Welcome to another episode of ParaAnalysis I’m Jarek. And Jarek. Hey. Hello Guys. Today we will analyse an accident which happened this year in France. I think the wing is Ozon Rush 4 So let’s begin. As usual we will start from playing the film. And we will watch it at normal speed So everyone can see what’s happened. I hope Jarek, you can see it as well. Yes, yes. I think its a kind of Ozone Rush from what I can see. Yes it’s Rush 4. Friend of ours, Artur had exactly the same one. It the same colour. Ok. I’ll play it quickly once again. Yes. He’s on the landing approach here. He gets lift. and deformation 1 2 3 4 So the whole situation takes about 6-7 seconds. Counting from the moment of beginning of ascend. When he started going up. Now I’ll slow down the film a little bit. So we have stuff to analyse. Jarek you disappeared from my view. I hope the internet lags didn’t eat you. I got a little lag but I’m still here. For the time being I wont be enlarging this. I would like to focus on what we see here. We can see the pilot. Which is approaching landing. We should pay attention to the wind direction. Primarily the wind sock. Yes, above all else the wind sock. Because, when he comes into landing, the wind sock is moving in all directions. Now we can clearly see, when he’s moving it that direction, the wind sock begins to moves in the opposite direction Now we can see that well. That’s the direction of the wind sock. And the pilot is flying it this direction. Therefore something is not quite right. Because why did it change like that, all the sudden? I think it’s quite turbulent. And something is moving above the landing zone. Some kind of thermal bubbles. Which move the wind sock in this way, and the glider behaves totally different. and here he straightens the direction, because he wants to stay… Oooh and look here… the wind sock changed direction again. So for sure there was something moving there at that time Here the pilot is on the landing approach He’s fine tuning the direction. the wind sock turns to one side then to the other side, so there’s some turbulence moving trough And now… and how he starts ascent. He’s going vertically upwards. We can see that clearly in relation to the terrain. He doesn’t have any forward speed. At this moment he is being pulled back. And from what we can see he doesn’t let go off the brakes. so the wing is slightly braked. so play it. So Now we have a situation where at some point he leaves the lift He passed the center of the lift and the wing goes in the sink that’s why the wing shoots forward dramatically but he does nothing about it Let’s zoom in a bit I’ll zoom in he does nothing about it because the trailing edge is almost straight and only now he brakes But its already too late He should have reacted earlier to avoid front collapse what we watch it further We can see he gets quite large front collapse Almost all surface of the glider is deformed, only small bit of the left side is slightly open and the entire wing opens quite quick I would even say in less than no time even However there is a moment… Now we could see it When he pulled right brake down and stayed with his body on the right side I’ll play it one more time Now he starts going up Now the wing is still behind his back Now it starts moving forward, and right now he should start braking it, proportionally to the force, the wing is about to go pass him So the braking force should be proportional to the force of the wing shooting forward It’s easier said than done, but that’s how it suppose to be But he does it too late I think he starts to brake it here Judging by the position of his arms He gets the deformation It’s quite large, but it also opens in a flash Now we should notice he’s leaning with his body to the right and he also pulls on the right control and he also pulls on the right control maybe he wanted to pump it up Exactly as you said. I think the same. maybe subconsciously he wanted to pump it up and prevent a cravat so he pulled right control down but he also stayed leaning to the right because of that weight shift to the right he turns upwards 180 degrees to the initial direction of flight What did you say Jarek? I was just about to ask you to pause it because on this frame we can see both of his arms are up the wing overshoot in front of him again and at this point he should have burry the brakes Because yet again he’s in the same situation as previously and not we should be able to see that the only thing he does he pulls one the left brake. Can you play it Jarek? Yes exactly as Jarek said. I agree with him 100%. He doesn’t brake at all. he let the wing to go forward in front of him and he gains the speed, loading up the wing and now he begins to pull on the left control I’m pointing the screen with my finger, like someone can see my screen…;) OK Now he starts pulling on the left control and in my opinion he starts leaning left as well entry to wing over…;) Exactly, because the whole thing was swinging so the time when he begins to pull on the left control and start to lean left makes the whole thing swing even more But i think he is dong it because he wants to go back against the wind direction at all costs because when we look here the wind is blowing from the left and if the wind sock is like that, it means the wind is blowing at 4-5m/s, most probably so he wants to get back against the wind, at any cost which is OK I doubt that during whole this situation he was looking at the wind sock and analysing