The APU standby power system supplies 115-volt ac single phase 400-Hz power to the captain's primary flight and navigation displays and to the left flight management computer.
(14)
With the standby power switch in the auto position and the main battery switch on, the captain's transfer bus normally supplies this voltage.
(15)
If power is lost on the captain's transfer bus, the system automatically switches these loads to the output of the APU static inverter.
