Thanks for the diagrams and all of the other information.
However, I am still trying to figure out how any pilot would not realise that holding full backstick on anything other than an AN-2 (*) is a bad idea and is sure to get you into big trouble.
Is the full backstick recording actually true or is this an anomaly caused by some deeper issue ?. Did the PF *really* hold full backstick for almost 4 minutes, this seems hard to believe.
(*) The AN-2 is a special case, if the engine fails SOP is full backstick which pops the slats and causes the aircraft to mush slowly into the ground at parachute speed. - Only possible on a draggy old soviet STOL fossil.
