Read and reread the report and still I find something troubles me, the initial reaction timing. According to DFDR elevators were moved by PF at T3, this being 3s after the failure and 1s after the AP disconnect. By this stage, yes, the PFD had risen to 13.7deg PU, so a very rapid pitch (indication) excursion, significantly greater than would be seen (and believed) in normal ops.
Nevertheless, why did PF respond so quickly ( 3s is quick) without ANY somatogravic change of state? I am puzzled by this and it is not explained directly in the report.
It worries me to think that it is within the scope of normal pilot behaviour to react instantaneously to a major change in the displayed flight trajectory without 'feeling' it also. Let me be clear, this is not about som. Illusion or recovery from UA.
