At what speed should the landing gear emergency extension procedure be initiated?

The correct speed to initiate the landing gear emergency extension procedure is 110 knots. This speed is typically specified in the aircraft's operating handbook or emergency procedures section to ensure that the aircraft is within a safe operating range during the extension process. Initiating the emergency procedure at this speed helps to prevent potential issues such as excessive aerodynamic forces acting on the landing gear or the aircraft becoming unstable during the maneuver. Selecting the correct speed is crucial for maintaining control and ensuring the safety of the operation, especially in an emergency situation.
