All statments are correct.

SMOKE red light on CARGO SMOKE overhead panel turns off when there is no more smoke.

Correct! Wrong!

APU Fire - The presence of the red disc on the left side of the aircraft fuselage indicates:

A red disk, which is outside at the rear of the fuselage, signals that the agent is not discharged overboard due to bottle overpressure.

The pilot must check the indicator for the second APU bottle on right side of the fuselage.

The APU fire extinguishing bottle has experienced an overpressure discharge.

Correct! Wrong!

If a smoke has been detected in one of the lavatories:

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

DISCH light illuminates.

ENG FIRE p/b illuminates red.

Correct! Wrong!

Engine fire protection is provided by 2 detection loops which provide informations to a computer (FDU). Which statement about these loops is right?

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

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

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

Correct! Wrong!

The avionics smoke warning triggers, if:

Both smoke detectors detect smoke for more than 5 s, or one smoke detector detects smoke for more than 5 s, and the other smoke detector is inoperative.

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

Both smoke detectors detect smoke for more than 5 s, or one smoke detector detects smoke for more than 10 s.

Correct! Wrong!

The fire protection system provides:

Smoke detection and extinguishing for cargo compartments and waste bins.

Fire detection and extinguishing for the avionics compartment.

Portable fire extinguishers for engines and APU.

Correct! Wrong!

"DISCH" comes on amber when the corresponding fire extinguisher bottle has lost pressure.

False

True

Correct! Wrong!

On the CARGO SMOKE overhead Panel, when does SQUIB illuminate white?
