What is referred to by the term 'critical engine-out procedure'?

The term 'critical engine-out procedure' specifically refers to the actions and techniques that a pilot employs to maintain control of a multi-engine aircraft following an engine failure. In multi-engine operations, the loss of one engine can significantly affect aircraft control, performance, and handling characteristics.

These procedures typically involve understanding the aircraft's performance limits, recognizing the asymmetrical thrust created by the remaining engine(s), and executing appropriate control inputs to prevent loss of control or excessive bank angles. They also encompass aspects such as adjusting airspeed to the best single-engine climb speed and ensuring that the aircraft is flown in a manner that keeps it stable and responsive.

Proper execution of these procedures is crucial for the safety and efficiency of flight, hence they are an essential area of training for pilots operating multi-engine aircraft. The context of this procedure highlights the necessity for readiness in the event of engine failure, ensuring pilots are equipped to handle such critical situations effectively.
