Trim tab

The center console of a small airplane. The vertical black wheel with spherical bumps is the trim-tab control. Moving it upwards changes the 'hands-off' elevator position to a more nose-down position; moving it downwards does the reverse.
Grave of Buckminster Fuller

Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface.
