PRB monitoring
▪ AirNav Ireland met the RP3 targets in 2024, reaching maturity level D for four out of five Management Objectives during 2024.
▪ Ireland recorded a higher rate of runway incursions (RIs) and a decrease in the rate of separation minima infringements (SMIs) relative to 2023. The rate of runway incursions was above the Union-wide average.
Effectiveness of Safety Management (EoSM) (KPI#1)
All five EoSM components of the ANSP meet or exceed the RP3 target level. Over 2024, significant improvements were observed for “Safety Policy and Objectives” and “Safety Promotion” allowing achievements of the maximum maturity.
AirNav Ireland planned to meet the RP3 targets at the start of RP3, but progressed more slowly than planned in Safety Risk Management. During RP3, the maturity level for other Management Objectives decreased but remained at the target maturity level. In 2024, AirNav Ireland demonstrated an improved effectiveness in its Safety Management System, reaching maturity level D for four out of five Management Objectives, achieving the RP3 targets.
The NSA specifies that AirNav Ireland has committed substantial time, resources, and finances towards achieving Level D in all safety management categories with the exception of Safety Assurance.
AirNav Ireland monitors additional safety indicators such as airspace infringements, level bust, aircraft deviations from clearance, procedures or regulation (both on the ground and in the air).

At the start of RP3, Ireland recorded a decreased rate of RIs. However, since 2022, both the rate and the absolute number have increased, exceeding the Union-wide average in 2023 and 2024. The increase was mainly caused by a rise in occurrences without ANS contribution. The rate of RIs with ANS contribution remained low between 2020 and 2022, but increased sharply in 2023, only to decrease again between 2023 and 2024 by 50%.
The NSA has established associated safety targets and alert thresholds to provide quantifiable measures related to the achieved level of safety as defined by an acceptable level of safety performance in Ireland. Due to the increase in the rate of RIs, AirNav has implemented several organisational changes and has reviewed and updated procedures related to the level of service provided. In parallel, AirNav has reviewed the safety investigation process and overseen changes to both functional and management systems. These actions have led to safety and organisational improvements, strengthening the performance indicator.

After an increased rate of SMIs in 2021, Ireland has recorded a decrease in the rate of SMIs at Member State level. The evolution of the rate of SMIs with ANS contribution was similar to the Member State level.
Quality of occurences reporting
The number of occurrences reported at Member State level seems consistent with the occurrences reported at the ANSP level for both SMIs and RIs.
