The European Commission has published a set of standardized rules of the air (SERA) to harmonize European requirements with International Civil Aviation Organization (ICAO) regulations and recommendations with the aim to enable a “high uniform level of aviation safety in Europe and globally.” Specifically, the new and revised rules “clarify, improve, and facilitate the implementation of SERA requirements, and bring operational and safety benefits also in the domains of air traffic management, air navigation services, and airport operations.” Compliance deadline is May 1, 2025.
