In the event of an APU fire test, a red APU FIRE message is displayed. A red APU FIRE DETECTOR FAIL message appears for a failure of the detector when the system is tested.

False.

True.

Correct! Wrong!

An amber APU FIRE DETECTOR FAIL message appears for a failure of the detector when the system is tested.

How would you know that a bottle had thermally discharged?

You would not.

L or R FIRE BOTTLE DISCHARGE red message would display on the CAS.

By checking the pressure gauge indication on the bottle

L or R FIRE BOTTLE DISCHARGE amber message would display on the CAS.

Correct! Wrong!

An APU fire warning speaker is externally mounted _____ in order to alert ground personnel to an APU fire during ground operations.

In the right main landing gear wheel well

At the aft of the fuselage (near the APU).

In the nose landing gear wheel well

In the left main landing gear wheel well

Correct! Wrong!

This speaker is used only when the aircraft is on the ground.

The FAULT DETECTION TEST procedure checks the system fire detection control unit for faulty circuitry, not for fire loop continuity.

True.

False

Correct! Wrong!

The APU fire extinguishing system uses:

The aircraft engine’s number 2 bottle

Its own dedicated bottle

One or two of its own dedicated bottles.

The aircraft engine’s number 1 bottle

Correct! Wrong!

The engine fire-extinguishing system consists of two identical, single-shot fire-extinguishing bottles containing a fire-extinguishing agent and propellant, mounted:

In the main wheel well area.

Underneath the front cabin.

In the tail compartment.

Underneath the aft cabin

Correct! Wrong!

The smoke detection system is made up of a photoelectric smoke detector:

In the cabin and in the baggage compartment.

In the baggage compartment.

In the lavatories only.

Correct! Wrong!

The galley and lavatories may also contain smoke detectors. The exact location of the smoke detectors is determined by the agency that installs them, because they are not part of the production aircraft.

When will the legend in the APU fire extinguisher switch be illuminated?

Any time the bottle pressure is low

All statements are correct.

When the left fire bottle is discharged.

Only when the capsule is depressed.

Correct! Wrong!

Loss of the helium in the APU fire detector loop causes a CAS message to annunciate the failure.

True

False
