France is a country of compromises, you will never get the things change from one day to another.
For instance using native language has good operational & safety arguments, as well as using common language has.
This topics highlights that runway incursion is the main danger we all face
, to reduce the level of stress of our non-french speaking pilots flying into CDG, we could just change the terms of "autorisé à l'attérissage" & "autorisé au décollage" & "autorisé à traverser" by "cleared to T/O" & "cleared to land" "clear to cross", this 3 little sentences would made it clear for everyone, as for the rest, approach for exemple, it is an absurdity to try to get a situation awarness in such a hight density environment
(it is dangerous and it is not a pilot's task).
To avoid mixing french&english this could end into speaking english ONLY on TWR frequency, as communications are short & easy & usually standard at this stage.
Would every one be happy by that solution?
On the other side, it would be helpfull from native english speakers, to speak proper english and use good DICTION on frequency, thanks for thinking of others trying to pick U
Happy landings
