Could you take the bridal and sew a "loop" on it, like the loops that hold the pins to the bridal, and use this loop to tie your breakcord to? Has any one done this or seen it or thought about it.

I was just wondering.

Thanx

why would you?
there is a proper knot for everything.

yes. i have seen one...

A "short bridle static line" I believe is a term used to describe such contraption.
I have one and it seems to work. Only have 4 jumps on it though, so I don't have extensive experience yet.

You have to be extra careful with the "excess bridle" so you don't step on it and cause premature release.
The way we have used it is that when jumping a buddy of mine has held on to the bridle/pc (almost like PCA) untill the sl has opened the rig.

How far down is the loop from the PC?

Thanx

Only in sub 30m would one need this IMHO. PM for more if you really need it.

everything above 30m is freefall?!

if you have some sharp obsticles near, wouldnt it be safer to hang the PC lower when using the loop ? :)

This topic is not about freefall. But to answer your question, "Yes". I have seen/assisted in sub20m freefalls with specialized gear.

The PC is only there for psychological/convenience benefits in a break cord scenario IMHO.
Be very careful of installing things on the bridle that could inhibit extraction. Fatalities have happened because of this.

just kidding....
cheers

I have a couple bridles like that.

Don't just sew a loop in it, because the loop will pull out. Use another piece of webbing (the same flat webbing that the bridle is made from), lay it flat against the bridle, and tack it down top and bottom. When used for other jumps (non-static line) the extra piece is pretty much invisible and out of the way. When used for static lines, it gives you an attachment point that (if you're careful about the rigging) hardly puts any wear on the actual bridle.

 

The loop in the bridle is about 2m (~6ft) from PC in a 3m bridle.


Thank you for the offer, I appreciate it. If I ever venture to heights that low I will make sure I'll contact you for more information.

In the meantime 'really need' and 'nice to have' are two different things. Of course the view on which jump requires an sl is highly dependent on the jumper. I may consider an object sl jump, even though I regularly see friends freefalling it. For me it is nice to have that extra 2m on any given jump low enough to require sl. That's better for my peace of mind :)

IMHO; Another advantage of the short bridle set-up is a smaller snag force on the break cord upon canopy extraction from the rig. This will lessen the odds for premature release of the attachment. (naturally it is safe to argue, that using a shorter bridle all together would achieve the same)

As Pete already hinted, the bridle was originally constructed to allow PC placement 'somewhere else', other than attached to the object, which often is the case when sl device is routed through the loop in the end of the bridle.

I don't use that bridle for any other jumps. In fact, I have a dedicated bridle for each PC.

Take care and be safe

my wonder is,why not just make a sl bridal?
I mean on my freefall bridal i dont need a extra loop that can snag or catch anything causing hesitasioon or a mal.....

All riggers have bridal material,just make one..
Its not more tough to replace a bridal than to replace a pc..
just a throurght...

In this particular method, does anyone have any suggestions on how to manage the excess bridle between the SL attachment point and PC? Simply s-folding and rubber banding it doesn't seem like too good of an idea because in the event of a premature break cord failure you'd want the full 9' of bridle to keep the "backup" PC out of your burble.

Maybe burble isn't an issue at the low deployment airspeeds of static lining, now that I think about it. Or I'll just stop putting a PC on for SLs

you could attach the excess bridal and pc to the object in a different spot than the static line using a lerks headed rubber band. You'd just have to be sure it will detach cleanly, no hang up points.

Trap the PC (wadded up if necessary) between your body and the object. You can put it between your leg and a handrail, between your back and the object, or just between your knees or ankles (if there isn't a handy part of the object). You'll hold it (and control it) until the moment of exit, when it will fall free behind your body.



At zero airspeed, there is zero burble. The max burble length is approximately twice the width of the falling body (so, at terminal your burble is something like 4 feet long). The burble grows geometrically (with fall rate), rather than arithmetically (with time), so at pre-mature static line break (or go and throw) airspeeds, the burble is negligible.

Yeah. Hold the PC in your hand (just like you were doing a hand-held). When you jump, toss the PC (just like you were doing hand held). The static line will still do its job and the PC will be in clean air (and above the exit point if you pitch right).

Don't bother making a special bridle, just tie a loop in the bridle (as posted above) as close to the container as you can, while still allow for rigging and moving around a bit at the exit point. This allows you adjust the location of the loop based on object requirements.

I have video of me static lining a 137 foot B using this method. It looks like I just went hand held, but the canopy is open way too soon. The pilot chute appears to inflate in clean air just before the canopy bursts open. I, by the way, was open with enough time to clear the (30? 50 foot? I never lasered the tree, though I should have) palm below the exit point and make a 90 right turn to land in the street.

I actually prefer not to hold it in my hand on the remote chance that I slip and fall off the exit point. I worry that in that situation, the normal human instinct is to grab and hold onto anything, and I don't want to come off the exit while clutching my PC by reflex.

Being BASE jumpers, we're not "normal humans."

If I were on a hand held jump and slipped and fell, I hope my first instinct is to get my PC into the air. And I hope I would have the same instinct on the SL. Either way, it's going to be messy and I see your point that if I had a death grip on the PC all the way to the ground it would be very bad.

Just long enough to load the static line and break it prematurely could ruin your day. That would occur around a half second after you fell, less if you end up flailing your arm trying to regain your balance.

Unlikely. The point of tying a loop into your bridle is get the static line as close to your pins as possible. The pins would be pulled long before you could extert force on the SL with panicky deathgrip on your PC.

If anyone reading this doesn't feel comfortable with staying cool under pressure, then please don't use this method. Tie your PC directly to the object with static line, increase your chances of both pre-mature SL breakage as well as PC snag.

If you do use this method, make sure the loop you tie is closer to your pins than your PC and try not to fall until you're ready.

dont fall ;)

Several years ago, I was doing a series of lowish static line jumps, and decided to remove the PC to see if it would help canopy inflation. I didn't really think the PC would do much good in the event of premature break cord failure--there's no way I'd freefall the object--so I asked around to see what others thought.

Dwain pointed out that the most likely time for a premature break cord failure isn't when the container is being opened, but rather when the canopy is being extracted. At that point, he indicated, much of the work has already been done, and it's not really fair to compare it with freefalling the object. It was his feeling, at least, that with an open container and bridle stretch, a PC might actually save your life even from relatively low altitudes.

I've read a lot of our posts here, and have a great deal of respect for your approach to matters like this. I am interested to hear your thoughts.

I´m using 52" with very low static line set up...im also planning to use different lenght of static line set ups to different kind of exits and the loop for the bridle...

in my opinion if the breakcord fails prematurely its better to have something than nothing, and also what i have jumped with that 52" it works fine with my troll 265 MDV:s...flies like an angel ;)

Pöks ja Tsöng and Fu...ck the Finns !! see you on LB on Weekend :)

On a rocket deployed system i helped develop, The rocket opened the rig, started extracting the canopy and then the attachment point separated before line stretch. Bottom skin inflation was at about 16m below jumper exit point. The Jesus jump (27m) in Rio was with a 1m static line and PC (for psychological convenience).
IMHO, If one is doing a breakcord type of jump, 3rd your bridle length.
Hope this helps, PM me if you want more detailed info.
Take care,
