If you look at the use in Cirrus though, that's not the case. It is in the ultralight community but among the larger aircraft the numbers seem to be different probably because under nearly perfect conditions it takes nearly a thousand feet to get the CAPS deployed.Actually, Steve, the BRS useage historically has been at low altitude (500-1000' AGL) to save a pilot during the infamous turn-to-final spin.

There was the case here in Indy (deployed at 528 feet and according to some it did not fully deploy) and the one in Deltona, Florida (both occupants killed; chute deployed immediately prior to impact after spin/stall). The CAPS is not a reliable "out" for a spin/stall scenario at low altitude (<1000') in a standard GA aircraft based on the data currently available. That said, it's a g-dsend in cases where you need it at a higher altitude. There is a reason why I am putting such a system on my designs (although with a compressed gas propulsion system rather than a solid fuel rocket).
