What is the first step to take following an engine failure in flight?

The first step following an engine failure in flight is to pitch for best glide. This action is crucial because it helps to maintain the optimal airspeed for the aircraft while maximizing the distance it can cover. By achieving and maintaining the best glide speed, the pilot can ensure that the aircraft remains controllable and has a greater chance of reaching a suitable landing area, thereby increasing the chances of a successful outcome in a critical situation.

Focusing on achieving best glide also allows the pilot to assess the situation calmly and gather information about potential landing options. Maintaining control of the aircraft is a priority during an engine failure, and optimizing altitude and airspeed is essential to achieve that control.

Other actions such as checking the fuel gauge, communicating with ATC, or attempting an immediate restart are important, but they come after ensuring the aircraft is in a stable state with best glide established. Each of those actions requires time and situational awareness, which are best managed when the aircraft is flying optimally.
