PRB monitoring

▪ Ireland achieved a KEA performance of 1.12% compared to its target of 1.13% and contributed positively towards achieving the Union-wide target. KEA deteriorated in comparison to 2021 but still the target was met.

▪ Both KEP and SCR deteriorated in comparison with 2021. The NSA states that they are currently reviewing the airspace and RADs with neighbouring countries.

▪ The share of CDO flights decreased by 20.77% compared to 2021.

▪ During 2022, additional time in terminal airspace increased from 0.57 to 2.02 min/flight, while additional taxi out time increased from 1.32 to 5.27 min/flight.

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)

Terminal performance

Additional taxi-out time (AXOT) (PI#3) & Arrival Sequencing and Metering Area (ASMA) time (PI#4)

AXOT

Additional taxi-out times at Dublin increased by 269% in 2022 (EIDW; 2019: 7.1 min/dep.; 2020: 2.67 min/dep.; 2021: 1.43 min/dep.; 2022: 5.27 min/dep.) resulting in the highest additional taxi-out value observed in 2022 in the SES monitored airports.

According to the Irish monitoring report: The ground infrastructure at Dublin airport is currently under redevelopment. Dublin’s new runway 28R/10L with associated taxiway structure became operational in August 2022.

ASMA

Additional ASMA times at Dublin, in the same lines as the additional taxi-out times, increased by 248% in 2022 (EIDW; 2019: 3.29 min/arr.; 2020: 1.24 min/arr. 2021: 0.58 min/arr.; 2022: 2.02 min/arr.) resulting in the highest additional ASMA value observed in 2022 in the SES monitored airports.

According to the Irish monitoring report: Dublin Airspace review is due to be completed in 2023. The ANSP and NSA meet regularly to discuss performance. The ANSP was actively involved in the PRC, ASMA and Additional Taxi Time Working Group, the ANSP is currently reviewing the revised results.

Share of arrivals applying continuous descent operations (CDOs) (PI#5)

The share of CDO flights increased at Cork (EICK) by 9.6 percentage points to 51.0% and at Shannon by 1.2 percentage points to 46.8%. Dublin had a decrease of 12.7 percentage points to 37.1%. Nevertheless, the share of CDO flights at all airports is well above the overall RP3 value in 2022 (29.0%). Dublin had a significant decrease of the monthly values as from April while the monthly values for Cork and Shannon stayed more stable throughout the year.

According to the Irish monitoring report: Low level airspace review to incorporate EICK (Cork) and EINN (Shannon) due 2023. Dublin Airspace review is due to be completed in the latter part of 2023 (CDO for Dublin operations restricted by neighbouring airspace structures).

Civil-Military dimension

Update on Military dimension of the plan

All military airspace is flight plannable and direct routes are given through activated military airspace as routine. The implementation of Point Merge at Dublin Airport was effected in a manner to ensure there was no impact on capacity at Dublin resulting from the military activity. Likewise the FRA project in 2009 also required no filing differences for military activity.

In addition the Military airspace even though proximate to Dublin Airport has no impact on the capacity of Dublin airport and this was confirmed in 2008 when differential flow rates were no longer required for military airspace activity.

Military - related measures implemented or planned to improve capacity

The NSA meets regularly with the Military through the Standing Civil Military Air Navigation Committee (StaCMAN)to discuss FUA implementation and any associated issues. Full ASM management is reliant upon the rollout of LARA. Ireland reports c.75% complete pending full LARA application. A full record of the hours of activation will be available through LARA and will be sent to NM.
