Clandestino
Anyway I don't think that trim played significant part in the grand scheme of things and whether A330 THS is a) too powerful b) barely meeting certification requirements c) somewhere in between is for aerodynamicist to answer.
The control power of the THS is not what we are interested in so much as the effect of trimming all the way up to the stall. Test pilots avoid doing this for good reasons.
It is difficult to get the aircraft out of a stall when it is trimmed right up to the edge of the stall or beyond, particularly with a THS type aircraft.
Do you really think that just because the aircraft functioned just the way the designers set it to do in some obscure corner of the envelope, it is perfectly OK?
