ADS-B Global Implementation and Standards
While ADS-B is a global technology, its implementation varies significantly across regions due to differing regulatory environments, airspace structures, and technological infrastructure. In the United States, the FAA has mandated ADS-B Out for most controlled airspace, using both 1090ES and UAT links depending on the aircraft type and operational altitude.
Europe follows a similar mandate under the guidance of the European Union Aviation Safety Agency (EASA) and Eurocontrol. However, European requirements focus solely on the 1090ES data link, which aligns with ICAO’s global standards. ADS-B mandates in Europe began phasing in around 2020, with full compliance required for most IFR flights.
Other countries and regions—including Australia, Canada, Singapore, and parts of Africa—have adopted or are in the process of implementing ADS-B requirements tailored to their specific operational needs. Australia was one of the first to mandate ADS-B for all IFR flights over most of the continent, driven by the country’s large remote areas.
The International Civil Aviation Organization (ICAO) plays a coordinating role through the publication of SARPs (Standards and Recommended Practices) in Annex 10. These standards ensure global compatibility and define performance parameters for ADS-B systems. Harmonization across regions is crucial for interoperability, especially for international flights.
