Spins are prohibited when the PCL is set at what power level?

Spins are prohibited when the Power Control Lever (PCL) is set above idle because at this power level, the aircraft's engine output is significantly increased, leading to a higher risk of controlling the aircraft effectively during a spin. When the PCL is above idle, the engine parameters become more critical, and the potential for exceeding performance limits increases. Therefore, conducting spins in this condition may result in uncontrolled flight dynamics, which can be dangerous. Prohibiting spins at this power level ensures that pilots maintain a safer operational envelope and can effectively recover from a spin if necessary.

The prohibition of spins at different power levels serves to ensure safety and control, preventing maneuvers that could jeopardize the flight, especially when engine output is heightened.
