A PBN implementation for oceanic, remote continental and continental en-route operations, generally requires regional or multi-regional agreement in order that connectivity and continuity with operations in adjoining airspace can ensure maximum benefits. For terminal and approach operations, the PBN implementation is more likely to occur on a single-State basis although TMAs adjacent to national borders are likely to require multinational coordination.

Note: For instance, in the European Union the obligation to implement PBN in defined volumes of airspace is established in the framework of the Single European Sky,

Where compliance with an ICAO navigation specification is prescribed for operation in an airspace or on ATS routes, these requirements shall be indicated in the State’s aeronautical information publication.
