Electrical Power Generation
Engine Generators
Primary power is obtained from two engine Integrated Drive Generators. The IDG maintains
a constant generator speed throughout the normal operating range of the engine. An
integral electro–mechanical disconnect device provides for complete mechanical isolation
of the IDG.
APU Generator
The APU generator can supply power to both AC transfer busses on the ground or in flight.
As the only power source, the APU generator can meet electrical power requirements for all
ground conditions and most flight conditions.
External Ground Power
An external AC power receptacle located near the nose gear wheel well, on the lower right
side of the fuselage, allows the use of an external power source. Status lights on a panel
adjacent to the receptacle permit the ground crew to determine if external power is being
used. When connected, external power can supply power to both transfer busses.
