We have a PAC at JSC and on big ways we regularly have 3 outside. The most difficult part of exiting on a pac is the size of the door. So the best idea is to go and practise. The trick in climbing out, for me, is to use the outside step. Ex for the front which is much higher, I place my leg on the step, the one you almost cannot see and then push myself up till I can reach the top bar, or hop and catch it. The rear exit is easier but the same technique. Once you are outside keep closed or you'll blow off. On exit keep small until you are low enough or you'll hit the tail as I am sure a number of people can tell you that on this forum. Also stand on one knee if you can, it will give you extra leverage.

What am I trying to demonstrate? A 105 loaded at 1.0, like what does it react? a 135 loaded at 1.5, 1.7, etc. The point is I am trying to tell the person who has 200 jumps, who does not read Brian Germain's notes or articles that if he/she is intending to jump his 135 loaded at 1.0, that it would be like jumping a 150 loaded at 1.4, cause it makes more sense as we judge it on poeple who weigh 75 - 85 kg. Now we can get a better idea of a person who weighs 98 kg who jumps a 250 cause on a 230 his wingloading is 1.01 and he can't jump something smaller, and vice versa for the small pilot. My calculations are off. "it's like a theorem and an axiom - first one needs to be proven, the other one doesn't. Why prove or test an axiom, when it's self evident? Basic physics, shorter lines, smaller wing... less distance for any given point on the canopy or the pilot to travel in any given maneuver. " Yes I do agree that shorter lines give me ..., tell the pilot who dearly wishes to jump a 79 at a W/L of 2.0 Now because he has 1000 jumps and according to some chart, I think Brian Germain's, when you have 1000 jumps you can jump a canopy at a W/L of 2.0 ... It is these guys who I would like to show what they are doing. "What would be the advantage of the conclusion?" Just different data on different canopies, enablling you to cover a wider range "There are too many variables for a real conclusion to be made. What exactly is 1/4 brake? - How do you ensure that the control input is exactly the same every time on every canopy? How do you make sure that no weight shift input is used every time on every turn on every canopy? How do you ensure that the air mass they are flying through is exactly the same? " This is where the 50 holes come in. 1/4 brakes is when you pull the brakes 1/4 of the way down, now 1/4 brake is just one toggle, other stuff is just a nother variable and when the test is done try and minimise these variables. At the end of the day I want people who are on the high weight and lower weight spectrum to know what they are jumping with. I do not have the authority to stop the guy with 1000 jumps to jump a 79, because all the rules and charts say that he is allowed. I want to show that jumping a 79, loaded at 1.9/ 2.0 is the same as jumping a 96 at a wingloading 2.5. Now I think a lot of people will step back and make a better decision when downsizing from a 110 to a 79

I've read a lot on the forums that people say that a 170 loaded at 1.0 behaves differently that a 105 at a wingloading of 1.0. My big question is not on whether or not this is true but rather is how do you test this? Ok here is the idea, take a few pilots all of diiferent body weights. and set up several test, say all on a 1.0 wing loading but on say 5 different canopies, ranging from a 230 to a 105. The test is simple, do a turn, with a camera and a g-meter, the thing that measure the amount of g-force that is being generated. Do several turns, ex a 90 with a 1/4 brake, measure it, 1/2 brake 90 degree turn. The measurement is how long does it take to do the turn, what g's do you generate and anything else that you will need. You do this test on different wingloadings on different canopies, naturally all on a square/ elliptical/ cross-braced. Now I know there are propably 50 holes in this test but is this test any good? Also has a test like this ever been done and what were the results. Something like this will hopefully show guys about the dangers of different canopies, particularly the smaller guys who fly 79 velo's at a wingloading of 1.9 Ian, if this post is in the wrong place please move it

Tell your son I say congrats

I am proud to say I am NOT a JVX pilot, but the JVX is a great canopy. Bottom line, the debate between which one of these two canopies is the better canopy comes down to style. I like certain things, like soft front risers as I like to dig and work them. The JVX has rock hard risers. Now some people might like that, I don't. The JVX also dives less than the velocity, I like a canopy that dives long. Remember also that the comp velo was designed with the help of the PD factory team and they like ... whatever thast canopy offers, hence the canopy that they fly is that according to their style. Now without trying to sound offensive and I most likely have some facts wrong, would you not say the Jim Slaton like hard front risers hence the JVX is his style canopy. Both Jay and Jim both fly their canpies extremely well. They just have different styles. Lastly look at the top 3 at the world meet, Velo, JVX, Velo, JVX.

