Thanks, yes 3" is not a lot to work with, I guess that is why the Cirrus has those uncomfortable seats installed (they have a high impact seat with little cushion)
The plane for an upside down is to have the regress hammer somewhere in the cockpit (cirrus has them in their middle console), then hit the four corners of the window and hope it will crack and kick out the window.
I have them. I have not crashed yet so can't report on their effectiveness.
I would expect them to be helpful in a hi-G forward deceleration which would not involve the engine coming through the firewall.
That would not help you in a spin or a pancake. In the latter remember that your butt is about 3" above a very solid spar box
which is connected rather securely to the ground.
Also, you need a plan if you land upside down and you manage to survive or for some reason your door won't open.

Hello.….me again
I was reading upon accidents with the Lancair 4p and a few stand out to me, those where the cabin was intact but the pilot died.
So I am reasoning that the energy on impact was just to great to be absorbed and that this was killing the pilot. Now there are Seatbelt airbag now available (AMSAFE), they have them standard in the Cirrus and if I am not mistaken in all new Corvallis as well.
Does anybody from you installed them and what were your experiences?
Thanks — Ronald
