1100 years ago Europe belonged to the Vikings - today ATC language should be scandi!
My situational awareness at CDG is less due to dual language. In Scandinavia we keep it english (most of the time), even at small airports. We, too, try to protect our own language, but everybody speaks at least 2-3 foreign languages. It's increadible unprofessional at an international airport as CDG to speak french!! I otherwise like the way CDG ATC do their job.
