The transition to digital NOTAMs (Notices to Airmen) is essential for enhancing aeronautical information exchange globally. With the Aeronautical Information Exchange Model (AIXM), there is now a structured approach to streamline this process, enabling system-to-system data sharing. Legacy NOTAMs can be encoded digitally, ensuring improved data quality and traceability. This requires a collaborative effort among AIM engineers, policy makers, and relevant stakeholders. The path forward involves addressing industry requirements, establishing clear operational policies, and maintaining a secure chain of custody for digital NOTAMs.
E N D
Towards digital NOTAMs • International recognition that we need to move to digital information exchange • There is a global exchange model available • Aeronautical Information Exchange Model (AIXM) • Describes aeronautical information and relationships • Designed for system to system exchange of data • We now understand that existing legacy NOTAMs can be encoded digitally • Data Quality must start at the beginning of the process (survey) and must be maintained • Trace-ability of data source and modification • Chain-of-Custody
