Quite honestly, using my native language in my home country for ATC would reduce my mental capacity, situational awareness and speed of communication. Simply because i always have to think about the correct phraseology which i haven’t used in over 25 years (and i have been based in my home country nearly all that time).
And of course there is the pesky issue of not being able to get full situational awareness and a correct mental model incase of multiple language use on frequency. Had that demonstrated once in MAD of all places, an Iberia (spanish communication) and us (english) under the control of the same ground controller got a conflicting clearance that could have resulted in some bent metal at the next intersection. It was easily solved by our colleagues in the Iberia by switching to english and querying that clearance prompting the ATCO to reply in english as well assuring that both crews and the controller had the same mental model. In the air conflicts are not always as easy to see and to solve, where dual language use is common.
“French ATC“ and „Spanish ATC“ are the number one threats during the TEM discussion in the briefing in those places.
In the words of the Bard....'Nailed it'.
