G550 - Fire Protection

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 aft cabin

Underneath the front cabin.

In the tail compartment.

Correct! Wrong!

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

False

True.

Correct! Wrong!

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

In the lavatories only.

In the cabin and in the baggage compartment.

In the baggage compartment.

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.

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

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

In the nose landing gear wheel well

In the right main 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 APU fire extinguishing system uses:

The aircraft engine’s number 1 bottle

Its own dedicated bottle

The aircraft engine’s number 2 bottle

One or two of its own dedicated bottles.

Correct! Wrong!

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

When the left fire bottle is discharged.

All statements are correct.

Any time the bottle pressure is low

Only when the capsule is depressed.

Correct! Wrong!

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.

True.

False.

Correct! Wrong!

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

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

False

True

Correct! Wrong!

How would you know that a bottle had thermally discharged?

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

By checking the pressure gauge indication on the bottle

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

You would not.

Correct! Wrong!
