Effectively Air China does not understand a basic english... and plus they should have said "say again " if they do not understand very well. But they prefered to repeat wrong instructions.
But I am french and when I heard this controller, I think he was a little
arrogant and he was not very
tolerant.
Just listen his stupid joke at the beginning of the video!! that was not a good phraseology!!
and plus he is american, it is SO easy to english or american speaker to not learn an other language just because it is the language of aviation!!
Well I would like to heard for example this controller to come here in France and speaking french at the controll
