S-AF3.1 — Airspace Management and Advanced Flexible Use of Airspace
Airspace Management (ASM) and Advanced Flexible Use of Airspace (A-FUA) aims to provide the possibility to manage airspace reservations more flexibly in response to airspace user requirements. Changes in airspace status shall be shared with all concerned users, in particular Network Manager, air navigation service providers and airspace users (Flight Operations Centre/Wing Operations Centre (FOC/WOC)). ASM procedures and processes shall cope with an environment where airspace is managed dynamically with no fixed-route network.
Data-sharing shall be enhanced by the availability of airspace structures in support of a more dynamic ASM and Free Routing Airspace (FRA) implementation. FRA is the airspace defined laterally and vertically, allowing free routing with a set of entry/exit features. Within this airspace, flights remain subject to air traffic control.
ASM solutions shall support all airspace users, including enabling the alignment of FRA, Conditional Route (CDR) and published Direct Routing (DCT). These ASM solutions shall be based on forecast demand received from the local Air Traffic Flow and Capacity Management (ATFCM) function and/or the Network Manager.
- 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; Enhancements to the Network Operations Plan (NOP) shall be achieved through a cooperative decision-making process between all involved operational stakeholders; 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 to comply with Regulation (EC) No 552/2004, point 4 of Part A of Annex II.
- 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 AF 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
Flexible Airspace Management and Free Route shall be provided and operated in the airspace for which the Member States are responsible at and above flight level 310 in the ICAO EUR region.
