environment – PRB Annual Monitoring Report

Environment - Lithuania

PRB monitoring

▪ Lithuania achieved a KEA performance of 12.19% compared to its target of 1.92% and did not contribute positively towards achieving the Union-wide target.

▪ The NSA states that the KEA deterioration was due to route extensions because of Russia’s war of aggression against Ukraine. The NSA also highlights that Lithuania’s geographical location is a barrier to environmental performance.

▪ Both KEP and SCR improved in comparison with 2023. Despite the KEA target being missed, KEA improved in 2024. Additionally, the improvement in SCR shows that Lithuania has enhanced the environmental efficiency of its airspace when accounting for impacts outside of its control.

▪ Lithuania has no airports that are regulated under the performance and charging scheme.

Civil-Military dimension

Focus on Civil-Military dimension

Update on Military dimension of the plan

Impact on environmental KPA is significant due to increased MIL activities in the Baltics region (to negative side). Airspace design Stage I is completed in Q2 2025, new modular TSA were established and are in use. Stage II of new MIL areas are under consideration to support current and future MIL activities. FUA principles are applied for day-to-day airspace managemet, procedures are implemented based on LoA with ASM tool LARA in use between CIV-MIL.

Military - related measures implemented or planned to improve capacity

15 new modular TSAs were created, tested and are in operation. Dynamic mode of TSA activation is introduced to support unplanned MIL activities at tactical level (tactical activation for MIL not affecting CIVIL/GAT, is defined in LoA). New modular TSAs with more dynamic/flexible ways of management solved part of airspace capacity issues, balanced military and civil airspace needs at least for MIL exercises/daily training. INTEL/SURVEILANCE flights most propably will remain, ANSP has no authority to regulating this part of MIL operations.

Initiatives implemented or planned to improve PI#6

ON implemented the latest version of LARA (v4.0) to enhance related performance. An upgrade to LARA version 5.1 is planned for 2025. This aspect will be monitored through periodic audits conducted by the National Supervisory Authority (NSA).
