A single smoke detector.

Correct! Wrong!

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

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

Dual detector channels.

A single detector channel.

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.

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

Immediately discharged.

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

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

Correct! Wrong!

The fire and overheat detection system has:

Automatic fault testing only.

Automatic and manual fault testing.

Manual fault testing only.

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!

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!

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

APU shutdown and after 60 seconds an extinguisher bottle discharge.

APU shutdown and extinguisher bottle discharge.

APU shutdown.

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 or inoperative.

The extinguisher bottle is discharged.

Correct! Wrong!

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 or overheat detection is provided.

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 detection is provided but overheat detection is still available in a degraded mode.

Correct! Wrong!

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

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.

The APU automatically shuts down for a detected fire.

True.

False.

Correct! Wrong!

Cargo compartment fire protection consists of:

Cargo compartment overheat detection, and cargo compartment fire extinguishing.

Cargo compartment smoke detection and cargo compartment fire extinguishing.

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

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 and in the cabin.

The lavatory.

Correct! Wrong!

In addition, the lavatory call light flashes and the master call light at the associated attendant station illuminates. The EICAS advisory message SMOKE LAVATORY is displayed.
