Thatīs the system you can buy with some of the newer Schempp - Hirth and
Schleicher gliders.

I am suprised no one has mentioned the Sparrowhawk Glider. Everyone
of the 20
or so sparrowhawks except one has a BRS parachute. The decision was
to go
with a large parachute to REDUCE opening shock. The one is use in
rated for a
900 lb. aircraft. The Sparrowhawk fully loaded with the heaviest
possible pilot would
not even be 500 lbs. I suspect it will come down quite slowly.
Greg Cole fired off the ballistic parachute while it was attached to
the Sparrowhawk.
It was a ground test. He has it on video and it deployed perfectly
with no problems.
The cost is somewhere around $3000.00.

Raspet Labs was using a modified Lighthawk sailplane for testing last
fall, which crashed.

It had a BRS chute which was triggered by the scissoring main spar
when the wings folded, and the pilot was ejected through the cockpit
by the deceleration, I think because the ring that causes slow chute
deployment did not function properly..
Point: the aircraft must be engineered to take the stresses of chute
deployment and the chute must deploy properly. (Nothing is 100% sure
and safe.)
