  • Chapter 7: Aircraft Systems › Electrical System

    Electrical System Most aircraft are equipped with either a 14- or a 28-volt direct current (DC) electrical system. A basic aircraft electrical system consists of the following components: Alternator/generator Battery Master/battery switch • Alternator/generator switch • Bus bar, fuses, and circuit ... breakers • Voltage regulator • Ammeter/loadmeter • Associated electrical wiring Engine-driven alternators or generators supply electric current to the electrical system. They also maintain a sufficient electrical charge in the battery. Electrical energy stored in a battery provides a source of electrical…

  • Chapter 3: Aircraft Construction › Subcomponents

    Subcomponents The subcomponents of an airplane include the airframe, electrical system, flight controls, and brakes. The airframe is the basic structure of an aircraft and is designed to withstand all aerodynamic forces, as well as the stresses imposed ... weight of the fuel, crew, and payload. The primary function of an aircraft electrical system is to generate, regulate, and distribute electrical power throughout the aircraft. There are several different power sources on aircraft to power the aircraft electrical systems…

    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 for operation ... 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 lighting, engine starting…
