Line twists after your under a good canopy

[SurfFlite 0]

Ok, Since this thread is once again alive let me provide more clarity on what I did and what Omar said.

I initiated an "aggressive" 360 (as in a full toggle pull from slight breaks to down by my thigh very quickly)

3/4 of the way around I was in freefall watching my chute collapsing, as the lines got tight, line twist began.

(at this point cutting away was not on my mind because I was low, IMO)

Omar told me to never to make a snapping quick, aggressive toggle only turn. Not to never make a toggle only turn.

Obviously, a snapping toggle turn IS a no-no. Just read above how many people have done it with the same results I had, some worse. The main reason I posted this in the 1st place was just for the matter that I have never heard or knew this could happen.

iwas checking out my buddies stileeto 170 and i had 3 line twists after a hard right toggle. buddy said it would happen before i went up and part of his explaination was that the canopy was eliptical and it dove faster than my body hence the line twists. even though i was aware of the potetial problem it still scared the hell out out of me. now i keep it in mind everytime i do spirals under canopy. cheers

I have on occasion followed an aggressive toggle turn by an aggressive toggle turn in the other direction.
I knew about flow separation that could make a canopy behave unpredictably or collapse, which I considered a good reason not to do anything drastic under about a 1000', but getting 4-5 line twists seems like a good reason to respect your canopy at any altitude. I have probably been lucky so far because I jump a low wing loading, to compensate for the altitude of the Johannesburg Skydiving Club.

There is a lot of stuff worth doing but then there is a lot of stuff worth doing instead.

I know this was posted early on in the thread, but I just want to re-emphasize the fact......

Collapsing your slider and stowing it behind your head is one really good way to help prevent against self induced line twists. Another good thing is to loosen your chest strap. Doing this shifts the center of gravity from directly above your head where your slider grommets pull your line groups together, to the center of your harness, or at your hips. As your canopy turns it pulls your body into the turn from your hips rather than above your head which flies your body with the canopy more than just dragging it behind.

Another good way to prevent self induced line twists is to be more conservative in your turns. Stilettos are pretty notorious for line twists hence the name "Spinletto's or Spinetto". This is due to the fact that they have a very high rate of turn due to chord length and elliptical design, blah blah. They roll into turns faster than a Sabre or similar canopy. All canopies are suseptible to line twists and its very important to understand the characteristics of your canopy before you try flying it too radically.
