4D軌道ベース運用(TBO)による空域収容容量300%拡大の工学的実現

Technical analysis and engineering reference.

1. The Ceiling of Human Controller Sector Capacity

For decades, airspace capacity has been fundamentally constrained by human controller mental workload limits—typically capped at 15 to 20 aircraft per sector simultaneously. Controllers manually scan flight progress strips, issue voice vector commands over VHF radio, and enforce conservative buffer distances (5 nautical miles horizontally, 1,000 feet vertically).

2. Shift to Negotiated 4D Spatial Contracts

AirspaceFlow transforms air traffic from reactive vectoring into predictive contract execution: - Airlines downlink complete flight intent profiles directly from Flight Management Systems (FMS) via ADS-C. - Ground solvers evaluate the composite network across all participating flights 4 hours ahead of departure. - Dynamic speed adjustments across cruise altitudes replace fuel-wasteful holding patterns over destination airports.

3. Automated Separation Monitoring

Continuous satellite tracking and automatic ground conformance monitors verify that aircraft adhere strictly to negotiated 4D tubes. If an aircraft drifts beyond its spatial envelope, automated resolution alerts prompt instant autopilot corrections.
