    Static Line Only Jumps

    So there's the question of whether to go for option 1 or 2 or maybe a 3rd. 1. Just do static line jumps, remaining a student. Requires the appropriate aircraft and instructor and supervision every jump. Costs more and may not be available at all times at the DZ, depending on how many static line jumps they do. The only gear you can use will generally be dropzone student gear that's set up for static line. 2. Get a full license. Allows you do do hop and pops with regular equipment out of more aircraft and more dropzones. But it requires learning a wider range of skills, as expected for the typical beginning skydiver, including freefall maneuvering skills. 3. Get a restricted license. Here I'll have to defer to those in the USPA instructing system. Blind people and others have gotten licenses with certain restrictions, I think. Is it possible to get one that would work for hop and pop's only?? Just sticking to static line jumps might be pretty awkward unless your current dropzone really wants to work with you and does a lot of static line. You would be able to use normal freefall gear and supervise yourself (taking much less time to arrange each jump), but not have to learn freefall skills you don't plan to use. As Seth says though, once you do a bunch of jumps and get to a particular stage, you like many others might want to go a little further, beyond just static line or even hop and pop jumps. Scaring yourself a little with new things (including those first practice ripcord pulls) is part of skydiving...
  2. I'm also OK with the use of "streamer" for a square that snivels forever but never has the slider come down. Maybe some of you remember the big laminated malfunction photos / giant flashcards that some DZ's had for their FJCs? I don't know who buys them now, but they've been around, who knows, maybe 30 years. Their list of mal photos does include the streamer: 1. Broken Lines 2. Line Twists 3. Bag Lock 4. Slider-up with Spin 5. Slider-up Snivel 6. Pilot Chute-in-tow 7. Closed Endcells 8. Line-Over 9. Slider-up with Twists 10. Square Reserve Out with Main Out 11. Round Reserve Out with Main Out 12. Streamer 13. Horseshoe 14. Pilot Chute Under the Nose (Source: SkyHi Video Productions website.They are still around!) Hmm, but now I'm wondering, how is #5, the "Slider-up snivel" any different?

    information needed

    I recall the PISA Naro being one of the ugliest rigs around at the time. But it seemed to be functional. Can't recall how freefly friendly the flaps and covers were. PISA was absorbed into Aerodyne in 2003, and discontinued their harnesses at that time. (At least according to a press release I have of the era.) The Naro wasn't seen much in North America. No service life limit - why would there be? Oh... you're in Australia where you sometimes get those funny rules. So the value of the rig is likely minimal, although technically probably just fine to jump.

    In defense of Icarus Tandem

    Haha! That's considered evil in places using UPT rules or the US Tandem Commandments -- no turns over 90 below 500', stabilized on final by 100'. They all want long boring unaccelerated final approaches. They don't care if you say, "I never banked more than 20 degrees" or "I never brought my toggle below my shoulder". But yeah I know what you're getting at. A gentle curving approach consistent with traffic does improve canopy rigidity and resistance to turbulence for pretty much any canopy. Still, the idea is supposed to be that one should be able to land one's tandem canopy without resorting to such measures. So saying 'the Icarus is great if you swoop it a little' isn't going to win you fans in some circles.
  5. FWIW, the other 2 parts: https://uspa.org/safetyday/the-secrets-of-db-cooper-part-two-evidence-of-absence https://uspa.org/p/Article/the-secrets-of-db-cooper-part-three-criminal-profile (Part 2 is crammed over to the side of the page, awkward to read. I didn't see a better version but it may be out there.) From 2003, apparently updated in 2010.

    1st Cut-Away - Reserve entangled with Main

    I could have been more precise and correct about how the main can end up "around" the reserve: 1) I said how I thought the PC & freebag went between risers or lines (within a riser group). Additionally, they could have gone above the slider. Same issue though: It would need some line caught on the rig or jumper to create a gap to go through. 2) Or an entanglement can happen with nothing of the reserve going "through" the main, if the reserve extended but "barberpoled", wrapping itself around the malfunctioned main, especially if the jumper and main were spinning generally along the axis from jumper through main. That's a more traditional main-reserve entanglement. But it would take more than 1/10th second of cutaway delay for that. A full second might be enough though, who knows.

