Division System requirements

The ASM support system shall support the fixed and conditional route networks currently in place, as well as DCTs, FRA and flexible sector configurations; The system shall be able to respond to changing demands for airspace; F1... The system shall support cross-border activities, resulting in shared use of segregated airspace regardless of national boundaries

Airspace configurations shall be accessible via Network Manager systems, which shall contain the up-to-date and foreseen airspace configurations, to allow airspace users to file and modify their flight plans based on timely and accurate information

The ATC system shall support flexible configuration of sectors so that their dimensions and operating hours can be optimised according to the demands of the NOP

The system shall allow a continuous assessment of the impact of changing airspace configurations on the network

ATC systems shall correctly depict the activation and de-activation of configurable airspace reservations and the change of a volume of airspace from a fixed route network to FRA

The Flight Plan Processing System (IFPS) shall be modified to reflect the changes in the definition of airspace and routes so that the routes, flight-progress and associated information are available to ATC systems

The ASM, ATFCM and ATC systems shall securely interface in a way that allows the provision of air navigation services based on a common understanding of the airspace and traffic environment. The ATC systems shall be modified to enable this functionality to the extent necessary F2for effective airspace and air traffic flow management, and the safe and efficient use of airspace by all users, through the application of the concept of flexible use of airspace; whilst taking into account national security considerations.

Centralised Aeronautical Information Services (AIS) systems, such as the European AIS Database (EAD), shall make available environment data for flexible airspace structures to all involved operational stakeholders in a timely manner. This enables planning to be undertaken based on accurate information relevant to the time of the planned operations; Local AIS systems shall enable this capability and the upload of changing local data

Operational stakeholders shall be able to interface with the NOP as specified in Point 4; Interfaces shall be defined to allow dynamic data to be sent to operational stakeholder systems, and for those stakeholders to be able to communicate information in an accurate and timely manner; The systems of these stakeholders shall be modified to enable these interfaces
