IAP, recheck the weather (if appropriate), check the heading andattitude systems, and coordinate lost comm Procedures (if required)
After Beginning Descent or Approach 11-202v3 8.17
If a pilot has begun the en route descent, arrival, or published approach (or given radar vectors), andsubsequently determines the weather is below minimums (visibility for straight in approaches or either
ceiling or visibility for circling approaches):
The pilot must not deviate from the last ATC clearance until obtaining a new clearance The pilot may request a clearance to a holding fix or alternate Unless restricted by MAJCOM, continue the approach as published to the MAP and land, if the aircraft
is in a position to make a safe landing and the runway environment is in sight
(AETC) unless specifically prohibited by AFI 11-2 MDS specific guidance, aircrews are authorized tocontinue a published instrument approach when the weather is below minimums
The PIC will ensure the aircraft has sufficient fuel to go missed approach and land at the alternateairfield with required reserves
After Beginning Descent or Approach 11-2T-1v3 3.8.6.1
After commencing a penetration or approach, if weather is reported below the required PWC orpublished minimums (ceiling or visibility, regardless of the approach) the pilot may:
Continue the approach to the PWC or published minimums, whichever is higher PWC II pilots may continue to published minimums which are below PWC minimums if at home
field
The pilot must ensure the aircraft has sufficient fuel to go missed approach and land at thealternate airfield with the required reserves
The pilot may descend below the DH/DA/MDA if the aircraft is in a position to make a normalapproach to the runway of intended landing and the pilot sees the runway environment
PWC and Precision Approaches 11-2T-1v3 3.8.6.3
PWC minimums on a precision approach or GPS approach flown to LNAV/VNAV minimums may requirepilots to execute a missed approach prior to the published DH/DA
In these instances, on reaching PWC minimums and making the decision not to continue the approach,the pilot should start a climb immediately while proceeding to the missed approach point
On reaching the MAP, the pilot should continue with the published missed approach procedureMISSED APPROACH
When to go Missed 11-217v1 14.4.2.1
The pilot shall perform the missed approach when the MAP, DH, or DA is reached and any of thefollowing exist:
The runway environment is not in sight You are unable to make a safe landing You are directed by the controlling agency
Executing the Missed Approach
7/30/2019 Navigation Study Guide
21/33
Page 21 of33
If on arrival at the MAP or DH/DA (or at any time thereafter) the runway environment is not in sightand/or the aircraft is not in a position to execute a safe landing the pilot must immediately execute the
appropriate missed approach procedure, ATC issued climb out instructions, or other ATC clearance
To ensure obstacle/terrain clearance, the missed approach procedure may not be initiated until over theMAP/DH/DA, unless otherwise cleared by ATC
Climbing prior to the MAP/DH/DA is permitted but ATC should be advised as soon as practicalMissed approach Procedures 11-217v1 14.2
The published missed approach procedure provides obstacle clearance only when the missed approach isconducted on the missed approach segment from or above the missed approach point
When the missed approach is initiated prior to the MAP, the pilot shall, unless otherwise cleared by ATC,fly the IAP as specified on the approach plate to the MAP at or above the DA/DH before executing a
turning maneuver
Initiate the missed approach no later than the MAPMissed Approach / Departure (Climbout) Instructions 11-217v1 14.3
Unless otherwise instructed, initiate an immediate climb to the assigned altitude Delay any turns until past the DER, if visible, and 400 ft AGL If the DR is not visible, climb on rwy hdg until 400 ft AGL before beginning your turnCircling Missed Approach Procedures 11-217v1 14.3.2
If upon reaching the MAP and the airport environment is not in sight, execute the climb out instructionsfrom the MAP
If the circling maneuver has begun and the airport environment is visually lost, begin an initial climbingturn toward the landing runway to ensure the aircraft remains in the obstruction clearance area
Fly the missed approach for the approach procedure just flown, not for the runway of intended landingMissed Approach Climb Gradient11-217v1 14.2.6
Unless a higher climb gradient is published or assigned by ATC, a minimum climb gradient of 200 ft/nmOEI must be maintained during the missed approach procedure
RIGHT OF WAY11-202V3 5.7
Each pilot must take whatever action is necessary to avoid collision, regardless of who has the right ofway. The yielding aircraft must not pass over, under, abeam, or ahead of the other aircraft until well clear
(1,000 ft)
Distress Converging the aircraft to the others right has the right of way. Aircraft ofdifferent categories have
the right of way in the following order:
Balloons Gliders Aircraft towing or refueling other aircraft Airships Rotary or fixed wing aircraft
Approaching head on alter course to the right Overtaking aircraft an overtaken aircraft has the right of way. The overtaking aircraft must alter
course to the right
Landing an aircraft established on final approach has the right of way over other aircraft exceptwhen two or more aircraft are approaching to land
In this case, the lower aircraft has the right of wayAIRSPEEDS 11-202v3 5.9

