Is the MANUAL starter switch position used under normal circumstances?

The MANUAL starter switch position is not used under normal circumstances because the T-6 aircraft is equipped with an automatic starter system designed to engage and start the engine without pilot intervention. In typical operations, the pilot will utilize the AUTO position, which allows the aircraft’s systems to control the start sequence efficiently and safely.

Selecting the MANUAL position is generally reserved for specific situations, such as when the automatic systems fail or if there is a need to troubleshoot potential issues during the start process. Using manual start can introduce added complexity and risks, as it requires the pilot to manage the start sequence directly, making it less optimal compared to the automatic function. Thus, the automatic starter mode is preferred for regular operations, reinforcing the idea that the MANUAL position is not intended for routine use.
