Not only Hableshiem nor AF447 then the China Air? Where trim was wound on not understanding that the autopilot was counteracting said trim and after the autopilot disconnected the aircraft stood in its tail and stalled iirc.
Another disconcerting tale whilst sitting on a mountain waiting to paraglide was from the skipper who had recently declared an emergency and done a quick circuit at LHR after he had started loosing all hydraulic systems according to his TV screens to subsequently discover it was a single computer fault. Now forgive me for being a dinosaur but the now junk that I flew generally had completely separated control systems and my biggest worry was the three adjacent hydraulic lines in the main gear bays in the DC10 although unknowingly Douglas had routed them around engine 2 as well with dire consequences.
there is no such thing as alternate law or normal law on the A30B and A306/310. Actuators and cables, basically the same as on your DC10…
