For the A330, according to
A33Zab, there is no such electric limitation.
After re-reading
his post, I can see he had already produced a possible reason for which the THS did not reach the max deflection.
But once again, it was the BEA job to develop that stuff ...
If I understand A33Zab post (read between the lines ... ) maybe he think at the law (another!) "Unusual attitudes" who inhibit the autotrim system
Nevertheless .. nowhere in the FDR extracts of the BEA is show a trace of this law been triggered ......
I can be wrong ...
