At what maximum airspeed should landing gear be extended?

The maximum airspeed for extending the landing gear is 150 KIAS (Knots Indicated Airspeed). This limit is established to ensure the integrity and safe operation of the landing gear mechanism during deployment. Extending the landing gear at or below this airspeed helps prevent excessive aerodynamic forces that could potentially damage the gear or the aircraft.

Beyond this speed, the airflow and pressure can be significant enough to create challenges in the gear's deployment, including possible structural stress or failure. It is critical for pilots to adhere to this airspeed limit during the landing gear extension process to maintain safety and operational efficiency. The specified limit is part of the aircraft's operational guidelines and is designed to protect both the aircraft and its occupants during landing procedures.
