The loss of lift would
begin
immediately.
It looks like they used up an awful lot of runway so potentially incorrect performance and thrust setting, incorrect flap setting, chuck in a temperature inversion or changing winds too if you like and mistakenly retracting flaps instead of the gear could well be the last orifice of the Emmental.

No the plane barely took off the runway, low power setting/bad flaps. Unless you are saying a double engine failure before take off but seriously how likely is that? It's much more plausible to mess up the take off settings we have seen it many times before. But I think we will find out soon, no need to speculate too much.

Looking at the video of the takeoff roll, it seemed normal, normal rotation, normal initial climb. Other incidents with incorrect performance data or incorrect flap setting (especially flapless) resulted in an extended rotation phase, often with a tailstrike which doesn't seem to be the case here. So the flaps were probably set correctly.
This aircraft then climbed okay but then 3 things happened 1. They didn't raise the gear (maybe due distraction) 2. They apparently called a mayday for an engine problem 3. The aircraft started to sink and continued to do so until ground impact The videos and the flight path don't seem to show lateral deviation or rudder application but if they called mayday for an engine problem we've got to go with that. Perhaps the flaps were retracted early but I don't see any pitch change, just sink. As the aircraft is certified to fly on a single engine, it should have done so. That it didn't seems to indicate that the other engine also stopped developing the required thrust. Whether it was shut down unintentionally or damaged due to some environmental factor remains to be seen but my moneys on inadvertent shutdown. The most obvious answer is low power/flaps setting if the engines were weird they would have probably aborted take off. Bird strike/engine issue during take off roll after v1?

Are you familiar with balanced runway performance? Are you a heavy jet pilot? The rotation was normal. The aircraft definitely seems to have reached screen height. If so, it rotated at that position by design. It's initial climb seemed normal, notwithstanding it's duration, obviously until it stopped climbing..
Well, that's what one of the pilots reported in his mayday transmission. no way even with balanced engine performance you do not take off with no runway to spare you always leave some margin something was wrong from the start, whether that being flaps (which look like it from pics) or derated engine thrust. Something else may have happened, let\x92s see. Whatever the case that was not a normal take off roll Subjects (links are to this post in the relevant subject page so that this post can be seen in context): MAYDAY |
