Safety - Croatia

PRB monitoring

▪ In 2024, Croatia Control implemented the improvements needed in Safety Risk Management to achieve the RP3 target.

▪ Croatia recorded a lower level of runway incursions (RIs) compared to 2023. The rate of separation minima infringements (SMIs) increased compared to 2023.

▪ Croatia monitored safety performance using specific safety tools, including the automated safety data recording systems for the recording of SMIs and RIs at Zagreb Airport.

Effectiveness of Safety Management (EoSM) (KPI#1)

All five EoSM components of the ANSP meet the RP3 EoSM target level. In 2024, significant improvement was observed in “Safety Risk Management” component, enabling this area to reach the target level.

Croatia Control started the reference period on the RP3 targets for three of the five Management Objectives. Safety Policy and Objectives reached the RP3 target in 2021 and improvements implemented in 2024 in Safety Risk Management ensured that all RP3 EoSM targets were achieved.

The SMS is continuously monitored through both internal and external processes, as well as through ongoing oversight by the NSA, which requires Croatia Control to provide supporting evidence of compliance. Croatia Control regularly updates its compliance matrix, which serves as the basis for demonstrating conformity with regulatory requirements.

At the start of RP3, Croatia reported a low number of RIs, which increased in 2022 with the rate exceeding the Union-wide average. In 2024, Croatia recorded a small reduction in the number of occurrences. However, given the higher number of movements, the rate of RIs fell markedly being similar to the Union-wide average.

Croatia Control has adopted the European Action Plan for the Prevention of Runway Incursions.

The SMIs followed the same evolution of the RIs. At the start of RP3, Croatia reported a low number of RIs which increased in 2022. In 2024, Croatia recorded a further increase in the number of SMIs, but with a higher number of flight hours, the rate of SMIs increased less and remained well below the Union-wide average.

Quality of occurences reporting

As reported in the Performance Plan as part of the ongoing oversight of compliance with the requirements of Regulation 376/2014 and the requirements related to SMS, the CCAA verifies whether the proposed corrective actions associated with occurrences have been implemented, whether their performance/efficiency is monitored, and whether feedback on the results is disseminated adequately. Reported occurrences are also subject to analysis by the CCAA, which is responsible at national level for receiving and analysing the occurrence reports. Alert levels are set for MAC (one of the precursors is SMI), monitored and, in case of identified deviations, mitigation measures are initiated.

Croatia Control uses automated safety data recording systems for SMI, TCAS RA, STCA and RI (only LDZA) in the purpose of risk monitoring when changes are introduced in functional systems, and for general statistical purposes.
