What is the proper aircraft configuration when conducting a turning power-on-stall?

The proper configuration for conducting a turning power-on stall involves specific parameters that help simulate the stall conditions effectively and safely. In this case, the configuration involves having the gear and flaps up, which is standard for a power-on stall. The torque setting of 30-60% is necessary because it allows for enough power to be applied during the stall to replicate a scenario where a pilot might find themselves during a climb out or while turning.

Additionally, the required nose-up attitude of 15-40° is critical as it increases the angle of attack, allowing the stall to occur. A bank angle of 20-30° AOB is also used because it introduces a turning component to the stall, which can happen in real-world scenarios where pilots may inadvertently stall the aircraft while attempting a turn.

This combination of parameters reflects safe and effective practice for evaluating the aircraft's behavior and response during a stall, helping to validate the pilot’s ability to recover from such situations. The other choices do not align with the requirements for a turning power-on stall, as they lack the necessary power setting, configuration, or attitude that would effectively demonstrate the stall characteristics of the aircraft.
