lennonjohtopalvelut

Lennonjohtopalvelut, or air traffic control (ATC) services, are the set of services that ensure the safe, orderly, and expeditious movement of aircraft through airspace and on the ground at airports. They are provided by an air navigation service provider (ANSP) and are regulated by national and international authorities to maintain safety and efficiency.

In Finland, lennonjohtopalvelut are delivered by Finavia, a state-owned company responsible for air navigation services and airport operations, under the supervision of Traficom, the Finnish Transport and Communications Agency. Finavia handles en-route control, approach and aerodrome control at Finnish airports and coordinates with other European ANSPs within the broader European air traffic management framework.

Core functions of lennonjohtopalvelut include air traffic control in en-route and terminal areas, aerodrome control, flight information services, and alerting. Controllers issue clearances, maintain separation between aircraft, and coordinate with pilots and ground services to manage weather, safety, and efficiency considerations. They work to minimize delays while ensuring safe operations across national and international airspace.

Operations rely on a mix of surveillance and communications technology, such as radar and satellite-based surveillance, radio communications, CPDLC, and weather data. Procedures follow international standards set by ICAO and European frameworks like SES and EASA, using standardized phraseology and sectorized airspace to optimize routing and capacity.

Training and qualification for lennonjohtopalvelut involve extensive initial instruction and licensing by the national authority, followed by ongoing proficiency checks. Safety management, incident reporting, and regular audits are integral components of the system.
