Course Deviation and Heading Select information:

On FGCP:

• The FGCP Heading selection are used with the Flight Director and Auto Pilot functions whena certain heading must be flown. (Normally one would select a heading with the HDG knoband then press the HDG button on the FGCP- more information in section 3.8.1 .) Bothselectors are used to select the same data. Range [1°, 360°] with 1° increments.

• The FGCP Course selection is used to select the VOR/TACAN radial or ILS runway axis tointercept. Range [1°, 360°] with 1° increments.

• The HSI display for an ILS approach would be similar, except that ILS1/2 would be displayedin stead of VOR1/2.

• Nav source enables the selection of TAC (if installed), ILS1/VOR1, ILS2/VOR2, FMS1 orFMS2.

• When flying to an TACAN of VOR navaid, one dot on the course deviation scale represents5° of deviation.

• When flying to an ILS station, one dot on the course deviation scale represents 75 µA ofdeviation.

• When flying FMS, two dots on the course deviation represents:- 5 Nm in FMS navigation except approach,- 1 Nm in tactical navigation of terminal/approach,- 0.3 Nm in approach area,- any other RNP value inserted on FMS progress page(from 0.3 up to 20 Nm).

3.2 BASIC NAVIGATION

3.2.1 Bearing to Nav-aid

With this option it is possible to display the bearing to a selected Nav aid.

To activate (on EFCP):• Adjust the right BRG knob (↓)

to change the Nav-aid thediamond needle is pointing to.

• Adjust the left BRG knob (�)to change the Nav-aid thecircle needle is pointing to.

• The needles are removed when the"off" position is selected on the ↓and � BRG knobs.

Expected System Behaviour:• The selected Nav aids will be displayed on the PFD compass and the ND.

On PFD

Available Navaid:Left bearing knob enables the selection of(from left to right):• No dispay• VOR1• FMS1• ADF1 if installed• DF if installed• TACAN if installed

Right bearing knob enables the selection of(from left to right):• No dispay• VOR2• FMS2• ADF2 if installed (otherwise ADF1 if

installed)• DF if installed• TACAN if installed

On ND

• The name of the nav-aid is coming from the FMS. The FMS is looking at the 60 nearest nav-aids to find the corresponding frequency. FMS provides navaid ident only for VOR orTACAN navaid.

Note: If TACAN is in Air-to-Air (A/A) mode and if the frequency/channel used correspond toone of the 60 nearest nav-aids, the name of the nav-aid will be displayed but will correspond toa navaid from the database. Ignore the IDENT information in A/A mode.

3.2.2 FMS Nav-radio management

The MCDU can be used to get information on the NAV aids that are used by the FMS for BestComputed Position (BCP) computation, and to select whether they are tuned manually by theaircrew or automatically by the Flight Management System (FMS).

To Activate:• Press the TUNE button on the DATA page of

the MCDU.• Press the LSK beside AUTO/MAN for each

Nav radio to toggle between the two options(default is AUTO when the FMS is in BCPmode).

• A list of the nearest NAV AIDS are available:→ Press the LSK button beside NEAREST

on the display• It is also possible to deselect Nav-aids that are

known to be out of order:→ Press the LSK (line select key) beside

DESELECT line,→ Type the name of the defective Nav aid

in the scratchpad and→ Press the LSK beside an open line.

Expected System Behaviour:• BCP is always computed (whether selected or

not) for the FMS.• In Manual tuned mode, the FMS will still use

the selected radio for its BCP algorithm.• The radio-nav facility is used during BCP

computation to improve the accuracy of thecurrent position.

• Deselected Nav-aids will not be used for thecomputation of the BCP.

• The DME channel 3 is always autotuned bythe FMS.

• The "H" beside NAV1 means that DMEchannel 1 is in HOLD mode. (Same forNAV2)

3.2.3 Interception of VOR radial (without help from FD/AP)

TOPDECK can provide the pilot with sufficient information to perform a VOR radial capturewithout the help of the Flight Director or Auto Pilot.

To Activate:• Select V/L1 or V/L2 on the

FGCP to select the NAV-aidthat is displayed by thecourse deviation needle onthe HSI. (Use the leftselector knob for PFD1 andthe right selector for PFD2.)

• Confirm the used VOR frequency on the MCDU TUNE page or Navigation Display (ND).• Set the CRS selection to the desired radial.• Continue with normal VOR capture procedure.

Expected Symbology on PFD:

Phase 1: Interception of the VOR/LOC Phase 2: Following the radialTO the beacon

Phase 3: Overflying the beacon Phase 4: BacktrackingFROM the beacon

• During Phase 3 the VOR data can be erratic -even invalid (red cross over HSI).

• Change the CRS deviation needle if requestedfor further navigation purpose (e.g. flying anew direction while still using the same nav-aid in FROM mode).

