* Exciter-to-igniter plug cable (2)

These components control the operation of the ignition system: * Start/ignition selector

* Fuel control switch

* Airfoil and cowl ice protection system (ACIPS)

* Flap slat electronics unit (FSEU).

The ignition system gets 115v ac power from the electrical load management system (ELMS). The fuel control switch must be in the RUN position to let ELMS supply ignition power to the engine relay unit (ERU). The EEC controls the ERU.   www.aero.cn 航空翻譯 www.aviation.cn 本文鏈接地址:777 AMM 飛機(jī)維護(hù)手冊(cè) 發(fā)動(dòng)機(jī)點(diǎn)火 ENGINE IGNITION PW 777 AIRCRAFT MAINTENANCE MANUAL
