On the ground with both engines off an APU fire signal from either APU fire detector loop causes:

APU shutdown.

APU shutdown and after 60 seconds an extinguisher bottle discharge.

APU shutdown and extinguisher bottle discharge.

Correct! Wrong!

There are ______fire extinguisher bottles are installed for cargo compartment fire extinguishing. Pushing the FWD or AFT CARGO FIRE ARM switch (ARMED visible) arms the extinguishers.

Seven.

Six.

Five.

Correct! Wrong!

The main gear wheel wells has two distinct fire detection and fire extinguishing systems.

False.

True.

Correct! Wrong!

The bulk cargo compartment is not included in the AFT cargo fire detection and extinguishing systems.

False.

True.

Correct! Wrong!

The bulk cargo compartment is included in the AFT cargo fire detection and extinguishing systems.

There are multiple dual-channel detector assemblies in each engine nacelle. Each detector channel provides both fire and overheat detection. If a fault is detected in one channel, the remaining channel element automatically switches to single channel operation.

If both main engine detector elements on a single assembly are faulted, no fire detection is provided but overheat detection is still available in a degraded mode.

If both main engine detector elements on a single assembly are faulted, no fire detection is provided but overheat detection is still available.

If both main engine detector elements on a single assembly are faulted, no fire or overheat detection is provided.

Correct! Wrong!

The EICAS advisory message DET FIRE ENG (L or R) is displayed if the engine fire detection system fails.

Lavatory Fire Extinguishing

Extinguisher operation is automatic.

Extinguisher operation is normally automatic, but it can also be initiated from the flight deck.

Extinguisher operation is normally automatic, but it can also be initiated from the cabin.

Correct! Wrong!

There is no flight deck indication.

Cargo compartment fire protection consists of:

Cargo compartment smoke detection and cargo compartment fire extinguishing.

Cargo compartment smoke detection, cargo compartment overheat detection, and cargo compartment fire extinguishing.

Cargo compartment overheat detection, and cargo compartment fire extinguishing.

Correct! Wrong!

The main wheel well fire and overheat detection system consists of:

Dual detector channels.

A single detector channel.

A single detector channel for the fire detection system and another single detector channel for the overheat detection system.

Correct! Wrong!

The APU automatically shuts down for a detected fire.

False.

True.

Correct! Wrong!

APU Fire Extinguishing - During an n APU fire signal and after the APU is shutdown, the APU extinguisher bottle is:

Automatically discharged after a 10 second delay to allow time for the APU inlet door to close.

Immediately discharged.

Automatically discharged after a 15 second delay to allow time for the fuel valve to close.

Correct! Wrong!

APU Bottle Discharge (APU BTL DISCH) Light – If illuminated amber:

The extinguisher bottle is discharged or has low pressure.

The extinguisher bottle is discharged.

The extinguisher bottle is discharged or inoperative.

Correct! Wrong!

The fire and overheat detection system has:

Automatic fault testing only.

Manual fault testing only.

Automatic and manual fault testing.

Correct! Wrong!

Turbine overheat detection is provided in addition to engine fire and engine overheat detection. A turbine overheat event is annunciated with the same flight deck indications as an engine overheat (OVERHEAT ENG L, R).

True.

False.

Correct! Wrong!

Lavatory Fire Extinguishing - Each lavatory has two fire extinguisher bottles. Each bottle discharges through two nozzles into the waste container.

True.

False.

Correct! Wrong!

Each lavatory has only one fire extinguisher bottle. The bottle discharges through two nozzles into the waste container.

Each lavatory is equipped with:

A dual channel smoke and fire detector.

A single smoke detector and a dual channel fire detector.

A single smoke detector.

Correct! Wrong!

If smoke is detected in a lavatory, an aural alert sounds in:

The flight deck, the lavatory and in the cabin.

The lavatory.

The lavatory and in the cabin.
