I think that the ASW-24 and -28 (maybe the -27 as well) are built with a
kevlar layer in the cockpit. It does not improve strenght, but provides
splinter protection when the cockpit shatters. Fiberglass when broken is
extremely sharp, so the kevlar makes the shell stay together and not
splinter.
I may be wrong, so anyone with more knowledge feel free to correct me!

Good flights (winters almost over...)

After seeing first hand the eggshell strength properties
of glass cockpits when they hit objects, I have been
thinking about how much protection I don't have between
my spine and terra-firma.

I have the astronaut foam, and otherwise it is just
the seatpan and glass. I was chatting with my A+P
about this while we had the seatpan out during my annual.

Has anyone contemplated and/or added kevlar to their
cockpits? Or is this just a nutty idea? I assume
their would be a weight and balance issue, and also
determining if the layup would in fact to any good.
Comments?
