What does the term 'engine-out procedure' refer to?

The term 'engine-out procedure' specifically refers to a standardized operational protocol designed for situations where an aircraft experiences an engine failure. This procedure outlines the necessary steps a pilot must take to maintain control of the aircraft, ensure the safety of all onboard, and manage the situation effectively.

These protocols are critical because they provide pilots with clear guidance on how to handle engine failure scenarios, including adjusting aircraft configuration, managing airspeed, and selecting suitable landing sites if necessary. It encapsulates a comprehensive approach to maintaining safety and performance in the critical moments following an engine loss.

In contrast, protocols aimed at improving fuel efficiency or conducting routine engine performance checks do not directly relate to emergency situations involving engine failures. Similarly, a procedure for initiating a go-around pertains to landing operations rather than addressing the immediate response required during an engine-out condition. Thus, the focus of the engine-out procedure is specifically geared towards managing engine-related emergencies safely and effectively.