3.2.4 Flying a basic ILS approach (without help from FD/AP)

TOPDECK can provide the pilot with sufficient information to perform a basic ILS approachwithout the help of the Flight Director or Auto Pilot.

To Activate:

• Select V/L1 or V/L2 on theFGCP to select the NAV-aid that is displayed by thecourse deviation needle onthe HSI. (Use the leftselector knob for PFD1and the right selector forPFD2.)

• Confirm the used ILS frequency on the MCDU TUNE page or Navigation Display (ND).• Tune the decision height, where you will decide whether to go around or land, on the side

ICP. (An audio warning is produced when the decision height is reached - see section onAudio Warnings - 6.1).

• Continue with normal ILS procedure.

Expected Symbology on PFD:

• The HSI display for an ILS approach would be similar to that of a VOR, except that ILS1/2would be displayed in stead of VOR1/2. (See section 3.1.5)

• The decision height can be set from 0 to 990ft (1ft increments).• Decision Height Alert

→ If the radio altitude is below DH + 100 ft, a box is displayed.→ If the radio altitude is below DH, the "DH" label is displayed inside the box.→ If radio altitude is not valid or if the selected DH data is not available, the reticle is not

displayed.• The PFD displays a navigation back course annunciator (BC) when ["aircraft heading" minus

"selected course"] > 105° (in absolute value) and ILS is the selected navigation source (seealso section 3.8.5 on back course interception).

3.3 SOURCE SELECTION FOR AP/FD OPERATION

By changing the active HSI of TOPDECK, it is possible to change the Primary and Navigationdata sources that are used as a reference by the flight guidance system.

3.3.1 HSI Selection

• By pressing HSI SEL repeatedly, the selected side changes. The active HSI is displayed onthe PFD of the non-selected side.

3.3.2 Implications of selection

For FD/AP operation:• The selected Primary Data source will be the one corresponding to the selected HSI (ADU1

and IRS1/AHRS1 for left HSI, ADU2 and IRS2/AHRS2 for right HSI).• The selected Navigation Data Source will be the one active on the selected HSI (left nav

source for left HSI, right nav source for right HSI).

3.4 BASIC AUTO PILOT FUNCTIONS

With the Basic AP funcitions it is possible for the auto pilot to maintain the selected pitch androll angles of the aircraft.• When the AP is engaged, the basic AP modes become active (pitch hold, roll hold, heading

hold).• All FD modes can be coupled to the AP (IAS, VS, ALT, ALT SEL, LNAV, VNAV, APP, BC,

HDG SEL).• In FD mode without AP, it is not possible to have the basic vertical and lateral modes

together. At least one FD mode must be engaged.• The Yaw Damper is automatically engaged when the AP switch is switched on.

3.4.1 Basic Vertical AP Mode (PITCH HOLD)

With the PITCH HOLD mode the AP maintains the pitch angle of the aircraft.

To activate:• Engage the AP switch on the

CEU. (PITCH HOLD is the defaultvertical mode when the Autopilot isengaged.)

• The PITCH HOLD angle of theaircraft (selection limited to ± 20°pitch) can be modified by:→ Moving the thumbwheel on the

CEU up or down (as shown on figure), or by→ using TCS. (See section 3.4.6)

Expected System Behaviour:• The value of the aircraft pitch at the moment of mode engagement becomes the target

PITCH HOLD value and is displayed in the FMA (1° resolution).• The FD guidance bars will be visible on the EADI (Electronic Attitude Director Indicator).

Limitations:• With AP/FD engagement, the pitch angle must be within ±20°• The AP disengages outside ±22° pitch• The FD disengages outside ±25° pitch• The TOPDECK system does not control

the aircraft throttle.

Note:• All upper vertical modes revert to this basic

vertical mode (PITCH HOLD) when they disengage.

3.4.2 Basic Lateral AP Modes (ROLL HOLD, WINGS LEVEL and HEADING HOLD)

With these modes the TOPDECK AP maintains the selected roll angle of the aircraft when it isin ROLL HOLD and WING LEVEL mode, or the current heading in HEADING HOLD mode.

To activate:• Fly the aircraft manually at the required

roll angle.• Engage the AP switch on the CEU.• The roll angle (and therefor the basic

AP lateral submode) of the aircraftcan be modified by:→ Turning the TURN knob on the

CEU and then releasing it whenthe FD guidance bars on the EADI (Electronic Attitude Director Indicator) reach therequired angle, or by

→ using TCS. (See section 3.4.6)

Expected System Behaviour:• The roll angle at the time of AP/FD engagement will be used as the target roll angle (if it is

between ±6° and ±30°, e.g. -12° or +23° - see Limitations)• For roll angles within ±6° at AP/FD engagement, the target angle will be 0° roll.• ROLL HOLD and WINGS LEVEL are the default vertical modes when the Autopilot is

engaged, depending on the aircraft roll angle at the moment of engagement.• The FD guidance bars will be visible on the EADI.

