During an engine failure in flight, what is the recommended minimum airspeed to achieve during a zoom/glide?

The recommended minimum airspeed to achieve during a zoom/glide after an engine failure is critical for optimizing performance and maximizing altitude gain as well as distance covered. In this situation, achieving the correct airspeed ensures that the aircraft can maintain the best glide performance, which is crucial for managing the emergency effectively.

The choice of 125 knots represents a generally accepted speed that provides a good balance between maintaining control of the aircraft and ensuring adequate lift. This airspeed minimizes the risk of stalling while allowing for effective maneuvering, which is essential in an emergency descent scenario.

Choosing an airspeed that is too low can lead to a stall, while too high could increase drag and decrease the glide ratio. Therefore, 125 knots is positioned well within the optimal range for many aircraft, offering the best glide performance without compromising safety. This speed aligns with recommended practices in aviation for handling engine-out scenarios.

In determining the preferred airspeed for a zoom/glide maneuver, this value takes into account various aerodynamic factors that allow pilots to optimize the aircraft's efficiency in a critical situation.
