As a beginner this is quite frightening to watch. It didn't look a like you did a lot wrong but it's hard for me to tell?! I wonder if an EN A wing would handle it differently or if the incorrect inputs would have the same effect.
Hi Tommy G, Yes to the question on an A wing I could have had it under control and not at to pull the pin. 😅 This was my last day of my SIV I was so keen on getting the Sat's right. When Lee asked me to do the wingovers I just did think to hard on just went for it. SIV can be very tiring so you need to be focused at all times. The one thing that got to me is waiting to take off I was up on takeoff for two hours before going out. 🙄You switch off at this point. Stay safe. Rob.
Timing is cruicial for wingovers. It won't look like anything was done wrong unless you've been properly trained on how to do them. This is why it's a good idea to only start doing them during an SIV. If you aren't performing these maneuvers you won't deal with any of what's happening here.
Damn, that's scary. It looked like after the initial collapse you went to stop an autorotation, the wing was already back from the swing though so it stalled, surged, other side collapsed, then went into an autorotation with twisted lines? So scary. Am I right that the wing stalled when you corrected the first collapse? Is that normal in a wingover? I guess best move would be to lean against the autorotation but keep hands off the break until the wing surges?
Nick I think your sequence of the cascade is correct, and besides the outside collapse (which is to be expected when learning) the critical error was over- braking the flying side when swinging under, which lead to the whip stall/ surge/fail to catch the surge/ getting flipped head over toe almost into the wing. Someone can correct me if they disagree, but I don't think the instructor was doing him a favor by telling him to weightshift/ opposite brake right when he was dropping into the bottom of the pendulum. Weightshift yes, but when you're swinging under like that, you need to let the open side fly. One nice trick is keeping your elbows just outside the risers so that if you take a collapse, you can instantly hook the elbow on the open side riser and keep your body weight centered or leaning towards the open side.
I think the main mistake was going too high too fast. You need to slowly build up energy. If the instructor would have told him to go hands up when the collapse happened, the glider would have flown fine. Maybe if he would have told him which side to break it would have worked but too many times pilots overcorrect or pull the wrong side (Because twisted/disoriented) thus (At least with EN A/B gliders) its better to just go hands up most of the time
The initial collapse was due to pulling the brakes late and not having enough outside brake. The next thing to happen was overpiloting the collapse. Should have just gone hands up. That caused the guy to shoot forward really hard like that. The third cravatte was really big and looks like it would have been really complicated to fix. Countering the autorotation should have been done. With brakes. At that point if the autorotation was controlled, stalling may have been an option if the pilot was very experienced with them. If not (to either of those), the reserve was really the only option left.
what a stupid and dangerous wing...... i tried the chili 3,4 and 5 and I have to say that the 3&4 are dangerous wings and shoudn´t be on the market....
