Setting a hard deck of 1000ft agl is not really of much use. It is

very
unlikely that you would be able to make a successful

abandonment if in
a spin at 1000ft. You should really double that if you are serious

about
having a hard deck which leaves you with another option if the

spin
cannot be stopped. I rejected an abandonment with a control

restriction
in level flight at 1000ft as I was not sure that I had the time. My
parachute was reputed to open and decelerate in time at 750ft

when it
was new.

The reasons why Puchs have spun in is speculative in most

cases. In
most cases the only witnesses worth anything at all, who could

tell you
what happened, couldn't. It is very easy to blame pilots who are

unable
to speak for themselves. As far as I can make out in most cases

the
cause should have been recorded as undetermined. Probably is

just not
good enough.


Don: Cindy said meters not feet.


Sorry I missed that, 1000 metres is a sensible number.
