One would want to check the trace record of elevators position at Law change with PF's first inputs in Pitch. With very low indicated airspeed wouldn't the response of elevators via FCC be extreme? relative to .82Mach? The aircraft exhibited a brisk increase in VS just at handover. Also just prior to the First Stall Warn, the PNF says: "What was that?". Could that have been a sudden reaction of the a/c to inappropriate "response"? Here, as in other areas, the CVR would be helpful, but is not published. The explanation for the comment was offered that PNF was noticing the SW, certainly, but it is not proven.
"Unusual Response-sluggish" Or "Unusual Response-Sudden"
BEA could clear this up with a memo, rather than relying on someone's best guess?
One does not expect a Stall Warn from a pull on the stick that is modulated through a computer to correct for load? Sluggish? NOT
Can this be related to Airbus OEB not to reselect A/P they released after 447?
Were they fearful the ap would "Climb Uncommanded?" with low speed inputs in this control law? Alternate Law2B? why wouldn't the ap be locked out by the system when UAS obtains? Not to mention Flight Directors....
