PRB monitoring
▪ Ireland achieved a KEA performance of 1.01% compared to its target of 1.13% and contributed positively towards achieving the Union-wide target. KEA is at the best levels seen in the last five years.
▪ Both KEP and SCR continued to improve, and the values are at their lowest levels in five years.
▪ The share of CDO flights increased by three p.p..
▪ Additional time in terminal airspace more than halved from 1.19 min/flight to 0.57 min/flight and additional taxi out time reduced from 2.37 min/flight to 1.32 min/flight in 2021.
AXOT
Additional taxi-out times at Dublin significantly lowered for the second year in a row (EIDW; 2019: 7.1 min/dep.; 2020: 2.67 min/dep.; 2021: 1.43 min/dep.). The additional times in the first half of the year averaged 0.18 min/dep., while the second half of the year observed a progressive increase in line with the traffic recovery, and averaging 1.81 min/dep.
According to the Irish monitoring report: Most of the factors influencing additional taxi-out time are related to aerodrome infrastructure rather than ATM capacity. For example, congestion at the runway in use adds significantly to this indicator.
ASMA
Additional ASMA times at Dublin, like the additional taxi-out times, further and significantly decreased in 2021 (EIDW; 2019: 3.29 min/arr.; 2020: 1.24 min/arr. 2021: 0.58 min/arr.). Between April and July the additional ASMA times were practically zero, and they only exceeded the minute per arrival in December (1.38 min/arr.).
According to the Irish monitoring report: The additional time is terminal airspace is generally attributable to the flights following the “Point Merge” legs in part or in full. However the Point Merge has been demonstrated to have considerable benefits to the Airspace Users in reduced fuel consumption and to the environment in lowering Co2 emissions around terminal areas, and maximising runway throughput compared to vertical holding. These benefits outweigh any impact on ASMA Time.
Share of arrivals applying continuous descent operations (CDOs) (PI#5)
The share of CDO flights increased at Dublin and Shannon by respectively 3.8 and 3.1 percentage points. Cork had a decrease of 10.6 percentage points. Nevertheless, the share of CDO flights at all airports is well above the overall RP3 value in 2021 (30.5%). Cork and Shannon had an increase of the monthly values as from June while the monthly values for Dublin stayed relatively stable throughout the year.
According to the Irish monitoring report: Low level airspace review to incorporate EICK (Cork) and EINN (Shannon) due 2022. Dublin Airspace review due later part of 2022 (CDO for Dublin operations restricted by neighbouring airspace structures). On continuous descent operations (CDO), from January to December 2021 the amount of time flown level during descents into Irish airports averaged 64.1 seconds per descent, 90.3 seconds lower than in 2019, in context the average for the top European airports in 2021 was 127.3 seconds.

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 FAB 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 activiation will be availble through LARA and will be sent to NM.
