The vertical stabilizer is to provide additional anti torque force to the fuselage once the aircraft has forward motion and airflow across the lifting surface. The design makes use of forward motion and the resulting airflow to create an anti torq...
A stabilator, more frequently all-moving tail, is a fully movable aircraft stabilizer. It serves the usual functions of longitudinal stability, control and stick force requirements otherwise performed by the separate fixed and movable parts of a conventional horizontal stabilizer.owever, such adjustable stabilizers are not the same as stabilators; a stabilator is controlled by the pilot's control yoke (or stick), when an adjustable stabilizer is controlled by the trim system. One example of an airliner with a genuine stabilator used for flight control is the Lockheed L-1011.
