What is the maximum speed with the landing gear maybe flown extended and locked for CRJ models?

The maximum speed at which the landing gear can be flown extended and locked in CRJ models is 220 knots indicated airspeed (KIAS). This limitation is crucial for ensuring the structural integrity of the landing gear and the aircraft during flight. Exceeding this speed with the landing gear extended can lead to increased aerodynamic drag and potential structural damage to the landing gear assembly or the fuselage. Adhering to this speed limitation helps maintain safe operating conditions and ensures the aircraft performs optimally during various flight phases.
