GY,
Secondly, how does that tie into the BEA reports of the speeds dropping below 60kts and then recovering?
Some have speculated that the RHS airspeed oversped. Since that side is not monitored by the DFDR, there is some possibility that this happened.
I personally don't hold to this notion, but with the information we have at the moment, it is still a possibility.
I tend to believe that the PF accidentally got some back stick mixed in with his lateral control efforts, causing a net nose up input over time.
