TECHNOLOGY DOMAIN

COLLABORATIVE NETWORKPLANNING

Integrated with airport operations planning

and airspace user flight planning

The 4D Trajectory Principle:

Integrating airspace users flight systems to

build predictable time synchronised flight

precision

Integration of Airports:

Integrating airports - time synchronised

operations of surface trajectories and flight

turnaround

System Wide Information Management:

The Intranet for Air Traffic Management

Automation:
