Section 10. Electrical
10.7 Abnormal Procedures
10.7.1 One Generator Inoperative
A loss of a generator prompts a load shed of the air conditioning system and the bus
tie contactor to automatically close so the opposite generator powers the entire
airplane and charges both batteries. When engines are running, an inoperative
generator causes a L (R) GEN OFFLINE caution message to appear.
NOTE:
The BUS TIE switch must be in the AUTO position for this to occur.
If an in-flight engine restart is required, it is accomplished using the operating
generator and the start battery. A process similar to ground start takes place in which
the aft buses are isolated from the forward buses, with the forward buses being
powered by the system battery.
10.7.2 Both Generators Inoperative
With both generators inoperative in flight, the aircraft is operating on battery power
only and a BATTERY POWER ONLY warning message appears. The ACS will shed
all electrical loads that are not required for continued safe flight and landing. The
systems battery and start battery have sufficient capacity to power the remaining
(emergency) loads for at least 30 minutes.
For engine start when both generators inoperative, the start battery powers the
starter/generator for the engine being started. The systems battery powers those
loads on the forward busses required for continued safe flight and landing. A fully
charged start battery allows at least three start attempts.
10.7.3 Load Shedding
The ACS automatically sheds non-essential loads that cause overload of the
remaining operating generator.
