Is emergency flap operation available if the auxiliary battery is the only electrical power source?

The operation of the flaps in the T-6A is directly dependent on certain electrical systems functioning properly. In the case of the auxiliary battery being the only power source, the flap system does not receive sufficient electrical support required for operation. The flap system relies on the main electrical bus in order to function correctly, and without the main battery or other supporting systems active, the auxiliary battery does not have the capacity to operate the flaps.

This limitation is designed to ensure that critical systems receive the necessary power during critical phases of flight or in emergency situations, thus maintaining aircraft safety and operational integrity. Consequently, the correct answer reflects the fact that the flap operation cannot be executed when solely relying on the auxiliary battery.
