Aircraft stabilizers and other tailplane components
In aerodynamics, vertical and horizontal fins that prevent erratic rolling (see roll) and pitching (pitch), respectively. Stabilizers are usually placed together in the form of a tailplane. Like the wings, the horizontal fins have an airfoil shape and can provide lift at take-off. In flight, however, they act only as stabilizers and in some designs the air thrust on them acts downward. In marine engineering, fins or tanks are used to keep a submarine or ship steady in rough seas.