Disaster areas see NOTAMsWho is the Clearance Authority? 11-202v3 4.6
Uncontrolled airspace the PIC is the clearance authority for IFR or VFR flight in uncontrolled airspace Controlled airspace the PIC shall obtain ATC clearance before an IFR departure (or as soon as
practicable after departure, while maintaining VFR, if contact cannot be established on the ground). The
PIC is the clearance authority for VFR flight (if allowed) in controlled airspace
When can you Deviate From an ATC Clearance?
Deviations 11-202v3 1.7 An ATC clearance is not authority to deviate from the 11-202v3. A PIC may only deviate from any
flight rule or ATC clearance to:
Protect life Safety of flight When an in flight emergency requires immediate action
Notification when deviating, notify ATC as soon as possible Post flight actions
PIC will verbally report the incident to a supervisor and commander within 24 hours and make adetailed written record
The unit will keep a copy of that record for a minimum of 1 year ATC clearances and instructions
The PIC will ensure compliance with ATC clearances or instructions unless: An amended clearance is obtained An emergency exists Deviation is required in response to a TCAS RA Deviation is necessary to ensure safety of flight
Can We File VFR on Top?
11-202v3 8.18
Unless otherwise restricted by MAJCOM, PICS may request and fly IFR VFR on top (IAW 11-217v2)when the mission requires such clearances
AETC VFR on top Prohibited unless needed by syllabus guidance
Define and Describe the Obstacle Clearance Surface (OCS) 11-217v1 7.3
Obstacle clearance surface (OCS) TERPS looks for any obstacle that would penetrate a 152 ft/nm slope (2.5% gradient, 40:1) drawn
from the DER (0)

Page 27 of33
1 nm = 6067 ft Required Obstacle Clearance (ROC)
Add required to the OCS which always adds at least 48 ft/nm which results in a minimum climbgradient of 200 ft/nm (3.3% gradient, 30:1)
OCS, ROC, and diverse departures
The TERPS specialist determines if an obstacle penetrates the OCS in the diverse departure obstacleassessment area
25 nm for non-mountainous areas 46 nm for mountainous areas
On all IFR departure procedures, USAF aircraft are required to meet or exceed 200 ft/nm or thepublished climb gradient, whichever is higher, with all engines operating, or with OEI
The OCS at USAF and USN bases normally begins at 0 ft AGL at the DER, but the OCS may be raised asmuch as 35 ft in order to clear obstacles. If the TERPS specialist raises the OCS, it will be published in the
ODP
US Army and FAA have a screen height of 35 ft DER For any departure at other than non-joint use USAF or USN bases, if the screen height is not published in
the ODP or other reliable source, pilots will plan to cross the DER at or above 35 ft
What Defines a Mountainous Area? 11-217v3 2.11

