Yes, while in alternate law (and with the AA over 40º, abnormal attitude law) auto-trim is disabled. However my comment was in regard to the scenario Yipoyan referred to with the Chinese A300 Go-Around. In this instance, had a nose down input recovered the stall, and thus normal law returned, the auto-trim would have moved nose down.
Sorry I thought you were referring to this case.

What does it take to have the FC system return to normal law? Does the system do that automatically after it has decided that the AS sensors were previously declared as faulted, or does it have to be reset manually? Is there any indication that the system returned to normal law or that the autotrim system moved the trim from 3 to 13 degrees?
