What is the first step in the engine failure emergency procedure?

Establishing the best glide speed is crucial in the event of an engine failure because it maximizes the distance that can be traveled while gliding. This speed allows the aircraft to achieve the most efficient aerodynamic performance and provides the pilot with the best chance of locating a suitable landing area. Maintaining this speed during a glide not only enhances control over the aircraft, but it also helps in managing altitude and distance, which are critical factors when preparing for an emergency landing.

In an engine failure scenario, the immediate priority is to maintain control of the aircraft and manage the glide to find an appropriate landing area. While notifying ATC, performing a fuel check, and preparing for an emergency landing are important steps, they can only be effectively executed after ensuring that the airplane is flying in a controlled manner at the optimal glide speed. Thus, establishing the best glide speed should be the first action a pilot takes during this emergency.