    1st Cut-Away - Reserve entangled with Main

    Yikes. There's long been the worry that someone might occasionally get the Cutaway & Reserve just a little out of order, if they are trying to "pull simultaneously", or even do a "quick one-two", which is a better strategy. Maybe the cutaway handle takes a little more force (whether due to forces on the cables or just good velcro), so the reserve pull ends up early. I'm wondering if maybe you had a line or line group caught on you or around the bottom corner of the rig or something, after deploying unstable or head down. Only that seems to explain the situation. So I'm guessing you were entangled in your main after all. (I'm not expecting you to know 100% what's happening behind you during a nasty malfunction whipping you around!) If one is just in line twists, each set of risers tends to have front and rear close together, very little space for the reserve to go through. Plus, it wasn't just the reserve pilot chute getting through some part of the main lines, in which case the freebag would have solved the issue and you and the reserve would be free. For the main lines to be around the reserve lines, the whole freebag had to go between risers or lines -- such as when some lines are entangled on you somewhere. That can result in a spinny mess with a line over or just something looking like one. You got a little over amped on the main pull (when you had time to wait a couple more seconds easily), and had the same with the reserve pull. But great job on keeping on fighting and actually using the hook knife. And managing to not cut any reserve lines in the process! It is very very rare for anyone to ever use a hook knife. Not unknown though, so it's still best to have one.

    What happened here? Turbulence? Stall?

    Now I could be entirely wrong, and I only watched the collapse, not the rest of the vid. Looks familiar, this little incident that was a good advertisement for a Skyhook. That came up a while back on DZ. I know it as the Dubai swoop comp collapse, Dec 2011. Think it was blamed on turbulence, causing the frontal stall or frontal collapse (negative angle of attack). Possibly in some way combined with it being on an early non-production version of a Petra, a prototype if you will. But I don't know the details. Search for "JPX Petra - stability issues?" thread.

    LARGE GEAR

    Fair enough, there is that TSO C23b, based on 1949 standards, that makes things 'more legal' by having few limits!

    LARGE GEAR

    At the OP: Rigger Lee got at this a bit, but you'll be pushing the certification limits of standard gear. Some rigs are certified to the old traditional 254 lbs (jumper plus gear), others as high as 300 lbs, but I'm not sure if there's anything beyond that. (Unless one uses adapted tandem or military gear.) So it might be hard to be totally legal. Not that people haven't slightly overloaded gear before. People over 230 lbs (without gear) skydived even when nothing was certified past 254 lbs, so with the available gear they were always overloading it a little. Reserve canopies have a similar issue to the rig itself. E.g, the biggest PD reserves, whether regular or Optimum variety, max out at 290-300 lbs for certification. So, similar to what Lee is saying, you at least want to maximize things in your favor by considering gear features that are more forgiving of high weights and speeds.
  11. at OP: I figure you're just talking about being stopped from jumping in "some weather" due to winds. Not that you're hoping to jump through 10,000' of rain and cloud. (I personally think Skybitch's comments seem a bit harsh if they are a riposte to your comment, but are educational when talking about weather issues in general.) Your being stopped from jumping in higher winds is probably more a function of what is allowed at your license level (assuming you are under USPA rules or similar), than the size of the canopy. One can fly big canopies in strong winds... it just gets a lot more challenging. I have jumped student size canopies where I've backed up right to touch down. Takes a little more planning and of course one can't do a regular pattern. In some locations and cases, tons of wind will lead to tons of turbulence, in which case fewer and fewer jumpers, even experienced ones, will want to be in the air at all. In that case it isn't just about wind speed. So yes you may feel more comfortable when maneuvering around with a smaller canopy when winds are higher, and may indeed be safer. If an instructor grounds you due to winds though, it's likely because they are grounding all Students, and not just because you're on a 280. Still I hope you get to downsize a few sizes quickly from that level - especially when you've already flown smaller. (At a different DZ?)

