The anti-servo tab is most closely associated with which control surface?

The anti-servo tab is primarily associated with the stabilator, which is a type of tail control surface that combines the functions of the elevator and the horizontal stabilizer into a single movable surface. The purpose of the anti-servo tab is to increase control surface stability and prevent overcontrolling, especially at higher speeds.

When a stabilator is deflected, the potential for excessive movement is heightened, which could lead to loss of control. The anti-servo tab moves in the same direction as the stabilator, providing aerodynamic resistance that enhances the pilot's ability to make precise maneuvers and helps make the control feel heavier. This additional resistance is particularly useful during approach and landing phases, where fine control is essential.

In contrast, while the other control surfaces like elevators, ailerons, and rudders may have their own specific configurations or features, they do not utilize an anti-servo tab in the same context as stabilators do. Thus, the relationship between the anti-servo tab and the stabilator is unique and critical for enhancing control effectiveness.
