In 2016 a multinational project “SEAFRA” covering cross-border application of the free route airspace concept in the airspace of 4 states on the South-East Axis (SEAFRA) was successfully implemented and completed. The night SEAFRA was implemented on 30 April 2015.
As from 8 December 2016, three ANSPs – CCL (Croatia Control Ltd), SMATSA (Serbia and Montenegro Air Traffic Services SMATSA LLC), and BHANSA (Bosnia and Herzegovina Air Navigation Services Agency) – have offered the airspace users possibility to plan and conduct flights, free of fragmentation by state or area of responsibility borders, above 9,900 m during whole day. The concept enables the use of airspace free of ATS routes, where airlines may plan their flights directly between entry and exit points of a specified airspace. H24 SEAFRA has been implemented over 4 states – Croatia, Bosnia and Herzegovina, Montenegro and Serbia.
A common goal of improving safety and efficiency in provision of ATS, and especially environment protection by possible reduction of route lengths by 1,05 mil NM, fuel consumption by 3,4 million kg, CO2 emissions by 11 million kg and NOx emissions by 40 tonnes per annum is reached.
