When should power be reduced to 4-6% torque during a Precautionary Emergency Landing?

Power should be reduced to 4-6% torque once within dead engine glide distance of low key position because this action prepares the aircraft for a controlled descent and landing configuration. At this point, the aircraft is at a safe altitude and position to assess landing options while managing energy effectively in the event of an engine failure.

By reducing the power early, the pilot ensures that the aircraft is correctly configured for the glide, optimizing both airspeed and glide path for the expected approach to the runway. This range of torque allows for a stable descent while maintaining control and avoiding excessive speed that could jeopardize the landing.

The dead engine glide distance is critical in determining how much time and space the pilot has to maneuver the aircraft safely to the landing area. Operating at a low power setting aligns with the procedures for managing the aircraft efficiently and enhancing safety during such emergency conditions.
