Boeing 777 Engines Boeing 777 Engines 1 / 15 What is auto-relight? Auto-relight provides hung start protection by deactivating the ignitor. Auto-relight provides flameout protection by activating the autostart system. Auto-relight opens the start valve automatically if the engine fails to start. Auto-relight provides flameout protection by activating both ignitors. 2 / 15 Can Thrust over-boost occur in EEC Alternate mode when the thrust levers are in full forward position? yes no 3 / 15 With auto start ON, when do you move the FUEL CONTROL switch to RUN? After reaching maximum motoring speed. After START has been selected on the START/IGNITION selector. After the engine stabilizes at idle. After 18% N2 has been reached. 4 / 15 What malfunction, during ground start, will cause the autostart system to abort the start? Broken fanblade. High oil pressure. Hot start. Low oil pressure. 5 / 15 What does the ENG REV LIMITED L EICAS message mean? The left engine reverser will not deploy or will be limited to idle. The left engine reverser is limited to 1 hydraulic source. Engine reverse thrust is limited to the left engine. The left engine reverse thrust is limited to ground operation only. 6 / 15 The EGT indication has a maximum continuous limit represented by a red band. False. True. The EGT indication has a maximum continuous limit represented by an amber band. The maximum continuous limit does not apply during takeoff or go–around. 7 / 15 The autostart system does not monitor engine oil pressure but it monitors engine temperature. True. False. The autostart system does not monitor oil pressure and temperature. 8 / 15 What powers the left engine thrust reverser? Center hydraulic system. Left engine bleed air. Left hydraulic system. Right engine bleed air. 9 / 15 When does automatic continuous ignition activate? When flaps are out of the UP position or engine anti-ice is on. When the thrust levers reach idle or the landing gear is down. When thunderstorms are detected on the weather radar. When the landing gear is down. 10 / 15 Which engine parameters the does the auto-start system not monitor and abort the start sequence? Starter shaft failure.Hung start. Hung start. Oil pressure and temperature. No N1 rotations. 11 / 15 Engine oil pressure is high. Validate The fuel/oil heat exchanger valve is not functioning. The engine fuiel valve on the left engine is closed. Both the spar and the engine fuel valves on the left engine are commanded to the same position. The spar or engine fuel valve on the left engine has not reached its commanded position. 12 / 15 What does the ENG OIL TEMP L EICAS message mean? Engine oil pressure is low. Engine oil pressure is high. Engine oil temperature is high. Engine oil temperature is low. 13 / 15 If the required signals are not available to operate in the normal mode, the EEC automatically uses the alternate mode. In the alternate mode, the EEC schedules N1 as a function of thrust lever position. False. True. 14 / 15 The oil system provides pressurized oil to lubricate and cool the engine main bearings, gears and accessory drives. The oil system also provides automatic fuel heating for fuel system icing protection. False. True. 15 / 15 The EICAS caution message ENG FAIL (L or R) is displayed if an engine unexpectedly decelerates to less than idle speed. False. True. Your score is By Wordpress Quiz plugin
