Puchaz spin - now wearing 'chutes

The whole ship chute concept is a bit of a worry. There you are in a
large heavy object with absolutely no control. With a personal chute
you do have steering on most rigs nowadays.

With a whole ship chute would it just ruin your day to have save and
then hit the high voltage lines, fall out of a tree, fall over a cliff
etc?

Actually, Mike, on that we disagree.

Unless you are using a square canopy for your personal chute, you have
very little choice on where you are gonna land...and hitting the tree,
high voltage lines or over the cliff are gonna suck less if you have
some aluminum or fiberglass around you. Well, that was my decision for
sure.

Oh, and keep in mind that as I disagree with you, I do it with all due
deference to someone as distinguished in our sport as yourself (no
sarcasm, I meant that!)

OK, crank these numbers. Consider my Nimbus 2C (Experimental, so I could
install a BRS) at 650 Kilos with water (which takes 5 minutes to dump). The
gear strut will give 30mm on impact and the tire will give 50mm more. The
cockpit shell is just fiberglass with no crush structure.

I pop a BRS at 300 meters AGL with the surface wind at 15 knots. What are
my chances? Give BRS weights, 'chute diameters and descent rates.
