Traffic (En route traffic zone)
▪ Slovenia recorded 545K actual IFR movements in 2024, +9.0% compared to 2023 (500K).
▪Actual 2024 IFR movements were +19.3% above the plan (457K).
▪ Actual 2024 IFR movements are +18.5% above the actual 2019 level (460K).
▪ Slovenia recorded 716K actual service units in 2024, +5.8% compared to 2023 (677K).
▪ Actual 2024 service units were +18.2% above the plan (606K).
▪ Actual 2024 service units are +14.2% above the actual 2019 level (627K).
Safety (Main ANSP)
▪ 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.
Environment (Member State)
▪ Slovenia achieved a KEA performance of 1.77% compared to its target of 1.55% and did not contribute positively towards the Union-wide target.
▪ The NSA states that the availability of the shortest flight planning option is already close to the optimum, with no delays caused by Ljubljana ACC. Therefore, the worsened environmental performance is due to airspace users’ preferences.
▪ KEP remained stable, while SCR worsened marginally compared to 2023.
▪ Slovenia has no airports that are regulated under the performance and charging scheme.
Capacity (Member State)
▪ Slovenia registered 0.05 minutes of average en route ATFM delay per flight during 2024, which remained 0.05 after the post-ops adjustment process, thus achieving the local target value of 0.09. Delays in Slovenia increased by 0.02 minutes per flight year-on-year.
▪ Delays were highest in July and August, due to adverse weather conditions.
▪ The share of delayed flights with delays longer than 15 minutes in Slovenia increased by 2 percentage points compared to 2023 and was higher than 2019 values.
▪ The average number of IFR movements was 20% above 2019 levels in Slovenia in 2024.
▪ The number of ATCOs in OPS is 67, being below the 2024 plan in Ljubljana by 5 FTEs.
▪ The yearly total of sector opening hours in Ljubljana ACC was 20,926, showing a 4.6% increase compared to 2023. Sector opening hours are 9.0% above 2019 levels.
▪ Ljubljana ACC registered 20.38 IFR movements per one sector opening hour in 2024, being 10.1% above 2019 levels.
Cost-efficiency (En route/Terminal charging zone(s))
▪ The en route 2024 actual unit cost of Slovenia was 49.44€2017, -12% lower than the determined unit cost (56.19€2017). Slovenia does not have a terminal charging zone.
▪ The en route 2024 actual service units of Slovenia (0.7M) were +18% higher than the determined service units (0.6M).
▪ The en route 2024 actual total costs were +1.3M€2017, (+3.9%) higher than determined. This difference is mainly driven by Slovenia Control’s staff costs (+1.3M€2017, or +6.1%). The NSA noted that it is mainly due to entry into force of a new collective agreement.
▪ Slovenia Control costs of investments were 3.8M€2017 in 2024, -17% lower than determined (4.6M€2017), due to “delayed investments”.
▪ The en route actual unit cost incurred by users in 2024 was 58.00€ (-4.0% lower than the 2024 DUC). This difference was mostly led by higher traffic than planned.
