Definition
Rigid metal tubes used in an airplane's flight control system to transmit pilot inputs from the cockpit controls to the control surfaces. They push and pull as the pilot moves the yoke, stick, or rudder pedals, mechanically actuating the ailerons, elevator, or rudder.
Plain English
Stiff metal rods that connect the controls in the cockpit to the moving parts on the wings and tail. When you move the yoke or pedals, these rods push or pull to make the control surfaces move.
Context Anchor
Seen in discussions of airplane flight control systems, preflight inspections, and how pilot control inputs reach the control surfaces during flight.
Why Pilots Care
They provide precise, direct control response; wear, bends, or misalignment can cause sluggish handling or loss of control authority.
Intuition Check
Control tubes are not tubes that carry air or fluid. In this context, they are rigid mechanical links that carry motion from one part of the control system to another.
Example Sentence 1
When the pilot pushes forward on the yoke, control tubes transmit that movement back to the elevator, causing the nose to drop.
Example Sentence 2
The mechanic adjusted the rod ends on the control tubes to restore proper aileron travel.
