What is the maximum airspeed permitted when the gear and/or flaps are extended?

The maximum airspeed allowed when the landing gear and/or flaps are extended in the T-6A is indeed 150 KIAS. This limit is in place to ensure the structural integrity and operational safety of the aircraft while these components are in a deployed position. Extending the gear and flaps alters the aerodynamic characteristics of the aircraft, and exceeding the maximum airspeed could lead to aerodynamic issues, increased drag, or even potential damage to the landing gear or flap system.

Understanding this limit is critical for safe operations, especially during phases of flight where pilots might need to extend flaps or landing gear, such as during approach and landing. Maintaining adherence to this speed ensures that pilots have the control and performance necessary to execute safe maneuvering and landing procedures.
