Sorry if this was asked before. Many months ago there was a documentary on French TV about one (maybe the first) A380 test flight. At some point, the pilot noticed that the a/c would accelerate faster (for a given thrust) once past a certain airspeed, and attributed this effect to "wing flexing". At least, this is what I understood. Someone else (one of the flight engineers) commented "I would like to see this in turbulence". So my question is, is this a known effect in general, how important can it be, does it need to be fixed (in software?).
Thanks
Edited: this was "A380: l'envol d'un géant" on France 2, June 12th 2005.
Edited: (to Rainboe) is it actually possible that the drag vs speed curve may have a 'kink' or even a local maximum at some speed well above the min. drag speed?
