I see no reason to doubt the accuracy of the simulator used by Bechet. He gained less than 10ft height in the five seconds after he went to full throttle and full back stick. That is equivalent to less than 1 kt of airspeed. In the accident flight the wind was light and variable (5 kt +/- 2kt headwind component), and in those last few seconds the airplane entered the lee of the forest. Those wind varations were evidently not represented in the simulator.
P.S.
Just before hitting the trees, the DFDR recorded RA was 24 ft, possibly even less because the recorded values are rounded to the nearest 2 ft. The
average tree height is reported as 12 m (40 ft).
