What component controls the landing gear unit in an A320?

• A. Landing gear lever
• B. Steering hand wheel
• C. Rudder pedals
• D. Autobrake system

Answer: (A)

The landing gear lever is the component responsible for controlling the landing gear unit in an A320. When the pilot operates this lever, it sends signals to the landing gear system to either extend or retract the gear, depending on the flight phase. The lever’s functionality is crucial for safe takeoff and landing procedures, allowing for positive control over the landing gear position. This action is vital for ensuring the proper deployment of the gear at landing or its retraction after takeoff, directly impacting the aircraft's aerodynamic performance and safety during these critical flight phases. The other components listed do not play a role in landing gear control; they serve different functions related to aircraft operation. The steering hand wheel is used for controlling ground movements, the rudder pedals are for yaw control during flight, and the autobrake system manages braking upon landing.
