What type of power does the starter/generator provide?

The starter/generator in the T-6B plays a crucial dual role, primarily providing power for starting the engine and then converting to a generator to supply electricity for the aircraft's systems once the engine is running. When the engine is cranked, the starter function engages to help initiate engine operation. Once the engine is successfully started, the system shifts to generator mode to deliver primary electrical power for various aircraft components and systems, such as avionics, lighting, and other electrical loads.

This capability is essential as it ensures that the aircraft has a reliable source of power for operational functionality while in flight. Additionally, it simplifies the electrical architecture of the aircraft by integrating both starting and generating functions into a single unit. Thus, the starter/generator indeed supplies primary aircraft power, which is critical for normal operations.
