  1. It appears that the butcher's bill is 0 this weekend. Excellent work folks! Keep it up! -- Toggle Whippin' Yahoo Skydiving is easy. All you have to do is relax while plummetting at 120 mph from 10,000' with nothing but some nylon and webbing to save you.
  2. It so happens that I have a top quality personal X right here with me! Very cheap, only $100 USD. Think of the savings in jump money it will give you! It's top quality, with a high tech security system. To guarantee that you are the only one who can use it, it is invisible to others -- Toggle Whippin' Yahoo Skydiving is easy.

  3. Sitting is hard, but fun. RW is great fun too, even though in some places it is considered uncool. Try to do a 2 way flat with someone, see how many points you guys can do. Or maybe build a big round. It's all much harder and a lot more fun than some freefliers make it sound One of the most incredible skydiving activities for me is flying around with my friends under canopy. Get out, pull at 9 and chase each other down to 4. Great fun. Try some low exits, work on accuracy. Kicking a cone you placed on the ground before taking off as you stand up your landing is a very good feeling, but somewhat hard. Or you could just do some I'm-getting-out-alone-and-screwing-around-for-10000-feet dives See how many barrel rolls you can do before you get dizzy. Flip over on your back, kick back, relax, pretend you're lying on a couch (make sure you talk to someone before doing this, your altimeter becomes less accurate in this body position). At a DZ like Skydive Chicago you should have no problem. -- Toggle Whippin' Yahoo Skydiving is easy.

  5. Hey Glen, it's Eugene. Congrats man! That's awesome! Finally, after a year of trying Is Dave gone already? If not, why don't you go for a 10 way tomorrow? This is great news.

  6. I believe I have made that point in several places in my post. If I did not emphasize that enough, let me say so again here. There are people who swear by Russian equipment. However, it's possible that a lot of it is military surplus. We don't know. Edited to add: I would jump a Russian built rig, main and reserve, as long as none of them are round and the rig has all the modern features (3 rings and modern reserve activation methods especially). I would not jump an American or European built rig that has round canopies (except on special preplanned occasions) or does not have the features listed above. -- Toggle Whippin' Yahoo Skydiving is easy.

  7. Please remember that I am only a beginner in this sport, and may be wrong about what I am saying here. Would the highly experienced, especially riggers (riggerrob), verify my words please? Georgia Jump: These guys say that their gear has been made in the USA, which would make it fine. I can't tell if they're AAD equipped, but they suggest so. The "klassicheskii prizhek" course uses a round. Avoid rounds, rounds are not good. As I understand, in Russia they believe that rounds are better for lower time skydivers because you can't hook turn with them. You also can't very well steer with them, and can't land very softly with them. You may less likely to kill yourself on landing with a round, but you are more likely to sprain/break things because of harder landings, and you are more likely to land on things you don't want to land on, like trees and powerlines. Don't jump with rounds. A more experienced jumper may be more enlightening, as I have never myself jumped a round parachute. The tandem jump looks perfect, they use Strong parachute systems if I'm telling correctly from their photograph. These are excellent equipment that we use here in Canada, as well as in the States. Not my personal preference, but they definitely work. Here's a link to the picture from which I deduced that the rig is a Strong: http://www.georgiajump.ru/Photo/0044.jpg The static line course is how I trained. It's probably very different in Russia, but the system they use at least has square parachutes in it, which is a bonus. It's very difficult to tell just by looking at the webpage. I would call them perhaps, if you have someone who knows the right questions to ask. More importantly, you need someone who knows what the right answers to those questions are. We could help you here if you want, but it's gonna be tough over the internet. AFF: I'm not sure whether this is a USPA certified AFF program, but again they seem to be ok. I have the same thing to say about this as about the static line. Their description of it in "Dalneyshee obuchenie" sounds like an American style AFF program. I would recommend you do this after a tandem jump if you want to be fully certified in this club. skydive.samara.org: More difficult to tell. They seem to do tandem jumps with Vectors. Perhaps they mean Sigmas, since the Sigma is a tandem parachute system made by Relative Workshop, and Vector is a sport parachute container made by the same company. However, it is possible that this Vector is a Russian homemade system, I can't tell. Even so, it's probably fine. These people don't appear to specialize in parachute jumps, but their history as an aviation club is impressive. I don't know what to say about them, not enough information. Edited to add: Their FAQ says that everything except the tandem systems is definitely Russian. The "uchebno trenirovochnii parashut" D-1-5U, if I remember correctly (and I may be wrong here), is a round canopy. I am not familiar with any of this equipment. It does not appear to be American or European. It's probably fine anyway, it just means that we don't know anything about it. On a final note, I don't read the Russian skydiving webpages. I think that there is a Russian page similar to dropzone.com, with forums and fatality reports. I don't read it because I don't live there. If you look through it you might find more informed opinions. Basically, I'm not sure what to say. Both seem fine, Georgia Jump has a bit more information on their page, and they seem to do AFF, so I would recommend them, but that's only because they have a better webpage... Again I plea that experienced jumpers verify everything I said. -- Toggle Whippin' Yahoo Skydiving is easy.