Thanks for the pictures t. My side, I've only had about a gazillion times wanted to ask his advice but more recently I have learned what is the difference between a good teacher and a bad teacher. The bad teacher either knows too much, usually do, or think they do, they overflow the amount of work to the student, aka give them too much info. A good teacher knows that he does not know everything, sees the world from his student's perspective and most importantly is still and will always be a student. t was a student up till the day he died. I know cause he asked for advice just the previous evening. From this I can hopefully be a fraction of how good he was

Here is something interesting I picked up. Newton lived in what the 1500-1600? Lets go for arguments sake 1600. Now NASA did their first space walk in the 1950/1960, lets say 1960 for simplicity. It took the smartest people in the world, arguebly of course, 360 years to listen to him when he made that first, and third law, aka you atay still when there is no force and b) very action has .... First guy nearly died when they messed that up.

Having met Ian and the PD guys only once at the world meet I have to say I believe what Ian has said. Secondly when I chatted to JC and Shannon they told me a little bit of what they are planning and from what they told me they succeeded 150%. Congrats to the 4 on making it.

If you swing by in South Africa I'll take you, I love the Tango, also know the Waltz, Foxtrot, Quick Walts, Sokkie, Rumba, Cha-cha, Mambo, jazz swing, Samba, i think that's all. At my studio we do everything , well almost I just know the ten or so that they teach there.

Congrats to all 4 AND our moderator Ian and Jens, enjoy the job everybody here wants

Tonto started something like a wingsuit instructor rating here in South Africa. The rules are very similar to those set out by bird-man. As far as I know, and can someone from our committee or Taya please correct me if I am wrong, it will be a full rating and it will be considered close to if not slightly higher than a jumpmaster.

Final stage starts tomorrow, best of luck to all 15 including those I met at the world meet

clc; g = 9.81; thetao = 10; x = 1; vo = 1; yo = 0; y = tan(thetao)*x - g/(2*vo^2*(cos(thetao))^2)*x^2 + yo Here is the code of the problem you presented I think, you will have to figure out the array, it is basically just x(witha anumbner) and y(withanumber), a for loop and make sure your numbers match

I have around 200+ wingsuit jumps, of those I have doen at least 100+ on a GTI, I can fly with anybody, even a S6 with that suit. Now my SM1 I have 20 jumps, maybe, and I am still shaking after jumping it. my opinion don't buy the suit, better deals will come, and don't dicourage the intro suits, I saw a guy outfly a vampire on an OLD classic.

If you are the foreigner and you are polite in saying hallo or goodbye then it is seen as being polite and friendly. When you say "Howzit my China" and you don't know the person then no. Cheers I use mainly when I say goodbye and I am South African. I don't know of any other way of saying cheers as a greeting except when you clink beer and say "cheers". And yeah, Howzit mainly means hi, but as a foreigner I am not so sure you should use it.

Unofficial results, and don't quote me on this yet 1. Jay Mo 2. Nick batsch Point difference of 20 points SA's two best pilots got 3rd in distance ""GO Chris!!!!!" and 12th place overall to non-other....Rob Kruger. I got 38th which I am happy with considering what has happened to me in the last 2 years. (If you know me you'll know why, if not, don't ask) I just want to thank the 12 million poeple who have helped me get here, OK so maybe it was half the dz, you're still worth 12 million. ps. I may have gotten 38th and Rob 12th but I beated him in SPEED....... YEAH

