How is the landing gear of the CRJ operated?

The landing gear of the CRJ is retractable and operated by an electric hydraulic system, which is essential for the aircraft's aerodynamics and performance during flight. When the gear is retracted during flight, it reduces drag and allows for better fuel efficiency and increased speed. The electric hydraulic system provides the necessary power for the operation of the landing gear, ensuring smooth and reliable deployment and retraction during takeoff and landing. This system is crucial for pilot control, as it allows for immediate responsiveness when the landing gear needs to be maneuvered, contributing to safe aircraft operation.

Other methods such as manual control or a fixed configuration are not used in modern aircraft design like the CRJ, as they would not offer the same level of performance and safety required in commercial aviation.
