My A320 gen refresher Flashcards
What does IRS IN ALIGN mean?
Excessive motion detected or mismatch between the flight crew entered latitude and the IRS computed latitude
When do you have to aurally ident a tuned Navaid?
If it is manually tuned on an RMP or the frequency is entered on the MCDU
After an IRS alignment or at takeoff, what is the EPU set to?
0.2nm [DSC-22-20-20-20]
When GPS primary is active, does the FM position update at take off?
No. The FM position update is inhibited when GPS PRIMARY is active. If GPS not primary, the FM position is
updated to the runway threshold at takeoff and corrected by the take off shift when entered by the flight crew.
Are there any restrictions affecting take off from a wet, dry or contaminated runway with a PADD?
Dispatch with up to two PADDs permitted on dry, wet or contaminated runways. Only ACARS, WEB or SMS RTOW
may be used with a PADD. [PER-TOF-ACA]
Can you follow standard missed approach during go-around with 2 engines but over MLW?
Yes. [PER-GOA-GEN]
Name 4 VOR approach considerations?
VOR location relative to the runway
FAT offset
MAPT location
Use of TRK/FPA
What does “Reset IRS to NAV” mean on MCDU?
The system has an initial position for IRS alignment, or the initial position has changed since IRS alignment, but none of the IRSs are in align mode. [DSC-22-20-50-20-30]
The MCDU INIT coordinates have been changed after the end of the IRS alignment.
Crosscheck the MCDU INIT coordinates against the IRS position on the MCDU POSITION MONITOR page. [PRO-SUP-34]
What does a red “SPD LIM” in bottom of PFD mean? [DSC-31-40]
Appears when both FMGCs fail (FE part) or incase of a SFCC dual flap/slat channel failure
In this case VLS, S, F, GD, Vtrend, Vmax, VFE, VFE next, VSW are lost
For landing with slats or flaps jammed, if SPD LIM flag is on PFD, use the MAX SPEED displayed on ECAM STS instead of the QRH table
Also appears if 2 ADR are wrong and differ, or if all 3 ADRS are erroneous
Can Visibility be factored on a VOR approach? [A.8.3.6.2]
No. Visibility cannot be factored for any approach.
Rule of thumb for decent planning?
(3xFL) +10 +10% tailwind component
3*FL) +((GS/10)-20
What 3 conditions are required for LAND GREEN?
LOC & GS modes engaged
A/c below 400ft RA
No action on the FCU disengages LAND mode
Disengages at TOGA thrust or 10s after landing if APPR pb pushed
Note: If LAND green not displayed <400ft, landing capability degrades to CAT1. Autoland not permitted with CAT1
displayed on FMA
What is the the APU fuel burn and where is the data located?
FCOM-PER-FPL
Ground ops 130 kg/h (Packs ON & 90 KVA load on APU GEN)
In flight 130 to 55 kg/hr
If the A/THR is failed, how may the crew try to recover it?
Engage the other AP then try to re-engage the A/THR
Note: if A/THR is recovered with AP2, A/THR will be lost again when AP2 is disengaged [PRO-ABN-22]
Where do the CPCs normally get landing elevation info from?
The FM (Hence if FM1+2 fail set ldg elev manually)
In Alternate Law what happens to VMO/MMO and Alpha Floor?
VMO/MMO are reduced (see ECAM STS) and Alpha Floor is inhibited
When is the use of A/THR not recommended?
In case of loss of autotrim function
What happens to the CDLS if DC Bus 2 fails?
The CDLS is not electrically supplied and is inoperative. No fault light appears on the center pedestal.
If no AP/FD pitch mode is engaged (ie AP and FS are OFF) what mode is A/THR in?
Speed [FCTM OP-30]
If flight crew select a speed on FCU in SRS?
Triple click alert and mode reversion to CLB or OP CLB occurs
Recommended crew actions upon ECAM advisory?
