What is the maximum speed for landing gear extension in both CRJ 900 and 700 models?

The maximum speed for landing gear extension for both the CRJ 900 and 700 models is 220 KIAS. This limitation is critical for ensuring the safe operation of the aircraft, as extending the landing gear at speeds higher than 220 KIAS could lead to structural damage or malfunction of the landing gear system. The landing gear is designed to deploy effectively within this speed constraint, ensuring that the aerodynamic forces affecting the aircraft do not compromise the integrity and functionality of the landing gear during this phase of flight. Adhering to this limitation is essential for flight safety and aircraft performance during critical phases such as approach and landing.
