Norrköping Stockholm* Öckerö* Västervik*

* air risk can be unreliable and 1st-party risk is not available

Switch between ground risk and air risk views using buttons in the top right corner of the map
Change the Near Mid-Air Collision distance and the drone speed using the sliders below the map
The width of the ground risk buffer is defined by the altitude (adjusted with the slider for the whole route, or for individual waypoints in the popup) in accordance with 1:1 rule from EASA's AMC/GM to EU Regulation 2021/947.
Enable flyaway scenarios (in line with the latest SORA draft) and set the flyaway distance
Near Mid-Air Collision rate is estimated using an approach similar to the approach described in Section III.D of "Quantitative air risk assessment for a drone inspection mission along fast-train lines" paper.
