It has been discussed on RAS before, but who manufactures square ram air style bail out chutes for gliders?

I cannot remember the manufacturer's name. But one in particular had comfortable backpack style ram air chutes that did not require a jump certification.

Thanks for any leads.

I used it in my prior LAK-17a and now in my Stemme.

I’m seeing a lot of nonsense rationalization here. Any jump is better experience than no jump at all. If nothing else, you will learn to fly the canopy including judgung the flare on landing. Besides, anything you do in life is first practiced in “ideal� conditions (other than a first kiss!)

Nope, a lot of just-plain-nonsense period.

1) With an emergency chute there is no 'flare on landing'.
Most of these chutes pulling both toggles decreases the effective chute
diameter and increases your sink rate (as explained to me by the chute designer).
DO NOT TRY TO FLARE AN EMERGENCY CHUTE.

2) A practice jump will not be with an emergency round chute.
You will get some practice landing but it will be very different...

3) Ground school will include specifics of how to land,
practice landing jumping of a small platform, etc.
Not to mention the mechanics of chute deployment (ie push, not pull).

Please, go get the ground school.
If you want to take a jump, great, but most important is the ground school.

Hope that helps someone out there,
Best Regards, Dave

All of what Dave said is true, unless you wear a ram-air rectangular
emergency chute.Â* For me training at the sky diving club was a great
improvement over my Air Force training since that was geared to round
chutes and I now have a much more maneuverable square chute.

Dave, what do you mean by "push, not pull" on chute deployment? Assuming
you're talking about rip cord use, I'd advise pull straight down with
both hands, not straight out.

Cheers

It has always been and still is called pulling, throwing for main parachutes, but a reserve pull is technically a push. Straight out is best combination of strength and splitting the difference of direction of cable housing. Cables are always from the top on sport gear varies on emergency rigs.
The few glider static lines I've seen clipped to the reserve handle, which isn't ideal but will work. A lot of pilot rigs cannot be reasonably modified to pull the pin from the back.

There appears to be several schools of thought on egress and deployment of an emergency canopy. Having a plan and rehearsing it regularly is the key, I believe.

I was taught to hold one hand over the D-ring as you egress (if possible) to keep it from flapping around, then grab the D-ring with both hands and punch straight out away from your chest (push/punch vs pull.)

Strong Parachutes has a static line option.

Do round emergency parachutes flare? If there is wind, is flaring even desirable
when you are drifting backwards?

After buying a square parachute, I went with the intention of taking the
ground training (I'd had the Air Force training in the early 70s) and
making one jump.Â* I was scared absolutely ****less, but enjoyed the
actual jump so much that I did 6 more, all solo with instructor aided
deployment.Â* It was expensive, but worth it!

Ground training is one thing, but why not do an actual jump. I went to a parachute school and during the class introductions everyone was asked why they were there. “On a dare, my girlfriend bought this package for my birthday, want to challenge myself“ ... were the usual answers. I said I wear a parachute and I want to know how to use it! I think actually jumping is a confidence booster that will help if and when the time comes. I also think most glider pilots will enjoy it because once the canopy opens, you’re gliding!
