Everyone knows that wingsuits produce lift. The question is if a wingsuit can create more lift than the force of gravity pulling us down. A wingsuit will do that when it's sink rate (vertical speed) be less than the speed of the rising air. The speed of the rising air minus your wingsuit sink rate, the result is how much lift your having. The bigger the suit the better the sink rate, the better the sink rate the more chance you have to lifted by rising air. Lift and drag are forces, and forces produce accelerations, not speeds. You are confused. You are the only one confused here, Firstly I'm answering the question from "Jo" member about lift over gravity. You the sky god who claim to know everything is lacking of simple elementary physics as the other poster correctly put it. The explanation I give above is simple physics and it is exactly what happens in the real world of flying and physics applied to flying. Lauren Martins - www.youtube.com/user/gisellemartins20

Hi Jo, I forgot to mention something, that makes it easier to understand. A wingsuit no matter how big it can be, will never produce itself enough lift to win over gravity and sustain flight, not only a wingsuit but any other glider in the world, doesn't matter if a Glide Ratio of 3:1 or 50:1 like on sailplanes, all of them are gliding down, one slower with better sink rate than another, but all going down. There only 2 ways a wingsuit or any other glider will ever win over gravity and sustain flight. 1- With a motor/turbine. 2- With rising air. As wingsuits usually are gliders ( no motor ) the only way I could see a wingsuit win over gravity is when it became big enough with better sink rate, then rising air will start to have profound effect and be a game changer, but by now wingsuits are bit small for any effective lift by rising air. Together with my first post, I hope you can have an idea of how it works. Lauren Lauren Martins - www.youtube.com/user/gisellemartins20

Everyone knows that wingsuits produce lift. The question is if a wingsuit can create more lift than the force of gravity pulling us down. Not everyone knows it here, showed by many posters before. A wingsuit will do that when it's sink rate (vertical speed) be less than the speed of the rising air. The speed of the rising air minus your wingsuit sink rate, the result is how much lift your having. The bigger the suit the better the sink rate, the better the sink rate the more chance you have to lifted by rising air. It's like you're doing it on purpose. You're starting a fresh conversation at cross-purposes with everyone else and you'll probably start calling everyone else an idiot if they continue the original conversation. The entire song and dance is in danger of happening all over again. Jake you are the one always causing trouble. Kellend and I said not everyone knows it, that's not insulting or calling others idiots. The only person always swearing and insulting others here is you. Franckly, get a life and leave us having a good productive conversation. Lauren Martins - www.youtube.com/user/gisellemartins20

Well blow me down. Who could possibly have predicted that? Me and Tony predicted that, but in the world of glider design theory can sometimes be different from reality. Pointed wingtips has its obvious advantages, that's why all high performance birds like albatrosses, falcons, gliders, etc.. all has pointed wingtips for less vortex and more performance. If we can work out a way to keep the same pressure on the wings and keep the pointed long tips that would be a big gain in performance, I'm sure Tony will keep trying. Lauren Martins - www.youtube.com/user/gisellemartins20

Huh? root session? Poor me? the only poor person here is you love... makes me laugh, oh dear.... Well beauty and brain can come together in some nerdy girls, but in your case I think they forgot the brain? or both? Lauren Martins - www.youtube.com/user/gisellemartins20

Weird? I think the only weirdo here is you, your wrong as usual jumpers are, I'm not German, I'm Brazilian. Oh and by the way, yes Tony is a very open minded man and he will listen to almost anyone who has something interesting to contribute. Yes I do suggest Tony some design features, like pointed wingtips for less vortex and more performance, he did create a prototype with pointed wingtips, it flew really well but the proto has less internal pressure ( harder to fly) Lauren Martins - www.youtube.com/user/gisellemartins20

I can't believe I'm playing this game, but here we go: Post #57, you called the smartest guy in this thread an "utter idiot." (smartest in terms of aerodynamic principles... don't let that go to your head too much professor ) Please show us which post number before #57 where he insulted you. I don't kwow what is an insult for you, but I was called by the following names before the post 57. "pathetic" "apeshit" "you cant even read English" " shows you know nothing about flying" etc... Never mind anyway, I'm done with this thread, will take the advice given to me from people who actually design wingsuits. To not post on this forum. I will try not to, even if I see some bizarre misconceptions being said, tomorrow is flyable again YaY! Lauren Martins - www.youtube.com/user/gisellemartins20

