contactor would disconnect the alternator from the bus. Figure 9-82. Schematic GCU control of the exciter field magnetism. Aircraft Electrical Systems Virtually all aircraft contain some form of an electrical system. The most basic aircraft must produce electricity ... operation of the engine’s ignition system. Modern aircraft have complex electrical systems that control almost every aspect of flight. In general, electrical systems can be divided into different categories according to the function of the system. Common systems include…

downstream of the engine-driven fuel pump alerts the crew should fuel pressure decline. Not all large, old aircraft have this fuel system. This is merely an example. Other aircraft share similar features and possess unique features of their ... same is true for small reciprocating-engine aircraft. There are many systems that share features with those described above, but they also differ in some ways. Always consult the manufacturer’s data when working on aircraft fuel systems and follow…

fuel pressure warning lights are also common on jet transport aircraft. The sensors for these are located in the boost pump outlet line. They give an indication of possible boost pump failure. Fuel quantity gauges are important features ... aircraft. Indications exist for all tanks on a transport category aircraft. Often, these use a capacitance type fuel quantity indication system and a fuel totalizer as is discussed later in this chapter. The location of fuel instrumentation varies depending…