The basic lateral mode is composedof three submodes:• "ROLL HOLD" submode, which consists of

holding a roll angle target. It is selectedwhen the Roll Angle > ±6° and < ±30° atengagement of the mode.

• "WING LVL" submode, which commands theA/C to a 0° bank angle. It is selected whenthe Roll Angle < ±6° at engagement of themode.

• "HEADING HOLD" mode, which is a specialcase of the WING LVL mode and consistsof holding the actual heading. It isselected automatically when the bankangle is less than 3° for more than 10seconds in WINGS LEVEL mode.

Limitations:• With AP/FD engagement, the roll angle must be within ±30°• The AP disengages outside ±35° roll.• The FD disengages outside ±60° roll.• The TOPDECK system does not control the aircraft throttle.

3.4.3 Yaw Damper Mode

With the Yaw Damper mode the TOPDECK system controls the YAW controlling interface ofthe aircraft to ensure co-ordinated turns.

To activate:• Engage the YAW switch on the CEU.

Expected System Behaviour:• TOPDECK will ensure co-ordinated

turns of the aircraft.

Note:• It is possible to engage the YAW

damper without engaging the AP, butit is not possible to engage the APwithout the YAW damper because ofthe mechanics of the switches.

YAW damperswitch




3.4.4 Auto Pitch Trim

With the Auto Pitch Trim function it is not necessary to trim the aircraft pitch manually.

To activate:• The Autotrim option must be selected

on the central pedestal of the aircraft.• The Auto Pitch Trim is automatically

activated whenever the AP isactivated and TCS is not active.

Expected System Behaviour:• The manual pitch trim setting will be ignored when the autopilot is engaged, except when the

manual pitch trim setting is changed by the aircrew, in which case it will cause thedisengagement of the AP (and consequently the Auto Pitch Trim function).

• When ’MISTRIM’ information messagesare displayed, the crew shouldanticipate a force on control column atAP disengagement and then take actionas the information message suggested.(MISTRIM message privides a status,not a command.)

• MISTRIM messages does not cause AP disengagement when a slight mistrim occurs. Whensubstantial mistrim occurs, the AP will disengage automatically.

Failure:• In case of a trim failure, the AP

disengages.• Trim failure can be detected when:

→ Out of trim condition for more thanacceptable time

→ TRIM command discrepancybetween autopilot command and monitor channels.

• AP engagement is inhibited as long as theAP PITCH/TRIM FAILure remains.(Inhibit message visible for 5 sec.)




3.4.5 AP/YD and FD Engagement conditions

On ground:• AP/YD can be engaged on ground for check test purpose only when ground speed < 30 kts.

(The ground speed is coming from the selected FMS.)• FD can be engaged on ground, without speed limitation.

In Air:• FD operation is always allowed.• AP engagement is not allowed for 15

seconds just after take-off.• AP engagement will be inhibited when

an AFCS external failure conditionexists. When an attempt is made toengage the AP, a inhibit message willbe displayed for 5 seconds.

• When AP is engaged, the defaulthorizontal mode is WING LVL (aircraftroll angle < ±6° at engagement) andthe default vertical mode is PITCHHOLD.

3.4.6 Changing targets without disengaging Auto Pilot (Tactile Control Steering)

With the TCS function it is possible to manually control the aircraft without disengaging thecurrently engaged AP or FD mode(s).

To activate:• Press and hold the TCS button on the steering column of either the pilot or co-pilot.• Fly the aircraft manually while pressing the TCS button.• Release TCS button to return to AP.

Expected System Behaviour:• When the TCS button is pressed, the AP will stop controlling the aircraft.• When the TCS button is released, the autopilot (or FD when autopilot was not engaged

before pressing the button) will→ follow the new references for the following AP modes: HDG HOLD, IAS, VS and ALT

HOLD, or→ return to the previous selected datum for the AP modes: VOR/TACAN Navigation,

LOC, BC, FMS Navigation, ALT SEL, HDG SEL and GA.




Example:• The aircraft is flying with AP engaged.

HDG HOLD is the lateral mode and VS+1500 is the vertical mode.

• The TCS button is pressed on one of thecontrol columns in the aircraft. Theaircrew flies the aircraft manually whiledepressing the TCS button.

• The TCS button is released and the APuse the new target values for headingand vertical speed (VS -200).

3.4.7 AP/YD Failure

YD Failure:In case of a YD failure:• AP/YD FAIL will be displayed on the

PFD’s.• Engagement of YD or AP/YD disabled.• All modes can still be used in FD

operation.

AP Failure:In case of a AP failure:• AP FAIL will be displayed on the PFD’s.• Engagement of AP is disabled.• Engagement of YD is allowed.• All modes can still be used in FD

operation.




