SEAFRA offers first 4-nation night free routeing

1Three central European providers – SMATSA, Croatia Control and BHANSA – are now offering night-time free route flights over the airspace of four nations.
Flights through Serbia, Montenegro, Croatia and Bosnia and Herzegovina have been able to plan cross-border Free Route Airspace (FRA) flights above FL325 since the end of April through the South-East Axis Free Route Airspace (SEAFRA) initiative.
The air navigation services providers said they are satisfied with the results of the first European FRA concept implemented over the territories of four states, two of which are members of FAB CE (Croatia and Bosnia and Herzegovina) and with Serbia and Montenegro which are not a part of any FAB initiative, proving that such cooperation is possible, and can be of benefit to all stakeholders.
“The idea of such large-scale FRA was initiated by ATM experts of the ANSPs responsible for ANS provision in different states with a common goal to improve ATS safety and efficiency on one, and the environmental protection by reducing fuel, CO2 and fuel NOx emissions on the other hand,” said the partners who added that the SEAFRA actions were taken  seven  years prior to the date planned for the unlimited free use of airspace over 9000m across Europe – 1 January 2022.
“Being carefully planned and managed, and bearing in mind that all of the providers have different ATM systems in place, the SEAFRA project initiated the implementation of the cross-border FRA concept during night hours when the traffic is lower (23.00-05.00 UTC winter time and 22.00-04.00 UTC summer time),” SEAFRA said.
This project is one of the key improvements within the EU initiative on establishing the Single European Sky regardless of state or even FAB borders, aiming to enhance safety and efficiency, and to increase capacity of air traffic in Europe.
