Safety - Slovenia

PRB monitoring

▪ Slovenia Control has improved in Safety Risk Management in 2024 and achieved the RP3 EoSM targets in all management objectives.

▪ Slovenia recorded stable safety performance with a decrease in the rate of runway incursions and of separation minima infringements in 2024. The CAA monitors occurrence reporting through the oversight function.

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

Focus on EoSM

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

Slovenia Control started RP3 being on maturity level C on all five Management Objectives and stayed on this level, as planned, until 2024. In 2024, Slovenia Control reached maturity level D in Safety Risk Management and hence achieved the RP3 targets. The ANSP has successfully implemented a transition plan focusing on risk assessment, that was reviewed and approved by the NSA.

Safety occurrences

Rate of runway incursions (RIs) (PI#1)

Focus on runway incursions

Up until 2023, Slovenia recorded an increased rate of RIs, exceeding the Union-wide average in 2022 and 2023. Between 2023 and 2024, a significant decrease of the number of RIs was recorded, and the rate dropped below the Union-wide average.

Rate of separation minima infringements (SMIs) (PI#2)

Focus on separation minima

The rate of SMIs at the Member State level increased sharply from 2020 to 2022. Between 2022 and 2023, the rate fell marginally, with a large decrease in 2024. The rate of SMIs with ANS contribution followed the same pattern with no SMIs reported for 2024.

Quality of occurences reporting

The number of occurrences reported at Member State level seems consistent with the occurrences reported at the ANSP level for SMIs and RIs.
