Gums, What you wrote is correct for Alt1 Law but not for Alt2 Law. Alt2 Law is roll direct, i.e. aileron deflection proportional to stick deflection.
Organfreak, There is a reason each transducer on the stick has its own control mechanism, it is redundancy. That redundancy undoubtedly carries through in the software design of the "Bus" so that it can recognize a bad transducer, but don't ask me details because I don't know. At this point, all I know is that it would be extremely out of character not to cover that potential problem.

Dozy, I agree with this summation

TTex, he was essentially reversing his roll input every two seconds. Maximum control input pretty well corresponds to maximum wing down. Just hanging on is probably as good a description as any. Over time the intensity of his inputs begins to decrease as he began to get the "touch".
PF was definitely driving a lateral oscillation by means of his excessive control inputs. This period where he is struggling with roll is when the aircraft became committed to a nose up attitude.
So why didn't PNF at least coach him back on altitude? All I can conclude is that both of their scans were in the toilet. "GO Down" , YGTBSM.

Thanks Rudderrat. I just wanted to be sure. No lateral pulses then in Alt2.
