An automatic spinkler system activates if a fire is detected. There is no built-in fire extinguisher for the lavatories The lavatory fire extinguishing system is activated by a discharge switch on the overhead panel. An aural warning activates and a light illuminates outside the lavatory if smoke is detected. 4 / 15 After a forward cargo fire has been extinguished, what happens when the AFT CARGO FIRE ARM switch is now pushed? The arming functions for the AFT CARGO FIRE ARM switch activate and the metered bottles dicharge into the aft compartment. The arming functions for the AFT CARGO FIRE ARM switch do not activate. The arming functions for the AFT CARGO FIRE ARM switch activate, but discharge into the aft compartment does not occur. 5 / 15 What does the DET FIRE APU EICAS message indicate? APU fire detection is no longer available. A fire has been detected in the APU. The APU fire bottle squibs are inoperative. The APU fire detection system has automatically reconfigured to single loop operation 6 / 15 How many detectors loops does each each engine have and what states may each loop signal? There are three loops. The different possible states are: fire, overheat, and fault. There are two loops. The different possible states are: normal and fault There are two loops. The different possible states are: normal, overheat, fire and fault. There is one loop. The different possible states are: normal, overheat and fault. 7 / 15 On the B777-300, what happens when the CARGO FIRE ARM switch is pushed? It arms all five cargo fire extinguisher bottles. It arms the two rapid dump fire extinguisher bottles. It arms all four cargo fire extinguisher bottles. It arms all six cargo fire extinguisher bottles. 8 / 15 What does the DET FIRE ENG R EICAS message indicate? The fire detection system for this engine has automatically reconfigured to single loop operation. The right engine fire bottle squibs are inoperative. Fire detection for this engine is no longer available. A fire has been detected in the right engine. 9 / 15 What action should you take if the fire switch remains locked after a fire is detected? Push the fire override switch and then pull the fire switch. Pull the fire switch to override the lock. Wait until the fire light extinguishes. Rotate the fire switch. 10 / 15 What happens when an APU fire is detected on the ground and the engines are shut down? The APU shuts down automatically but the fire bottle must be discharged manually The APU does not shut down automatically but the fire bottle discharges automatically The APU shuts down automatically and the fire bottle discharges automatically. The APU does NOT shut down automatically and the fire bottle must be discharged manually. 11 / 15 What happens when an APU fire is detected on the ground and the engines are running? The APU shuts down automatically but the fire bottle must be discharged manually The APU shuts down automatically and the fire bottle discharges automatically. The APU does not shut down automatically but the fire bottle discharges automatically The APU does NOT shut down automatically and the fire bottle must be discharged manually. 12 / 15 During cruise, you notice the OVERHEAT ENG R message displayed on EICAS. What has occured? A fire condition exists in the right engine. An overheat condition exists in the right engine. A pending overheat condition exists in the right engine. Overheat detection in the right detection in the right engine has failed 13 / 15 Engine Fire and Overheat Detection - There are two detector loops in each engine nacelle. Each detector loop provides both fire and overheat detection. Normally, both loops must detect a fire or overheat condition to cause an engine fire warning or overheat caution. False. True. 14 / 15 Which part of the aircraft have fire, overheat or smoke detection systems? Thrust reversers and avionics bay. Engines, APU, main wheel wells, cargo compartments and lavatories. Wings, tailcone, and landing gear. Cockpit, cabin, avionics bay and fuel tanks. 15 / 15 Fire and Overheat Detection System automatically checks for faults in the loops. True. False.
