EASA (European Union Aviation Safety Agency)

EASA sets and oversees common aviation rules for the European Union, providing a single regulatory framework in place of differing national regimes. Its work spans the certification of aircraft and aviation products, the approval and oversight of organisations, standardisation of how member states apply the rules, and the issuing of airworthiness directives and safety information. Although its core mandate is safety, several of its activities bear directly on security-relevant risk.

Among the outputs most relevant to operational risk are EASA's Conflict Zone Information Bulletins, which consolidate threat assessments about specific airspace, and its Safety Information Bulletins on issues such as GNSS interference. These give operators a shared European reference that complements national advisories. EASA also coordinates with ICAO and other authorities so that European rules align with international standards.

EASA bulletins and advisories are among the authoritative sources that define airspace and navigation risk for operators in the European context. AeroVigil aggregates such official advisories and relates them to the regions and routes they affect.
