RAT 5 - yes you are correct ; totally agree with you.
Just another point I forgot to mention;there is a possibility that during the cockpit preparation setup we forgot to recycle the F/D after we had set the V2 speed in the MCP ; do you think that might have being the cause ? Do you think it might have affected the FMC / AP ?
The manual says that the F/D must be recycled on the ground after setting the V2 speed but the manual doesn't elaborate why ?
