Phoenix, Re #3637 and your #3659, thanks.
Noting that the A330 and A320 have different aerodynamic configurations and apparently software, the AF447 analogy is reasonable; but as before, without trim data THS/elevator effectiveness and capability for stall recovery remains supposition.
FDMII #3643, Re THS, AoA, etc, agree:
However, to reemphasise that the THS (trim) is a powerful contribution to pitch control and if mis positioned can seriously detract from the elevator’s ability to generate a nose down pitching moment.
An interesting logic diagram, but if this is for ‘normally expected’ switching (including power failures), it may not include law changes due to power interrupts as supposed in accident – would the design logic anticipate switched ‘power failure’ and stall in that order.
Also, the diagram apparently does not show the switching for the Abnormal Attitude Law. This appears to override both Normal and/or Alternate Laws and freezes the trim; in ‘normal’ circumstances trim could be recovered when the abnormality is corrected (aircraft tending to recover from a stall – (even in Alternate?)).
Earlier questions considered ‘if’ Abnormal Law was triggered whilst in a forced Alternate state would the trim ever be recovered; if not then stall recovery would have to be made with abnormal control effectiveness (elevator +/- THS), … and abnormal rudder trim.
… now how many of the proposed sim training exercises required by FAA /EASA will include this?
Is anyone able to verify / comment on whether an incorrect seat positon - #3466, i.e. not at the design eye positon, will affect the ability to positon the sidestick to demand a quick roll response without an inadvertent pitch-up input? Noting that in the RHS, right roll and nose down requires the longest reach.
Perhaps some real simulator tests might determine the capability (likelihood) for a range of seat positons.
Also, consider similar problems for the left seat; and how quickly an appropriate seat positon could be achieved after leaving the seat (electric seat motor?).
Anyone remember all those years ago when just after rotate a Capt’s seat slid back because of the seat rail locking failure, and s/he could not reach the centre stick?
