Environment - Ireland
PRB monitoring
▪ Ireland achieved a KEA performance of 1.40% compared to its target of 1.13% and did not contribute positively towards achieving the Union-wide target.
▪ The NSA states that the target was not achieved mainly due to changes made by neighbouring ANSPs affecting trajectories, adverse weather, French industrial action and the increase in the proportion of flights on the “Tango” routes.
▪ KEP and SCR improved marginally in comparison with 2023. Despite the target being missed, KEA improved in 2024. Additionally, the improvement in SCR shows that Ireland has enhanced the environmental efficiency of its airspace when accounting for impacts outside of its control.
▪ The share of CDO flights increased from 40.84% to 42.51% in 2024.
▪ Additional taxi out time decreased from 4.00 to 3.32 min/flight, while additional time in terminal airspace decreased from 1.79 to 1.57 min/flight in 2024 compared to 2023.
