Not sure how this even generates a 2 page thread. Airbus has always been PM sets everything if PF is flying manually. After a while you don't even think about it, both are in the loop and 2 experienced pilots will intuitively set the FCU after a radio call and be listening too/for the confirmation from the PF while doing it. We all know we could do the whole thing ourselves, thats why there are 2 of us on the flight deck, but whilst both are working, both need to have a common situational awareness of the moment.