In my opinion everybody here thinks you are wrong to claim that anyone in this thread says wingsuits can gain net altitude by diving and flaring. Even Robin. Then why do you keep calling other people stupid for saying so? Here are some answers from your jumper friends, when we were talking about how gliders fly hundred of miles without engine. >By Davekepka " Anything will fly provided the winds are strong enough " Just to remember we were talking about flying no where near a mountain or ridge. >By kellend " any glider can do it starts with an excess of kinetic energy that it can trade for potential energy. No thermal needed to fly " >By vitriol "Very strong winds could produce that kind of lift, but then it wouldn't be a thermal" Lauren Martins - www.youtube.com/user/gisellemartins20

Your first post in this thread LOL My opinion has changed after Robin's post, I was a bit naive. It did look like a thermal very much and a strong thermal can do that on large suits, but it wasn't the case on that video, I wasn't there to actually knows perfectly what happened. Robin explained it well. Lauren Martins - www.youtube.com/user/gisellemartins20

Giselle Martins, mistress of flight, physics and revisionist history But if you now accept that wingsuits can briefly achieve climb rates by converting speed to lift, are you going to accept that everyone you disagreed with in this thread was right and you were wrong? Jake like Lurch love calling others names when they are unhappy and using the word "we all" "everybody here" instead of use "I" "in my opinion" Not everybody here disagree with me, the word you and lurch love "everyone" is not applicable. Unlike you, I knew since teenager years than any aircraft with wings given enough speed will have a momentous climb with speed to lift. Lauren Martins - www.youtube.com/user/gisellemartins20

Oh Lurch.... The one who contradict himself many times before here. The one who love to put words in others mouths The one who insult me because English isn't my mother language. The one who Tony dont give a damn but keep bothering him, poor Tony. The one who insults anyone who disagree with him, ( so am i as you just claimed) Firstly I didn't insult anyone, if I did was because I was insulted a first? but nothing compared with your insults anyway, like just you did now about my English? its not my mother language so writing mistakes are fine. I speak 3 other languages, do you speak any other language besides English? Secondly I'm very much agree with Robin, he seems to be one of the few here with politeness, right input and know how non powered flying words. now you Lurch? I laugh...

Another one who post without reading previous messages. All I've been saying the entire topic is that the latest largest wingsuits can gain altitude even momentaneously with thermals, ridge soaring or with speed to lift like on the video in china. We were discussing "how it climbed" not "if it climbed" Actually this whole thread you were pretty consistent about how wingsuits DO NOT gain altitude with speed but thermals and ridge lift... I did read every post in this thread and you only changed position after someone that was there descibed the situation we all already knew to be true, I suggest you don't call anyone here ignorant till you have some wingsuit jumps under your belt. Nope, actually the entire threat was about some wingsuit jumpers claiming that the way non powered aircraft gain net altitude is by speeding or speed to lift and as we all know its not the case, and I was explaining how we actually gain altitude and some of your fellow jumpers keep posting videos of planes with engines off speeding and doing speed to lift and saying themselves how the plane gain altitude and that there were no need of thermals, if you read the thread you would know they claim it, and no at that time we were no talking a small gain but how actually how we gain altitude for flying.

Well, there is ridge lift and wave lift too. LOL... Good eye, Professor Nitpicker. I saw that after it was too late to edit. How'd my paper grade out otherwise? 44 Don't know that I'm qualified to answer that. After all, Lauren/Giselle claims I'm not a glider pilot despite what is written on my FAA issued pilot certificate, and that I know no physics despite having a PhD in the subject. Robin, This Kellend "Dr. knows Everything" claim to be a skygod but he can not answer simple questions about gliding, nor either answered what is his longest flight on his glider and his paraglider and the IGC file to prove it of course. You are a registered pilot and? that doesn't mean you are experienced and knows everything. period. Lauren Martins - www.youtube.com/user/gisellemartins20

Well explained post Robin,I agree with every single word. You were there most of us weren't so the only thing we can do is discuss about it based on a video only, which is not enough. Its really amazing what these new large suits can do, hopefully will get even better. Even although I Agree that on that specific video the small gain in height was due a long fast dive and flare as Robin described I do believe that is perfectly possible for a slim person in a very large suit to be lifted momentanously by a thermal when they fly trough it, same is valid for flying near a mountain with very strong winds ( ridge soaring). Lastly Its clear that some guys here knows that non powered aircrafts need thermals or ridge soaring to fly and that dive and flare is not the way upwards, but I met and spoke with many jumpers who fly suits and believe me when I say a lot of them has no idea how a non-powered aircraft flies and they want to apply the same laws of powered flight to themselves flying a wingsuit, when a wingsuit is a glider ( no motor). The reason I'm so passionate about making sure that the wingsuit community knows clearly how non-powered flight works, its because we are in a stage when suits have enormous potential, they are becoming glider and if you know how to use gliding knowledge and apply this to your jumps or base jumps you could explore all its potential and stay in the air much longer. Once again Robin thanks for taking time and coming here and explain to us what happened there, as you were there. Cheers Lauren Lauren Martins - www.youtube.com/user/gisellemartins20

