Modernizing national airspace architecture, PBN airway networks, terminal areas, and dynamic sectorization for CAAs and ANSPs.
Global Aviation Consultancy Services (GACS) collaborates with Civil Aviation Authorities (CAA) and Air Navigation Service Providers (ANSP) worldwide to modernize national airspace, eliminate bottlenecks, and enhance flight efficiency through optimized airspace structures and route architectures.
Utilizing proprietary airspace design tools and advanced operational paradigms such as Performance-Based Navigation (PBN), Continuous Descent Operations (CDO/OPD), and Flexible Use of Airspace (FUA), GACS designs terminal areas, airway networks, and control sectors that maximize capacity while minimizing fuel burn and environmental noise.
We assist civil aviation authorities and ANSPs across all dimensions of modern airspace architecture and operational modernization.
Re-engineering upper and lower ATS route structures to increase throughput, shorten flight tracks, and reduce CO2 emissions.
Designing seamless transition corridors, decoupled departure/arrival flows, and RNAV/RNP terminal routing.
Scientifically determining controller workload, sector boundaries, and dynamic airspace configurations.
Implementing Flexible Use of Airspace (FUA) concepts and harmonized Special Use Airspace (SUA) reservation protocols.
A data-driven engineering framework from traffic baseline modeling to operational sector commissioning.
Evaluating radar flight tracks, traffic densities, peak-hour bottlenecks, and baseline capacity constraints.
Formulating PBN route concepts, sectorization alternatives, and optimal terminal sequencing corridors.
Executing sector capacity calculations, fast-time simulation (FTS), and safety risk assessments.
Drafting Letters of Agreement (LOAs), local operating procedures (LOPs), MVA/MIA charts, and AIP updates.
Our airspace modernization packages deliver actionable operational assets:
Airspace planning conforms to ICAO Doc 9426 (Air Traffic Services Planning Manual), ICAO Doc 9613 (PBN Manual), and ICAO Doc 4444 (PANS-ATM).
Contact GACS to evaluate sector capacity, restructure terminal airspaces, and implement high-efficiency PBN route networks.
Providing specialised aviation consultancy services and software to support safe, efficient and compliant aviation development worldwide.
