"Because it related to international air transport the ICAO call sign standard includes the nationality character(s)." Errrrr, Jim59, when a United Airlines 777 is approaching Heathrow (or indeed, anywhere) you surely don't believe that their callsign is "November Alpha Bravo Charlie Delta" do you? Because it most definitely is not. Nor do the pilots include any aspect of "the nationality character(s)" - they would call "United 123 Heavy" (or similar). Conventions, eh? Who knew?
