What is the recommended airspeed when experiencing an engine failure after Vr?

When experiencing an engine failure after reaching the takeoff decision speed (Vr), the recommended airspeed is crucial for successful aircraft control and safe recovery. The range of 65-70 KIAS is optimal for maintaining control of the aircraft while maximizing performance during a critical phase of flight.

This airspeed range allows the pilot to achieve a minimum safe airspeed necessary for maintaining control while also enabling the aircraft to climb at a reasonable rate if conditions allow. The specific speed range aids in managing the aircraft's performance characteristics, like stall speed, while ensuring adequate handling especially when maneuvering or adjusting for any drift due to adverse conditions, such as wind or turbulence.

Flying at a lower airspeed could lead to a stall, particularly in a situation where the aircraft's performance is already compromised due to the loss of engine thrust. Conversely, flying at a higher recommended airspeed could hinder performance, waste fuel, or complicate emergency landing maneuvers in tight situations. Hence, the choice of 65-70 KIAS is well-founded in aviation safety protocols for engine-out scenarios during takeoff.