3.4.8 Disengagement of Auto Pilot

To disengage manually, use one of the following methods:• Deselect AP or YD switch on the CEU.• Press instinctive disconnect button on control column.• Press the Go-around button (if you are flying an AP approach and you want to execute a

missed approach). This will cause the disengagement of AP and YD.

Automatic disengagement happens when:• aircraft attitudes are out of ± 35° roll and ± 22° pitch,• any of the ADUs or IRS/AHRSs are not valid,• the aircraft is on the ground with ground speed > 30kts,• a discrepancy has been detected on ADU or IRS/AHRS,• pitch trim control is set to OFF,• substantial mistrim occurs which the AP cannot correct,• manual pitch trim is performed,• the AP is overrided by the pilot by using force on the control column,• stall warning is active.

Expected System Behaviour:• When the AP is disengaged, the AP warning lights are set on the Caution and Warning Panel

and the "AP/YD DISENGAGED" or "YD DISENGAGED" are displayed on PFD:→ for 5 seconds steady if AP is intentionally disengaged,→ flashing when AP automatically disengages until crew acknowledgement (by means of

the instinctive disconnect button on the control column) then set steady for 5 seconds.• An audio warning is produced at AP

disengagement (see section on AudioWarnings - 6.1).

3.5.6 Dropping During a Tactical Flight (Practical Example)

The following flight plan has been selected on the MCDU and is displayed on the ND DUs:

The dropping zone is the tactical waypoint 120.

By using the LNAV AP/FD mode, the A/C will fly along leg 1. On leg 2, the FMS will computethe CARP depending on the wind, parachute, dropping height and weight of the load. (TheTOwaypoint ident will be "CARP".) The FMS will provide lateral guidance with an offset on theactive leg (the "OFST" flag will be displayed with the new desired track; the initial leg, (leg 2) isnot displayed in order to avoid clutter). After the CARP, the FMS will maintain the guidancewith the same track for 2 NM. After 2 NM, the FMS will capture the next leg (leg 3) with anintercept angle of about 45°.




3.5.7 Lateral Navigation Following

Expected System Behaviour:• Just after ALT SEL is pressed, the PFD

will show that the ALT SEL is armedwhile the PITCH HOLD, VS or IASmode active (depending on previousvertical mode).

• 1000ft from the selected altitude, the

altitude audio warning will sound andthe altitude alert flag wil be displayed inreverse video.

• The altitude alert flag will revert to normaldisplay closer than 200ft from theselected altitude.

• When altitude capture conditions are met,the ALT SEL mode becomes active inits capture phase ("ALT*" is displayedon the FMA).

• When the selected altitude is reached, theALT mode is automatically engaged("ALT" is displayed on the FMA).

• When the FD is used on its own, the FD guidance bars on the EADI will have to be followedto intercept the altitude.

Limitations:• The AP will use pitch variations to control the altitude of the aircraft. (The TOPDECK system

does not control the aircraft throttle.)• Pilots have to be very careful with the engine setting during this dynamic phase.

Conditions to activate ALT mode:• Dependant of aircraft vertical speed.

3.9 ILS APPROACH USING FD/AP

3.9.1 Approach with CAT II Minima

With this approach mode (CAT II Minima - decision height of 100ft) it is possible for the autopilot to fly the aircraft to the decision height on the landing approach by using the airstrip ILS.

Overview:• Phase A: Intercept the localiser beam by using the heading select mode of the AFCS:• Phase B: intercept the glideslope beam (always after localiser interception)• Phase C: track the ILS beam.• Phase D: Go Around or manual landing.




To activate:

(In the following description, it isassumed that no DME distanceis available. The left sidesettings of the FGCP arereferred to as the pilot side, and the right side is referred to as the co-pilot side.)

Phase A (heading select phase)• Lateral AP/FD mode engaged: heading select (heading: 030°) using "HDG" button of the

FGCP.• Vertical AP/FD mode engaged: altitude hold using "ALT" button of the FGCP.

Preparation of phase B (localiser and glideslope capture and tracking)• Select the course corresponding to the runway course (e.g. 090°) by using

the two CRS knobs on the FGCP (same selection for pilot and co-pilot).• Confirm the used ILS frequency (e.g. 110.30) on the MCDU TUNE page or

PFD/ND.• Select the navigation source: "V/L1" for the pilot and "V/L2" for the co-pilot

with the left and right NAV SOURCE knobs on the FGCP.• Select the decision height (e.g. DH = 100 ft) with the DH knob on the ICP.• Select the dual approach mode by pressing the "APP" and then the "CAT2"

buttons on the FGCP.

Phase C (excessive deviation monitoring)• Keep a watchful eye on the PFD and be ready to take corrective actions if

necessary.• Decide whether to Go Around or land the aircraft manually when the aircraft reaches the

decision height.

Phase D (landing)• Land the aircraft manually.

Go Around• Press the Go Around button on the control column and follow the flight director guidance

bars.

