All the above provisions are applicable to all flights operating in accordance with instrument flight rules within the Single European Sky airspace

Time Limited Extensions
Operators of aircraft with a first certificate of airworthiness issued before 7 December 2020 shall comply by 7 June 2023 with the ADS-B Out and Mode S Enhanced requirements, provided that:

  • those aircraft have not benefitted from any Union funding granted to bring such aircraft in compliance with the requirements.

For the time being, this retrofit programme does not have to be submitted or approved by EASA.

  • they are being flown to undergo maintenance;
  • they are being flown for export;
  • their operations will be ceased by 31 October 2025.
