Airbus A350 - Fire Protection

APU FIRE - On ground, if the FPF detects a fire:

The APU automatically shuts down, and the external horn sounds

The APU automatically shuts down, the FPS arms automatically the squibs on each fire extinguisher, and the external horn sounds

The APU automatically shuts down, the FPS arms automatically the squibs on the fire extinguisher, and the external horn sounds

Correct! Wrong!

LAVATORY SMOKE DETECTION - If the SDF detects smoke in any lavatory:

The Flight Attendant Panel (FAP) displays an associated cabin smoke alert and there is an intermittent horn sound next to the lavatory.

The SMOKE LAVATORY SMOKE ECAM alert is triggered, and the Flight Attendant Panel (FAP) displays an associated cabin smoke alert.

The Flight Attendant Panel (FAP) displays an associated cabin smoke alert.

Correct! Wrong!

APU FIRE - On ground, if a fire is detected, the Fire Protection System (FPS) automatically activates the extinguishing system.

False.

True.

Correct! Wrong!

CARGO COMPARTMENT PROTECTION - The Smoke Detection System (SDS) has smoke detectors in the forward and aft/bulk cargo compartments. These detectors are in cavities within the ceiling panels. Each cargo compartment cavity has _____ detectors.

Four.

Two.

Three.

Correct! Wrong!

AVIONICS BAY SMOKE DETECTION - The SMOKE L(R) AVNCS SMOKE alert is triggered if, in the left(right) avionics ventilation circuit:

Both detectors detect smoke or one detector detects smoke and the other is failed.

One or both detectors detect smoke or one detector detects smoke and the other is failed.

Both detectors detect smoke or one detector detects smoke and the other is failed.

Correct! Wrong!

MAIN LANDING GEAR FIRE PROTECTION - The Fire Protection System (FPS) detects overheat in the MLG bay.

True.

False

Correct! Wrong!

The FPS uses two identical loops (A and B) for each sensitive zone. The FPF receives information from the two loops. The FPF provides information to the ECAM to generate applicable fire warnings or loop cautions.

The avionics bay has a Smoke Detection System (SDS) and a Fire Detection System (FDS).

False.

True.

Correct! Wrong!

Each avionics ventilation circuit has two smoke detectors. They are in the air extraction ducts.

CARGO COMPARTMENT PROTECTION - The Smoke Detection System (SDS) uses detectors that are in cavities within the ceiling panels. There are:

5 cavities (A350-900) or 6 cavities (A350-1000) in the forward cargo compartment, 5 cavities (A350-900) or 6 cavities (A350-1000) in the aft/bulk cargo compartment, one of which is in the bulk cargo compartment.

5 cavities (A350-1000) or 4 cavities (A350-900) in the forward cargo compartment, 5 cavities (A350-1000) or 4 cavities (A350-900) in the aft/bulk cargo compartment, one of which is in the bulk cargo compartment.

5 cavities in the forward cargo compartment, and another 5 cavities in the aft/bulk cargo compartment, one of which is in the bulk cargo compartment.

Correct! Wrong!

CARGO COMPARTMENT PROTECTION - When the flight crew presses the assigned push-button, the extinguisher agent is released into the affected cargo compartment. A diverter valve directs extinguisher agent to either the forward or aft/bulk cargo compartment.

False.

True.

Correct! Wrong!

ENGINE FIRE DETECTION - The Fire Protection System (FPS) uses two identical loops (A and B) to monitor the sensitive zones. What are they?

The sensitive zones of the engines are the fan compartment, the intermediate compressor compartment, the core compartment - Pylon.

The sensitive zones of the engines are the fan compartment and the intermediate compressor compartment.

The sensitive zones of the engines are the fan and the turbine compartments

Correct! Wrong!

These zones are protected, because they are heat sensitive zones in which a fire could potentially start.

Can the flight crew press the ENGINE FIRE p/b in the case of an engine tailpipe fire?

Only if the APU bleed is available.

No. This would cut the FADEC power supply.

Yes, but this must be coordinated with the ground staff.

Correct! Wrong!

CARGO COMPARTMENT PROTECTION - If smoke is detected in a cargo compartment, the ventilation:

will stop after 60 seconds.

Will stop when the agent is discharged

Automatically stops.

Correct! Wrong!

WASTEBIN FIRE EXTINGUISHING - The wastebin in each lavatory has a built-in, automatic, fire extinguishing system.

True.

False.

Correct! Wrong!

AVIONICS BAY SMOKE DETECTION - The "SMOKE L(R) AVNCS DET FAULT" alert is triggered if one or both detectors fail in the left(right) avionics ventilation circuit.

False.

True.

Correct! Wrong!

APU FIRE - The Fire Protection System (FPS) uses:

Two different loops (A and B). Each loop has a similar fire detector.

Two identical loops (A and B). Each loop has a fire detector.

One loop with two fire detectors (1 and 2).

Correct! Wrong!

The Fire Protection Function (FPF) receives information from the two loops. The FPF provides information to the ECAM to generate applicable fire warnings or loop cautions.

WASTEBIN FIRE EXTINGUISHING - The wastebin in each lavatory has:

A built-in, automatic, fire extinguishing system.

A built-in, automatic or manual fire extinguishing system. The detection is activated from the Cabin attendant FAP.

A built-in, fire extinguishing system. The detection is activated from the Cabin attendant FAP.

Correct! Wrong!
