Thanks for that.

You're welcome.

It would seem therefore that the standard
conical chute is the only choice for the majority of
glider pilots on the grounds that it is likely that
we will only ever use it if we have to.

If by that you mean that you won't train to use your emergency
equipment, then you are correct. Stick with the round. Just don't be
surprised if it lands you in the hospital. Remember - those maximum
loadings are based on a fit man in his 20's wearing boots with ankle
support. For a middle aged man wearing tennis shoes, they really ought
to be reduced by 30% or so. Not so the weights on squares - they are,
if anything, conservative if you know how to land one.

I am firmly of the opinion that people who jump out
of perfectly serviceable aeroplanes are .........how
can I put it.......... lacking in some way. :-)

As opposed to the spectacular good sense exhibited by those who fly
airplanes that don't even have engines
Glass houses, stones, etc.
