Definition
A rigid metal linkage that connects a flight control surface (such as an aileron, elevator, or rudder) to the pilot's controls or to a related mechanism such as a balance tab. It transmits movement and force mechanically, so when the pilot moves the control, the rod pushes or pulls the surface to the commanded position.
Plain English
A solid metal rod that physically links the pilot's controls to a moving surface on the wing or tail, so moving the stick or pedals moves the surface.
Context Anchor
Seen in flight control system diagrams and maintenance discussions, especially around balance tabs on elevators, ailerons, or rudders.
Why Pilots Care
Maintains precise, low-play control response so the airplane handles exactly as intended during all phases of flight.
Intuition Check
Do not read “rod” as just any metal stick. Here it means a specific rigid link that transfers control movement between aircraft parts.
Example Sentence 1
When the pilot moved the yoke left, the control surface rod pushed the aileron upward on the right wing.
Example Sentence 2
During preflight the mechanic checked the control surface rod for free movement and proper attachment at both ends.
