Sweden is the same as Norway; I believe Denmark is as well.
I've always been a little curious though how that works in practice as I've been told by various pilots that there are plenty of scandis working in the "wrong" country, for example a Swede in Copenhagen. At the same time I've also been in and out of copenhagen a few times and I have heard them speak Danish with helicopters etc. Anyone with insight in how this works in practice? Is for example Danish considered "good enough" to work in Norway or is fluency (I suppose level 6 or level 5) in Norwegian something that is enforced?
