The patent relates to a device whereby providing a parachute canopy with a pull down vent line having predetermined elastic properties, the inflation development time of the parachute can be automatically controlled commensurate with the parachute deployment airspeed. This construction will prevent the accidental development of an excessively deformed drag surface, especially at low air speeds, that can produce wide oscillations of the parachute, causing discomfort and possibly injury to the parachutist upon landing.