An ATC clearance allows the aircraft to proceed into the controllers airspace. For example, Tone 69,cleared to enter Class B airspace, maintain 4,500.
Two way radio contact means you are talking to ATC but may or may not have been cleared foranything. In order to be in two way radio contact, the controller must refer to the aircraft by its call
sign
Runway Environment
Descent below MDA is not authorized until sufficient visual reference with the runway environment hasbeen established and the aircraft is in a position to execute a safe landing
Runway environment consists of: The approach light system (except that the pilot may not descend below 100 ft above the TDZE using
the approach lights as a reference unless the red termination bars or the red side row bars are also
visible and identifiable)
The threshold, threshold markings, or threshold lights The runway end identifier lights The touchdown zone, touchdown zone markings, or touchdown zone lights The runway or runway markings The runway lights The visual approach slope indicator
Airport Environment
After descending to circling MDA and when the airport environment is in sight, determine if the ceilingand visibility are sufficient for performing the circling maneuver
The airport environment consists of: The runways Runway lights and markings Taxiways Hangars Other buildings associated with the airport
Note on Radar Contact
In plain English, it means the controller sees your aircrafts radar return on his scope and he haspositively identified you. Its also important to understand what radar contact does not mean it does
not mean the controller now has responsibility for your terrain/obstacle clearance. Specifically, heres
what the AIM says: The term radar contact, when used by the controller during departure, should not
be interpreted as relieving pilots of their responsibility to maintain appropriate terrain and obstruction
clearance.
AIM goes on to say that Terrain/obstruction clearance is not provided by ATC until the controller beginsto provide navigational guidance in the form of radar vectors. Even this statement is a little misleading;
ATC is never solely responsible for your terrain/obstruction clearance. A better way to describe this
relationship would be to say, ATC does not begin to share responsibility for terrain/obstacle clearance
until the controller begins to provide navigational guidance.

Alert area airspace which may contain a high volume of pilot training activities or an unusual type ofaerial activity neither of which is hazardous to aircraft. Alert areas are depicted on aeronautical charts
for the information of nonparticipating pilots. All activities within an alert area are conducted in
accordance with FARs and pilots of participating aircraft as well as pilots transitioning the area are
equally responsible for collision avoidance
Controlled Firing Area airspace wherein activities are conducted under conditions so controlled as toeliminate hazards to nonparticipating aircraft and to ensure the safety of persons and property on the
ground
MOA airspace established outside Class A airspace area to separate or segregate certain nonhazardousmilitary activities from IFR traffic and to identify for VFR traffic where these activities are conducted
Prohibited Area designated airspace within which the flight of aircraft is prohibited Restricted Area airspace designated under FAR Part 73 within which the flight of aircraft, while not
wholly prohibited, is subject to restriction. Most restricted areas are designated joint use and IFR/VFR
operations are in the area may be authorized by the controlling ATC facility when it is not being utilized
by the using agency. Restricted areas are depicted on enroute charts. Where joint use is authored, the
name of the ATC facility is also shown

Runway end identifier lights (REIL) consists of two synchronized flashing lights, one of which is locatedlaterally on each side of the runway threshold facing the appropriate area
Visual approach slope indicator (VASI) system for final approach only. VASI glide slope angles arenormally adjusted to coincide with ILS and/or PAR glideslopes servicing the same runway. VASIs have
two separate blocks
Precision approach path indicator (PAPI) four light boxes installed in horizontal row on one side of therunway.
High intensity runway lighting (HIRL) elevated bidirectional lights, which extend by the length of therunway
Medium intensity runway lighting (MIRL) consists of elevated, omnidirectional lights, installed onrunways that are not to be used under IMC due to impaired clearance, short length, or other factors
Touchdown zone lighting two rows of high intensity light bars arranged on either side of the runwaycenterline. The two rows of light bars are 3,000 ft long and extend from the threshold of the runway
toward the rollout end of the runway

NOTAMs
All military bases and selected civilian fields are covered by the DoD NOTAM distribution system.Airfields covered by the DoD NOTAM system are designated by a diamond in FLIPs enroute supplement.
A darkened diamond means partial NOTAM coverage at a civilian field. Locations that have neither
diamond do not have approach procedures in FLIP and NOTAM information in not available on the
military NOTAM summaries
FAA NOTAMs
FAA D (Distant) contain information needing wide dissemination similar to DoD NOTAMs. D NOTAMSmay affect your ability to use a particular field or navigation facility. If your destination airfield is not
covered by the DoD NOTAM system, you may call any FSS to obtain this information
FAA L (Local) similar to DoD airfield advisories. L NOTAMs are less critical in nature. While L NOTAMswill not usually affect your ability to use a field, these NOTAMs will contain important information like
taxiway closures or VASI outages. The only way to obtain L NOTAMs is by contacting the fields servicing
FSS or by calling the airfield directly
FAA Flight Data Center (FDC) regulatory in nature and contains important information such asamendments to published approaches, chart changes, and TFRs
Notice to Airmen Publication NTAP contains FDC and other NOTAMs that meet the criteria of DNOTAMs and are expected to remain in effect for an extended period of time
