Do your straps up tightly for winch launches!

I guess we just need to secure the shoulder straps properly ? ...

This is somewhat analagous to reported accidents by
Cessna pilots on takeoff; if the adjustable seats
are not properly locked in their rails the seat can
slide backward, making it impossible to push the yoke
forward.

Perhaps we need a two-point attachment for each of
the shoulder straps -- the one above the shoulders
that already is in place and which keeps the body from
being thrown forward, plus a second one from be bottom
of the seat pan, and which would prevent the body from
moving upward and aft. This second strap could also
protect against cranial collision with the canopy.


Anyone for seven-point harness?

Doug,

the reading of an ASI is very rarely connected to winch
launch accidents,
and certainly not in the initial climb.
Sliding back in the seat (or movement of a seatpan)
during initial rotation
has already claimed a number of lives.

them,

accident. Neither am I recommending that you should
connect your instruments up in this way.

No, the area of the openings would not matter, unless
there was a
significant leak.

If your description is correct, then I would not assume
that the
primary cause was the straps, which as you point out
could not be
conclusively determined due to post impact damage.
Can you check the
report again and make sure you have correctly reported
the results?
