mujie96 0 #1 September 17, 2002 Can someone tell me in small, simple words the difference between a collapsible and a standard PC? I ran a search, didn't find much. Thanks. Jess Just keep swimming...just keep swimming.... Quote Share this post Link to post Share on other sites
PhillyKev 0 #2 September 17, 2002 There are two differences. How you pack: Standard...nothing special, fold as normal and stuff in the BOC Collapsible...You must make sure to activate (cock) the PC each time you pack it or you could end up with a pc in tow After deployment: Standard...deploys your main and then bounces around behind your canopy adding additional drag. Cause some performance loss which becomes more noticeable with higher performance canopies. Collapsible..."collapses" (kind of turns inside out, no longer catching air) after deployment to reduce drag. Two types of collapsible PC's, bungee and kill line. I've never seen a bungee so can't speak to that, but the general and most popular usage is a kill line PC. My understanding is that the bungee is more susceptible to problems.

riggerrob 558 #3 September 17, 2002 There are three disadvantages with bungee collapsible pilotchutes: 1. They do not work for the first 5 seconds of a hop and pop. 2. They may re-inflate during an aggressive hook turn. Icarus discourages their use when wing-loadings exceed 1.36 ( if I remember correctly). 3. Bungees need maintenance. First they have to be adjusted by someone who knows what they are doing, secondly, the bungee wears out after a few hundred jumps. Thirdly, if you were silly enough to install a bungee on an F-111 pilotchute, the fabric will eventually wear out and you wil be left with a pilotchute-in-tow. Wait-a-minute! All skydiving gear needs maintenance every once in a while. On the plus side, bungee pilotchutes are almost idiot-proof, since you don't have to cock them. Certainly a wise choice for a junior jumper who is still learning how to pack. Quote Share this post Link to post Share on other sites
mujie96 0 #4 September 17, 2002 So, can I assume that for my very first rig a standard PC will suffice? I'm a very low time jumper and at this point I really don't do anything high performance. Jess Just keep swimming...just keep swimming.... Quote Share this post Link to post Share on other sites
rgoper 0 #5 September 17, 2002 Jess: wouldn't you want a collapsable pc? that way you could see if your pc is "cocked" or not by visually inspecting the "green" or "blue" in the "window" it gives me the warm fuzzies anyway.--Richard-- "We Will Not Be Shaken By Thugs, And Terroist" Quote Share this post Link to post Share on other sites
PhreeZone 15 #6 September 17, 2002 A normal PC will work just find and it elminiates one malfunction. I know lots of jumpers that use them with no problem.Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites
AggieDave 6 #7 September 17, 2002 Normal PCs work great, however, eventually you might want one, so why not pay a little more now for one. Just remember to cock it and to check it/have it checked with your pin checks. --"When I die, may I be surrounded by scattered chrome and burning gasoline."

Jessica 0 #8 September 17, 2002 QuoteSo, can I assume that for my very first rig a standard PC will suffice? Yep. I like mine. Just one less thing to forget or fuck up for a low-timer. Plus it looks really scary (loose threads, orange pvc pipe handle) and freaks out the jumpers with the collapsibles. (And yes, it's in fine, functional shape, riggers the world over have had it hysterically thrust in their faces by me.)

drenaline 0 #9 September 17, 2002 If its you are getting the pc new, go for the kill line because eventually you will like one and it works better than the standard pc. I've been using kill line since jump 18 (now am in 56), just make sure to get your pin check and look at the window.

AndyMan 7 #10 September 18, 2002 Collapsable pilot chutes: 1) are required by high performance canopies. not an issue for you. 2) reduce drag, allowing for faster flight. This means in addition to slightly faster landings, you'll also have slightly better penetration into the wind, and will have a slightly easier time getting back from long spots. 3) pose less of a problem should the pilot chute come over the front edge of the canopy. Some people say that you should get an uncollapsable one, because you might forget to cock the pilot chute during packing. This makes no sense to me. Either you know how to pack, or you don't. "forgetting" to cock the pilot chute makes as much sense to me as forgetting to set the brakes, it's just not an issue. Generaly when people ask me about gear, with the exception of the main canopy I always recomend gear that they'll be able to use for a very long time. While a collapsable pilot chute won't make a big difference now, it will make more of a difference on your second canopy. Buy gear that you plan to keep. _Am__ You put the fun in "funnel" - craichead. Quote Share this post Link to post Share on other sites

mujie96 0 #16 September 18, 2002 A Wings W-10, I talked to Roy at Rigs and Things and he said I could get my 150 in there now and go down to at least a 120 later. I would have tried a W-8 but I'm a chicken so I wanted the "big" reserve. Also, when I start my illicit drug empire I figure I'll invest in a Mirage should I want to go smaller.

drenaline 0 #18 September 18, 2002 Lots of way to prevent that. Concentrate while packing and cock the kill line, cock the kill line again when puting the d-bag inside the container, checking the window after inserting the pin, do a pin check before puting it on and ask another skydiver to give you a pin check before boarding the plane. Just one advice, make sure you remember the color of the line when its cock, and tell the skydiver giving you the pin check, sometimes we don't know what is the color that it is supposed to show. If you pay a packer, you can save some of his work and help prevent that by cocking the kill line yourself. HISPA 21 www.panamafreefall.com Quote Share this post Link to post Share on other sites
maretus 0 #19 September 18, 2002 I don't think that cocking the pilot chute is not so big deal either. You should learn a standard procedure that you do every time and it will be no problem. For example, as I come from jump and lay my canopy down i always cock the pilot chute immediately and after that go take bite, have something to drink, look the video etc. And as phreezone pointed out it is good policy to cock the pilot chute if you are not packing it yourself.http://www.ufufreefly.com Quote Share this post Link to post Share on other sites
dida 0 #20 September 18, 2002 sure, a standard pc will do the job for you. my first rig actually had one of those EVIL bungee collapsible pc's . since i never had to worry about cocking it when packing, now that i do have a kill line pc, it happens that i'm half done packing and realize i didn't cock it. what a pain in the ass it is to go back and cock the pc and watch your packing job go to shit for the same reason that many drop zones changed student gear from ripcord to BOC (create habits that you will continue to use), might i recommend the kill line? spiral out...keep going...

PhillyKev 0 #21 September 18, 2002 Here's a tip if you're laying on your canopy and forgot to cock your PC. Find the window in the bridle that shows whether it's cocked, you can pull the kill line out through that window so there's a length of the kill line hanging out of it, finish bagging your canopy and then you can cock it the normal way and it will draw the line back into the bridle.

Hooknswoop 19 #23 September 18, 2002 Be very careful cocking a PC after the canopy is in the D-bag. If the kill line wraps around fabric as you cock the PC................ Always cock the PC after cocooning the canopy and before putting the canopy in the bag. Aloso, if you cock the PC, then lift the canopy to PRO pack it, the D-bag can slide down the kill line, colapsing, or partially colapsing, the PC.
