If this is implemented it will be done so kicking and screaming. Operating into the likes of BCN and MAD with no one listening out and everyone talking over everybody else would be comical if it wasn't so frustrating. Situational Awareness is largely guesswork, however I doubt much, if any, consideration is given to it by Spanish operators who religiously keep to their mother tongue. Their airports, their airspace, their rules seems to be the general attitude.
