Hi there! Do you have an english version of this video? I think it is very important to spread it and english will be understandable for almost every one in the aeronautical system worldwide, instead of german. Thanks!
@@TheOriginalCoda Ok, I didn't tested . Here my translation: -> my english isn't the best at all It was a very experienced pilot on an airshow, who had ad accident right after takeoff. The accident investigator suspected vortex drag as root cause. They created a (computer) model and came to the conclusion that those most likely could had been the problem. (a Antonov AN-2 has started right before on the same runway, 40 seconds difference) 1:56 Those are the calculated dangerous spots for a DR-400 after a start like the AN-2 (no wind) 2:05 The calculated time course 2:17 This represents the scenario of the accident at this day. 2:25 You can see that the dangerous area is pretty exact the same as the wing-spread of the DR-400 2:35 With this Turbulences, the aileron funtionality couldn't compensate that. After those findings, they tried to reproduce the fault in a save height, but the same conditions. 4:16 If you're exact in the middle of the vortex drag, they throw the plane steep to the side ->look at the scenes right after. Those were rolling speeds, you can't control with this plane. 4:39 The measurements from the "reallife" test - massive rolling angle to almost 90 degrees. Knowledge from this accident: Even a small plane like tha AN-2 could produce big vortex drag, wich could disturb an other plane, like the DR-400 in this case, that you can't react -> especially if you dindn't expect that. Have a nice day, I hope you can learn something from that - I (paraglider pilot) have done so.
I saw that today and will answer, if you receive my message via RUclips: I flew with the pilot Gerhard Z., he was a very carefully pilot. The accident was a wake turbulence, caused by another bigger aircraft that started a few minutes before. In the flight accident report they repeated the accident situation by an experiment. The result is, that he started the plane to early, nobody knows why he did so; as I flew with him, he waited to the flight clearance from the tower. RIP 😢
Und wieder kommen unterschiedliche Faktoren zusammen, ein vermeintlich erfahrener Pilot, der vielleicht niemals die unsichtbaren und darum tückischen Wirbelschleppen falsch einschätzt. Ein nicht erfahrender Pilot hätte es vielleicht in Erwägung gezogen das dieses unsichtbare und deshalb so gefährliche Phänomen gibt.
