What causes the engine or APU to shut down when the FIRE pushbutton is released?. Fire extinguishing. Thrust reduction. Electrical failure.

What are the roles of the AGENT P/BSW switches in the fire extinguishing system?. Control extinguisher discharge. Monitor avionics equipment. Monitor cabin temperature.

What action is taken on the ground when an APU FIRE warning occurs?. APU is automatically shut down. APU is restarted immediately. APU fire bottles are discharged.

What does the avionics SMOKE detector specifically detect?. Overheating of avionics equipment. Smoke from the lavatories. Smoke from the engines.

How is the cargo compartment smoke detection system monitored?. By the AEVC. By the smoke detectors. By the AGENT P/BSW switches.

how many smoke detectors are installed in each cavity of the cargo compartments. two. one. three.

what triggers the automatic discharge of the fire extinguisher in the lavatory waste bin. presence of smoke. impact with an object. high cabin temperature.

how does the FDU generate a fire warning signal in case of a flame or hot gas detected. opens the ALARM SWITCH. generates a fault signal. sends inert gas.

how many detection loops does the engine fire detection unit FDU have. two. one. three.

what does the FDU do if both loops are broken due to a torching flame?. generates fault warning signal. sends inert gas. shuts down the engine.

in which situations is the detection fault logic based on a dual loop failure activated?. total loss of detection system. both loops working properly. fire on loop B fault on loop A.

what components are responsible for fire detection in the engines and APU. detectors and loop. alarm and integrity switches. FWC and ECAM.

what must be done if an engine or APU LOOP A or LOOP B fault is detected. perform a fire test. shut down the engines. isolate the fault loop.

how does the FDU generate an inoperative signal for loop A or a loop B fault logic. by detecting electrical failure. by detecting core gas. by releasing helium gas.