Expected System Behaviour:

Phase A (heading select phase):• The FD guidance bars will be visible on the EADI (Electronic Attitude Director Indicator).• Until the localiser capture conditions have been met, "HDG SEL" mode will remain active.• Lateral or vertical deviation is not displayed on the EADI or HSI until valid reception from the

VHF receivers are established by the system.• FMA symbology (Phase A):

Phase B (localiser and glideslope capture and tracking)




• When the localiser beam is near, the "HDG SEL" mode is disengaged and the "LOC*"(localiser capture phase) mode engaged (the start of the capture phase is determined bythe level of the localiser signal and by the interception angle of the radial).

• The heading of the runway is selected as the actual selected heading (e.g.090°).• When the glideslope beam is near, the "PITCH HOLD" mode is disengaged and the "GS*"

(glideslope capture phase) mode engaged (the start of the capture phase is determined bythe level of the glide/slope signal).

• The system will then capture first the localiser and then the glideslope beam (lateral mode willbe "LOC" and vertical mode will be "GS" after successful capture).

• FMA, EADI and HSI symbology (Phase B):

Phase C (excessive deviation monitoring)• ILS deviations are monitored below 300 ft R/A.

In case of excessive deviation (localiser = ±25 µA, glide/slope = ± 75 µA), warnings aredisplayed (ILS deviation scale and displayedflanking in yellow).

• An audio warning is produced when the decision height is reached (see section on AudioWarnings - 6.1).

Phase D (landing)• "LOC" and "GS" modes will remain active until invalid reception of the glide slope deviation.• The glide slope vertical deviation will be displayed until invalid reception from the VHF

receiver.• The localiser lateral deviation is displayed until the end of the roll-out

GA phase (Go Around)• when the GA button is pressed, the AP is automatically disengaged.• the "GA" vertical FD mode will engage (giving a fixed pitch up command at 7°with the

command bars)(See section 3.7.5 for details.)




3.9.2 Approach with CAT I Minima

With this approach mode (CAT I Minima - decision height of 200ft) it is possible for the autopilot to fly the aircraft to the decision height on the landing approach by using the airstrip ILS.

To activate:• Select a LOC (V/L1 or V/L2)

NAV source on the FGCPon the side you are sitting.

• Confirm the used ILSfrequency on the MCDUTUNE page or PFD/ND.

• Select a Course Target (theILS localiser direction that you want to intercept) with the CRS knob on the FGCP on theside you are sitting.

• Select an intercept HDG target with the HDG knob.• Press the APP button on the FGCP to arm the LOC lateral mode and the Glideslope (GS)

vertical mode.

Expected System Behaviour:• Previously engaged lateral and vertical modes remain active until the corresponding lateral

and vertical Approach modes are in capture phase.• The FD guidance bars will be visible on the EADI (Electronic Attitude Director Indicator).• When the Localizer capture conditions are met, the LOC mode becomes active in its capture

phase ("LOC*", "GS*" are displayed on the FMA).• If no mode was engaged when APP push button is pressed, then HDG SEL and PITCH

HOLD modes will automatically engage untill the capture conditions are met for thelocaliser and glideslope capture.

• When the LOC inbound course is captured, the track phase is active ("LOC" is displayed onthe FMA).

• When the Glide Slope capture conditions are met, the GS mode becomes active in itscapture phase. GS capture cannot occur prior to LOC capture. When the Glide slope iscaptured, the track phase is active ("GS" is displayed on the FMA).




3.9.3 Back Course Approach

With the Back Course Approach mode it is possible to approach the airstrip for a landing byusing the back course of the airstrip ILS Localiser.

Overview:• Phase A: intercept back course

of the localiser by using theheading select mode of theAFCS

• Phase B: tracking back courseof the localiser by using the"BC" mode of the AFCS

• Phase C: using procedure turnfor normal recovery in front ofthe localiser beam

• Phase D: tracking the ILSbeam (see "ILS approach"section).

To activate:(FGCP selections using theCOURSE, HDG and NAVSOURCE knobs in thisexplanation are from the leftpart of the FGCP. The HSISEL button on the FGCP mustbe used to activate the use ofthe left COURSE, HDG and NAV SOURCE knobs before commencing the Back CourseApproach.)

Phase A:• Engage lateral AP/FD mode - "heading select". Select a heading to cross the runway

longitudinal axis approximately over the runway threshold by turning the HDG knob on theFGCP to the required heading and then press the "HDG" push-button.

• Engage vertical AP/FD mode - "altitude hold" using the "ALT" push-button on the FGCP.(This is a vertical mode that will be active throughout the Back Course Approach and itfunctions separate from the Back Course Approach, which is an upper lateral mode.)

