It seems very unlikely the CC is going to go along with this if 2 minutes earlier they had a friendly wave and chat while the pilot went off to the toilet and then remaining flight deck crew pushes the nose towards the ground while insisting that the other pilot not be let in.
"pushing the noise towards the ground" might be nothing more sinister than the required swift'ish response to a TCAS RA.....how good is the average CC members knowledge of the FCOM 1 and QRH?
Now if the suggestion is that there always has to be two rated pilots on the flight deck we might be heading towards common ground.
