What should be maintained during a controlled descent in the T-6?

During a controlled descent in the T-6, it is essential to maintain speed. The aircraft's performance and handling qualities are closely linked to its airspeed. Maintaining an appropriate speed during a descent allows for better control, ensuring that the aircraft remains within safe operational limits and performs as expected.

Too slow of a speed during a descent can lead to risk of stalling, while too fast can cause issues with control and safety. Therefore, pilots are trained to be vigilant about their airspeed, especially during maneuvers like descents, to ensure they manage the aircraft effectively and safely.

Altitude, heading, and flap configuration, while still important, are secondary focuses during a descent, as the primary objective is to manage speed to ensure stability and control throughout the maneuver.
