Stockholm Arlanda Airport is a three-runway airport (Figure 1) located in the Sigtuna Municipality of Sweden. It is the largest airport in Sweden and the third-largest airport in Scandinavia. In 2017 it carried approximately 27 million passengers.
The airport has an environmental permit containing a number of terms regulating the airport’s activities. Among other terms it is regulated how the traffic should be handled when it comes to flight paths, use of runway combinations, noise levels, regulations, noise insulation, etc. The environmental permit has been determined in the environmental court.
Additionally, Stockholm Arlanda Airport annually compiles a Noise Management Plan (NMP), containing all activities regarding aircraft noise, highlighting on what the airport will work on during the year. The activities are spread over different departments of Swedavia, which is the airport owner.
