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?

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]

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.

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

What is the significance of a boxed or unboxed ECAM title?
Boxed means primary failure.
No box means independent failure.

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?

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.

DISCH 2 light appears after approx 40 min
After discharging Cargo fire bottle1, when will DISCH AGENT 2 light illuminate?
After 60 mins to remind you to discharge the second bottle
When does the LGCIU switchover occur?
On completion of gear retraction or upon failure
When is APU AVAIL memo displayed after APU start?
> 99.5%N or 2s after 95%
When does the ESS TR supply the DC ESS?
AC1 fail (Essential Feed should do this auto)
Or when emergency generator supplies the ESS TR
(DC ESS normally supplied via DC 1)
When are both bus tie contractors closed?
Both contactors are closed during single-engine operation,
or operation on the APU generator,
or external power supply.
What could PTU FAULT light signify?
Green or Yellow system:
- overheat
- low air pressure
- low level
(Light goes out when pb selected off, except for Overheat which lasts as long as overheat condition)

Memory items for Windshear after Takeoff?
"Windshear TOGA!” Thrust levers: TOGA AP (if engaged): Keep ON SRS orders: Follow Do not change Config until out of shear Closely monitor flight path and speed Recover smoothly to normal climb out of shear
If necessary full backstick
If no FDs pitch to 17.5° then as required to prevent height loss
Reactive: FAC computes low energy PM calls wind variations from ND When clear of shear report to ATC Warning Available: From 3s after lift off to 1300ft Ldg - 1300ft down to 50ft if Conf ≥1
EGPWS memory items?
“Pull up TOGA!” AP: Off Pitch: Pull up Thrust levers: TOGA Speedbrake level: Check retracted Bank: Wings level or adjust Do not change Config until clear of obstacle
Loss of braking memory items?
PF calls “Loss of braking!” Reverse: Max Brake pedals: Release Anti-skid OFF: Order Anti-skid & nose wheel steering: OFF Brake pedals:Press Max brake pressure : 1000 psi If still no braking: Parking brake: Use
Stall recovery memory items?
“Stall, I have control”
Nose down pitch control: Apply
Bank: Wings level
When out of the stall:Thrust Increase smoothly as required
Speedbrakes: Check retracted
Flight path: Recover smoothly
If in clean Config and below 20,000ft: Flap 1 Select
Stall warning at lift off memory items?
“Stall, TOGA 15” Thrust : TOGA At the same time; Pitch attitude : 15° Bank: Wings level When safe flight maintained, if stall warning continues, consider spurious
Emergency descent memory items?
“Emergency Descent” Crew Oxy masks: Use Signs: On Emer descent: Initiate If A/THR not active, THR levers: Idle Speed brake: Full
TCAS memory items?
“TCAS, I have control”
IF RA:
AP: Off
Both Flight Directors: Off
Respond promptly & smoothly
Respect stall / GPWS / windshear warnings
Notify ATC
The go-around procedure must be performed if RA CLIMB or INCREASE CLIMB is triggered on approach
When “CLEAR OF CONFLICT” announced resume normal navigation
Unreliable speed memory items?
“Unreliable speed”
AP: Off
Auto thrust: Off
FDs: Off
Below thrust reduction altitude: 15° / TOGA
Above thrust red alt and below FL100: 10° / Climb
Above thrust red alt and above FL100: 5° / Climb
Flaps; if Conf 0,1,2, or 3: Maintain current Config
Flaps; if full: Select 3 and maintain
Speedbrakes: Check retracted
Landing gear: Up
Autoland light triggers
RA <200 AND 1 AP engaged AND one of:
- LOC >1/4 dot
- GS >1dot
- Los of LOC signal >15 RA (Vertical FD flashes)
- Loss of GS signal >100 RA (Horizontal FD flashes)
- RA 1&2 difference >15ft
- Last AP disengages
- FMGS detects long flare
Jet stream min speed
