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…
