Well equation for lift is: L = (Ro * (V*V) * Cl * S)/2 L - Lift Ro - density of air (Sorry, no greek leters in here) V - Velocity Cl - Coefficient of lift S- area So for you to be able to land your canopy. it has to produce enough lift so that it matches or exceeds your total weight. So the higher the density the higher the lift force is. But let's say that the density is given. What you can change is V (your speed) or Cl (coefficient of lift). Cl is changed by flaring (if i start explaining that it will be one loong post, so i wont). So theoretically you have to have a lot of speed and big Cl. you can do that by doing a "HP landing", where you have tons of speed. guys at PST are swooping canopies at speeds 100km/h. So theoreticaly you could land it very high (MSL) but would you dare stepping on the ground when you'd still have 80km/h horizontal speed in a swoop, because at 70km/h (for example) the canopy won't support your weight anymore. And the higher you are the sooner (at higher speed) the canopy will stop producing enough lift to support your weight. So it's not really a definite answer for "how high (MSL) can you land". It depends on at what speed (in a swoop) do you dare to step down. More guts (or less brain) you have, at higher MSL you can land "George just lucky i guess!"

Yes he does, don't worry i'll kick his but for this, the next time i see him btw Great video unutch, though you coold pick another music for that formation style jumps. I'm still having a head ache... "George just lucky i guess!"

Hmm i'm not sure i understood you. What i ment to say with constant non-turbulent wind is exactly that. To apply all the statements i said in earlier post, the wind has to have the same direction and same speed/strength through whole maneuver. Because if the wind would change, the canopy would acomodate to that speed sooner than the pilot because of way lower mass it has. it's similar, if you throw a feather with all your force away. it will decelerate in a second. but if you throw an iron ball, it will keep it's speed for much longer. same with canopy and pilot. So that's why the speed and direction of the wind needs to stay constant. And don't let me explain it in more details when turbulences apply because only then it gets [B] REALLY complicated. if by "the wind" you ment speed at which the airmass is moving over the ground, then true. when you turn, looking from the ground it will naturally seem that your speed/direction has changed. no matter the wind, if looking from the ground the direction/speed will seem to change. if you ment the relative wind - speed that the air is hitting the canopy at, then not. i mean of course the relative wind get's higher because you make a turn. but the realtive wind through maneuver is the same as it would be if the "ground wind" would be 0knots. ugh complicated... for easier understanding: If you and your buddy made 2 jumps. both jumps with same canopies. 1st jump with 20knots "ground wind", 2nd with zero "ground wind". and your friend would make exactly the same turn both times, and you would be exactly at the same position (relative to him) under the canopy of course, when he'd do a turn. the turn would look exactly the same from you perspective. relative to you, he would loose the same altitude, gain or loose same speed, and changed his direction exactly the same at both jumps. that of course would be from your perspective. if a 3rd friend would be watching all that from the ground. those 2 turns in 2 jumps would look very different... Exactly the same turns twice at exactly the same position is impossible to do in reality though. so you actually can't prove that with trying. But i hope you understood what i ment to say...

Oh jesus your mom has CDs of this stuff and you listened to 20 cds. You must have some brain trauma. I know i would if i'd listen that for more than 5mins "George just lucky i guess!"

You're right. The parachute doesn't feel the wind, it moves with the airmass, so it's completely the same for it if there is any wind or not. But that applies only in constant non-turbulent wind !!! I'm sure you'll find half of people here that won't agree with you and the other half will. Aerodynamics is a vaaast science and it ends right at quantum physics... And most people that have an opinion about this know very little of both... "George just lucky i guess!"

hmm, about $3000 with shipping and everything and you have it. With discounts and without tax you can get it for about $2500 but no less...

Cool, this is the thread for my rig too. "George just lucky i guess!"

well i'm not at least this weekend not. one team member got stuck (or something like that) in a Germany over a weekend, The other doesn't have a passport. And i don't have a car at the moment. so no Slavnica for me this weekend. Maybe next week,or sometimes in the summer. but i'll get there sometimes this year for sure! "George just lucky i guess!"

Would you mind explaining that, because i've never heard of a dirtdive with dolls. i mean how do you do it, you just put a doll where another person should be or ??? "George just lucky i guess!"

How do you guys practice a jump on the ground. whether it's a competition jump or just a training. I found it's very useful if you mentally and physically (as much as you can) prepare yourself for the jump on the ground already, even before you have your rig on. So how do you guys do it? "George just lucky i guess!"

Is anyone going to slovakia air boogie this weekend (9-12.4.2004) in Slavnica/slovakia? "George just lucky i guess!"

That's one more reason why we shouldn't get used to only one type of approach. Thanks for sharing that with us.

huh it sure does. i don't know exatly how thick 550 lbs lines are but let's say they are 3mm in diameter and 825 are 4mm in diameter 826 lbs lines are about 1 mm wider than 550 lbs lines. you have 40 lines, that are long 290 cm in average A lines probably around 270cm and D lines about 310cm (i don't know, i'm guessing according to my cobalt 120) that's 4mm*40*290= 46400 square mm with 550 lbs you'd get 3mm*40*290=34800 square mm That's 33% more drag that you get from lines. if 825 lines are only 0.5 mm thicker than 550 (which definitely are) than it's only 16.7% more drag. But we're talking only line drag not whole drag. You have a body that creates a lot more drag than the lines. just wear tight suits, and you'll swoop the same as in freefly suit with 550 lb lines "George just lucky i guess!"

psst... Not all skydivers here holds an USPA licence... And it's not so important either, it was just an idea. "George just lucky i guess!"

Great new feature. you could also add the years in sport in that mini profile, while it's added to our profiles

It's nothing much, just skysystems custom color design, but i like it. "George just lucky i guess!"

it seems a strange question to me but did you consider you actually have about 40 lines that's 22000 lbs at 550 lines and 33000 lbs at 825 lbs. And i think human body can't survive forces that are even less than 22000 lbs. So yes either lines are strong enough, i think "George just lucky i guess!"

I don't think the tighter suits are popular among experienced freefliers because of the fallrate. Someone mentioned it's easier to spread up your legs with tighter suit. that's also true, but the main reason i think is the smoothnes of flying. When you really get the feel for freeflying, you can feel that baggy suit rocks and shakes you quite a bit in the air though you don't move a bit. the fabric that flaps all over the place is the reason for that. when you have a tighter suit, it's smooth. it's not shaky any more. when you move your hand or leg, you don't have to force it to be there, the suit won't drag it away and shake it. i noticed that when videoing a 4-way. i used to fly my moderately baggy freefly suit, because it's easier to slow down if needed. But my flying and the team got better, so i started flying in closer proximity with wide angle lens. Then i noticed that the shaking of the suit is quite disturbing. i tried my RW suit (which is tight) and it's so much better/smoother. So my guess is smoothnes is the reason. but you need skills to fly a tighter suit, because suit won't help you a bit, whether you're tall, short, heavy, light,... you have to use your own body to fly...

This weekend. I call it a season opening "George just lucky i guess!"

if you are looking for FAI list of compulsory moves, then it's here: http://www.fai.org/parachuting/documents/artistic_ada_ff_2004.pdf "George just lucky i guess!"

Go to the gym "George just lucky i guess!"

and besides different format (PAL and NTSC), they don't sell every camera everywhere. In slovenia/europe, for example you can't get sony ip7. "George just lucky i guess!"

non porno, non naked: Hmm how about movie "The mask" at the begining of the movie when Cameron diaz enters the bank. "George just lucky i guess!"

I look something like this "George just lucky i guess!"