Preparation of phase B (back course):(Execute these steps before crossing the runway.)• Select the course corresponding to the runway course (e.g. 270°) with COURSE knob on

FGCP.• Confirm the used ILS frequency (e.g. 110.30MHz) on the MCDU TUNE page PFD/ND.• Select the navigation source (e.g."V/L1") on the FGCP with the NAV SOURCE button.• Select the "BC" mode (Use the "BC" push-button on the FGCP)

Phase C and D (turn around and intercept of ILS localiser)• (In this example we will be making an about turn on the left side of the ILS localiser - see

picture above.)




• When overflying the outer marker, select a new heading 45° to the left of the current headingwith the "HDG" button on the FGCP (select 045° in this case). Engage the "heading select"mode by pushing the "HDG" button on the FGCP.

• Fly 1 min.• Select a reciprocal heading value with the "HDG" button on the FGCP (select 225° in this

case) in order to be able to capture the localiser with a right turn. (This will be a "hotchange", which means the aircraft will begin to follow the new selected heading themoment you change the value with the "HDG" knob, so be quick! Turn the "HDG" button ina clockwise direction.)

• "APP" mode will be selected to arm the ILS approach mode.

Expected System Behaviour:(Symbology examples are provided for the pilot [left] PFD.)

Phase A (heading select phase)• The FD guidance bars will be visible on the EADI (Electronic Attitude Director Indicator).• The aircraft will fly on the selected heading and altitude towards the runway threshold with the

"HDG SEL" mode active.• After the BC button is pressed, the "HDG SEL" lateral mode will remain active with the "BC"

mode armed, until the back course localiser conditions have been met, and then the "BC"upper lateral mode will become active.)

• Lateral deviation is not displayed on the PFD until a valid reception from the VHF receiver isestablished by the system.

• FMA symbology (Phase A):

Phase B (Back course phase)

• When the localiser beam is captured, the "HDG SEL" mode is disengaged and the "BC*"mode engaged (capture phase is determined by the level of the localizer signal and by theinterception angle of the radial).

• The system will then track the localizer beam (lateral mode will be "BC").




• FMA, EADI and HSI symbology (Phase B):

Phases C and D (Turn)• When the "HDG SEL" mode is engaged just after the middle marker, the A/C will follow the

new selected heading as the first of the two turn-around actions.• After 1 min the aircraft will turn around and be ready to intercept the ILS localiser.• FMA and HSI symbology (End of Phase D):

The BC mode can also be used forautomatic capture and tracking of theback course localiser signal. The BCmode is then set up and flown exactlylike the front course localiser approach.




3.10 AVOIDING TRAFFIC COLLISIONS

With the Traffic Collision and Avoidance System (TCAS) it is possible for the pilot to be awareof evolving air collisions. In the event of a possible air collision, it advises the pilot on astrategy to avoid the air collision.

3.10.1 Activation of Warning System

To activate:• Repetitive presses of the TCAS button will cycle through the modes AUTO and full display.• AUTO mode will display intruders automatically whenever a RA or TA is present.• Full display mode will display all intruders whatever their criticality.• Fly the aircraft to the green band on the IVSI (change the aircraft’s vertical speed) to avoid

traffic collisions.• See TCAS Management (section 4.7.1) for TCAS display modes and operational modes.

Expected System Behaviour:• TCAS symbology will be overlayed on the PFD (compass and IVSI) that corresponds to the

EFCP (pilot EFCP for pilot PFD).• When threats exist (Resolution Advisory), the IVSI will become a command instrument that

advises the pilot to change the aircraft’s vertical speed to avoid traffic collisions.

3.10.2 Types of air traffic/threat situations

• Resolution Advisory (RA): Air traffic with a flight path that has a high probability of collisionwith your own aircraft is classified as a Resolution Advisory situation. A RA recommends avertical speed strategy to provide appropriate vertical separation from the threateningintruder.

• Traffic Advisory (TA): Air traffic with a flight path that might develop in a possible collisionsituation with your own aircraft is classified as a Traffic Advisory situation. A TA callsattention to a developing collision threat.

• Proximate Traffic (PT): Non-threatening, air traffic closer than 6 Nm are classified asProximate Traffic.

• Other Traffic (OT): All other detected air traffic not designated RA/TA/PT will be classified asOther Traffic.

• No Bearing Advisory: When no bearing information (position relative to your own aircraft) ofa RA or TA intruder is available, they are displayed in the No Bearing Advisory Field.

3.10.3 Other TCAS messages/options

StatusIn the top middle of the ND, different status messages can be displayed.• TCAS FAIL indicates a TCAS failure.• TCAS TEST indicates that a TCAS self test are being performed.• TCAS STBY indicates that TCAS is in standby mode. No TCAS advisories are displayed.• TCAS TA ONLY indicates that TCAS will send all RA (Resolution Advisories) to the display as

TA (Traffic Advisories).• TCAS indicates that TCAS is active in TA/RA mode (the normal operational mode).• the ABV (above) option enables the display of tracked traffic from 2700 ft below the own A/C

to a maximum of 9900 ft above the own A/C,• the BLW (below) option enables the display of tracked traffic from 9900 ft below the own A/C

to a maximum of 2700 ft above the own A/C,• the ABS option enables to display the absolute corrected altitude instead of the relative

altitude for all the intruders (Active only when no RA or TA is detected).

