A320 Overhead Panel Flashcards
(22 cards)
What does the ADIRU ON BAT light mean? How long will the light remain on for?
The aircraft batteries are powering one or more ADIRU; it also comes on briefly during alignment.
The ON BAT light will remain illuminated for 5 minutes to retain alignment data to allow a geneator reset. ADIRU 1 light will remain on
What does a flashing FAULT light on the IR panel mean?
A flashing fault light means ATT & HDG may be recoverable
What does a steady FAULT light mean on the IR panel?
A steady fault light means the IR is lost
What does a flashing ALIGN light mean on the IR panel?
There is an alignment fault on the associated IR
- no present pos entered after 10 minutes; or
- 1 degree of difference between ppos and memorised position
A dual IR failure will increase LDR because anti-skid is lost
What happens when the nav selector is placed in nav mode?
This is the normal position for alignment and navigation.
Full alignement takes 7-10 minutes
Fast alignment takes 3 minutes and is available only if the IRs were previously aligned; fast alignment must be done when the IRS Position differs by 5nm or more from the FMGC position
What does the IR ATT rotary knob selector position do?
It is used to retain attitude and heading when the IR has a fault
What does the ADR push button FAULT light and OFF light mean?
The ADIRU has a fault, when selected off the white OFF light illuminates
What does the GEN 1 LINE p/b do?
It opens the gen 1 line contactor while still powering the number one fuel pump in each main tank
What does the GEN 1 SMOKE light mean?
Smoke has been detected in the avionics vent extract duct for more than 5 seconds
What does the EMERG GEN TEST P/B do?
It is for maintenance to test the RAT
What does the RAT FAULT light mean?
It means that the emergency generator is not supplying power when AC 1 + 2 are not powered and the nose landing gear is up.
(A319 - light comes on only if the gen is not powered when AC 1 + 2 are not poeered; independent of gear position)
What does the guarded EMERG GEN P/B do?
In AUTO: this will cause the RAT to extend is airspeed is > 100kts with the nose landing gear in the up position.
Once extended the RAT will couple within 3 seconds providing power as long as speed is not less than approximately 140 kts
A319 RAT works down to 125kts
What does the ELEC RAT MAN ON P/B do?
This will manually extend the RAT and the generator will couple if the nose landing gear is up
What does the TERR p/b FAULT light mean?
A fault is detected in the EGPWS terrain awareness display or terrain clearance floor functions. TAD is computed with captains baro setting and does not have baro setting error protection.
TAD and TCF work on FMGC 1 position.
What does the TERR p/b OFF light mean?
EGPWS functions are disabled
What do the TERR SYS P/B OFF & FAULT lights mean?
OFF: all GPWS warnings are inhibited
FAULT: GPWS malfunction; all warnings are inhibited
What does the G/S, FLAP MODE, LDG FLAP 3 p/b do?
OFF:
- Glideslope EGPWS mode is disabled
- Too low flaps warning is disabled
- too low flaps warning is inhibited when flaps are at 3 for landing
What are the 5 EGPWS modes?
Mode 1: Excessive descent rate “sink rate”
Mode 2: excessive terrain closure “terrain terrain”
Mode 3: altitude loss after takeoff “dont sink”
Mode 4: unsafe terrain clearance “too low flaps”
Mode 5: excessive glideslope deviation “glideslope”
What does the RCDR GND CTL P/B do?
AUTO: the CVR And DFDF are engergised automatically…
- for 5 minutes after aircraft power up
- after an engine is started
- in-flight
- powered for 5 minutes after the last engine is shut down
ON: both CVR and DFDR are energised; the light will extinguish after engine start
What does the CVR erase p/b do?
If the aircraft is on the ground with the park brake set the CVR will be erased
What does the CVR test p/b do?
If held in, with the RCDR GND CTL p/b switched to ON and the parking brake is set, it activates the test; a low frequency tone will be heard over the speakers and a headset if plugged in
What does the oxygen mask p/b do in the auto and man on positions?
In auto the masks will deploy if the cabin altitude exceeds 14,000ft +/- 500 and a pre-recorded message will play in the cabin.
Chemical generators work for 13-15 minutes depending on MSN
In man on the masks will be commanded to deploy but there will be no auto announcement
