Which of the following IS NOT procedurally correct when conducting the power-off-stall (ELP stall) maneuver starting ABOVE 150KIAS?

The process for conducting a power-off stall, particularly from a speed above 150 KIAS, involves several key steps to ensure the maneuver is completed correctly and safely. After completing the THREE C's (climb, configuration, and checklist), reducing the power to 4-6% torque is a procedural step that might not be appropriate when starting from above 150 KIAS. This is because such a power reduction may not be sufficient to initiate a proper descent, especially when transitioning from a high-speed environment.

Engaging in a gradual power reduction allows for controlled deceleration and ensures that the aircraft is configured appropriately for a glide. A reduction to only 4-6% torque can lead to insufficient energy management, which may cause a rushed maneuver or an unforeseen stall onset without adequate airspeed and altitude management.

The remaining steps, such as decelerating towards best glide speed, establishing a glide at 125 KIAS with a vertical speed indicator (VSI) of 1350-1500 fpm, and rolling wings level immediately after completing the THREE C’s, are fundamentally sound for carrying out the power-off stall. These steps ensure that the aircraft is correctly configured and within the appropriate flight parameters to safely execute the stall maneuver.
