What gear configuration provides the stall speed of 70 KIAS in the T-6A?

In the T-6A, the clean configuration refers to the aircraft being in a state where the landing gear is retracted, and flaps are also not extended. This configuration allows the aircraft to achieve a lower stall speed due to reduced drag, which is particularly important in various phases of flight, especially when operating at higher speeds or in a clean aerodynamic state.

The stall speed of 70 KIAS is specifically associated with this clean configuration because, in this state, the aircraft maintains optimal aerodynamic efficiency and performance characteristics that result in the specified stall speed. In other configurations, such as landing or gear down with flaps extended, the stall speed would be higher due to the increased drag and altered aerodynamic characteristics.

Thus, the correct answer highlights how stall speeds are influenced by aircraft configuration and emphasizes the significance of understanding these operational limits for safe maneuvering and performance assessments in flight.
