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…
- Chapter 9: Aircraft Electrical System › Current Limiting Devices › Circuit Breakers
Circuit Breakers A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by an overload or short circuit. Its basic function is to detect a fault condition and immediately discontinue electrical flow ... Unlike a fuse that operates once and then has to be replaced, a circuit breaker can be reset to resume normal operation. All resettable circuit breakers should open the circuit in which they are installed regardless of the position…

aircraft manufacturer’s and instrument manufacturer’s approved maintenance documents should always be consulted for required maintenance and servicing instructions. FAA regulations must also be observed. Figure 10-137. An airspeed indicator makes extensive use of range markings. Altimeter Tests ... Federal Regulations (14 CFR) part 91, section 91.411, requires this test, as well as tests on the pitot-static system and on the automatic pressure altitude reporting system. The certified airframe or A&P mechanic is not qualified to perform…
