Safety - Greece

PRB monitoring

▪ HASP planned to reach maturity level D for Safety Risk Management in 2024 to achieve the RP3 targets, however HASP only achieved level C.

▪ Greece recorded an increase in the rate of separation minima infringements (SMIs) and a marginally lower rate of runway incursions (RIs) in 2024 compared to 2023.

▪ In 2024, HASP implemented enhancements to its occurrence reporting and investigation processes, incorporating the Bow Tie methodology. These improvements are expected to significantly strengthen the ability to identify contributing factors and systematically develop effective risk mitigation measures aimed at preventing future occurrences.

▪ Greece should ensure that the ANSP implements, in a timely and cost-efficient manner, the necessary additional measures such as enhanced processes, improved allocation of resources, targeted training, and systematic reviews. Without such actions, the achievement of the RP4 targets could be jeopardised.

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

Focus on EoSM

Four out of five EoSM components of the ANSP meet the RP3 target level. No improvements were observed over 2024, but only “Safety Risk Management” component is below 2024 target level. Three questions are to be improved to reach the RP3 target level.

HANSP reached maturity level C for all Management Objectives as planned and aims to improve only in Safety Risk Management to achieve the RP3 targets. While some improvements have been observed, HANSP did not manage to reach maturity level D in Safety Risk Management, missing the RP3 targets.

Focus on runway incursions

Greece recorded a rate of RIs below the Union-wide average, while exceeding it in 2023. The rate decreased marginally between 2023 and 2024. The rate of RIs with ANS contribution decreased between 2023 and 2024.

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

Focus on separation minima

After a significant decrease in the number of SMIs from 2020 to 2021, the rate of SMIs has increased since then, both at Member State level and for SMIs with ANS contribution. Between 2023 and 2024, the rate of SMIs increased further, potentially because of the enhancements implemented to the occurrence reporting.

HANSP and the NSA should assess occurrences and mitigate risk according to their procedures, if necessary.

Quality of occurences reporting

The implemented enhancements to the HANSP occurrence reporting and investigation processes may have increased the number of occurrences reported in 2024 compared to 2023.
