What is the maximum operating speed (Vlo) for landing gear extension?

The maximum operating speed for landing gear extension, commonly referred to as Vlo, must be adhered to in order to ensure safe and efficient operation of the aircraft's landing gear system. In the context of the CRJ 900, the correct maximum operating speed for extending the landing gear is 250 knots. This speed is established to prevent potential issues that could arise from deploying the landing gear at excessive speeds, which can result in structural damage or mechanical failure.

Operating within the specified Vlo ensures that the landing gear can be effectively and safely extended, allowing the pilot to maintain control of the aircraft while transitioning to landing. This limitation is crucial for ensuring the integrity of the landing gear components and for a smooth landing process.
