This seems to be at odds with a recent edict by the
BGA who have banned the use of carbon fibre and kevlar
instrument panels because of the danger when they break.
Both materials break with sharp jagged edges they say.

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?
