an aerodynamic surface providing stability for an aircraft in flight. The stabilizer of an airplane is the fixed or movable leading section of the horizontal empennage. A stationary stabilizer provides stability and has an elevator attached by a hinge to its trailing edge. A movable, controlled stabilizer, which sometimes lacks an elevator, provides both stability and control. Such stabilizers are usually mounted on supersonic airplanes when elevators are not sufficiently effective at high altitudes. The stabilizers of rockets are placed in the tail section and displace the center of pressure of the aerodynamic forces acting on the rocket in atmospheric flight toward the rear of the rocket.
