we used to request PF call out at every action on FCU when A/P is ON just to keep PNF/PM
Probably initially a good teaching method to trap errors early (Push to give control to the computer etc.)
On the line, the calls of "Pull Standard" or "Push QNH" for the setting of the Altimeter became useless because about 50% were in the wrong direction. So we now simply say "Set Standard" etc.
Similarly, whether you push or pull the ALT knob in the correct direction is determined by whether you have OP DES or DES on the FMA with ALT Magenta showing.
