EAGLE DYNAMICS

Electrical System

The electrical system is a 24-volt, direct-current (DC) system which provides power for operating the

various aircraft systems, controls, and lighting equipment. The system employs the aircraft's metallic

structure as a common ground return.

The electrical system runs off the battery until the engine reaches 1500-1700 RPM, when the

generator is cut in by the voltage regulator. The battery charge and power for the electrical system is

then supplied by the generator. An external battery receptacle is mounted on the right side of the

fuselage at the trailing edge flap.

Figure 25: Electrical Control Panel

To prevent any damage to the electrical system from overload, circuit breakers are used. These

eliminate the use of fuses and allow for the possibility of replacing broken circuits in mid-flight.

The circuit breaker reset buttons are on the Electrical Control panel. All of the buttons can be reset at

once by means of a vertical "bump" plate that covers all of the switches. The ammeter gauge is also

located on the Electrical Control panel. The ammeter indicates how much current is flowing from the

generator and also shows whether or not the generator has cut in at 1500-1700 RPM as it should.
