Case study for DANUBE FAB VCS project

DANUBE FAB finalized the replacement of the voice communication systems (VCS) in use at BULATSA and ROMATSA with two separate deployments of VCS3020X from Frequentis. The world’s first VCS to support dynamic sectorisation – VCS3020X, is a resilient, high-performance voice over IP (VoIP) platform that will enable BULATSA and ROMATSA to enhance the connectivity between their VCS networks with dynamic delay compensation for IP networks and echo-free voice experience for controllers.

DANUBE FAB @ World ATM Congress - Interactive workshop on Women in ATM

DANUBE FAB is hosting an interactive workshop on Women in ATM: A common approach to equal opportunities at the World ATM Congress in Madrid 2020. Succeeding the constructive debates on Diversity & Inclusion: From policy to practice at the “Europe for Aviation” stand at the World ATM Congress 2019, DANUBE FAB is keen to undertake the challenge of exploring avenues towards maximizing the potential of women in the European ATM.

DANUBE FAB position paper on the WPG Report recommendations

DANUBE FAB discussed on the proposed Study regarding the evolution of the European airspace architecture as well on the recommendations of the Wise Persons Group in their Report on the Future of the Single European Sky. As a result, the DANUBE FAB Governing Council members decided to issue a position paper on the Report's recommendations and to propose, amongst others, that FABs can effectively contribute to the application of a total system approach to European aviation, supported by well-defined objectives, realistic expectations and pragmatic timelines ensuring commitment and involvement of all players.

SEE FRA project successfully completed on 7th November 2019

Starting from 7th of November 2019 the Aircraft Operators will be able to plan their flights freely across the airspace of Bulgaria, Hungary and Romania 24/7 without the limitations of the geographical boundaries. This is the completion of the SEE FRA project (South East Europe Free Route Airspace) for implementing 24/7 cross border free route operations across the airspace of the 3 states. The new flight planning rules significantly optimize the flight trajectories not only by using the shortest connections but also allowing the use of the most effective routings when the impacts on the flights are inevitable e.g adverse weather avoidance.

Fourteenth meetings of the DANUBE FAB governing bodies

On the 6th and 7th of November, the members of the DANUBE FAB Governing Bodies, respectively, the Governing Council, NSA Board and ANSP Board met in Sofia for the fourteenth time since the DANUBE FAB establishment in 2012. With a very dense agenda, ranging from technical matters to more high-level political aspects the governing bodies members were briefed on of the progress of the latest round of DANUBE FAB strategic planning and reporting, status of the FAB procurements, Inter-FAB coordination activities and the progress of the FAB High Priority projects.

High Priority Projects


The establishment of DANUBE FAB is an essential element of the Single European Sky (SES) legislative framework, which creates a system of measures for provision of sufficient capacity for servicing the increasing number of flights over Europe, decreasing the delays, improving the safety and cost-efficiency of the air navigation services.


Our vision is to provide the safest, most secure, efficient and environmentally friendly air-navigation services in south-eastern Europe”. DANUBE FAB strives towards a qualitative transformation of the functional air navigation systems achieving the highest safety standards, providing the highest performing infrastructure for all users in line with a seamless single sky while ensuring effective environmental sustainability.


The objective of the DANUBE FAB, in the airspace under the responsibility of Romania and the Republic of Bulgaria, is to improve capacity, cost-efficiency of the air navigation services and environmental protection by optimising provision of ANS and civil-military cooperation in a process of sustainable development, while increasing the level of safety.