Range• In the AUTO mode (default), intruders classified as PT or OT will only be displayed when a

RA or a TA situation exists.• The TCAS Inner Range Ring always has a radius of 2Nm in any range setting, and will be

displayed in the 5 Nm and 10 Nm range.• When an intruder is outside the selected display range, it is displayed at the edge of the HSI

dial scale with about one half of the symbol obscured.• Up to 30 intruders will be displayed on the ND.

5 SYSTEM ARCHITECTURE

The TOPDECK® avionics system consists of the following major subsystems:

- a flight management system connected to an inertial reference system with an embedded code-PGPS and/or srandaolne code-P GPS

- an EFIS system which displays flight and navigation information to the pilot and co-pilot- an Automatic Flight Control Subsystem (AFCS) which include a flight director guidance and

autopilot system- a centralized Radio Management System which is capable of controlling radio navigation and

communication units- a centralized maintenance system which is capable of recording all avionics failures for up to 30

flights- primary references and navigation sensors including ADU, AHRS, MMR, radio altimeter,

standalone code-P GPS

TOPDECK® has a dual system architecture regarding all its functions and hardware, except for theAFCS control panels (FGCP and CEU) of which there are one of each.

The TOPDECK® avionic system is linked to external subsystems:

- Radio-navigation sensors: DME, TACAN, ADF, DF- Radio-communication transceivers: IFF, V/UHF, HF- External protection equipment: WXR, ETCAS, EGPWS- Engine Instrument Display

The main pieces of equipment that interacts with the TOPDECK® system by either receiving orproviding information in data format are:

- Radio Navigation Receivers ARINC 429 / MIL-1553- Radio Communication Transceivers MIL-1553- Weather Radar WXR ARINC 453- Radio Altimeter ARINC 429- Fuel Flowmeters ARINC 429- Air Data Pressure Tubes Pneumatic- Temperature Probe DC (4 wires)- Switches and Discretes 0/28V- Power Supplies 28V and 115V (400Hz)- Cooling- ETCAS ARINC 429- EGPWS ARINC 429 / ARINC 453- MLS (option) ARINC 429




5.1 FLIGHT MANAGEMENT SYSTEM

The flight management system provides lateral and vertical navigation capabilities including RNPmanagement.

It is based on dual Flight Management Modules (FMM) (situated in the Integrated Flight Cabinet).

User interface with the FMM is provided by both MCDUs. An Air Data Loader (ADL – a type of datadiskette drive) and the Data Transfer Module (DTM – a type of data diskette) are used to upload datato the FMS that has been prepared on a ground-based Flight Planning System (standard and userdatabases, radio frequency plans, ...).

5.2 FLIGHT DECK SUBSYSTEM

The Flight Deck Subsystem (FDS) consists of an Electronic Flight Instrument System (EFIS)supplemented by an Integrated Electronic Stand-by Instrument.

The Electronic Flight Instrument System (EFIS) has a dual system architecture and consists of thefollowing elements:

- each pilot have a Colour LCD Primary Flight Display (PFD) and Navigation Display (ND)- each of the aircrew has an EFIS Control Panel (EFCP) to control the information displayed on

their PFD and/or ND (e.g. symbology brightness, ON/OFF switches of display units, selection ofdisplay modes).

- two Index Control Panels (ICP) are used to set parameters on the PFD (decision height, speedbugs and QNH settings).

The EFIS is capable of displaying data as provided by the weather radar, Enhanced TCAS andEnhanced GPWS.

5.3 AUTOMATIC FLIGHT CONTROL SUBSYSTEM (AFCS)

- the Flight Guidance Control Panel (FGCP) controls the modes of operation of the Automatic FlightControl Subsystem (AFCS): heading, course, altitude, speed, flight director modes selection,

- the Control and Engagement Unit (CEU) controls the engagement of the Autopilot (AP) and YawDamper (YD) functions and provides selection of basic pitch attitude and turn command,

- the Flight Guidance Module (FGM) (situated in the Integrated Flight Cabinet) is the processingunit of the AFCS for all flight guidance and autopilot computation,

5.6 INTEGRATED FLIGHT CABINET (IFC)

The TOPDECK® system includes two racks that can hold several computer cards/modules. Theracks are called Integrated Flight Cabinets (IFC). This architecture was chosen to centralise theTOPDECK® system’s data input and avoid unnecessary duplication e.g. power supplies forcomputer modules of each subsystem. Each IFC hosts the following modules:

- The Primary Power Supply module (PPSM) supplies the necessary electrical power to themodules

- The Input/Output Processor Module (IOP – own CPU) performs data concentration with digitaldata from ADU, VOR/DME, TACAN, Radio ALT and flowmeters

