Check out the Cirrus website for their research and incorporation of the BRS.
 Very well done and tested IMHO.   www.cirrusdesigns.com

There are undeniably some situations where a BRS would be the descent option
of choice:  night loss of power into dark country, most mountainous terrain,
water landings, various IMC scenarios.

There is one other system that would help greatly in theses situations but it does 
not have enough terrain detail to allow a dead stick landing and that is a 3D 
topographical moving map. http://www.free-flt.com/ 
At least it would allow you to parachute down in a valley and not on 
top of a mountain.
