Default Emergency Exit

Why not just install a ballistic recovery chute in the glider? That's a lot cleaner solution and saves your butt at a lot lower altitude than bailing out.


Because "just installing" a ballistic recovery chute for a particular airframe takes a very large amount of structural analysis, determination of proper attach points, modification of the fuselage for installation of the rocket extraction system, blow-off panels to allow for chute extraction, actuation cable routing, FAA approvals for certified aircraft or approvals from an IA to determine the feasibility and installation of a system that very few certified aircraft mechanics (IA or A&P) have any familiarity with. This also applies to sailplanes certified as Experimental.

It's not just strapping a pack to your glider. It is WAY more complex and has to be done right.

I started flying hang gliders with a Ballistic Recovery System (BRS) in 1993. I have had two systems from BRS Inc. and one gas propelled unit from (now defunct) Second Chantz. Never had to actually use either one, but I see the advantages for sailplanes. Unfortunately, the mechanics and complex design issues pretty much eliminate practical retrofits to existing airframes..

It is sad that sailplane manufacturers do not seem to be interested in providing the guidance and engineering to incorporate ballistic recovery systems in current designs.

The only glider I know of that has a factory installed BRS system is the TsT-14 Bonus, which operates in the US with a Desert Aerospace installed retractable jet engine capable of self launch and in-flight engine extension and startup. (www.desertaerospace.com)

There may be other sailplanes incorporating ballistic recovery systems, but I have no knowledge of them. If there are others, perhaps RAS participants can offer their input.


I totally agree that retrofitting a BRS system in a glider is a major undertaking. I am baffled why someone like DG would be screwing around with cockpit extraction systems rather than making a BRS system available for their gliders.

One example of a manufacturer who has their act together is the Phoenix Motorglider. It comes standard with a BRS system.
