Traffic (En route traffic zone)
▪ Slovenia recorded 500K actual IFR movements in 2023, +10% compared to 2022 (453K).
▪ Actual 2023 IFR movements were +16% above the plan (432K).
▪ Actual 2023 IFR movements were +9% above the actual 2019 level (460K).
▪ Slovenia recorded 677K actual en route service units in 2023, +14% compared to 2022 (595K).
▪ Actual 2023 service units were +19% above the plan (571K).
▪ Actual 2023 service units were +8% above the actual 2019 level (627K).
Safety (Main ANSP)
▪ Slovenia Control has already achieved the RP3 EoSM targets in four out of five management objectives in 2020 but needs to make improvements in the safety risk management objective in line with its planned maturity levels.
▪ Slovenia Control, together with the NSA, implemented multiple review processes and continuous monitoring to ensure the maintenance of high safety performance.
▪ Slovenia recorded an increase of runway incursions relative to 2022 and the same level of separation minima infringements as in previous year. Slovenia established a State Plan for Aviation Safety (SPAS 2022-2026) including both leading and lagging indicators, monitoring of precursors events which may lead to occurrences and gap analysis against European Action Plan for Prevention of Runway Incursions.
▪ Slovenia Control do not use automated safety data recording systems.
Environment (Member State)
▪ Slovenia achieved a KEA performance of 1.73% compared to its target of 1.55% and did not contribute positively towards the Union-wide target.
▪ SCR and KEP worsened compared to 2022.
▪ 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.
▪ Slovenia has no airports that are regulated under the performance and charging scheme.
Capacity (Member State)
▪ Slovenia registered 0.03 minutes of average en route ATFM delay per flight during 2023, thus achieving the local target value of 0.09. Flight delays in Slovenia increased by 0.03 minutes per flight year-on-year.
▪ Most of the delays accumulated between May and August, mainly due to adverse weather conditions and ATC system failure.
▪ The share of delayed flights with delays longer than 15 minutes in Slovenia decreased by 5 p.p. compared to 2022 and was lower than 2019 values.
▪ The average number of IFR movements was 10% above 2019 levels in Slovenia in 2023.
▪ The number of ATCOs in OPS is expected to increase by 9% by 2024, with the actual value being below the 2023 plan in Ljubljana by 1 FTEs.
▪ The yearly total of sector opening hours in Ljubljana ACC was 20,009, showing a 7% increase compared to 2022. Sector opening hours are 4.2% above 2019 levels.
▪ Ljubljana ACC registered 19.63 IFR movements per one sector opening hour in 2023, being 6.0% above 2019 levels.
Cost-efficiency (En route/Terminal charging zone(s))
▪ The en route 2023 actual unit cost of Slovenia was 50.36 €2017, -16% lower than the determined unit cost (59.84 €2017). Slovenia does not have a terminal charging zone.
▪ The en route 2023 actual service units (0.7M) were +19% higher than the determined service units (0.6M).
▪ The en route 2023 actual total costs were -52 K€2017 (-0.2%) lower than determined. This gap is attributed to the underspend in depreciation costs (-0.6 M€2017, or -18%) and in other operating costs (-0.1 M€2017, or -2.3%). According to the NSA, the difference in depreciation resulted from postponed investments, while the gap in other operating costs was due to the nominal overspend (+8.2%) being less than the overspend of the inflation index (+15%).
▪ Slovenia Control spent 3.9 M€2017 in 2023 related to costs of investments, -19% less than determined (4.7 M€2017), due to delayed investments.
▪ The en route actual unit cost incurred by users in 2023 was 60.73€ (-4.3% below the 2023 DUC).
