IMO this is getting into splitting hairs. I only considered those made specifically for sport use. Back in the '60's, Gary Patmor was doing a lot of work modifying some military openers for sport useage. They were available but really never did catch on. For an AAD, Steve Snyder is the man. Jerry Baumchen Didn't the Russians have a simple and pretty reliable AAD which was basically a wind-up timer.. wind it up like a music box, insert the safety pin attached to a static line connected to the plane... Jumper away pulls the pin, the winder unwinds for, say, 10 seconds and it activates on the main. .... ? KAP-3, developed in the 1930s, I believe.

Also, pull out eliminates 99% of PC-in-tow cases.

For sure SWS Fire has a better launching reserve PC than Wings!: Watch here: https://www.youtube.com/watch?v=KZrbYWt_QqE

Works OK for me now.

thanks for the reply. I'll try these. I've heard about the surgical latex gloves underneath skydiving gloves but this is the first I heard about using them on top of the skydiving gloves. Was there any reason why you specified on top? You will not sweat like in one minute. Also, they will cerate a larger bubble of warm air. But no sweating is the main reason.

2mm neoprene gloves (for under water winter diving) OR normal skydiving summer glowes with the doctor's rubber gloves ON TOP of skydiving gloves.

Not really... Last year in Poland: Student jumper. 29 years old. Stabilized solo jump using a drogue (like a tandem, or some smoke jumper, or military jumper would use). Student pulled the cutaway handle instead of drogue release. Did not pull reserve (handle still in the pocket). MPAAD AAD (made by Mars company, maker of M2 AAD) activated, but the knife did not cut the loop (the knive was found touching the loop). Student hit a sports field at terminal velocity. After impact, the AAD was displaying the code E020, which means "cutter activation or error".

Who's the go-to person for Speed Skydiving advice?

From Mirage Systems: "You've got questions, we have answers! Check out the video on how the Trap Systems works; below our Q&A! Q: Is there any way to “deactivate” the Trap at all? For example, can I disconnect my RSL when I do a CRW jump? A: Yes, we designed it to be flexible to the needs of the jumper and the different type of jumps they may be doing. You have a couple of options with the Trap System: 1) You can completely deactivate it on any jump by simply disconnecting the RSL shackle from the riser. 2) You also have the option to ‘set’ or 'not set' the Trap when your reserve is being re-packed. To ‘not set’ it, your rigger would need to leave the Trap Line off and stow the reserve bridle normally (outside of the Trap). Basically just close the Trap Door and forget it. If the Trap Line is left off during repack then your RSL functions as a normal RSL. Standard Mirage RSL lanyards are black and Trap System lanyards are red. If a Trap System has been ‘not set’ during repack we strongly recommend using a standard black RSL lanyard, instead of the red one, to signal that the rig is functioning with a standard RSL. Q: Can the Trap System release the bridle if necessary after it’s ‘Trapped’? A: Yes. The Trap Line cinches but does not tie a knot. If the reserve pilot chute is creating more drag than the malfunctioned main, then the Trap System will allow the bridle to be released so that the reserve pilot chute can deploy the reserve. Q: What happens if the bridle is tucked into the elastic beyond the red line? A: If the bridle is incorrectly rigged and extends beyond the sewn circle of the Trap Loop it becomes possible for the Trap Line to cinch underneath the bridle. This would allow the bridle to escape and not be ‘trapped’. If the Trap Line is not able to trap the bridle, then you will have a normal deployment in which the reserve pilot chute deploys the reserve (good news), but you will also end up with damage to the Trap elastic which will need to be repaired (bad news). Q: Why is the bottom of the elastic left open instead of sewn closed to form a pocket? A: The bottom of the trap elastic is left open to not hinder the elasticity for holding or releasing the bridle. When the bottom of the elastic was secured during testing, the tendency in packing was to overstuff the bridle into the elastic to ensure it wasn’t being ‘pushed out’ and resulted in a rounded lump inside the elastic. The open bottom is easier to pack, easier to inspect, and allows the bridle to be inserted the full depth of the elastic. Q: Are you accepting orders for the Trap System? A: Yes, it’s an option on our order form. If you have an order in process and wish to add the Trap System, please contact our front office as quickly as possible."