Time permitting PM reviews QRH ABN-80 [FCTM OP-40]
What is the significance of a boxed or unboxed ECAM title?
Boxed means primary failure.
No box means independent failure.
Can you rely on the ECAM LDG GEAR DN memo for gear position?
Yes, but should be backed up by the SD wheel page
What is VSW on the PFD speedscale?
Stall warning speed
Defined by the top of the red and black strip (Inhibited from touchdown until 5s after lift off)
Can the Hydraulic fire shut off valves be re-opened once automatically closed in flight?
No. [DSC-29-10-20]
What does ECAM memo TERR STBY mean?
In flight, the TERR STBY memo appears in green when the aircraft position accuracy (computed by the EGPWS) is insufficient to allow the enhanced TCF and TAD modes to operate.
These modes are not available until the TERR STBY memo disappears.
If selected, the terrain data display on the ND is automatically deselected, when the TERR STBY memo is
triggered. TERR OFF is displayed, when the EGPWS is voluntarily deselected.
If during a CAT2 or 3 approach tower informs that LVPs are suspended what type of approach may be continued?
Must revert to CAT1 minima
In case of an immediate return to land where flight does not exceed 1,500ft how do you view ECAM warnings?
Press RCL. TO inhibit stays until above 1500ft.
Explain Ground Speed Mini?
GS mini = VAPP minus tower head wind component as entered in Perf
Therefore IAS target = Vapp - tower HWC + current head wind component
Describe a procedure turn?
Turn left or right by 45°, timing 1min15s CAT D from the start of the turn. Then turn 180° opposite direction.
What is the difference between THR IDLE and THR DES?
THR IDLE - A/THR is active in thrust mode and commands idle thrust
THR DES - A/THR is active in thrust mode and commands a reduced thrust with DES mode
Define IAF, IF, FAF, FAP?
IAF - Initial Approach Fix
IF - Intermediate Fix
Begins on inbound track of procedure turn, base turn or final inbound leg of hold
Ends at the FAF or FAP as applicable
Where no FAF is specified the inbound track is the final approach segment
FAF - Final Approach Fix
Start of the Final approach
FAP - Final Approach Point
Start of final approach segment. Glideslope intercept point.
Does the TO config pb test for engine oil temp?
Yes, oil temp must be ≥50°. This applies when the pb is pressed and when TO power is set.
What are Alternate predications based on?
- A/c weight equal to landing weight at primary destination
- FL220 if <200nm diversion otherwise FL310
- CI 0
- Constant wind
- Constant ISA dev
- Airway distance for company route or direct distance for manually entered diversion
Up to what point can a Step Alt be entered?
Up to 50nm before TOD
What is the return to trajectory assumption?

After a rejected take off, if the aircraft comes to a complete stop using autobrake MAX, how would you release the brakes?
Disarm the spoilers. [PRO-ABN-10]
What does DMC 3 do and what happens if it fails?
DMC 3 is on standby ready to power any DU.
Nothing happens if DM3 fails but its not available as back up
What happens if the FDs fail just after take off and the pilot selects Climb thrust at acceleration altitude?
When the thrust levers are put in the climb detent the A/THR activates and because the FDs are off engages SPEED
mode. If the FCU target speed is less than actual speed the thrust will decrease.
What can cause the ECAM GWCG to diverge from the MACTOW?
Only the sensed fuel distribution can cause this. Use normal checklist table to determine the THS setting based on ECAM GWCG (provided within operational limit for take off) [PRO-NOR-SOP-07
In HDG/TRK when does a flight plan waypoint sequence automatically?
When a waypoint passes behind aircraft, within 7nm and aircraft track within 90° of next leg track [DSC-22-20-30]
What defines computed hold speed?
Default hold speed is lowest of;
max endurance speed
ICAO limit speed
speed constraint (if any)
What is max endurance speed?
Approximately equal to GD in clean config (varies from GD to GD+10kt) [DSC-22-20-30-10]
