What is a bus tie breaker?
A relay that is used to connect/disconnect electrical busses from each other
An over current protection device on an electrical bus
A control device used to turn the generator on and off
A resettable device that opens to prevent damage to electrical wiring
When would external ground power be used to supply electrical power to the aircraft?
When one of the engine driven generators fails in flight
When the aircraft is at the gate awaiting passenger boarding
When the aircraft is being towed from the hangar to the boarding gate
After pushback from the gate, before engine start
When would external ground power be used to supply electrical power to the aircraft?
When the aircraft is still on the ground, taxiing for take-off
In an emergency, when one of the IDGs fails in flight
After pushback from the gate, before engine start
When the aircraft in undergoing maintenance in the hangar
