A question regarding AIR FORCE ONE or any xxxxx ONE aircraft. If I understand correctly, standard procedure for any aircraft carrying the country's leader (President or Prime Minister) carries the callsign appended with ONE, such as CANFORCE ONE.
Now, what happens if the US President's aircraft is not carrying the President? Would it still be addressed as AIR FORCE ONE? What happens if the President was on a different aircraft? I'm not asking to cause trouble, but curious how the whole ATC system works. I just realized I posted this in the wrong forum... oops - can somebody move this?
