Environment - Bulgaria

Download Report

PRB monitoring

▪ Bulgaria achieved a KEA performance of 3.52% compared to its target of 2.25% and did not contribute positively towards achieving the Union-wide target.

▪ The NSA states the reasons for not meeting the environmental targets are related to the geopolitical situation and airspace restrictions resulting from Russia’s war of aggression against Ukraine, continuous shifts in traffic flows, airspace user preferences, and a lack of sufficient capacity in neighbouring ACCs resulting in additional traffic in Sofia FIR.

▪ Both KEP and SCR remained stable in comparison to 2023.

▪ Bulgaria has no airports regulated under the performance and charging scheme.

En route performance

Horizontal flight efficiency of the actual trajectory (KEA) (KPI#1), of the last filed flight plan (KEP) (PI#1) & shortest constrained route (SCR) (PI#2)

Civil-Military dimension

Focus on Civil-Military dimension

Update on Military dimension of the plan

National legislation was updated recently to improve coordination and reduce activation/deactivation time of military areas. According FUA some reserved/restricted areas have been replaced by prior coordination area (PCA) procedure to improve capacity and efficiency. Eurocontrol CIMACT and LARA tools were implemented. The vertical and horizontal boundaries of several TRAs are reduced or changed to allow civilian traffic especially from/to the LTFM and other Istanbul airports. A reduction in the applicable separation for interoperable military aircraft is planned to improve capacity while maintaining safety levels. Letters of agreement between civilian ATS units and military controlling units. Agreement for military operations outside segregated airspace. Agreement for information exchange and for usage of CIMACT and LARA tools/systems.
