@OG:
No apology necessary. Regardless of where your info came from, my experience in the A320 sim (presuming that the systems behaviour was accurate) showed that NU trim was indeed inhibited shortly after we began the NU SS input. Whether that was linked to the SW or a feature of that control law on the A320, the trim nevertheless stopped of its own accord.

With respect, how does that work? Regardless of the THS position, Bonin was still pulling NU fairly consistently all the way down. They're at about 28,000ft at the point he releases the SS from the back stop - even with that much to play with, it doesn't leave much time for recovery...
