A320 ATA22 Auto Flight Flashcards
When the messages “MAP NOT AVAIL” and “SET OFFSIDE RNG/MODE” are displayes on the ND:
ND on the side with failed FMGC must be set on the range or mode as the other ND.
Which are the AP/FD basic modes?
HDG or TRK and V/S or FPA
Aircraft in clean configuration, operating in NORMAL LAW. When the angle of attack exceeds Alpha-Floor threshold, What happens?
TOGA thrust is applied regardless of thrust lever position from lift off to 100ft RA on approach
When both thrust levers are set on the idle detent, A/THR is disconnected. How could it be activated again?
Pushing the FCU A/THR pb while the thrust lever are within the active range. Including idle detent.
Choose the statment that keeps A/THR active:
-Both thrust lever are set to IDLE detent.
-Pushing A/THR on the FCU
-Listening the Auto Call-out “Retard”
-Pushing the instinctive disconnect pb on the thrust levers.
When listening to the Auto Call-out “retard”

“LDG capability” downgraded
The active FLT PLAN is erased when?
During DONE phase, 30s after LDG.
Which is the main input used to trigger the Alpha Floor condition?
AoA
FMGS’s and FCU run through various internal test:
-On ground, at elec. power up
-We must allow enough time (3 min) for test completition without pressing pb.
-In flight when there is a failure.
First 2
Rudder travel lim. is a function of?
FACs
Say in which case the AP will not disengage:
-If we override the side stick in roll.
-If we override the side stick in pitch.
-With a single failure of any MCDU.
-If we “override” at the same time on the three axis.
With a single failure of any MCDU.
The Flight Guidance provides the following functions:
AP, FD and A/THR
The radio navigation tuning function is performed by
The FM (flight management) part of the FMGC
On NEO acft with MSN 10830 - 11455. In the event of Alpha Floor engagement with A/THR ON.
Once the Alpha floor conditions are no longer applicable and speed is above VLS, the autothrust reengages automatically.
During normal FMGC operation:
One FMGC is the master while the other is the slave.
The FCU allow to:
Select the Guidance Targets AP/FD selected modes.
The AUTOLAND warning flashes with loss of GS signal between?
200 and 100 ft
About the rudder travel limitation function…
Limit rudder deflection based on speed in order to avoid high structural loads.
About YAW damping with AP engaged.
-Stabilizes the AC in yaw and coordinates the turns.
-The FMGC sends orders to the FAC to give yaw damping during approach.
-The FMGC sends orders to the FAC to give YAW controlf for runway alignment in ROLL OUT mode.
Thrust levers set in CLB, if the A/THR fails, what happens to the engine thrust?
Actual thrust is maintained.
During TO, the A/THR is?
A/THR is automatically armed but not active.
Which of the following AP/FD are managed modes:
NAV, APP NAV, LOC, RWY TRK, GA TRK
The main units of the FMGC are:
2 FMGC, 2 MCDU, 2 FAC, 1FCU
When electrical power is initially connected on ground, the MCDU will AUTO display:
STATUS page
If the message:”CHECK WEIGHT” appears on the MCDU. In which page can we correct the FOB or ZFW if necessary?
Fuel Prediction page
SRS TO mode disengages when one of the following occurs.
-FCU selected altitude is captured.
-Reaching acc. altitude.
-Another vertical mode engages.
ALL CORRECT-
We have the “EXPEDITE” mode engaged. To disengage it, one of the following actions is not correct.
Press again the “EXPED” pb
How can AP be engaged at the same time?
After arming APPR on the FCU on ILS, GLS or SLS app.
How is the active flight plan displayed on the ND.
With a GREEN LINE
When would the engine out procedure be automatically displayed on the MCDU if an engine fails?
Only during TO but before the diversion point.
What color is used to represent the engine out procedure on the ND?
Yellow
What are the FMGC main parts?
FM and FG
How often is the FMGC nav database revised?
Every 28 days
In which page of the MCDU can we view the FMGC tuned radio navaids?
Radio NAv and Selected NAC
BACK UP NAV mode is to be used only in case of FM 1+2 faiulre in MSN 3651 and subsequent.
TRUE
Alpha floor is available from lift off to 100ft RA on approach when the flight controls are in normal law.