"Advanced Search" link needs changing
skydiverek replied to skydiverek's topic in Error and Bug Reports
"Advanced Search" link in the main Classifieds page needs to change to the "_new" version, because it does not work anymore: http://www.dropzone.com/classifieds/ -
Correct, they used to be like $200 more expensive, now the price is the same as the 'regular' Cypres. No reason not to get one, been out in a field for almost a year, too.

Mine was on the Pilot's warning label (DOM 2008). Maybe it's an old and very used canopy, and the ink just "disapeared" from age?

That's the canopy for you then https://www.youtube.com/watch?v=IK3uWGdh6eA I send seven, not seventy !

No Collins Lanyard either.

The slower opening, the better for me

'Lasso' would be a better name

Do Pilots made after 2009 open somehow worse/faster that Pilots made before 2009? The difference is that before 2009 Pilots had F-111 ribs, and after 2009 they have ZP/ZPX ribs. I browsed thru some posts about Pilot canopies here on Dropozne.com. There are a few posts by Bushman (from Aerodyne), back from 2007 when he was their empployee, saying that they were trying going from F-111 ribs to ZP/ZPX ribs, and the openings got worse on those 'experimental R&D' canopies, back then. I do know that now the ribs are always ZP/ZPX, no F-111 anymore, hence my original question: do Pilots made after 2009 open worse/faster that Pilots made before 2009? Or, did they manage to fix this 'issue' with ZP/ZPX ribs? I am most interested in Pilot 168, normal ZP fabric.

From 3-ring inventor Bill Booth: "Reversed risers are 3 ring risers where the riser rings face the jumpers body, instead of facing away as they do on normal risers. In a misguided attempt to make type 17 (mini) 3 ring risers stronger, the French eliminated the grommet that passes through the riser, thinking this was a weak point. They then put the "0" grommet for the closing loop to go through on a floppy 1" tab. Then, so that the 3-ring housings wouldn't have to come around to the front, flipped the riser over so that the riser rings faced the jumper's shoulders There are three problems with this approach. 1. Risers don't break at the grommet. They break where they go around the harness ring. 2. The closing loop on reversed risers does not make the 180 degree direction change it does on properly built risers, so the release force is doubled, and the "suck through" or "jamming" force is cut in half. 3. For a 3 rings to release, they must flip through each other. Since a bag lock might not stand you up enough to pull the risers away from your body, reversed risers might not release in that situation, because your body blocks the flip through motion. ------------------------------------------- I don't know about you, but I want my 3-rings to work EVERY time, in ANY malfunction situation. "Most of the time" just doesn't cut it. Reversed risers, soft housings, and all other "improvements" to the 3-ring lower reliability. Emergency systems are simply no place to cut corners. I cry every time I see a poorly made 3-ring, but there is nothing I can do about it, but tell you again, "There is one best way to make a 3-ring release system, and it doesn't cost a dime more to do it right. The plans are available from the Relative Workshop." How much is your life worth? ------------------------------------------- On reversed (Integrity) risers...The scariest stories I've heard about them happen in two canopy out situations. Often, the main risers are held back across the shoulders, preventing the unfortunate jumper from cutting the main away in a "personal downplane" situation. Reversed risers offer no advantages, have lower mechanical advantage, have no published construction or inspection specifications (so you can't tell if they are going to work in a high "G" situation), and can kill you in the above situation (and others). They should be replaced, and you should get very mad at anyone who sold them to you. The same is true for most "soft housing" 3-ring release systems.

Looks tapered to me: http://www.performancedesigns.com/docs/linetrims/SI_135-170LT.pdf PD-Reserve is not tapered, for comparison: http://www.performancedesigns.com/docs/linetrims/PR_160-281LT.pdf
