The pin doesn’t go through even the big housing. The big housing is needed for the eye on the steel cable. But you k ow that. This is one of my dislikes of the system. The pin can act as a ripcord stop if it doesn't rotate out of the eye. If you're old enough to remember why ripcord stops were bad in the 70's you'll understand. I'm old for my age.

I don’t supposed PCA/USPA records exist of ASO, Area Saftey Officer 220? I was ine starting in 1983 until they became S&TA. I'm old for my age. Terry Urban D-8631 FAA DPRE

Your survey and under lying assumptions are flawed. Find an experienced master rigger willing to talk to you and learn aa little first. I'm old for my age. Terry Urban D-8631 FAA DPRE

video! I'd be more worried about towing it forever than hard opening. I guess I shouldn't have an opinion. I never jumped ropes and rings. I would but too fat to land the things at 240#. But going downward. My goal is to lose enough weight to jump the rounds I want to jump, RW PC and UT-15. I'm old for my age. Terry Urban D-8631 FAA DPRE

There are things that are worth doing for fun, but jumpimg a ramair without a slider is not one of them. Not worth the risk. Get it open, have fun flying it, but skip the drama of rooes and rings if it still has them. I'm old for my age. Terry Urban D-8631 FAA DPRE

Pretty sure Dan only. I know Dan but have never asked. But the story that came back to his home DZ (mine) was that is was used in the tow boat barge industry in the NW. When the company that owned the rights found out what Dan was doing with it (skydiving) they said no more. We had a bunch around here since Dan moved from here to buy Paraphernalia and we all knew him. But I can't find one for nothing. I'm old for my age. Terry Urban D-8631 FAA DPRE

Maybe more Cirrus Cloud size. I still have mine. I'm old for my age. Terry Urban D-8631 FAA DPRE

You can also add a ring that requires no sewing on the riser. Ring on a loop of small webbing larks headed onto bottom of riser where riser large ring goes through. This is Ray Farrell's field approval for a RSL on anything. Value of this? Back when we had risers break no matter where they broke this ring would be left behind and not fire RSL.

Can't see it very well but I think its a chrysalis. Used by Paraphernaila on Northern Lite before Northern Lite was sold to Velocity Sports. I'm old for my age. Terry Urban D-8631 FAA DPRE

Rigging a main is a job for a rigger. And in this case a rigger experienced with rounds. That being said no, you do not want to use slinks because there are more lines on a round. PC's also have very heavy center lines which pull down the apex and take quite a bit of load. The best will be L bar links. If you don't know what L bar links are it means you probably don't know enough to rig this. Put on french or L bar links, installed properly on three ring risers, put it in a sleeve, pod or bag with the appropriate keeper line, and attach a pretty big throwout pilot chute. PC's have very heavy center lines which pull down the apex and take quite a bit of load I put round reserves in main bags on three ring risers with a TO pilot chute routinely. A 26' LoPo goes in a J3 or V5 easily. I you just want to jump any round jump an old round reserve. About the only rig it will fit in is a tandem rig. It might squeeze into a J7 or a V8 or V9, maybe. I have a RW PC in a pod in a conventional rig and a brand new one pin chest reserve to use. That way your not tempted to cut the PC away to land a square reserve. If your going to do it go whole old school with a ripcord, spring loaded pilot chute and a front mounted round reserve. I'm old for my age. Terry Urban D-8631 FAA DPRE

Okay, what is a reasonabke compromise? I've been rehearsing this argument for weeks. Unless you get to confiscation, what will work? We have a 100 year supply of guns, ammo and magazines. Most of the guns used have been legally ourchased. What would you change in legal purchase process? 10 rd magazines just mean a shooter has to reload twice instead of once, or buy any preexisting magazine. The 94 ban just made ar 15s popular. I can only think of three manufacturers pre ban. Post ban, dozens and dozens and dozens. And a mini 14, I think used in one of this weekends shootings, described as a Ruger hunting type rifle with a 25 round magazine (maybe 10/22) not close to being banned and just as deadly. Give me one new law that will help short of confiscation and I'll support it. I might even support confiscation if I thought that would work. But you would have armed insurrection and there is little doubt that would require a constitutional amendment. Unless you can snap your fingers and disappear 95% of the guns in America and when mothers give weapons to teenagers what do you do? Truely what would you do? I'm old for my age.

The body position was essential flat and stable, slightly head high when towing. Jumper did not look back or roll shoulders (as observed in the videos several months ago). Without reviewing the data in the report in detail the PC that was 'dancing' in the burble produced higher sustained force but more noise in the data. Those that were stable and moving very little seemed to be lower in force but smoother data. I'm old for my age. Terry Urban D-8631 FAA DPRE

I need to review things again myself but essentially yes. The jumper accelerated to teriminal and then fired the AAD cutter with a manual button. The force reported is the peak reading the load cell in the bridle recorded. This is a dynamic system with momentum of the still bag (relative to the rig) the PC slowing down relative to the rig, and the PC having to over come the momentum of the bag when it reaches the end of the bridle. Also this is one reseve/ rig size combination with one rigger. YMMV. This was done to at least have one data point other than goround extraction measurements and to compare to the towed force measurements of the PC. The answer is they all worked. I'm old for my age.

The thanks go to Dave Singer of Perigrine and PIA. As a member of the technical committee I was around for some of the planning and saw the video and data in the spring. Lots of folks think that PIA had lots of resources and ability to take on tasks. In reality we meet twice a year, have one part time employee for administrative functions and limited resources. All of the activities PIA does is done by industry volunteers. In this case PIA funded modification of the rigs for PC towing and the test jumps with video and data recording. Dave put in lots and lots of hours in analyzing and compiling the data. This was partly in response to in adequate information learned when he did wind tunnel testing for his then employer. The committee realized that the only useful data was from a PC in freefall behind a jumper with all of the real life conditions that imposed. This seems like an easy task but with people administering it in their free time and the requirement for all of the testing to be done by one jumper it takes time, effort and money. I'm old for my age. Terry Urban D-8631 FAA DPRE

Only one manufacturer (that I know of) had the pull force data for their PC in real free fall behind a jumper. They were the ones who had put together the wireless load cell and data system. And I'm not sure they had used it in this way before. I know some others had wind tunnel data. What's new is all of the numbers. And this is the first time we have bag extraction forces. Especially with an AAD deployment. And if rigs are tested thousands of times its by customers trying to save their life. These tests took two years and several 10s of thousands of dollars. Remeber PIA is a volunteer organization made up of competitors. Thats why the data is blinded and participants had to agree not to use the data in advertising. There has been doubt by some that even in optimum circumstances rigs would perform perform well. This is a beginning. This is data that most manufacturers didn't have for their own rig. This is public data on container/PC performance that didn't exist before. This data took hundreds of volunteer hours and lots of PIA dollars. What's sad is the manufacturers that chose not to participate. Okay, say thank you now. I'm old for my age. Terry Urban D-8631 FAA DPRE
