Scientific paper ID 2300 : 2022/3

2022 marks the 10th anniversary of the implementation of the Agreement on the Establishment of a Functional Airspace Block DANUBE FAB between the Republic of Bulgaria and Romania. It has been concluded in accordance with the Single European Sky Regulations of the European Parliament and of the Council and the relevant implementing acts, in order to establish a functional airspace block in the airspace for which the Republic of Bulgaria and Romania are responsible. The original idea was to reduce the negative aspects of crossing many state borders by allowing the use of airspace along the most direct air corridors, while preserving the sovereignty of each of the participating countries.

The real value of the economic benefits of using DANUBE FAB is manifested after the establishment of free route airspace (FRA), which s neighboring countries of Bulgaria and Romania. To date, Hungary and Slovakia have joined the FRA initiative, and interest has been shown by Moldova and northern Macedonia, which have observer status within DANUBE FAB.

The purpose of this report is to present the development of the idea of implementing a green deal in the field of air transport, as a result of which the reduction of environmental pollution from air traffic passing through the airspace of DANUBE FAB is reported.