  8. Russians have very solid RW competition teams, and I heard there are people who make excellent gear in Russia. If you go to the right dropzone, I'm sure you would get excellent service. -- Toggle Whippin' Yahoo Skydiving is easy.

  9. I'm a Canadian skydiver trained in Canada. I'm Russian born, so I understand you. However, remember the "business soul" in Russia. I would trust my life to them only if I knew them personally. That does not mean there aren't good DZs with good people, it's just that Russians know the reputation of Russian businessmen better than anyone I think. Check out Gananoque. I've met skydivers from there and they're great people. I heard about a dropzone north (?) of Montreal that has an absolutely excellent first jump and student training program, I'm sorry but I can't remember the name. It's pretty hard to go wrong with student training in Canada. Train here, then come visit me -- Toggle Whippin' Yahoo Skydiving is easy.

    I think they mean writing in the next 10 jumps or so, before you make them. Just the numbers, of course. -- Toggle Whippin' Yahoo Skydiving is easy. All you have to do is relax while plummetting at 120 mph from 10,000' with nothing but some nylon and webbing to save you.
  12. Absolutely correct, but weirdness has happened before. In particular, especially if the alti is a bit old, the needle could stick. Honestly, when I look at my alti bouncing around, I get a little worried that the needle could dislodge and start reading incorrectly. Anyway, I'm no expert, mostly just wanted to point out that perfectly good altis can, and do, read incorrectly sometimes. -- Toggle Whippin' Yahoo Skydiving is easy.

    Hey man. I think that the fortune cookie is just a catalyst, and that you've had those doubts all along. Don't make any earth shattering decisions lightly, they're hard to reverse. And that idea of putting it in your reserve flap is awesome, do it As to me, I'm not superstitious about my gear, but I'm beginning to develop this weird habit. When people give each other the ritual high fives at around 10 grand, I really don't like to give someone a high five with my left hand. It somehow feels that I've jinxed them. I usually just suppress it, but hey. -- Toggle Whippin' Yahoo Skydiving is easy.

  15. Depending on your style of tracking, you may create a burble between your chest and hips. It feels like a cushion of air on your stomach. In this case, your altimeter can be inside this burble and read several thousand feet too high. This sounds like the most reasonable explanation here. For me, I have seen my altimeter go haywire, but it happens differently from your description. My needle starts bouncing around a lot, +/- 1500 feet, so that the altimeter is impossible to read. It happens during sitflying sometimes (I have perfect body position according to Dave Brown, but a very flappy and baggy suit) and during tracking. The best way I know to avoid it when tracking is to switch to a delta with your arms out, check the alti, then go back to hard track. This should not be necessary if you're breaking off an RW/Freefly jump, counting, eyeballing and the internal clock should be enough. It doesn't sound like your altimeter is broken to me, it sounds like it functions as appropriate, which is, it's sensing the pressure around it. You probably just put it into a low pressure area. It's good to understand that these things are possible and do happen on a daily basis. Read your SIM, it details other situations, such as backtracking, when this could happen. Remember, there's nothing magical about your altimeter, it's a mechanical piece of equipment that senses air pressure and displays it on a dial, calibrated to correspond to altitude.

