Hi guys, I hope I'm posting in the right place. It's a combined gear/skydive/mall function question. I've been told that a streamer it's a mall function in which the canopy it's not opening, the slider is not visible and it's a high speed mall function. I've also learnt that the streamer may cause enough drag to position you standing up vertically and that would increase your fall rate even more than the average speed in box position (200 km/h). This mean that you need to fix it even faster than a bag-lock for instance since the fall speed it's faster. I know that at 200 km/h (box position) I can't stay in a vertical position since it's unstable equilibrium and for sure I don't have the skills to do it. If the speed of the streamer is bigger than or around 200 km/h how come you are positioned vertically and stable? I've also seen movies in which skydivers are trying a hybrid 3 way and the skydiver that was suppose to hang down vertically from the other 2 he just can't do it and he always bounce back to box position. How come is that possible for a streamer to keep you standing up at speed bigger than 200 km/h and in the hybrid 3 way example is not? Also I've just finishing watching the movie Fandango from 1985 with an amazing skydiving training&jump scene. In the movie they are jumping round parachutes and when they make practice on ground for mall functions they are talking about the streamer. Isn't it the streamer specific only for ram-air parachutes that have sliders? Lock, Dock and Two Smoking Barrelrolls!

Hi again, I've just arrived from the dropzone and (drum drum drum) It's back. My ARCH is back. I want to than you all for all the good advices and for being there for me in the moment of need. I've did lots and lots of arch practising with stacks of pillows so I could have a position close to the position in the air. I can't tell for sure what I've did to get it back but I've got it and I've got an amazing jump just few hours ago. I've exit like IAD hanging with my right hand and looking at a tandem instructor and student preparing for exit (out of a Cessna 182) I've let got of the wing bar and bring my feet in front of me while holding my knee with my hands (like a sphere position). Did some fast uncontrollable rotations while in that position for like 3-4 sec and then I've begin to arch and went stable like snow flake. I did some pull practice, some 360 rotations (left and right) and I've tried to track from 6000 to 5000 (not sure how good it was that tracking thingy). During my free-fall I did a heel clicky and hold my heels together for 3 sec and I was still stable. I've pulled a bit lower than 5000 maybe 4800 and I've guessed wrong the wind direction, did the inverse U patten, landing with the wind in the back and went straight in to the trees :). Nothing broken not even my pride (because I got my arch back). Boy it's good to be back on the track. I can't wait for my next jump. I really appreciate all the input and help that I got from you guys and believe me when I say for me it was a real pleasure (yes it was - I've got my arch back or I've got my back arched). Sign, A stable jumper. P.S. I hope I'm not gone lose it again:) (the arch that is). Lock, Dock and Two Smoking Barrelrolls!

Yes I'm planning in adding the instructor in the loop off course. It was never my intention to keep them away from the problem. I just wanted to see if anyone out there had a similar problem and if anyone knows a GOOD way (close to real free fall muscle feeling) to practice the arch while being on the ground. I've read some other threads from DZ.com about bad arch's and peoples are suggesting to use a gym ball (the BIG one) and just laying with the back on it or using the water from pool in the same way we use the air while free falling and practice the arch in a water pool. I got this lazy boy that when fully extended if you just rotate yourself with 180 degree and have your legs where your back use to be it feels like a good arch. For the legs is good because the muscles are not used to maintain that position (they are supported by the chair) so they are relaxed but for the hands is not that great since when I'm arching the upper body muscles are contracted and not relaxed. And unfortunately no wind tunnel in here :(. One of the problem is while I'm practicing the arch I don't know if it's really going to help me because it really feels different up there :(. I really hope that after the next jump I'll be able to tell you all that I got it back and I don't know how could I've lost it (duhhh) but for now I'm still in the fog (metaphoric speaking off course) and when you are in fog you see fog and only fog all around you :( Thanks guys for all the answers and advices. They are all appreciated. Lock, Dock and Two Smoking Barrelrolls!

