BRS Aerospace has first invented the first Whole Aircraft Rescue Parachute System (WARPS) in 1980 currently being installed on more than 35,000 aircraft. Today the company offers a wide range of WARPS suitable as retrofits to Cessna series 172 and Cessna 182, as standard installations on Cirrus SR20 and SR22 models but also for installations on LSA and experimental aircraft. A small solid-fuel rocket is used to pull the parachute out from its housing and deploy the canopy fully within seconds. Typically on ultralight installations the rocket is mounted on the parachute container. On larger aircraft installations the rocket may be remotely mounted. The current version, BRS-6. has a separate rocket installation that can be removed from the parachute so that the parachute can be sent for re-packing without the problems of trying to ship the rocket along with it. Typically the parachute requires repacking every six years and the rocket requires replacing every 12 years.
