So, you're saying that in a busy, congested ATC environment, having EK 927, EK 97, and EK 9927 on frequency at the same time could not POSSIBLY lead to confusion and mistakes unless someone was being unprofessional?
Actually in America that is quite easy, " Emirates Nine Twenty Seven, Emirates Ninety Seven, and Emirates Ninety Nine Twenty Seven". This fixation with reading call signs as single digits is half the problem.
If I am EK 151 right behind EK 15 I sure as heck don't say "Emirates One Five One", I would instantly become "Emirates One fifty one" if he is transmitting as Emirates one five. The uptight people who insist on standardized phraseology at times like that need to loosen up a little.
