"pilots will be banned from European airspace" ...lol, like the American, Canadian, UAE and Australian pilots that are outside of Europe and can't fly in European airspace! ...O wait they can!
The European Union cannot regulate in this area! The aviation treaties that aviation runs on are all from pre-1958, a significant date as any international treaty signed before 1st January 1958 is more superior than European Union law, as laid down in the Treaty of European Union article 351.
Aviation existed before the European Union and will be around a long time after its forgotten.
