The System Architecture overview contains two diagrams that display:
The European ATM System, as a set of Capability Configurations, performs operations which depend on the exchange of information with several external Capability Configurations.
The European ATM System Architecture Overview provides a set of reference Capability Configurations required to support the full set of ATM capabilities and activities defined in the SESAR Concept of Operation.
The various interactions between Capability Configurations are represented with one single line for simplification. Clicking on an element of the diagram will display more information about the capability configuration, including the resources that constitute them (in terms of technical systems, human roles) and the provided/consumed services.
