Air Navigation Services (ANS)
Air navigation services is the term applied to the bundle of services provided to aircraft to enable safe and efficient flight from one destination to another.
Air Traffic Control service
Air traffic control service is a service provided by licenced ATCOs for the purpose of:
- preventing collisions:
- between aircraft, and
- on the maneuvering area between aircraft and obstructions; and
- expediting and maintaining an orderly flow of air traffic.
Communication, navigation and surveillance service
Communication, navigation and surveillance service is the technical backbone of the Air Traffic Management system. It is responsible for planning, installing and maintaining the technical systems used by ATCOs to provide air traffic.
The communication service is responsible for the voice and data communication systems used for air-ground communication between pilots and ATCOs and communication between ATC units and other relevant stakeholders.
The navigation service is responsible for the ground installed navigation equipment which facilitate the efficient and safe navigation of aircraft in the air. These equipment continuously transmit radio signals which help aircraft determine their location in space regardless of the weather conditions. Navigation equipment is critical especially for Instrument Landing Systems (ILS) which enable aircraft to land based solely on signals transmitted by such equipment.
The surveillance service is responsible for surveillance systems which provide ATCOs with a visual overview of the aircraft flying in the airspace under their control. The traditional surveillance systems such as primary and secondary radar systems are still the most widely used systems by air navigation service providers. However, more recent surveillance systems which rely on satellite signals, such as ADS-B and MLAT, are increasingly being deployed in European airports.
Aeronautical information service (AIS)
The aim of the aeronautical information service (AIS) is to ensure the flow of aeronautical information/data necessary for safety, regularity, economy and efficiency of international air navigation. AIS is responsible for collating/assembling, editing, formatting, publishing and distributing aeronautical data to pilots, ATC units and other stakeholders. The aeronautical data, depending on the nature of the information, is published and distributed via these main documents:
- Aeronautical Information Publication (AIP)
- Notice to Airmen (NOTAMs)
- Aeronautical Information Circulars (AIC)
- Pre-flight Information Bulletins (PIB)
The meteorological service provides aeronautical weather information to airspace users, ATC units and other relevant stakeholders. They provide both weather observation reports such as METAR, SPECI, etc., and weather forecast reports such as TAF and SIGMET. The meteorological service also provides warnings and other significant meteorological information concerning meteorological conditions that may affect flights on the ground, airport facilities, airport services, and safe flight services on the runway.
