Definition
A mechanical flight control system in which the pilot's control inputs are transmitted to the flight control surfaces through steel cables routed over pulleys, fairleads, and bellcranks. Movement of the yoke, stick, or rudder pedals pulls the cables, which in turn move the ailerons, elevator, and rudder. The pulleys guide the cables around bends in the routing without binding, while turnbuckles maintain proper cable tension.
Plain English
It's the system of steel wires and small wheels inside the airplane that connect the pilot's controls to the moving surfaces on the wings and tail. When you move the yoke or pedals, you're physically pulling cables that run over little wheels and through the airplane to move the control surfaces.
Context Anchor
Seen in flight control, preflight inspection, and maintenance discussions, especially when checking for smooth control movement or unusual stiffness.
Why Pilots Care
These components must remain properly tensioned and free of wear to ensure responsive aircraft handling; binding or failure can result in loss of control authority.
Analogy
Think of an old hand-pulled bicycle brake. Squeezing the lever pulls a cable that runs along the frame and routes through small guides to reach the brake. A control cable system in an airplane works the same way, just with more cables and pulleys reaching to the wings and tail.
Intuition Check
Do not read “cables” here as electrical wires. In this context, the cables are mechanical parts that physically pull on the airplane’s control system.
Example Sentence 1
During preflight, the pilot moved the yoke through its full range to confirm the control cables and pulleys were operating freely and the ailerons and elevator responded correctly.
Example Sentence 2
After maintenance the mechanic verified that the control cables and pulleys moved smoothly when the yoke was turned.
