Fact = THS is rotated to max NU while stall warning online
Based on elevator vs THS area ratio+SW malfunction+sidestick design... The pilot error falls below 25%, first minute after AP disc

AF 442
THS nose up because that's where the stick was held....by the pilot...why? because the AFDS was commanding nose up in an attempt to "correct" the "overspeed" that was erroneously sensed...root cause, frozen pitots..pilot fixated on PFD...bad ergonomics..perhaps...incorrect pilot response..apparently so, faults in training responding to airspeed unreliable/high altitude stall?..most definitely..organizational anomaly most assuredly...lack of basic flying skills/situational awareness..yes..this latest one we have no idea, although data available shows rather large altitude excursions over a short period...not a good sign