    Monterey Skydive should be called out!

    @RatelSquadron - Every dropzone (unless it just opened) will have had accidents. Maybe not fatal, but there will be injuries. - Dropzones might get just a little unethical or deceptive about accidents because they may be talking about their first jump students, or their students in general, but not licensed skydivers. The DZ wants you to know about the safety of their student programs, not what happens to experienced jumpers who take on more risk on their own. The DZ should be clear what they are talking about. A DZ may be fighting public misperceptions. If a skydiver dies at a dropzone, it often has nothing to do with the school or how students are treated. No more than how a ski school on the bunny slopes may be safe, while experienced skiers take the lifts to get to the backcountry where they do some dangerous things -- unrelated to the novice skier's experience. - Gerado Flores was an idiot, liar,and a laughing stock among just about any skydiver who heard his tale. - Some of the equipment he rented may have been older or worn, but that doesn't mean it was too bad to use. It may also have been less than suitable for some types of jumping (non-belly jumps). Gerado chose to jump it, and jumped it in a manner not consistent with what he told the dropzone he was going to do. - Still, skydivers did debate whether the gear was suitable, whether it was just "older and worn but serviceable", or really was getting "a bit sketchy". Those of us out on the internet can't know for sure as we didn't see the equipment. We can't exonerate the DZ, but can't automatically blame it either. - The gear inspection by the FAA and Allen Silver was an abomination, complete crap. While Allen Silver is highly respected in emergency parachute circles, I believe he was long out of sport skydiving. Maybe he was only given a very short time to inspect the gear. In any case, any experienced skydiver reading the report would see it to be complete crap, being vague or erroneous or missing the point or not putting things in any sort of context. It left so many questions open, and failed to ask various important questions, that I can't draw any real conclusions from it about whether or not the gear was acceptable to jump. (For example, the report completely fails to note when some damage seen on the rig -- broken lines -- might likely be a result of Flores' jump and inadvertent opening, while making the non-skydiver reader think the damage existed before the jump. Two very different things.) - So it was terrible that that FAA report went out to the public and was used in media reports to try to discredit the dropzone. Skydive Monterey should be clear when talking to people, just what they mean when they talk about their safety record.

    Using risers with RSL on other side..

    I've seen it done and am OK with it. The mechanics of the RSL pull shouldn't introduce any forces too much different than normal. Have to watch the RSL routing though. Depending on where the RSL is situated (on the reserve risers or under or inboard of them), someone might route the RSL UNDER the reserve risers instead of over top, to get to the outboard side instead of inboard. (Might still work despite dragging the RSL under the risers before the reserve is released. Even weirder and scarier if a MARD were involved.) Plus it just looks weird and is confusing to anyone who is helping with a gear check. So I tend to recommend it as temporary only, until one gets some new risers shipped in...

    Toggle fire mechanics

    For others: Skip to 2:25. And turn your volume down. Nice job getting out of spinning line twists. And then dealing with the popped toggle. The video is kind of good in that it shows less than instant & perfect reactions too (not a "See I'm great" video), as it takes a while to reach up far enough to get to the toggle. (Sunk in harness a bit from G's? Wingsuit restricting arms?) Actually he happens to get to the stowed toggle just before the popped toggle. Whatever works!
  15. I thought Branch did pack lines to bottom... since it was bridle towards the "bottom of thereserve container", which is bridle towards the head. Anyway, whatever the confusion over a lack of consistent skydiver terminology regarding directional axes, that sounds like a super tight main if one has to pull up at 25 lbs on the bridle to rotate the bag out...
