• A Functional Airspace Block (FAB) is defined in the Single European Sky (SES) legislative package, as an airspace block based on operational requirements and established regardless of State boundaries, where the provision of air navigation services and related functions is performance-driven and optimised through enhanced cooperation among air navigation service providers or, when appropriate, an integrated provider.
• NEFAB – North European Functional Airspace Block (State level agreement); Estonia, Finland, Latvia, Norway (ANSPs: EANS, Finavia, LGS, Avinor).
• NEFRA – North European Free Route Airspace (based on State level cooperation declaration); Inter-FAB programme to implement cross-border FRA between DK/SE FAB and NEFAB.
• Borealis Alliance – (ANSP alliance; Avinor, EANS, Finavia, IAA, Isavia, LFV, LGS, NATS, Naviair.
• Borealis FRA programme; to implement FRA across northern Europe, stretching from the eastern part of the North Atlantic to the western boundary of Russian airspace.

• A specified airspace within which users may freely plan a route between a defined entry point and a defined exit point, with the possibility to route via intermediate (published or unpublished) way points, without reference to the ATS route network, subject to airspace availability. Within this airspace, flights remain subject to air traffic control.
• FRA is key to the delivery of fuel efficient, cost efficient and environmentally friendly user preferred routings. FRA is one of the top priorities for airspace users within Europe and will mark a major step towards the Single European Sky (SES).
• The larger the FRA area – the larger the benefits.
• Cross-border FRA contributes to a seamless ATM environment, eliminating requirements for flight planning via mandatory boundary points.
What is FRA and why?

• If the planned trajectory takes the flight into the Free Route Airspace the flight is eligible for user preferred routing.
• In user preferred routing, the route may contain significant points, NAV aids or lat/longs and DCT between these points.
• Special conditions apply when arriving and departing to/from an aerodrome.
• The FRA relevance of the significant points are published in AIP ENR 4.1 and 4.4:
(E), for “FRA Horizontal Entry Point”
(X), for “FRA Horizontal Exit Point”
(I), for “FRA Intermediate Point”
(A), for “FRA Arrival Connecting Point”
(D), for “FRA Departure Connecting Point”
* Combinations of letters can be used for a significant point, e.g.: (EX)

FRA Horizontal entry/exit
When entering and exiting the FRA area from/to an adjacent airspace, it is mandatory to insert a FRA Horizontal Entry Point and a FRA Horizontal Exit Point. Cross border DCT between the participating FIR’s is allowed for eligible flights (no point on the FIR boundary is required).

Departing traffic is allowed to flight plan DCT from a FRA Departure Connecting Point (D) regardless of altitude at this point. A FRA Departure Connecting Point can either be;
• A SID Final Waypoint
• A specific connecting point linked to an aerodrome according to RAD, Appendix 5
• If required, the last point on a FRA Connecting Route as described in ENR 3.5
• If no suitable SID is available or there is no requirement for a connection point, a waypoint within a required distance from the aerodrome according to the RAD, Appendix 5.

Arriving traffic is allowed to flight plan DCT to a
FRA Arrival Connecting Point regardless of

Point (A) can either be;
A STAR Initial Waypoint;
A specific connecting point linked to an
aerodrome according to the RAD, Appendix 5;
If required, the first point on a FRA
Connecting Route as described in ENR 3.5;

FRA Connecting Routes
FRA Connecting Routes (ATS-routes) are established for some airports in order to segregate trafficflows/reduce complexity.

Airspace Management (ASM)
When a booking is received for an AMC Manageable Area (AMA) the airspace is blocked by IFPS. Any trajectory filed through this airspace will be rejected and a revised flight plan avoiding the area will need to be submitted.

The following systems support is deemed as basic requirements to accommodate NEFRA operations:
a) The ATM systems have to be able accept and process the NEFRA flight plans.*
b) NEFRA ACC`s shall be able to process and coordinate flights via OLDI. This coordination shall be based on the point where the planned DCT crosses the ACC boundary.
* This also means that the individual ATM-system must be capable of handling all FRA relevant points in NEFRA.
ATM-system requirements

Aircraft operators - flight planning capabilities
In order to take the full benefits of FRA AO`s need the flight planning capability, e.g.: - advanced flight planning software- access to relevant information- human flight planning resources
Filing of flight plans can be a very complex task for AO`s. There are a number of factors to take into account and some of these factors can also change at a very late stage in theprocess, e.g. airspace availability, RWY in use.
In a cross-border FRA we can still expect to see FPLs wholly or partly via ATS-routes and «strange FPL`s» due to AO`s flight planning limitations or preferences.
In a FRA environment ATC`s role should be to try to fullfill the AO`s FPL, as this is supposedto reflect their user preferred routing. Tactical DCT`s should be minimised to avoid extraworkload in upstream and downstream units.
