Environment - Estonia
PRB monitoring
▪ Estonia achieved a KEA performance of 6.55% compared to its target of 1.22% and did not contribute positively to achieving the Union-wide target.
▪ The NSA states that the target was not achieved because of the traffic to and from Kaliningrad which does not follow the optimal routes due to the restrictive measures following Russia’s war of aggression against Ukraine.
▪ Both KEP and SCR deteriorated in comparison to 2022. The value of these two indicators is similar, meaning airspace users plan close to the shortest route available.
▪ The share of CDO flights decreased from 66.29% to 65.15% in 2023.
▪ During 2023, additional time in terminal airspace increased from 0.19 to 0.23 min/flight, while additional taxi out time decreased from 1.39 to 1.01 min/flight.
