Megatron 0 #1 February 9, 2009 Why don't more people use a round reserve. I may be talking out of my ass here but from what I know they're opening characteristics are more stable, theyre less prone to malfunction, and are aren't as sensitive to body position on opening. Plus, they are far more compatible in a two-out scenario with a ram-air. Like I said, some of what I wrote may be untrue..just going on what I've heard so please give your input on the subject.

Megatron 0 #3 February 9, 2009 I'm assuming that's referring to the fact that most rounds arent steerable. If what I wrote above is true then perhaps the increase in reliability is worth the loss of control. I would much rather deal with landing off or even in some trees than have a reserve mal and smash into the pea pit face first..something to consider. What about steerable rounds?

Andrewwhyte 1 #4 February 9, 2009 The malfunction rate for most rounds was much higher than it is for a modern rectangular canopy. The real reason they are out of fashion is they are generally larger, bulkier, heavier and land worse. Quote Share this post Link to post Share on other sites
billvon 2,400 #5 February 9, 2009 1) Riggers are unfamiliar with them, and many containers are not certified for use with them. 2) They have either little or no glide, which means you'll be landing out. 3) They land you very hard. A PLF is required, and few people know how to do them nowadays. 4) They fly very differently than your main, and that's another thing to deal with during a cutaway. 5) Older rounds had a pretty high malfunction rate. (Newer ones with anti-inversion netting are much better, but not readily available to skydivers.) OTOH, if the main reason you got a cypres was "in case I get knocked out" a big round will land you more safely if you're unconscious - and will not cause as much trouble if you pull low and have a two-out.

phoenixlpr 0 #6 February 9, 2009 Why don't you try to get a jump with a round main? Than you see why most of the people don't want to use them anymore. FYI even some pilot bail-out rig can have square reserve... Quote Share this post Link to post Share on other sites

SEREJumper 1 #9 February 9, 2009 If your DZ is around a lot of population, even a steerable round reserve may not give you a chance to at least pick your landing spot. You are pretty much at the mercy of the winds. Having buildings and power lines beneath you and a round above you is not a good combo.We're not fucking flying airplanes are we, no we're flying a glorified kite with no power and it should be flown like one! - Stratostar Quote Share this post Link to post Share on other sites

wmw999 2,121 #12 February 9, 2009 One thing about spotting for a round reserve when you have a square main is that you're spotting to make it somewhere safe, not necessarily the DZ. Assume that an out landing is in your future if there are noticeable winds, a square main, and a round reserve. That's not necessarily an advantage, but it's pretty accurate. Wendy W.There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence.

DrewEckhardt 0 #16 February 9, 2009 QuoteI'm assuming that's referring to the fact that most rounds arent steerable Modern rounds are steerable, they just don't have enough forward speed to go anywhere to get you away from the forrest, gator infested swamp, or shotgun wileding farmer's field that you opened over. Quote . If what I wrote above is true then perhaps the increase in reliability is worth the loss of control. I would much rather deal with landing off or even in some trees than have a reserve mal and smash into the pea pit face first..something to consider. What about steerable rounds? Your chances of a reserve malfunction that did not result from operating the canopy past its design limits (like a head-down Cypress fire in excess of 130 knots for older designs), criminal negligence packing (a molar strap around the reserve would do it), or errors in your emergency procedure execution (opening the reserve an then cutting away can lead to entanglements) are pretty much zero. Low aspect ratio rectangular seven cells with forty-five minute pack jobs are a completely different animal than high aspect ratio tapered designs with six minute pack jobs.
