What is the entry power setting recommended for a power on stall?

The recommended entry power setting for a power on stall in the T-6A is typically between 30-60% torque. This range is optimal because it allows for sufficient thrust to maintain controlled flight while also ensuring that the aircraft experiences the aerodynamic conditions necessary for a stall.

When performing a power on stall, the goal is to simulate the power and trajectory dynamics that might occur during a normal climb or takeoff where the aircraft could stall due to an excessive angle of attack. The 30-60% torque range strikes a balance between having enough power to get into the stall without being overly aggressive, which could mask stall characteristics or lead to an artificially high stall speed.

Using lower settings, like in the first option, might not provide enough thrust, leading to potential uncommanded descents or difficulties in recovering. In contrast, higher settings like 70-90% torque would push the aircraft beyond its normal operational limits for this maneuver, increasing the risk of overstressing the airframe or leading to stall characteristics that are not representative of typical operations.