- The Input/Output Module (IOM) serves as an interface between outside sensors and the IOP- The Flight Management Module (FMM – own CPU)- The Flight Guidance Module (FGM – own CPU)




6 FAILURE MANAGEMENT

6.1 AUDIO WARNINGS

6.1.1 Audio Alerts

The system provides a set of aural alerts for:

- Auto Pilot disengagement: this aural alert is provided when autpilot is disengaged intentionallyor not

- DH alert: this aural alert is provided when going through the DH in approach- Altitude alert: this aural alert is provided when acquiring or departing from the selected altitude

on the FGCP

6.1.2 Audio warning computation

Audio warning prioritiesThe audio warnings is prioretized as follows (from higher priority to lower priority):

- AP disengage- DH alert- Altitude alert.

Audio warning synchronisationBoth IOPs synchronize each other so that only one audio output is provided at the output ofTOPDECK®.

Autopilot disengagement audio warningThe AP disengage audio warning is provided by both FGMs through the IOPs. It is reset bydepressing the instinctive disconnect switch (in case of intentional disengagement, audio warning isplayed once).

AP disengage audio warning characteristics

The AP disengage audio warning has the following characteristics:The minimum duration of the audio warning is 1 full cycle.

Audio DH warningThe IOP activates an audio warning when DH alert is set by

- pilot PFD if DH used on PFD is greater or equal to DH used on co-pilot PFD- else by co-pilot

6.2 VISUAL WARINGS

When primary parameters are failed (air data, attitudes, heading, …) the following symbology will bedisplayed on the PFD to request manual reversion to the remaining valid sensor:

On ND

Display Unit Hot: DU HOT will appear in white at around +55°C internal display temperature and inamber at around +75°C internal temperature. When the warning is displayed in amber, display mayautomatically shutdown.Recommendation: Set the display brightness to the minimum setting until the message disappears.

"Display Unit Hot"Warning




6.3 SOURCE SELECTION AND REVERSION

The AFCS, FMS and EFIS manage primary source selection according to the following rules:

- if the ADU or AHRS reversion switches are set to both on 1 or both on 2, AFCS, FMS and EFISwill use the selected source for their own computation and displaying;

- if the ADU or AHRS reversion switch is set to normal:→ PFDs and NDs will use own side sensor even if data are not valid (for example ADU1

selection for pilot PFD and ADU2 selection for co-pilot PFD),→ FMSs will use own side sensor if data is valid and opposite side sensor if own side data are

not valid,→ AFCS will use the HSI side primary sensor (FGCP selection): if left HSI is coupled, ADU1 and

AHRS1 sensors are used; if right HSI is coupled, ADU2 and AHRS2 sensors are used. Incase of failure of the selected sensor, FD mode using failed data are disabled.

On the MCDUs, the used sensors are identified by an "*" on the HDG/ATT page and displayed as"ADU1" or "ADU2" on the AIR/RA page (DATA VOLUME).

On the EFIS, the sensor source is not displayed when in normal configuration. When in both on 1 orboth on 2 configuration a selection reminder is displayed.

The navigation sensors (VOR, TACAN and FMS) are selected using the FGCP. If the navigationsource is not set to FMS1 or FMS2, the ND will use FMS data coming from the own side FMS if validand opposite side FMS otherwise (for example if left nav source is TAC, the pilot ND will use datacoming from the FMS1 if valid, FMS2 otherwise).

6.4 FAILURE AND REVERSION MANAGEMENT

In case of PFD failure, the PFD image can be displayed on the ND by setting the PFD brightnessknob of the EFCP to the OFF position. The ND image is then no longer available on the ND display.If the PFD is switched on again, and if it detects that fatal failure has occurred before switch off, thepower-on self-tests will be performed. If the PFD becomes healthy, the PFD image will be availableagain and the ND will revert to the normal ND display. At power-on, if the ND is powered before thePFD, it will display a PFD image at the end of its own self-tests. A ND image will be displayed only atthe end of the PFD self tests.

In case of ND failure, no manual or automatic reconfiguration can be performed.

In case of one equipment failure (ADU1 or 2, AHRS1 or 2), the associated symbols are notdisplayed and the appropriate warning messages are displayed (see description in paragraph 3.4).The crew can use reversion switch (located on the pedestal) to disable the failed source and toselect the same source for both pilot and co-pilot sides.




In case of ADU reversion, the barometric setting will be controlled by the ICP which is on theselected side (ICP1 when "BOTH ON 1" and ICP2 when "BOTH ON 2").

The same reversion capability as for ADU/AHRS is provided for the radio altimeter (in case of dualconfiguration): both on 1, normal, both on 2 selection can be performed.

In case of failure of the 1553 bus controller, adequate warning is provided in the RMS messagevolume ; a reversion switch located in the cockpit enables to perform a reversion on the remainingvalid IOP.