Thanks for the advice and I hope that I'll be able to do it right next time. It's a bit bad because the season is almost over and now is not a good time to lose the mojo :(. Lock, Dock and Two Smoking Barrelrolls!

First I would like to thank you all for all the replies. I was thinking that it might be my legs or my shoulders because it all started after I've looked at the altimeter. What I'm planning to do is just have another solo with my old gear (that heavy 300 sq ft) and my old routine (visualization and not being so confident - that's an easy one now) and if I can't get my arch back I shall go back to level 5. I really feel that I've let my instructors down. I am looking for ways to practice my arch on ground but whenever I'm doing that I notice that all my leg muscles are flexed. Do you guys have other alternate methods for arch practice that are close to the real free fall? My last jump was a big disappointment for me. I've lost something (magic dust maybe) and I can't fly anymore. This really sucks. Again thank you all for all the kind advices. Lock, Dock and Two Smoking Barrelrolls!

Hi, Let me start with a small introduction. I am a humble student who finds himself in a very unpleasant and shameful situation: I've lost my arch. During my last AFF (level 6) I was stable, I was able to do all the rotations required and when for a couple of few sec during my pull practice I've got a small spin and a bumpy ride I've just let go of any air resistance resistance from my side against the air flow and I've relaxed and got stable pretty fast and lost the lazy spin (the Jump Master didn't have to help me in any way). I haven't see any line-twist since my AFF1. After my level 6 I really felt ready for my 1st solo. On my first solo everything got screwed up. I've exit unstable I've begin to arch and got really fast into belly to earth position. We jump from 11.500 feet and I was pretty stable in the 1st 10 sec. I've checked the altitude it was around 10.000 feet and I've noticed that I have a lazy spin to the left. I've started a rotation to right in order to stop the spin but .... instead of balancing the spin and get neutral I've begin to experience a bumpy ride and the left spin got bigger. I've did the exact same thing as on level 6 (from what I've felt) let go of any resistance against the air and try to relax but the spin to the left got bigger and bigger. I said to myself that I have to do something to reset my position and I've did a back flip. It worked like a reset but I still had a small rotation that once again begin to increase in angular speed. I did another back flip and I've ended on my back. This was around 7000 feet. While on the back I wondering if I can reach the handle and I start a pull practice while being on the back. Strange thing I couldn't find the handle (maybe the wind flow move the container a bit upper). I've just get back on the belly check the altitude and open the parachute around 5200 feet (no line twist don't ask me how). All the time I had the bumpy ride feeling and I was not able to do anything to get stable. For me it felt like I was doing the same things: I had the same feeling of my hands and feet when trying to relax as on level 6 but it was not working this time. More info regarding my solo jump: - I had a small back pain when I've practice arching on the ground (but I had it even on level 6). - I've changed the gear from 300 sq ft to 230 sq ft and I felt the container to be so much lighter. - During the ascent I had some problems with blood circulation in my legs. - I've change the jump suit to a solo jump suit that was just right for me (on level 6 I had one a bit bigger one - maybe more drag). - During the ascent of the plane I was confident (never been that before) - maybe a bit cocky (not that much, just yelling and talking with other jumpers like I was not worried about the jump). Also I haven't done any visualization practice during my ascent. I'm waiting for any kind of input (negative or positive) from you guys regarding my lost arch problem. If you feel that you had an experience somehow similar with this I would love to hear your story. I really, really feel bad about this. Should I ask again for 2 jumps with a instructor so I could get some input about what I'm doing wrong? Should I try to practise my arch more on the ground but the thing is when I practise my arch on the ground all my muscles are not relaxed.

You sense the freq of 250 hz because on that freq the amplitude of the combine signals (500hz, 750hz, 1000hz) is maximum (the peak)? How does that work if one of the original signal has a different offset (phase)? Lock, Dock and Two Smoking Barrelrolls!
