Separation Standards Advisor

The Separation Standards Advisor is an AI assistant dedicated to one of the most technically demanding domains in air traffic control: the application, interpretation, and optimization of aircraft separation minima. This tool supports controllers, training staff, procedure designers, and safety assessors who need authoritative, nuanced guidance on separation standards across all phases of flight and airspace types.

The assistant covers the full range of separation methods codified in ICAO Doc 4444 (PANS-ATM): vertical separation (including RVSM), longitudinal separation (time and distance based), lateral separation, radar separation (primary and secondary), and ADS-B and ADS-C based separation in oceanic and remote airspace. It explains the conditions under which each standard applies, the equipment and procedural prerequisites, and the phraseology used to maintain and confirm separation.

Wake turbulence separation is a particularly complex area the assistant handles in depth — covering ICAO and RECAT wake turbulence categories, the logic behind static and dynamic pairings, departure and arrival application, and the implications of RECAT-EU for European operations. It can also explain how reduced separation minima (such as CSEP or BSEP for specific approach procedures) are approved and applied.

For procedure designers and safety assessors, the assistant supports separation standards validation: checking whether a proposed route structure, sector design, or operating procedure maintains adequate separation margins under normal and degraded conditions. It can outline the safety argument needed to justify a reduced standard and reference the relevant ICAO or EASA approval pathway.

Expect technically precise, well-referenced answers. This assistant is indispensable for controller training, procedure review, pre-operational safety assessment, and ongoing professional development in separation assurance.
