The technical means included under the term aeronautical communication fulfill a mission of spreading any information of interest to aircraft operations. This information is real- time information,3 and therefore is not included in the official documents published by the authorities. According to the provided service, ICAO has classified the communications in two main groups:
- Aeronautical Fixed Service (AFS): between terrestrial stations, i.e., fixed stations.
- Aeronautical Mobile Service (RR S1.32):4 between terrestrial stations and aircraft (mobile stations).
3. information of two types: communications with pilots on real time, or information prior departure delivered in what is termed as NOTAM (NOtice To AirMen), which deals with information about the flight plan, meteorological conditions, operative conditions of navaids and/or ATS routes, etc.
4. notation according to ICAO Annex 10-Vol II.
