Perimeter of Obstacle Limitation Surfaces
Under Art. 63 of the Ordinance of 23 November 1994 on Aviation Infrastructure (AvIO; SR 748.131.1), FOCA authorisation is required if buildings, installations or plants penetrate a surface that forms part of an Obstacle Limitation Surface map or a safety zone plan.
Obstacle Limitation Surfaces delimit a perimeter of airspace around aerodromes which must generally be kept free of obstacles in order to ensure air safety.
These geodata cover all 2D-perimeters of safety zone plans currently in force or available for public inspection (GeoIV ID 108), as well as approved civil Obstacle Limitation Surface maps (GeoIV ID 106) and warning zones for military (GeoIV ID 201) or planned civil Obstacle Limitation Surface maps.
