Parachutes fitted on combat or experimental aircraft to reduce the landing run and/or the float after rounding off. They are located in the rear portion of the aircraft and provide a steady deceleration of 0.25 to 0.35 g. They, however, become relatively inefficient at slower forward speeds and are jettisoned either at the end of a landing run or when aircraft has slowed down sufficiently. In some installations, they are automatically retracted at low speeds. Predominantly known as drag chute and tail chute.
