I was wondering if there was such a thing and if there are any ideas for such a system in the making?

I'm confused. pull out? as in BOC throw out PCs?

I belive he means pull out as in handle connected to bridle so when you pull it pops the pin and the pc is located inside of the container with the pack job like seen on some skydiving rigs.

Hand held is a problem unless you have the option for pull out or throw out.

Arials... not so good. Open the contain while still in the upside down portion of some flippy doos.

Dropped handle...

huge pilot chutes being drug out by the attachment point....

Is there any advantage to this system that makes you want to try it? It seems like it would not lend itself particularly well to a 2 pin system and would delay the time to pilot chute inflation.

You saw more than a few pull outs, mostly Racers, at early Bridge Days. But we knew it would only be a matter of time before someone went in groping for a floating pud. Fortunately their use just went away over time when pure BASE gear became available and we started advocating, at least, BASE pilot chutes and long bridles for everyone.

I did know one fellow that used a pull out system all the time (can't remember his name now) but these were some of the first people doing BASE stowed (when everyone else was going hand held) and he did aerials too. Only since this was about 1987 we didn’t call them aerials, we just called 'em front loops and back loops . . .

The main problem I see with pull outs in modern terms is the pud being attached to the bottom of the pilot chute. In that configuration it inflates fast and gets pulled out of your hand usually before you can fully extend your arm. Large BASE pilot chutes would make that worse. If you don’t let it go right away it will start to barrel roll you. So you are launching it closer to your burble and it could wind up sucked onto your back. Whatever positive container opening characteristics the pull out system has (when you pull the pud you pull the pins) is cancelled out if your pilot chute hesitates.

Plus you can't jump a wingsuit with a pullout.

Yes you can.

you forgot the frown smiley

I guess it's one of those things they don't recommend. Like for some reason they don't recommend jumping airlocked canopies.

That is a new one for me... Can you cite the source of this info? (not that I don't believe ya, just want to learn for myself why.)

Actually, there was an airlock BASE canopy made. I don't think it went into full production, but a friend of mine had one, and it worked fine

 
In CRW we were always dealing with short bridales and burbles. Some people went to pull outs but others had problems with the canopy or bag actualy falling out and hitting there heals. There were also problems with bridales intangaling and cousing problems in the retract. On the other hand jumping really short bridles was a problem. Not enough distance from the burble. One compermise that some people tried was a bottom loaded throw out PC. You would pull it out and it would inflate right there and pull out of your hand. Letting it get a mouth full of air seemed to help a lot to give it the initial pop to pull the pin and it still staged the bridal better then a pull out. The PC was ready to pull when the pin popedand there was less bag tumble issue. It never really cought on. I think one of the reasons was that jumping it with a retract you had to use a handal with a lanyard like a pull out. It was hard to pack it in a way that would keep it from floating. With the handle attached directly at the base of the PC That problem would mostly go away. If the bridal half hitched around the handle then you would still have a fully inflated PC.

Did this proto airlocked canopy also have valves? I would think airlocks might help maintain pressure and some rigidity during very slow or reverse flight.

Negative. The prototype airlocked canopies, which were manufactured by Brian Germaine under contract for Vertigo BASE Outfitters (and, if memory serves, called the "Shaman"), predated the creation of bottom skin valves. They happened at around the same time as the first Vtec canopies from Basic Research, which had uncovered (2 way) valves.

Many people have observed that airlocks combined with bottom skin valves ought to help the canopy maintain pressurization in extreme flight (or strike) conditions. I've talked to a couple people who had wanted to build such a canopy, but nothing has reached the market yet.
