R650 times a couple of thousand is going into the millions. A lot of dough to be made out of chatting to someone for thirty minutes. But it will eliminate a lot of confusion and bring a sense of order to the skies, such as:
Pilot: Aircraft X declaring an emergency.
ATC: Please state the nature of the emergency.
Pilot: We've lost an engine.
ATC: Due to the double meaning of that statement we will not deal with the emergency at this moment. Please attend an english proficiency exam and then get back to us.
