Free Route Airspace (FRA)
NEFAB FRA is a key enabler in the NEFAB Programme for operational flexibility and benefits for the airspace users. Other elements are being implemented to support ATC and users in FRA operations, such as improved coordination between air traffic control centres and with the Network Manager enhancing capacity and maintaining safety levels. Changes in Airspace Management have been implemented involving structural changes in design of temporary segregated areas, enhancements in Flexible Use of Airspace processes to improve airspace management and predictability for civil and military users.
The shortest trajectory is not necessarily the most efficient. NEFAB FRA concept solution is based on user preferred trajectories, enabling operators to plan and operate most efficient trajectories taking all variables into consideration (distance, time, unit rates, and winds).
Free Route Airspace extension
The FRA is covering Norway (Norway FIR), Finland (Finland FIR), Estonia (Tallinn FIR/UIR), Latvia (Riga FIR/UIR), and Bodø Oceanic FIR, and is implemented as low as possible:
- FL95 – FL660 in Finland and Estonia
- FL95 – FL460 in Latvia
- FL135 – FL660 in Norway
- FL195 - FL660 in Bodø Oceanic FIR*
* Separate FRA volume where entry/exit points are required in the flight plan.
Fixed route network maintained
ATS-route network is maintained as an option for airspace users, and ensures connectivity with adjacent and subjacent fixed route network airspace.
FRA interface with Denmark and Sweden (NEFRA)
NEFAB and Danish/Swedish FAB have been cooperating to establish a seamless FRA interface between NEFAB FRA and DK/SE FAB FRA (North European FRA Programme - NEFRA). Seamless interface is enabling flight planning across the FAB and State borders without requirement to plan and cross the borders at specified points.
NEFRA is the interface between NEFAB FRA and DK/SE FAB FRA:
