What conditions exist while a pilot is depressing the MSW?

When a pilot depresses the MSW (Master Switch), it typically results in the disengagement of the autopilot, which means the aircraft will no longer be automatically controlled by the autopilot system. Additionally, in many aircraft, this action can also deactivate or render all trim systems inoperative. This is significant because it places the control of the aircraft entirely in the hands of the pilot, requiring them to manage the aircraft manually without the assistance of autopilots or trims, which are vital for maintaining stability and control.

The conditions that arise when the MSW is depressed are crucial for understanding manual flight operations, as the pilot must be prepared to handle the aircraft without the automated systems they may have relied on. This aspect of flight training emphasizes the pilot's ability to take direct control, especially in situations where automation is disengaged for safety or operational reasons. Evaluating this understanding helps in preparing pilots to handle various flight situations effectively.
