Sorry, Doze, I answered you in the other thread. Briefly, Airbus itself warns to turn OFF A/P with UAS. If it is latched off by the computer and cannot be reselected, why does A/B warn against its "re-selection"? Why bother, if as you say the A/P is shut down completely and forever until ground maintenance? The FD is obviously not treated in the manner you suggest, it came back on, in different modes, several times. Are you sure you know whereof you speak? No offense.
