There seems to be some departure from 'actual' parameters in that sim (as expected), as you describe a pitch down below the horizon with full THS and power. 447 managed to hold a high nose attitude in that situation. How much stick effort was required to hold the nose down against the thrust couple? Full forward, half?
I should clarify, to calm DW's fevoured brow, that I do KNOW the A/P would not 're-engage' - I was attempting to transfer the apparent FD 'logic' to the A/P as an example, in my opinion, of misguided design. After all, we do have enough examples of the AB A/P ACTUALLY causing a dramatic 'uncommanded' climb.
