Airbus A330 - Fire Protection

Which of the following statements is true?

Each engine and the APU are equipped with a fire and overheat detection, and extinguishing system.

Engine fire protection is provided by 2 detection loops which provide information to a computer (Fire Detection Unit).

If both loops break and breaks occur more than 5 seconds apart, a fire indication is generated.

If both loops are working, both loops must sense a certain temperature to generate a fire indication.

If both loops are working and one loop senses a certain temperature, a fire indication is generated.

Correct! Wrong!

What does an amber ECAM warning SMOKE DET FAULT mean?

Both SDCU (Smoke Detection Control Units) channels fault or loss of all smoke detections.

Engines smoke detection is not available.

Avionics smoke detection is lost.

Correct! Wrong!

What does this SMOKE light indicate?

Smoke or fire is detected underneath the cockpit in the electronics and avionics bay.

Correct! Wrong!

A red disk, which is outside at the rear of the fuselage, signals that:

The APU extinguishing bottle has experienced technical fault but it is still available.

Correct! Wrong!

Each lavatory is equipped with:

One heat sensor.

Two smoke detectors.

One smoke detector.

Correct! Wrong!

Three sensing elements in the APU compartment.

One sensing element in the APU compartment.

Two sensing elements in the APU compartment.

Correct! Wrong!

When a sensing element is subjected to heat, it sends a signal to the fire detection unit. As soon as loops A and B detect temperature at a preset level, it triggers the fire warning system.

If the APU fire system detects a fire in flight will the extinguisher discharge automatically?

No.

Yes.

Correct! Wrong!

The avionics smoke warning triggers, if both smoke detectors detect smoke for:

More than 10 seconds, or one smoke detector detects smoke for more than 15 seconds, and the other smoke detector is inoperative.

More than 5 seconds, or one smoke detector detects smoke for more than 10 seconds, and the other smoke detector is inoperative.

More than 5 seconds, or one smoke detector detects smoke for more than 5 seconds, and the other smoke detector is inoperative.

Correct! Wrong!

When an APU fire is detected on ground, the APU fire light on the External Power Control panel comes on. In addition:

A horn sounds, APU must be shut down using APU shut off switch on External Power Control panel.

A horn sounds, APU Auto shut down occurs, and the APU fire extinguisher bottle is automatically discharged.

A horn sounds, APU auto shut down occurs, pilot must discharge fire bottle.

Correct! Wrong!

A fire has been detected on engine 1. ENG 1 FIRE pb and FIRE light on ENG 1 MASTER will extinguish:

When the ENG 1 MASTER is selected to OFF.

When the ENG 1 FIRE pb is pressed and released.

When the fire on engine 1 no longer exists.

Correct! Wrong!

If the ENG FIRE pb is depressed:

Fuel HP Valve is closed.

Both Fuel HP and LP Valves are closed.

Fuel LP Valve is closed.

Correct! Wrong!

Smoke has been detected in the AFT cargo compartment. The pilot has pushed the AFT AGENT pb and bottle 1 has discharged. The bottle 2:

Will discharge all its contents immediatly after bottle 1.

Will automatically discharge its contents over a period of 260 minutes.

Is now held in reserve to fight a fire in the FWD compartment.

Correct! Wrong!

On CARGO SMOKE overhead panel, SQUIB illuminates white:

When both bottles are empty.

When both FWD AGENT and AFT AGENT pb are pushed.

Only during cargo smoke test.

Correct! Wrong!

There is an automatic and manual fire extinguishing system in the wastebin of each lavatory.

True.

False.

Correct! Wrong!

There is only an automatic fire extinguishing system in the wastebin of each lavatory.

When smoke is detected in the avionics compartment:

Cabin fans are automatically stopped.

FWD AGENT SMOKE pb on the CARGO SMOKE panel illuminates red.

AVNCS SMOKE on VENTILATION panel illuminates red.

Correct! Wrong!

Cargo fire protection is provided by:

Automatic smoke detection, manual fire extinguishing.

Automatic smoke detection, automatic fire extinguishing.

Automatic fire detection, automatic fire extinguishing.

Correct! Wrong!

If the system detects an APU fire while the aircraft is on the ground, it shuts down the APU automatically and discharges extinguishing agent.

True.

False.

Correct! Wrong!

What is the true statement about the fire extinguishing system?

There is one bottle for each engine.

There is one bottle per cargo compartment.

There are two bottles per engine.

Correct! Wrong!

If smoke has been detected in one of the lavatories:

ECAM message SMOKE LAVATORY SMOKE appears in the cockpit and cabin crew is automatically alerted.

Waste fire extinguisher is automatically triggered.

Lavatory ventilation is automatically cut off.

Correct! Wrong!

The engines and the APU each have a fire and overheat detection system consisting of two identical gas detection loops (A and B) mounted in parallel and a Fire Detection Unit (FDU).

False.

True.

Correct! Wrong!

Each engine has two extinguisher bottles equipped with electrically-operated squibs to discharge their agents. Each squib has a single electric supply.

True.

False.

Correct! Wrong!

The smoke detection system of the cargo compartments consists of smoke detectors, that are housed in:

Pairs in cavities within the cargo compartment ceiling panels.

Cavities within the cargo compartment walls.

Cavities within the cargo compartment floors.

Correct! Wrong!

There are 2 cavities in the forward cargo compartment, 2 cavities in the aft cargo compartment and 1 cavity in the bulk cargo compartment.

What does an amber ECAM warning ENG 1 FIRE DET FAULT mean?

It is not possible to fight a fire in engine 1.

Both loops in the engine fire detection system have failed.

One loop in the engine fire detection system has failed.

Correct! Wrong!

When the cargo smoke warning triggers, each isolation valve of the cargo ventilation system of all compartments close automatically, and the extraction fan stops.

True.

False.

Correct! Wrong!

When the cargo smoke warning triggers, the isolation valves of the cargo ventilation system of the affected compartment close automatically, and the extraction fan stops.
