In case anyone is curios
here is an interesting presentation by Rick Beach on data regarding the Cirrus BRS system. Rick does NOT represent Cirrus Aircraft. He has made it his mission to look deeply into every Cirrus accident and this has resulted in him being strongly opinionated on the subject. It is an interesting presentation with real world operational data. Some of this has been taken from the data stored by the avionics which on a Cirrus is quite extensive. Since the plane stays pretty much intact after a pull, this data has been recoverable and allowed analysis including deceleration and descent rate in real world use.
