How are the landing gear on the T-54A controlled and actuated?

The landing gear on the T-54A is electrically controlled and hydraulically actuated, which means that the initial commands to extend or retract the landing gear are issued through an electrical system. This allows for quick and reliable operation, as electrical signals can travel rapidly throughout the aircraft systems. Once the command is given, hydraulic actuators take over to physically move the landing gear in and out of position.

Using hydraulic actuation is advantageous because it provides the necessary force to maneuver the landing gear reliably under the stress of landing and takeoff. The combination of electrical control for ease of operation and hydraulic actuation for strength optimizes the landing gear function, ensuring safety and efficiency during ground operations.

This configuration is favored in aviation because it allows for a more streamlined design compared to fully mechanical options, while also ensuring that the system can handle heavy loads.
