Abstract
Airplane flight tests have been conducted to determine the effects of wing leading-edge modifications and a ventral fin addition on the spin resistance of a typical high-wing, single-engine, general aviation airplane. Drooped wing leading-edge modifications which improve lateral stability at high angles of attack were tested in combination with a ventral fin that improves directional stability. Each modification was evaluated using spin resistance criteria which have been proposed for incorporation into the Federal Aviation Regulations for certification of light aircraft. The best configuration tested, a combination of outboard wing leading-edge droop and a ventral fin, provided a very significant increase in overall airplane spin resistance, but was not sufficient to satisfy all requirements of the spin resistance criteria.
