Look at the report. The trim does nothing until the a/c is at top of climb and proabbly already stalled. It does nothing because it didn't have to - small elevator movement was enough. Only as it becomes increasingly difficult to maintain the (impossible) climb does the elevator start to move significantly NU and the THS follow. There was no lockout of autotrim. Look at the traces.
Please don't ask Bear to look at
anything, that is akin to work (not even hard work), but inconvenient. The reality of facts gets significantly in the way of today's (or tomorrow's theories...).
The obsession with the THS and autotrim is becoming tedious - the THS did what it was told to do, according to the design of the aircraft. The millions of miles covered by the A330 platform presumably are a reasonable certification of the designs basic soundness - let alone the other Airbus aircraft types of basically identical design.
