How can a jumper keep his feet on the exit when exiting,
it doesnt make any sense.

I can see how your 2 reasons could cause a HD launch
BUT the line above does make some sense to me.

Obviously you can NOT literally leave your feet on the object,
however if the top of your body exits and your legs do not think
it is a good idea and lag behind, well this would give your long
axis a forward rotation in the same way as your 2 causes.

Of course there is a 4th and dreaded cause, your boot is
untied and your buddy is standing on the laces.

i think what they meant by
"keep his feet on exit"
is when a jumper just tumbles forward, and does not actually jump. a sort of BASE fall. where the rest of the body has pretty much fallen down past the feet almost causing a roll. i've seen it. it would be a terrible thing to happen on a cliff, tower, or building. but on the span, where i saw it happen, the jumper just went head down till the pca (csa) opened his canopy. it was ugly. it was his first attempt at BASE (just to clarify).

Ok, despite some fucked up use of english (some of it sounds like 90's management speak), I believe I know what the author is getting at.

Basically, they say that if the jumper leans/ falls forward too far before pushing off the object then his body will already be rotating forwards when he finally leaves. This built in rotation will cause the head low.

Does actually make sense to me.

This is incorrect. I exit this way whenever I'm not able to do a running exit, such as going from a rail. I let my body rotate forward until it's 0 to 30 degrees above the horizon then push out from my legs, or I'll do a hop/dive straight out if I can step up onto the rail. This does not cause me to rotate.

If the jumper pushes off not in line with the center of gravity of their body, they will induce rotation. It doesn't matter what position their body is in. If any rotation occurs on exit, it can easily be countered with movement from the legs.

This is pretty much what I was trying to describe here but I think you said it much better.

g.

well, i was actually talking about a bad jump, or nonjump
but, the article seems to be giving a reason to do a head down, or how to do a head down. the rest of you are describing flat n stable. typical miscommunication.
