Flight Controls 3 Flashcards
If the TO waypoint has been passed in HDG mode,
It must be delete before an intercept in NAV mode
SRS is vertical mode. AEO – SRS – V2+ 10kt – ACC ALT / OEI
OEI – SRS – V2
OEI – target = highest – V2 ou current speed – limited by
V2 + 15kt
NAV enters at
30ft AFE
ALT selector knob – turn and push - _________ mode
Managed
ALT pb – immediate
Level off
V/S FPA – push -
Immediate level off
Magenta level off arrow – acft reaches altitude constraint / Blue start of climb arrow -
Acft resumes climb once waypoint is sequenced
The descent path is computed to reach Vapp at
1,000 ft AGL
V/DEV (vertical deviation) is difference between altitude on computer descent profile and
Actual acft alt. V/DEV on altitude scale on PFD and PROG on MCDU
Auto land warning if:
Both AP disconnect – excessive deviations in LOC (>15ft RA) or G/S (>100ft) or localizer signal is lost > 15ft or G/S > 100 ft RA, or difference > 15ft both RA.
Flight envelope protections:
Engine failure compensation; low speed and high speed protection; G load protection; flight mode reversions
In Alpha Floor , A/THR commands
TOGA thrust
A.FLOOR is lost in
Engine failure or A/THR failure
Reactive windshear for takeoff warning between
Lift off and 1,300 ft
Reactive windshear warning for approach between
50ft and 1,300ft at least Config 1
Mode reversion – if NAV disengages
Climb – open climb / descent – V/S
Mode reversion if FD not followed, i.e. Manual Flight, pitch up – speed reduces: and reaches VLS, A/THR reverts SPEED mode. Thrust increases to
Recover target speed. FD bars removed.
FD not followed and pitch down, speed
Increases
When acft VMAX – A/THR reverts to SPEED mode, FD bars
Removed. VMAX can be VMO, VLE or VFE
AP/FD – Backup MCDU – AP/FD still available. Abnormal but
Managed FMGEL cannot be engaged
Abnormal auto flight – Locked MCDU – No ECAM message -
Switch off, 10 sec, switch on/ loss of two FCU channels – FCU fault / Loss of three FCU channels – FCU fault
FCU – 3 channels. 1 fail – no ECAM action. 2 or more -
Fault – AP A/THR may be lost
The relationship between the pilot input on the sidestick, and the aircraft response, is called
the control law.
