My A320 gen refresher Flashcards
1
Q
What does IRS IN ALIGN mean?
A
Excessive motion detected or mismatch between the flight crew entered latitude and the IRS computed latitude
2
Q
When do you have to aurally ident a tuned Navaid?
A
If it is manually tuned on an RMP or the frequency is entered on the MCDU
3
Q
After an IRS alignment or at takeoff, what is the EPU set to?
A
0.2nm [DSC-22-20-20-20]
4
Q
When GPS primary is active, does the FM position update at take off?
A
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.
5
Q
Are there any restrictions affecting take off from a wet, dry or contaminated runway with a PADD?
A
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]

A
Yes. [PER-GOA-GEN]
7
Q

Q
What does “Reset IRS to NAV” mean on MCDU?
A

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]
9
Q
What does a red “SPD LIM” in bottom of PFD mean? [DSC-31-40]
A
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
10

Note: If LAND green not displayed <400ft, landing capability degrades to CAT1. Autoland not permitted with CAT1
displayed on FMA

15
Q
Where do the CPCs normally get landing elevation info from?
A
The FM (Hence if FM1+2 fail set ldg elev manually)
16

VMO/MMO are reduced (see ECAM STS) and Alpha Floor is inhibited
17
Q

Stall warning speed
Defined by the top of the red and black strip (Inhibited from touchdown until 5s after lift off)
25
Can the Hydraulic fire shut off valves be re-opened once automatically closed in flight?

26
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.
27
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
28

38
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
39
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.
40
What can cause the ECAM GWCG to diverge from the MACTOW?