Some very interresting stuff!!! Wonderboom is around 4500ft above sea level, the average daily temperature is around 30C, wind is between 5 and 10 knots, either crosswind or downwind, slightly into-wind for the speed course. Distance, well it is sure to say we will have a new distance record and we have 5+ contenders for that role, last I heard Nick Batsch went 185m, local Chris Teaque went 180, Marat, Jay Moledski, Jessica Eddington and a few others got or is very close to the 170m+ mark. We have a second sandpit at the end of the distance course set at around 165m, So if you see sand he went faaaaaaaar In the lower field average distances are between 100m to 150m, so if you get 70m.... We are very disappointed in 110m Speed, I have no-idea what the speed record is but Marat unofficially broke it at 2.1 sec today. Chris and some other guys both also set up close to those speeds at 2.47 or thereabout. Accuracy is interresting. we have a whole lot more speed so we have some very fast landings, most are doing ok but we do have some spectacular stuff happening. Weather is looking okish for the meet but we'll see

First off good luck to all the competitors secondly Go team SA

My big problem with 1 canopy is now you are disadvantaging the big boys. Assume one canopy size but with the weight system, a light weight can carry up to 35 lb or 16 kg, that is a wingloading difference on a 120 of 0.29, so have a wingloading of 2.2 for distance and 2.5 for speed????? I say have all the competitors arrive with a fixed weight and one canopy. So if Joe want to jump a 79 velocity with 10 kg of lead then he has to jump that for all the rounds, speed, distance and accuracy. This will level the playing field, I hope, especially as not all people can afford 2 canopies let alone 3. Obviously still add some weight restrictions so that some really big guy suddenly starts to jump with 22 kg of lead but let someone jump one type of system for the whole competition. Isn't that what most people are doing???

Prey, I'll never forget that it took me 5 days to read the first 100 pages and a day the other 200

Wow, been a year since t's death yet it still feals like yesterday. Thought I would like to share some of the good and bad stuff following t's demise. First the bad. Losing t was a bad thing, no two ways around that fact, it schocked most poeple in ways they did not expect. t was well loved all over and he touched a lot of people in many ways. Losing t we lost a lot of confidence in SA regrading wingsuiting, canopy piloting and a great person with whom i learned a lot from. But from all this we were taught how to pick this back up So finally the good. Having somebody die is bad but I would like to tell of the few things that I was given by t following his death. Firstoff I realised how I can help people who are simply put, breaking apart. I obtained t's last student as a great new friend, t's girlfriend Taya has become a truly great friend. But the greatestthing I got which I will carry with me is how he taught people in all walks of life, from skydiving to the lowest class, shack living people to the overly rich, important people. He taught me how to teach people. I am proud to say that that I was taught by one of the greates teachers the world ever had the preveledge to have. Finally to Taya, this day will propably and most knowingly be very hard on you. I do not have the picture so can someone please post it but I want you to remember the outlanding on Sat with the 100+ kids all grabbing and smiling, not a hint of aggression all loving, screaming TONTO!!!!! t, thanks.

Definately, velcro is at its strongest when it is on top of each othe and is pulled sideways And was it a pillow style or loop soft handle? Pillow, my other three were with a metal loop and they were easier to get out

It was a Mirage G4, with a soft handle, on with velcro. The rig has less than 50 jumps on it. A comment, another factor which can play a role is the velcro holding the handle. If you do not peel the handle then I found that it becomes a lot more difficult to pull in either direction.

Long story short, I had my fourth mal today, a spinning mal, cutt away clean, span out of it and got stable. This is where the interresting stuff comes along. I was in the stable belly to earth position, a few seconds after I had cut away I went for my reserve. When I pulled, I pulled down to earth like my training has taught me and I could not pull the handle. I realised my mistake and pulled correctly down to my knees. A few things came of this, 1) I need to think of my reserve when pulling it always in one dierection, ie the way the cable runs down to my knees and 2) this has happened in SA to an uncurrent inexperienced skydiver at JSC and she passed away. I think why I pulled in the wrong direction is two-fold. Firstly I did not want to go head-down and two my visual perception on all of my previous malfunctions, my body was not falling belly-to-earth but rather feet first like I trained in the harness. As confusing as it was for me I have no-idea of how it can be for someone who is uncurrent and inexperienced Figured I need to get this out there and hopefully save a life

I will/ will not/ will/ will not/ thinking/ aaaaaah allright, I'll be there :-)
