New Static line set up?
http://www.baserigging.com/...mp-static-line-stas/

Curious if anyone has a good reason to use a contraption like this?

Re: [Huck] New Static line set up?
wow, someone must've been very bored.

edit to ask, furthermore, do people really pay 5.00 € for closing loops?! Shocked

From the guy making it.

- The pilot chute is protected (it do not takes the wind and do not go into your legs or the object)
- The absorber (blue part) decreased the risk of premature rupture
- A better pressurization of the pilot chute with a start in the right direction

ya... someone is real bored and had lots of rigging problems.

Re: [Huck] New Static line set up?
Wow. Talk about unnecessary complexity and cost. It's basically just a way of managing the PC during a static line, or at least that's how it looks to me.

I'd love to see one of those systems in person, but I'm not willing to pay the 200 euros to see it.

It also appears to rely on tying the break cord directly to the object, which is the major issue that most carry on systems are designed to avoid.

Re: [Huck] New Static line set up?
why does one a pc for sl jump, it is only psy if you think about it. tcs

Re: [base283] New Static line set up?

I read somewhere that DW suggested keeping the PC
on during S/L jumps, not to open the rig but to help
get your pack job to line stretch . . .

I keep a PC on because the benefit out weighs the cost,
however it is usually an older PC and I keep it controlled
with a large elastic.

Re: [base283] New Static line set up?
I agrree.
Advantages: canopy flies much better. Less snag points. No floating pc (if that bothers you...)

Cons: i havent found one yet. Except you have to tie two knots at exit, boom there is one.

Re: [Huck] New Static line set up?
I don't have as much trust in a carry with you system (break cord portion) as I do a Pilot chute. Its all single point failure, but if you break a static line prematurely with no pilot chute on, for the next 2 seconds your going to feel like an idiot.

Re: [try2live] New Static line set up?
the STAS? lol.
looks more like some of the torture/whipping/lashing devices that i fantasize about involving a smoking hot dominatrix with big ol' titties
Shortcut
Re: [try2live] New Static line set up?
i think the main causes for premature breakage would negate the help of a PC anyway, likely you'll still feel stupid for another 2 seconds while towing your perfectly working PC to impact.

the stuff i static line typically will not give you much (if any) chance of canopy by PC alone. i double check, and trust my rigging.

that being said, i've never taken the PC off, because that's just extra work, but i've never had an issue managing it.

i love low static lines. super fun stuff. Smile

Who said anything about a single point? My system is redundant.

If you use a single attachment and no pc.... see BFL.


edit: Imho 15 secs of work for a canopy that flys 10% better is worth it.

I have seen someone prematurely break their static line from a 180'E if it wasn't for them having a pilot chute they wouldn't be breathing today.

no doubt. but, 180' is high (relatively) as it is totally free-fallable. i'm talking 80-150ft where static lines or direct bags are probably the only good option.

what caused the break?

Re: [roostnureye] New Static line set up?
Sounds like a single tie off.....

Watch this video from Apex from about the 3:30 mark.

They show that just five pounds falling the full length of a nine foot bridle can shock-load 80lb break cord enough to break it - even if they tie two different sized loops for redundancy.

Therefore it seems to me like there is at least a possibility that you could fall the nine feet to bridle stretch, easily pop your carefully primed pins, and then have your ~10 pound canopy shock load the break-cord and disconnect you from the object before you've achieved line stretch.

So let's say this scenario occurs on a 120 foot jump.

At this point in time you are in freefall exactly 111 feet from impact, your canopy is still more or less in your pack tray, and the only thing at full extension is your bridle.

Now in this scenario would you rather have an inflated 46 inch pilot chute at the end of your extended bridle, or would you still prefer to squeeze a little more performance out of your lightly loaded F111 seven-cell?

Re: [Huck] New Static line set up?
Sorry. Didn't mean to assume you use that particular form of redundancy.

But no matter what sort of redundancy you use, I still think that there is significant potential for high forces on the break cord due to shock loading, and that makes things way too unpredictable for me to not use a pilot chute at all.

all good.

Since we are showing our work!

Thats why it's so important to only use the smallest amount of bridle from your bottom pin to where you tie the knot/static line setup Smile.

Re: [Zebu] New Static line set up?
What? Doesn't everybody tie their static line knot six inches or less from the pin? Crazy

Few years ago a Brazilian guy died from a SL jump without PC (check BFL #118). :-(
