My understanding of mm43 re: "surprise" is as a general comment, and not related to weather, necessarily. My belief is that A/P trip out was a "surprise", whether due to unreliable data (A/S) or a sudden onset of turbulence, that exceeded the A/P's programmed parameters. Any turbulence producing reactions in A/P of beyond 45degree roll had to have been sudden, or pilot would have started manual flight prior, no? The cascade of bad news seems like a sim ride nightmare, presenting warnings that could be solved only by reference, and Alternate Law II removed protections that cannot be regained until landing, so the pilot was thinking of a very long flight in either direction, should he even be successful at maintaining safe level flight. I cannot envision any other response than that of surprise. imo