True or False?
True
Gusts must not be inserted in the PERF APPR pages as GS mini takes into account the instantaneous gust
True or False?
TRUE
While taxing the following message appears on the ECAM: AUTO FLT FCU 1 FAULT. The flight crew must:
Act according to std failure procedure sequence, applying “System reset table” before reading STS and, as the last step if still necessary, consider applying the MEL
The FAC computes data for the flight envelope and speed functions. It also proves low energy functions and —-?
Windshear detection
Can we gly approaches based on Radio Aids with FINAL APP without “GPS PRIMARY”?
YES but reference navaid must be tuned and monitored during the approach.
Concerning position update at TO
It is never done with GPS Primary available.
On the aircrafts equipped with the FMS2 Honeywell the optimal cruising level shown on the MCDU
It will assume a minimum of 5 min at cruising level.
Concerning AUTO thrust reduction and retard mode?
The retard mode engages at aprox 30ft RA and remains engaged until both levers are set to IDLE
In an AUTO landing a RETARD callout is generated at 10ft.
How do we preset a HDG/TRK before a GO AROUND?
You can preset a HDG/TRK when LOC*, LOC, LOCB/C+, LOCB/C, LAND, FLARE, ROLLOUT or GA TRK are engaged,
We should TURN the HDG/TRK knob to select the desired value.
On MSN 6328 the VAPP, without in-flight failures, is limited between VLS+5 min, and VLS+15 as max?
TRUE
The AUTOLAND RED light bellow 200ft is triggered when?
The diff. between both radio altimeters indication is greater than 15ft.
If the AP/FD TCAS mode engages when flying with A/THR disconnected
The A/THR becomes armed or active depending on the thrust lever position
When the AP/FD TCAS mode is engaged, alpha floor is temporarily inhibited?
TRUE
When the AP/FD TCAS mode ARMS?
-FMA displays TCAS (blue) on the third line of the second column in FMA.
-If another vertical mode is armed (or engaged), this vertical mode remains armed or engaged.
-The AP and FD’s engagement status does not change
Which are correct?
ALL CORRECT
Select the right answer about the AP/FD TCAS mode when the “CLEAR OF CONFLICT” aural alert sounds
AP/FDTCAS mode auto disengage
AP/FD provides guidance towards the previous FCU selected altitude.
Flying in cruise we detect CAT3 dual inoperative in STS. The right answer is?
-This is only in A320 neo
-Usually the root cause is an ADR or IR rejection by FAC or FMGC
-If no other failure is detected, changing AP in command may allow the CAT 3 DUAL function to be recovered.
Answers B and C are CORRECT
About MCDU NAV B/UP (MSN 03651- onwards)
It allows the crew to monitor the navigation function and also provides some basic flight planning functions in case of FM1 + 2 failure.
Concernig AP/FD mode:
-It is a vertical guidance mode of the AP/FD
-The TCAS mode engages even if both APs and both FDs are disengaged
-If the TCAS mode engages when both APs and FDs are disengaged, HDG automatically engages.
ALL CORRECT
About AP/FD mode which are correct:
-The TCAS mode arms, when the TCAS TA is triggered.
-The TCAS mode engages when a TCAS RA is triggered.
-As soon as we set the TCAS MODE SEL or TA/RA before TO, the TCAS mode is armed during all flight. It engages when a TCAS RA is triggered.
ALL CORRECT
AP/FD mode conditions:
If the AP/FD TCAS mode angages, when lateral and vertical mode are engaged?
lateral mode remain engaged and vertical mode disengages
If a failure triggers the “FUEL CONSUMPTION INCRSD” message on the ECAM STS page complemented with a “FMS PRED UNRELIABLE” line…
You may use the surface’s flysmart app to compute fuel consumptions.
It highlights the unreliabilituy of the FMS.
The faiulre increases fuel consumption.
About the computed vertical profile flown on aircrafts with DESCENT PROFILE OPTIMIZATION:
Computed vertical profile is steeper
T/D is reached later
The deceleration level off is shorter
MCDU message “CHECK WEIGHT”
Is generated when the GW computed by the FMGC and the FAC diagree by more than 7T
Autoflight and AOC functions. AOC stands for?
Airline Operational Control