    Metrosexuals?

    If I didn't know better, I would say someone seems to be feeling threatened! Seriously, why do you folks care what these people do? How does it affect any one of us? I bet about as many men wear makeup as skydive, overall. It's pretty funny to hear skydivers talk about queers and societal deviants Just imagine, in a couple hundred years a bunch of people will be sitting in a history class. Maybe about half of them will be openly bi/homosexual, since it will finally be accepted. They would be learning about the 20th and 21st centuries, and as an aside their lecturer will tell them how some weirdos actually threw themselves out of these things they had back then that they called "airplanes". -- Toggle Whippin' Yahoo Skydiving is easy.

  19. The most important part of a landing is your visual radar, no? I mean, first person down and all that aside, it's important not to set up for final heading straight for another canopy. Assess the pattern and fly with everyone else. For me, the rules we have at our dropzone regarding the landing direction are a guideline that I use to place my mental checkpoints for where I want to be when. Once people start landing, I observe what is going on. Once I'm in the pattern, I follow the pattern. If this means landing downwind, that's where I'm going, it beats canopy collisions any day. Also remember that you do not have to land on the dropzone. If the landing area does not seem kosher, land out. Too many people? Too chaotic? Just doesn't feel right? Buddy fresh off student status seems to be converging for the same spot as you are? If you know the LZ and all the outs, what's the problem? Cheers. -- Toggle Whippin' Yahoo Skydiving is easy.

  20. What about structural damage to an Otter that wedges the door closed after a crash? There is a jumper at the DZ I jump at who has witnessed, and helped in the rescue efforts of, an Otter crash with a closed door where the door got stuck because the fuselage was bent. He says it took them a good 2 minutes to get that door open, the interior was full of fuel and one of the engines was on fire. He said he was afraid for his life, and he wasn't even inside the airplane. -- Toggle Whippin' Yahoo Skydiving is easy.

  21. Whatever you say, professor. The idea is that in some very special cases, you could pretend that the Taylor expansion of the solution has the first couple of terms to be what you want to make the DE essentially trivial. It was a homework exercise, to find cases where the error is bounded. I haven't dealt with DEs ever since, so it's possible that this approximation is something the professor came up with as a homework exercise. Anyway, I already found the solution. -- Toggle Whippin' Yahoo Skydiving is easy.

  22. Fine, I'll do it. Nonlinear nonhomogeneous first order DE, yay. It's of the form df/dx ~ 1-f^2, so as you suggest, set v = a tanh (ct). Then dv/dt = a (1 - tanh^2 (ct)) c. Since tanh^2 (ct) = v^2 / a^2, we have dv/dt = a (1 - v^2 / a^2) c = (a - v^2/a) c. Setting a = V and c = g/V we are done. Solution is: v = V tanh (gt/V) Plugging in some numbers, the lazy method gave an error of about a factor of 2. Edit: Which is very interesting considering that protrack graph. Hrm. Must have been that SAS measurement, instead of TAS. -- Toggle Whippin' Yahoo Skydiving is easy.

  23. Yep, I know. I used the "integrate both sides of an equal sign to get something approximate" method of solving DEs Plugging in e^ax would be the right way to go about it, yeah. Integrating both sides of an ODE sometimes gives a polynomial solution that is accurate up to some terms of the Taylor expansion of the actual solution. I was hoping this could give a similar behaviour when v/V < 1. Of course the asymptotic behaviour would be wrong. -- Toggle Whippin' Yahoo Skydiving is easy.
