The elevator is the primary flight control surface that moves the aircraft around the horizontal or lateral axis.
This causes the nose of the aircraft to pitch up or down.
The elevator is hinged to the trailing edge of the horizontal stabilizer and typically spans most or all of its width.
It is controlled in the cockpit by pushing or pulling the control yoke forward or aft.
Light aircraft use a system of control cables and pulleys or push-pull tubes to transfer cockpit inputs to the movement of the elevator.
High performance and large aircraft typically employ more complex systems. Hydraulic power is commonly used to move the elevator on these aircraft.
On aircraft equipped with fly by wire controls, a combination of electrical and hydraulic power is used.
