The pre- and post-stall aero data have been obtained from analysis of the DFDR data. Within the normal flight envelope these match authentic Airbus data. Outside that envelope the verification consisted of running the model through the recorded time histories of pitch and N1, and comparing the resulting 'model' trajectory (the violet line in Owain's graph) to the actual DFDR trajectory (the yellow/red line).
