I have a question about the altimeter setting on the PFD of Boeing 777 and 747-400.
When I change from HPA to inches, the number seems to continue showing as if HPA. And when I change the values, there is no change in the altimeter. The same does not happen on the backup display. I remember that this was possible before the last update.
Am I doing something wrong since I'm not a profound aircraft expert?
Thank you very much,
