A is the most narrow over the shoulders. A or B for girls, C or maybe D for guys. Usually. Older Javelins can be slightly wider over the shoulders even with the same letter.

Thanks for the information. The Astra is not really big in Sweden and it doesn't appear to be anywhere else either. I am not sure why FXC can't get it to be more popular. Maybe it just is not as reliable as a cypres? The Vigil is still quite new so we will have to see. It might be a stronger competitor though. Even though my original thought with this thread was quite unclear, I think I got some good input which did help clarify the issue for me, so thanks everyone.

Derek, I think you mean 0.255 mm. 2.55 mm is correct, a normal loop length is 85 mm or 8.5 cm.

I don't quite understand what it is you are getting at or asking here. Surely you are not suggesting that we should instead just teach RELIANCE on the Cypres??? Please tell me that is not what you are saying. No I am definitely NOT saying that a cypres or any other mechanical device can be trusted. I am also saying that riggers are human, there is no way all reserves in the world now and for ever ever will be completely 100 % safe. I am just saying that there seems to be a discrepancy in what we teach. I never hear anyone saying that a reserve can malfunction to a student. We do stress very hard that a cypres can though. I have also seen students cut away from line twists that were fixable and we tell them if they are not sure cut it away. But what if they cut away something that is landable and get into more truble? As a sideline, of course I trust my reserve, I trust all my packjobs.
-
The point of the post is not to say that an AAD is to be relied on, but a comparison of how we see the reserve as reliable and a cypres as not to be relied on. Would you change the way you teach students if the DZ only used Cypres' and no FXC's?
-
Name one with a cypres or vigil I am not talking about older models.

When we teach students to cut away from a main that they are not sure they can land. This sometimes results in cutting away from something that is quite landable. They will in this case put their trust in the reserve. The reserve however can not be guaranteed to 100%. When we talk about AAD's we say they cannot be trusted, a mechanical devise could fail. But there has been no incident that I know of where a modern AAD has not activated when needed. So they seem to be quite reliable. So, my question is, can we teach our students that using a reserve is always a safe option?
-
Interesting, what about when you are using a running loop? According to Airtec, when a cypres is installed, you are to "Make sure that a Running loop has been installed."

Thanks for all this good information. //r

What type of emergency parachute would you recommend for use in a Twin Otter? It will be intended for all our pilots, of which most do not skydive. They would like it to be thin. Would a round be most common in this application?

This is an answer, from PD, to a question about what to use if I clean my canopy: "Hello Rene, We recommend that you use a Woolite type detergent to wash your canopy. You can wash it in any large tub. You don't want to scrub, just swish around and let soak for awhile. It's best if you have a large place for it to hang and dry. If you have any other questions, please let me know. Thanks, Donna Wagner Customer Service Maintenance and Repair Performance Designs" Notice that there is no mention about avoiding washing altogether. //r

Well the situation was really turbulent and it was a straight in landing. My canopy just kind of stopped flying. It did not respond to flaring. A smaller canopy "might" have had more speed and therefore lift. But of course if you screw up under a smaller canopy you are in more trouble. I think people should be careful with downsizing but if you are wearing 18lbs or more it will put extra stress on you body in a hard landing.

I've been using a belly band ALL SEASON with 10 pounds for 500+ jumps. Had it been a vest my back would have been screwed, honestly I don't notice any physical difference at the end of the day with the lead belly. Anyone had different experiences? Blues, Ian I broke my fibula (or tibula?) wearing about 18 lbs. It can have been the difference between wearing a cast or getting away with it. A lot of other things affected the situation though, like uneven surface, not holding me feet together etc. I do usually wear the weight belt, even on hop and pops and otherwise for fall rate.
-
Yes a resourceful person could probably figure it out but I wouldn't recommend it. If you really want to do it do it under the supervision of a rigger. When you get the bundles of lines and have a canopy in front of you, it is not going to look as easy as one might think. You could probably pack your own reserve too and it could work, but why risk it.
-
I have a friends bungy cord collapsible pilot chute where the old cord is worn out. Does anyone have specs for how much force should be required to stretch it when new? As a rigger would you refit a pc with a new bungy cord or just have them buy a new pilot chute?
-
Thanks the manual there is for a one pin rig and the one I am packing is two pin. I might be able to use something from the racer manual though
-
Yes, I have contacted them. I don't now when to expect an answer but I would like to pack the rig today so there is not much time to wait.
-
Can't find a manual on the internet. Can anyone help me out? There was a series of pictures recently on packing the racer. Maybe those would work? I think I know how to solve the cypres issue but the flaps are not numbered. I think I can see this too but if there are any pictures available that would be nice. (Packing the reserve this is) Thanks, //r

Hi, I have actually seen this type of burr almost wear through the tape. But the owner himself saw it and pointed it out to me asking what to do. It was fixed before it wore through the tape. The reason this could happen is because the pins are punched out from a sheet metal, (thats the way it looks to me at least.) Then they are polished to take away any sharp edges. This pin had a burr left in the opening. The important part is that you need to look at your equipment, not difficult in this case since you do hold the pin in your hand every time you close the rig.

Yet another method to calculate exit seperation
RTB replied to speedy's topic in Safety and Training
Wouldn't less forward throw make the distance larger in this case? I thought belly flyers had less forward throw and FF more penetration into the wind on exit, i.e. more forward throw. //r -
In Sweden we usually don't use packers and keep quite good track of reserve use. The figures last year were: just under 500 tandem per reserve ride ~250 student jumps per reserve 1000 A-D license per reserve. Tandems have longer lines and wear a lot.

Does a main closing loop wear faster on a Throw Out than a Pull Out?
RTB replied to freeflyfree's topic in Gear and Rigging
I just changed mine the other day. It had 200 jumps, didn't look to bad. Not very loose either. Be careful when getting the pullup cord out and check the pin. Should last longer than 10 jumps without a problem. -
For a bit different combinations; lime-navy blue Orange-navy blue lime-turquoise. Maybe turquoise-red White and red is cool also. //r
-
I have a mirage with a freefly handle and I prefer it to a hackey. I'd say try it for a while then decide.

You don't need them to be slippery, friction in the system is actually a good thing. Lessens the force transmitted to the loop.
