How should an aircraft slow down when above 150 KIAS during an engine failure?

In the context of managing an airplane during an engine failure, particularly when the aircraft is above 150 KIAS (Knots Indicated Airspeed), it is crucial to follow guidelines that ensure the aircraft remains controllable and within safe operating parameters.

Selecting to slow to a minimum speed of 125 KIAS is appropriate because this speed allows the pilot to maintain a margin above stall speed while minimizing drag, thus ensuring better control during the critical phase following an engine failure. Operating at this speed promotes a balance between sustaining lift and having sufficient control authority, especially when one engine is non-operational.

Additionally, this speed provides a buffer to accommodate any necessary pilot responses or adjustments needed based on the aircraft's performance characteristics after the failure. By adhering to this recommended speed, the pilot can effectively manage the situation and execute appropriate emergency procedures more efficiently.
