dearching come pull time? Can't Post

I've never heard this said before, and maybe for good reason. Is it good to dearch when youre ready to pull, A) you're slower, B) Somewhat more stable, in a spread body position. Is this wrong? I think this would appeal to pulling, less speed would make for softer opening, stability would cut down on mals. What am I missing?

Arching makes you more stable, that's what I've been taught.

As a student, arching is the best way of being stable. However, it is possible to be stable in any body position you like, "stable" just refers to being in control. Good freeflyers can be stable in head-down for example.

It is important to be stable and belly to earth at pull time, but you don't necessarily need to arch. All students get taught to because that's the best chance they've got of being stable. However, if you can be stable in a de-arch then that's fine too.

Just de-arching won't do that much if you're dumping in place - you're still going to be doing well over 100 mph. But a time when it would be good to de-arch is if you've been doing FS and so have tracked off at the end of it. Then, a good flare out of the track coupled with a de-arch will slow your forward speed right down and is the best way I've found of being stable and down the tube at pull time after I've tracked.

But being in an arch is inheritly more stable (from BTE point of view) than being in a dearch.

An arch is inherently more stable than a de-arch, yeah, which is why that's what students get taught. But it's possible to be just as stable in a de-arch and if you can do that then there's nothing wrong with that either. As long as you provide a stable platform for the parachute to deploy from then no problem.

Edit: but as a student, don't start trying to "see" if you can be stable in a de-arch at pull height!

I know you can be stable dearched, hell I'm stable to 110mph in a dearch (I'm 210 out the door), I'm just going by what the original poster said by

B) Somewhat more stable

I do this but it's not to lose speed but to align my backbone in the event of a hard opening. I have something wrong with a few vertebrae that I have yet to see a doctor about so I'm trying to be careful.

Slowing down before pull time does decrease opening shock, all other things being equal. Remember to not sacrafice stability or pull altitude slowing down to pull.

I have found that a good, quick flare out of a flat track gives me the best openings and the slowest fall rate for pull time.

Well, my body is never really arched... this is why I started freeflying. I hate to arch. So anyway, all of my openings I am flat as hell and falling extremely slow with my f/f suit. I've been doing it since day one so it haven't noticed any difference of course. So, it's obviously possible but has its ups and downs I am sure. Crazy

I've been sitting up at pull time to help with the occaisional slammer opening. I do this right after hitting a hard arch and throwing the pilot chute. My neck can't take many more hard openings......Steve1
