What should be done with the power control lever (PCL) if recovering from an incipient spin?

Setting the power control lever (PCL) to idle when recovering from an incipient spin is critical for effective spin recovery. In this situation, reducing power helps to minimize any additional aerodynamic effects that can exacerbate the spin. When the PCL is at idle, it reduces the thrust produced by the engine, which decreases the torque effect that can contribute to the spinning motion.

Furthermore, during a spin recovery maneuver, the primary focus is on reducing the angle of attack and applying the appropriate control inputs to return the aircraft to controlled flight. By setting the PCL to idle, the pilot is better positioned to manage the aircraft's flight path without the added complication of engine thrust potentially increasing the spin rate.

While other options might seem like viable strategies in different scenarios, they do not align with the proper procedures for spin recovery in the T-6B. For instance, maintaining maximum power would increase torque and complicate recovery efforts, whereas adjusting to cruise power settings may not provide the immediate responsiveness needed during this critical phase of flight.
