Nightingale 0 #1 May 26, 2004 My dad and I were having a conversation today, and he asked me how one packs a parachute. So, I explain. When I got to the stowing brakes thing, he asked me why. I paused and realized I have no clue whatsoever. I was taught to do it, so I do it. So... Why do we stow brakes? Quote Share this post Link to post Share on other sites
FrogNog 1 #2 May 26, 2004 Ram-air canopies open more reliably and consistently if their brakes are held in a certain position (which varies by canopy). -=-=-=-=- Pull. Quote Share this post Link to post Share on other sites
Treejumps 0 #3 May 26, 2004 Setting the brakes slows down the forward speed you have on opeing, reduces the opening "surge", and depending on design, helps promote certain opening characteristics such as speed, heading, and inflation properties. Perhaps Brian G. can elaborate further. At any rate, it should be the goal of every young skydiver to gain a full understanding of all of their equipment. Even if you don't want to rig, take a rigger's course, and you will be amazed at all there is to know. Knowing your gear inside out will make you a more competent and confident skydiver.

Why do we stow brakes? Having the brakes stowed translates to quicker inflation time. There is "less" canopy to pressurize so it will start flying quicker. Im sure it also deals with having the canopy stay under control during and right after the deyployment. Johnny --"This ain't no book club, we're all gonna die!"

With the brakes stowed it opens very consistantly quick and on-heading. Without them stowed it opens slower but more unpredictably - line twists or off-heading openings..

On the risers it had a patch that said "no brake settings on this canopy" or something to that effect. It was something different...
