Of course comparing with flying over scandinavia, germany, italy, holland etc has no influence on this matter cus they dont have that right, evrything has to be in english and trust me most of those nationalities would love to, but theyre not approved, so in this matter we should think in why before opening our peaks
They have exactly the same right. Let's take, for example, Finland where Finnish and English are the accepted languages in the world of aviation: when flying from/to EFHK the pilots and the controllers speak always English, of course there are sometimes some PPL Cessna-pilots speaking Finnish (but I think the reason is that they don't have an English R/T-rating). I've never heard a controller or a pilot speaking Finnish (except some private pilots) when there's a non-Finnish pilot on the same frequency. Finnish is used at smaller airports but when a non-Finnish a/c tunes the same frequency, a smooth change to English is performed.
