ABSTRACT:
An aircraft letdown system is deployable in the event of power failure or mechanical failure over inhospitable terrain or in the event of environmental conditions which preclude VFR or IFR landings. A parachute system, which is attached to the aircraft at a point in approximate vertical alignment with the aircraft center of gravity, is selectively energized by the pilot when it becomes apparent that a safe normal landing cannot be made. On energization, the parachute canopy and the shroud lines are repositioned from the place of storage to a location external to the aircraft and deployed in the conventional manner. To alleviate the shock of landing to the passengers and cargo, a specially constructed impact absorbing landing gear is extended and the occupants are further protected from the landing shock through impact absorbing seats.
