LFV is working to reduce the number of people exposed to aircraft noise by, as far as possible, lead the planes in the flight paths located outside urban areas. Green approaches, implemented at the Stockholm-Arlanda, also reduce the noise as the aircraft hang-glides over a large part of the approach. If you are disturbed, turn to the airport to present your views. It is the airport that holds the environment permit. They often have a routine in managing these cases and can also guide you further if needed.
