- Chapter 11: Communication & Navigation › Installation of Aircraft Antenna Systems
Installation of Aircraft Antenna Systems Knowledge of antenna installation and maintenance is especially important as these tasks are performed by the aircraft technician. Antennas take many forms and sizes dependent upon the frequency of the transmitter and receiver to which ... electrically matched to the receiver and transmitter that they serve. They must also be mounted in interference free locations and in areas where signals can be optimally transmitted and received. Antennas must also have the same polarization as the ground…

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…

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…
