@ S.F.L.Y
i believe you are right that appropriate situation awareness has significant influence on security of the flying. I do not know if the pilots may/should have turned the AP earlier but i assume the rules were not broken as this would be clearly stated in the post accident report.
As a pure coincidence, the flap retraction probably caused the AP to disconnect seconds earlier than with full flaps, which gave the crew enough height to recover from the subsequent 8 degrees pitch reduction and high Vz (100 ft lost in 2.5 sec --> 2.400 fpm).
do you really believe that retraction of flaps was a coincidence? Commended 17 sec before impact while the AP disconnected some 7 sec before impact?
Are you trying to prove it was human error?
