Quoting Neptunus Rex:-
Not quite. Manual pitch trim should have been available in both cases.
I don't think so, Neptunus. Don't forget, 'autotrim' was still operating; and I don't think Airbus pilots have the option of turning it off? So if they'd wound the trimwheel forward to reduce the huge (13-degree) 'up' angle the systems appear to have imposed, the autotrim would presumably just have wound it back to 'Square Thirteen' again?
