The PBN concept has expanded area navigation techniques, originally centred upon lateral navigation accuracy only, to a more extensive statement of required performance related to accuracy, integrity and continuity along with how this performance is to be achieved in terms of aircraft equipage and crew requirements.
In Europe, PBN implementation is covered by the Commission Implementing Regulation (EU) 2018/1048 of 18 July 2018. As State aircraft operating as General Air Traffic (GAT) might not be fully compliant with the mandated PBN requirements, there is a need to ensure accommodation of those State aircraft that need to perform the sovereignty roles, which includes national security and defence missions that require unrestricted access to, and freedom within, the airspace.
The introduction and regulation of PBN implementation in Europe offers transition measures that shall apply until 06 June 2030 to accommodate non-PBN aircraft. Civil-military coordination is crucial when such national transition plans are delineated. Contingency measures will remain in place when GNSS or «other methods used for PBN» are not available. This is the case before and after 2030 but only in exceptional circumstances with a network of conventional navaids retained.
The present document offers non-binding civil-military technical guidance supporting Air Traffic Management (ATM) planners and infrastructure managers when planning and implementing PBN in Europe. Such guidance is deemed necessary to ensure the continuation of State aircraft operations performed in an efficient and unconstrained way. The document also comprises detailed information on technical requirements applicable to avionics, proposing measures for compliance that minimise cost and procurement impact.
