As far as I was aware there was no overspeed warning though - have I missed something?
The notion that the PF was responding to an "overspeed indication" on his PFD has been put forward a number of times as a reason for the pitch-up. There is no basis for the theory in any information currently available. The FWC does not send either the Stall or an Overspeed event to the ACARS, (which is, after all, a maintenance tool, not an investigative installation) and the BEA Update does not provide any information to support the notion.
