Only below 1.3Vs, if I understand OG correctly. The pitch/power settings in the supplementary UAS procedure would have kept them above that, had AF thought to provide that information.
Regardless of this factor, the DFDR trace clearly indicates that the THS position change was neither gradual nor "insidious" - it was a direct response to repeated NU demands from the SS, including the slam against the back stop.
@BOAC - the A320 has a trim limit in Alternate, and according to OG it will also halt further NU trim in the event of a Stall Warning. Why this wasn't carried over to the A330/340 is a question for Airbus.
