Air traffic control

Radar is a system that uses radio waves to determine the distance (ranging), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations and terrain. The term RADAR was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term radar has since entered English and other languages as an anacronym, a common noun, losing all capitalization.

thumb|NOTAM for Naval ship A NOTAM (ICAO & FAA: Notice to Airmen, CAA: Notice to Aviation) is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the flight. NOTAMs are notices or advisories that contain information concerning the establishment, conditions or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which may be essential to personnel and systems concerned with flight operations.

ENAV S.p.A. is an Italian government-controlled joint-stock company which operates as an exclusive supplier of civil air navigation services in the Italian airspace. As an air navigation service provider (ANSP) it is responsible for the provision of air traffic control service (ATCS), flight information service (FIS), aeronautical information service (AIS), and issuing of weather forecasts for the airports and the airspace under its responsibility.

Naviair (Navigation Via Air) is a state-owned company in Denmark under the Ministry of Transport that provides air traffic service, including area control service for the Danish airspace and approach control for airports in Copenhagen, Roskilde, Aalborg, Billund, Esbjerg, and Rønne. It provides flight information service in the lower airspace of Greenland and the Faroe Islands. It provides flight information service for visual flight rules and for helicopters.