it, but I assume that the left side of the wing was during entire time of this situation was tight I assume he felt the wind is blowing from the left side So im betting that’s why he wanted to go back on that left side Cause I doubt he had time to check the wind sock, especially that he was rotating He didn’t have time for sure. He did it subconsciously, as you said. He felt more tension on the left side, therefore he wanted to stay on that side and go back upwind. He wasn’t looking at the wind sock for sure. But yet again he makes another mistake here he’s going back on the direction, he is lifting his arms up we can see the trailing edge is not being braked and he is allowing the wing to go forward even more you can see even his head going forward here is too late to do anything Even if he would pull both controls down its way too late He’s so critically low that if he would be lower, it would hurt him a lot, I suspect but because he had some altitude the force of impact is not so strong I hope he didn’t suffer to much but for sure it hurt Now I’ll turn of the magnifying glass I always have problems with… Oh, ok, super. with using the magnifying glass. We will go back to the beginning and we will try to tell what he was suppose to do to avoid all those problems I think at his point, where he starts going up and he can feel the wing is falling behind him he should ease on the brakes Because if he lifts his arms up a little bit he won’t be increasing the attack angle and at the moment when the wing goes in to the sinking air the wing would shoot forward as much and most probably the deformation that he would get after would be less aggressive That’s why I would lift the arms up for a while here that’s what I would do. A little bit, I’m not saying all the way up. But , a little bit. I would let the wing to fly. Only provided that I would feel the wing is behind me Now it starts to move forward so now I would brake it proportionally to the force, that the wing will try to shoot forward with He does it here too late and he gets deformation Now the wing starts open asymmetrically The left side opens faster than the right side If I would notice that, by just glancing at the wing Where is the wing. and I would notice the present deformation of the wing I would try to keep the direction of flight, at all costs So I would weight shift to the left and I would gently pull on the left brake This collapse on the right side It’s not a large size collapse because the right half of the wing it’s not hanging a lot He has half of the wing He has half of the wing, but I don’t think its a large collapse So I would weight shift to the left, and brake on the left side of the wing a bit the good side of the wing, the inflated part and I would try to keep the direction of the flight that’s not what happens here the pilot is changing the flight direction here he should have brake the wing, but he doesn’t when he starts going back under the wing he begins to brake left side of the wing Here he enforced normal wing over Yeah Now he should have grab it with both hands but yet again he didn’t do it and we can see the wing diving even further and next we see the impact as there’s no room for movement We have one alternative plan how not to let the last situation happen – the most dangerous out of all of them when in pendulum he hits the ground because subconsciously, he’s trying to go back to the flight direction he’s not braking the wing the moment when he gets the deformation and he lets the wind dive there’s not much going on because he is still quite high and the wing is not too far in front of him to be in danger of a deformation on one or the other side, or front collapse so if he would have gently brake here and went back to the previous flight direction I think he would pull it off, landing with the wind He could have, in the other hand when I look at the wind sock its more of a side wind Yup, Ok. But I don’t know he could have let go of the idea to land on the left side yes If that would have happened to me, I don’t know if I would be forcing it, to land on the left to necessarily go back upwind we landed many times with the wind during a paragliding course and changing jeans colour from blue to green therefore I don’t think its necessary to turn around and its possible to pull it off This is my alternative plan How I would act in this situation but I think we talked over all the other things I don’t have much more to add and since we are recording that before New Year what can I say Happy New Year possibly I’ll try to edit it before New Years and publish it Dear viewers Thank you very much for watching this episode As per usual Please subscribe if you want to be notified about new episodes If you liked it give us thumbs up If you didn’t like it, simply don’t react..;) Just kidding, give us dislike, or whatever Leave a thumb down, but always leave a comment with it why you didn’t like it Because that’s how we can draw some positive conclusions about what can we do to improve Surely the episodes could be shorter but since we do it spontaneously, and we are totally not prepared I just put 2 babies asleep therefore it’s difficult to do it 100% professionally but I hope you can get maximum information out of it that you want We wish you all Happy New Year I hope you will have equal amount of take offs and landings So they say 🙂 as many landings as launches Wish you only safe landings That’s that. Thank you very much guys. Greetings. Hey, Bye bye.
