I’m right now at a parking spot at ESSB (Bromma, Stockholm, Sweden) with the ATR after a successful landing. To my surprise, the airport is full of different aircraft (see image below) but that cannot be real traffic! In the setting I have real-traffic active but MSFS bust be showing something else! I would say this is a bug!
Since first of January there is almost no traffic at all to or from this airport. I think maybe one commercial aircraft per day is passing ESSB. There is no business to keep ESSB anymore but the politics have still not yet decided what to do with the airport. Meanwhile a lot of money is spent on an empty airport which could be used for the main airport ESSA instead.
