    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…

    Some aircraft use an inverter power switch to control AC power. Many aircraft simply power the inverter whenever the DC bus is powered and no inverter power switch is needed. On complex aircraft, more than one inverter may be used ... provide a backupAC power source. Many inverters also offer more than one voltage output. Two common voltages found on aircraft inverters are 26VAC and 115VAC. Figure 9-97. Aircraft landing gear schematic while gear is moving to the UP position…

    very useful, especially during cold weather starting. Follow the manufacturer’s recommendations for engine starting using a GPU. The electrical system is turned on or off with a master switch. Turning the master switch to the ON position provides electrical ... energy to all the electrical equipment circuits except the ignition system. Equipment that commonly uses the electrical system for its source of energy includes: • Position lights • Anticollision lights • Landing lights • Taxi lights • Interior cabin lights • Instrument lights • Radio equipment • Turn…
