If you want to build or operate an airfield refueling system for flammable liquids with a flash point <23°C or make certain changes to it that affect the safety of the system, you must apply for a permit from the responsible authority.
You must have cranes, wind turbines, sky projectors and other potential obstacles approved near the airport or airfield. Businesses and citizens can obtain information from the Air Transport Department and apply for the necessary permits.
