3. European ATM Network (EATMN): systems
EATMN is subdivided into eight systems:
1. Systems and procedures for airspace management.
2. Systems and procedures for air traffic flow management.
3. Systems and procedures for air traffic services, in particular flight data processing systems, surveillance data
processing systems and human-machine interface systems.
4. Communications systems and procedures for ground-to-ground, air-to-ground and air-to-air communications.
5. Navigation systems and procedures.
6. Surveillance systems and procedures.
7. Systems and procedures for aeronautical information services.
8. Systems and procedures for the use of meteorological information.
