Definition#
A trim tab is a small, adjustable surface attached to the trailing edge of a primary control surface (elevator, rudder, or aileron). When adjusted, it creates an aerodynamic force that holds the main control surface in position.
Why It Matters Operationally#
Trim tabs eliminate the need for constant pilot pressure on the controls, reducing fatigue during long flights and allowing hands-free flight in stable conditions.
