Definition
A flexible tension member made of multiple steel wires twisted into strands, with the strands then twisted around a central core to form a single rope. In aircraft, cable is used to transmit pulling forces in flight control systems, landing gear, trim systems, and engine controls. Aircraft cable is specified by its construction (e.g., 7x19 means seven strands of nineteen wires each) and by its diameter, breaking strength, and material — typically carbon steel or corrosion-resistant steel.
Plain English
A strong, flexible steel rope made of small wires twisted together. On an aircraft, it carries the pulling force from a control in the cockpit to the part it moves, like a rudder or elevator.
Context Anchor
Seen in flight control systems, brake systems, trim systems, and aircraft inspection or maintenance descriptions.
Derivation
From the Late Latin 'capulum,' meaning a rope or halter. The word came into English through Old French 'cable,' originally referring to a heavy rope used on ships. In aviation it kept the idea of a strong rope for pulling, but built from steel wires instead of fiber.
Why Pilots Care
In many aircraft, the yoke, rudder pedals, and trim wheel are connected to the control surfaces by cables. A frayed, stretched, or improperly tensioned cable can cause sluggish controls, binding, or in serious cases a control failure — which is why cable inspection is a routine part of maintenance.
Intuition Check
Do not assume cable means an electrical cord here. In this context, it usually means a flexible metal line that pulls on a control or mechanism.
Example Sentence 1
During the annual inspection, the mechanic checked each control cable for broken wires and proper tension.
Example Sentence 2
A frayed cable was replaced during the annual inspection to maintain full control authority.
