18
Q

Describe the generator bus electrical distribution.

A
  1. The generator powers the FCP GEN BUS
  2. The FCP GEN BUS powers the RCP GEN BUS and the FCP AVI BUS
  3. The FCP AVI BUS powers the RCP AVI BUS
19
Q

What happens if the BUS TIE fails?

A

The battery and generator buses become isolated and only feed power to their respective equipment.

20
Q

What supplies the primary power for the T-6A?

A

The generator, located in the accesory gearbox

21
Q

Which side of the cockpit contains the circuit breakers for the battery bus?

A

The left console panel

22
Q

What is the purpose for the auxiliary battery?

A

It provides power for a minimum number of aircraft systems in the event of the generator and primary battery failing.

23
Q

Within the Battery Bus circuit, what does the HOT BAT BUS provide?

A

It provides continuous power to essential components that are either require continous operation or are needed in the event of an emergency.

24
Q

What is the GCU and what is its purpose?

A

The Generator Control Unit. The GCU providesvoltage regulation, over/undervoltage protection, and generator overload protection.

25
Q

In order to use external power, what switch must be flipped on for it to work?

A

They battery switch, BAT, because the external power is distributed throughout the battery bus.
