Air traffic services have been established at more than 50 airports in Norway, in addition to offshore installations and area control centres. The air traffic services are provided to the regional airports (short take-off and landing airports) and offshore installations, in addition to air traffic control services at larger airports and area control centres. The staff conducting this service comprise of air traffic controllers and aerodrome flight information (AFIS) operators.

Norwegian civil aviation is completely dependent on air navigation equipment. Such equipment includes for instance radio beacons for navigation between the various aerodromes, instrument landing systems, radio, telephone, radar, and satellite-based equipment. The staff responsible for maintaining and procure this equipment is engineers and technicians with comprehensive special skills.

For pilots it is important to have access to meteorological information. This includes both current meteorological information and meteorological forecasts. Equally important are special reports on phenomena such as super-cooled rain and severe turbulence. The forecast service for civil aviation is provided by the Norwegian Meteorological Institute which uses weather observations made by air traffic service staff at all aerodromes to prepare forecasts which pilots may use to plan their flights.

The Section for Air Navigation Services is responsible for establishing provisions which regulate these services and which require that all equipment used are safe. The CAA shall also ensure that everyone working within air navigation services has the necessary qualifications. The oversight is maintained through monitoring and inspections, in general there will be two inspections of each aerodrome during a 5-year period. After an inspection a report is written presenting the findings and possible adjustments that have to be made to improve aviation safety further.

Many of the provisions which regulate the air navigation services are based on international standards, which are to contribute to a safety level in Norway that equals the international standard. The CAA is therefore represented in international agencies such as the International Civil Aviation Organisation (ICAO) under the UN, EUROCONTROL, the European organisation for air navigation safety, and Single European Sky, an EU project which aims at increasing aviation safety and capacity in European airspace. In the section for air navigation safety there are 13 inspectors with experience from air traffic services, air navigation services and meteorological services.