Moderator this jakee user has no respect, can not dialogue without swearing and personal attacks, I feel insulted as pilot and as a person, I'm a well respected wherever I go, and this is not the first he does it, disrespecting even what you asked. Lauren Martins - www.youtube.com/user/gisellemartins20

And precisely no one is claiming otherwise, which has been said here about 20 times already. The gain everyone but you is talking about is relative to the lowest point of the "dive". Right, so there is a mighty thermal that's always there, in the exact same place, on multiple jumps at that event? http://www.youtube.com/watch?v=gMkvPDd-8wE http://www.youtube.com/watch?feature=player_embedded&v=VigfXe1vhYg And it also for some reason only affects the jumper, but not the smoke? And entering it always for some reason corresponds with a change in body position? http://www.youtube.com/watch?v=6Tu5Cyw8xlI&feature=player_embedded Interesting valid points you have, it is possible to a place have a residential thermal given very specific conditions but it is unusual. I can't see the bottom of the mountain so I can't say if it would be the case or not. The smoke did move a tiny bit upwards but yes not as much as it would in a strong thermal, so your point is valid there. I didn't see the other videos before, on the new videos you posted I can see that his body position did change, so there is a flare factor there, your correct. What amazes me is how he manage to climb so high for so long ( 6 )seconds with just a sharp dive and flare? I wonder what was the wind speed that day? was the wind direction head wind at take off? anyone knows? because a strong wind hitting the mountain will create a strong lift band, not strong enough to give him sustained flight but strong enough to help him gain height on his flare? The fact is that is hard to believe that he manage to climb all that height all that time just with a flare without any help of a thermal or ridge lift, unless the latest largest suits from Tony are REALLY that big! Lauren Martins - www.youtube.com/user/gisellemartins20

Finally a First educated post coming from a jumper without a swear word or personal attack :) Mark as I said before I don't think that gain of altitude on that video was because of a dive and flare, firstly because there is no sharp dive on his glide path, secondly because he kept climbing for 6 seconds and for several meters, this amount of time climbing and height is simple not possible just by diving and flaring, only a thermal could be strong enough to lift him like that. Lauren Lauren Martins - www.youtube.com/user/gisellemartins20

No, because doing that you always end at the same height or lower than where you started the "U" dive. So that's not gaining altitude, that's keeping the same altitude or losing it. Small Momentaneous speed to lift is not considered gaining altitude. Lauren Martins - www.youtube.com/user/gisellemartins20

I'm sure every single jumper here knows that doing that on a wingsuit is not possible, but read back the entire topic and you will see a few have wrote and posted videos of gliders and planes ( with engine off) diving and flaring and they said how doing that is the way to gain altitude and that there were no need for thermal for non-powered flight. examples like the tail exit was given, etc... makes laugh hard really LOL! If you don't believe me, read back the topic and check it yourself. Lauren Martins - www.youtube.com/user/gisellemartins20

You are dumb as shit. You really think that anyone here believes you can dive and flare a wingsuit across the countryside? A Phd calling another pilot dumb shit? unbelievable you are! "Speed" " dive and flare" if you believe or not that is exactly what I heard from wingsuiters. period. That's how some wingsuiters believe non-powered manage to fly hundred of miles, they don't know even what thermals are. Maybe you can understand it as simple as I do as we are both pilots, but believe me, some wingsuiters have absolutely no idea of how non-powered flight works, and the worse bit, they think they already know everything like yourself and if you try to explain to them how it actually works, they do what they done on this topic. incredible really. Lauren Martins - www.youtube.com/user/gisellemartins20

No shit Shylock. Do you seriously think that's not how he thinks it works? Yes, because every wingsuit jumper I met in person think non-powered aircrafts gain altitude and fly hundred of miles by "speeding" or " diving and flaring" wingsuiters for some reason has this stupid misconception, and they always use the tail exit climb as an example to explain how they think gliders fly to clouds etc... Just like a dozen have given this very same example here several times. wingsuiters are flying a glider without motor, powered by gravity but they still think they are flying a powered aircraft, because they always want to apply powered laws to explain how their wingsuit ( glider) flies. its unbelievable. Lauren Martins - www.youtube.com/user/gisellemartins20

Another neanderthal incapable of understanding simple physics and flying, giving the same old tail example. Again for the 21th time, not everything that you see is how you think it works. He had a momentous small gain in climb over the plane because the plane gave him enough energy airspeed to climb, but that is NOT how non-powered aircrafts gain altitude, they need columns of air, thermals to lift them. Without that planes energy that suit wouldn't have that climb. Lauren Martins - www.youtube.com/user/gisellemartins20
