How is external power controlled in the T-6?

In the T-6, external power is controlled primarily through the battery switch. The battery switch allows the pilot to connect or disconnect external power sources to the aircraft’s electrical system. When external power is available and the battery switch is in the appropriate position, it enables the aircraft to use this power instead of relying solely on the aircraft’s batteries. This is crucial for starting the engine and powering the avionics system when ground operations are in progress.

While other options, such as the generator control switch or external power module, are involved in the overall management of electrical power, they do not specifically control the connection to external power in the same direct manner as the battery switch. The circuit breaker system is designed to protect the electrical circuits from overload, rather than controlling the flow of external power. Therefore, these alternatives do not serve the primary function of controlling external power in the T-6 as effectively as the battery switch does.
