Fault Lights Flashcards
What does steady illumination of the amber IR FAULT light indicate?
The respective IR is lost.
What does flashing of the amber IR FAULT light indicate?
Attitude and Heading information may be recovered in ATT mode (you have lost the navigation portion).
What does the amber ADR FAULT light indicate?
A fault is detected in the Air Data Reference system.
What does the red FAULT light on the RAT & EMER GEN pb indicate?
Emergency generator is not supplying power when AC bus 1&2 are not powered, also during the 8 second
RAT extention
What does the SMOKE light in the GEN 1 LINE pb indicates?
Smoke detected in the avionics ventilation ducting.
Will there be any other indications of avionics smoke?
ECAM warning and amber FAULT lights in the EXTRACT and BLOWER pbs on the VENTILATION
panel.
What does an amber FAULT light in the SYS pb indicate on the GPWS panel? Is the terrain mode
affected?
Any failure of GPWS mode 1 through 5, NO terrain mode is not affected.
What does an amber FAULT light in the TERR pb indicate on the GPWS panel?
Predictive mode fail, terrain is not shown on the ND.
What does an amber FAULT light in the APU MASTER SW pb indicates?
An APU auto shutdown has occurred.
What does an amber FAULT light in the APU BLEED pb mean?
APU bleed leak
What does a FAULT light in the ENG ANTI ICE pb indicate?
Switch- valve disagreement
What does a fault light in the wing anti ice pushbutton indicate
• Low pressure is detected
• Switch- valve disagreement
Note: The amber FAULT light comes on briefly as the valves transit.
What does an amber FAULT light in the MODE SEL pb indicate?
Both automatic pressure controllers are faulty.
What would cause amber PACK FAULT light to illuminate?
• Pack outlet overheat
• Compressor outlet overheat
• Switch position disagreement with pack flow control valve
Note: FAULT light will be illuminated during preflight as no bleed air is supplied.
What does the amber FAULT light in the APU BLEED pb indicate?
Bleed leak (APU bleed valve closes)
What causes the amber FAULT light on the ENG BLEED pb?
- Bleed valve is not closed during Engine start
- Bleed valve is not closed with APU bleed on
- Overpressure downstream of the bleed valve.
- Overheat
- Leak (wing or engine leak on the related side)
What does the amber HOT AIR FAULT light indicate?
• Duct overheat is detected (The Hot Air and Trim Air valves will close automatically).
What does the amber FAULT light in the (GALY &CAB) pb indicate?
The load on any generator is more than 100% of rated output.
What does a FAULT on the ENG GEN pb indicate?
- The associated generator control unit (GCU) trips it.
* The generator line contactor is open (switch is not selected off).
When is it normal to see the ENG GEN FAULT light illuminated?
Prior to engine start
What does the APU GEN FAULT light indicate?
- The associated generator control unit (GCU) trips it.
* The generator line contactor is open (switch is not selected off).
When is the APU GEN FAULT light inhibited?
- APU speed too low
* Line contactor OPEN after EXT PWR or ENG Generator takes over
What does an IDG FAULT light indicate? When is it inhibited?
- Oil pressure low (inhibited when N2 < 14%)
- Oil outlet temperature overheat
- Light is inhibited when IDG is disconnected
What does a BAT FAULT light indicate?
Battery charging current is outside limits (An indication that battery is faulty).
What will cause a FUEL MODE SEL PB FAULT light?
Center tank has more than 250 kg and either wing tank has less than 5000 kg.
What does an amber FAULT light in the FUEL PUMP pb indicate?
Fuel delivery pressure drops.
If the FAULT light in the PTU pb is ON, are there any other indications on the HYD Panel?
Yes – also a FAULT light illuminated in the respective ENG PUMP pb
What does an amber FAULT light in the PTU pb indicate
Overtemp in reservoir
• Low air pressure in the reservoir
• Low quantity in the reservoir
What does an amber FAULT light in the ENG PUMP pb indicate

What does a FAULT light in the BLUE or YELLOW ELEC PUMP pb indicate
- Pump pressure low
- Overtemp in reservoir
- Low air pressure in the reservoir
- Low quantity in the reservoir
- Overheat in the pump
What does the CARGO HEAT HOT AIR amber FAULT light indicate?
Duct overheat
What does the CARGO HEAT AFT ISOL VALVE amber FAULT light indicate?
Valve disagreement of inlet or outlet valve
What does the red SMOKE light in the FWD or AFT pb indicate?

With 2 FAULT lights on the VENTILATION panel are there any other indications?
Yes – The SMOKE light in the GEN 1 LINE pb.
What does a fault light on the ENG panel indicate?
- Auto Start Abort
* Switch disagreement between HP valve and it’s commanded position
