Which statement best describes the function of the flight control surface interconnect?

• A. Hydraulic pump that powers the actuators.
• B. Electronic feed for navigation.
• C. Mechanical linkages that synchronize surface movement.
• D. Linkage system that coordinates movement of surfaces for consistent control.

Answer: (D)

The flight control surface interconnect is the system that ties together multiple control surfaces so they move in a coordinated, proportional way. When you move the cockpit controls, this interconnect ensures the ailerons, elevator, and rudder deflect in the correct directions and amounts relative to each other, providing a smooth and predictable control response and keeping the airplane from yawing, rolling, or pitching inconsistently during maneuvers. It often uses mechanical linkages, push-pull tubes, cables, or bellcranks, and may be integrated with hydraulic or electronic actuation, but its main job is coordination across surfaces for stable, consistent control. It’s not a hydraulic pump, nor an electronic navigation feed, and while it involves mechanical linkages, the essential idea is the coordinated movement of surfaces to produce the intended overall control effect.
