Hello Marianna,

In the EASA/EU environment, there is currently not a mechanism like the FAA's Privacy ICAO Address (PIA) program that allows operators to limit the availability of real-time ADS-B position and identification information for privacy concerns.

European regulations mandate the use of ADS-B and Mode S transponders for aircraft operating under IFR/GAT, with compliance required since June 2020 for various types of aircraft. The regulations focus on improving safety, efficiency, and interoperability across the European airspace but do not provide explicit provisions for operators to limit the broadcast of ADS-B data for privacy purposes.

However, privacy concerns related to ADS-B have been recognised globally, and ongoing discussions and technological developments aim to address these issues while maintaining the benefits of ADS-B for air traffic management and safety.

For more detailed information on the regulations and requirements, you can refer to the EASA website and specific regulations such as EU Regulation No 1207/2011 and its amendments.

Thank you Benjamin
