QuoteQuoteSide-by-side, cut away the main
Really?
That's not what the PIA dual square report suggests.
They had 11 out of 11 cases of main interference with the reserve when they did that...
I've attached the report.QuoteThanks for that report. I read it carefully. You are wrong. They were talking about the biplane, not the side-by-side. We had a local instructor at another DZ lose his life a few years ago chopping a biplane at low altitude.The main entangled the reserve.
The report did recommend releasing the RSL. I think I'll add that to my emergency procedures. I have the good fortune to be friends with one of the Army test jumpers they talked about in the report. Based on his briefings, our DZ formulated, quite a while ago, the procedures we now teach, and it's worked well. Still, it's good to debate and consider changes from time to time. P.S. We really stress not cutting away the main in a biplane.

This document is a must read on this issue. I just attended Jon La Blanc's lecture on this exact issue based upon person experience and that study.
Please Note: Jon made it clear that this is what he would do, as he is not issuing formal recommendations.
Three main take-aways were:
1) Don't unstow your brakes on either canopy. Steer instead very gently with rear risers.(side by side-don't touch the far right or left risers... use inside rear to nudge the other canopy along, i.e. turn left with the (left) rear riser of the canopy on the right)
2) Don't cutaway from any stable configuration. Just from downplanes.
3) Don't flair at all. You have additional canopy overhead, and can just prepare for your finest PLF.
I can't cover his whole lecture here nor do I have that permission. But, if you can attend at any safety day he gives anexcellent review. Including reserve size issues, etc...
Please Note: He made it clear that this is what he would do, as he is not issuing formal recommendations.
