the horizontal airfoil of an aircraft's tail assembly that is fixed and to which the elevator is hinged

a small lifting surface located behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed wing aircraft such as helicopter s and gyroplane s

a small wing that provides positive or negative lift to stabilize the aircraft in flight

Main horizontal tail surface

Usually synonymous with Stabilator (q.v.).

The fixed horizontal tail surface.

The horizontal airfoil surface of the tail unit that provides stability along the length of an aircraft. The tailplane may be fixed or adjustable.

A tailplane, also known as horizontal stabilizer, is a small lifting surface located behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed wing aircraft such as helicopters and gyroplanes. However, not all fixed-wing aircraft have tailplanes, such as those configured with canards (where the "tail-plane" is located in front), flying-wing aircraft, where there is no tail, and v-tail aircraft where the fin/rudder and tail-plane are combined to form two diagonal surfaces in a V layout.
