How is the landing gear extended and retracted?

• A. Electrically commanded and hydraulically activated
• B. Mechanically operated
• C. Electrically operated
• D. Hydraulically activated

Answer: (A)

Landing gear is moved by an electrically commanded hydraulic system. Your cockpit input signals a hydraulic control that directs pressurized fluid to the gear actuators. The hydraulic power actually moves the gear legs in and out, while the electrical signal handles the command and coordination, including locking mechanisms that hold the gear securely in the extended or retracted position. This combination gives the high force needed to overcome the weight and resistance of the gear and doors, with precise control and reliable locking during flight. Purely mechanical or purely electrical schemes don’t provide the same balance of strong actuation and controllable, redundant operation, which is why the electrically commanded hydraulic setup is the standard.
