Which of the following is part of the spin recovery procedure regarding power settings?

The spin recovery procedure emphasizes the importance of reducing power to an idle setting as part of safely recovering from a spin. When an aircraft enters a spin, maintaining or increasing power can exacerbate the situation by increasing the angle of attack, further destabilizing the aircraft. Power reduction to idle helps to decrease lift on the wings and facilitates a more effective response to the recovery actions, which usually involve aileron input to neutral, opposite rudder, and pulling the control yoke or stick forward to break the stall and regain control.

Thus, setting the power to idle is crucial in the spin recovery procedure, as it contributes to minimizing the aircraft's energy state and preparing it for recovery maneuvers.
