Here we go again...
I honestly can't believe that some people would rather have me, as a controller, speak to people in their second language that they might or might not understand properly just they might satisfy their own need for situational awareness...
Are they not realizing that in a terminal airspace, the traffic closest to them is on another frequency?... Never mind another language? I guess you expect that all terminals will now have one frequency for all their traffic so you can keep a good idea of where everybody is at? Come on!!
I really do believe situational awareness is an amazingly wonderful thing. But to claim to know where all your conflicting traffic is from the calls you hear on the air is preposterous!
So again, what are we to do? One airspace, one frequency? Because if we only allow one language in a given airspace for the sake of S.A. then this must also be done.
