Traffic (En route traffic zone)

  • Croatia recorded 1,001K actual IFR movements in 2025, +8.6% compared to 2024 (922K).

  • Actual 2025 IFR movements were +8.7% above the plan (921K).

  • Actual 2025 IFR movements were +40.2% above the actual 2019 level (714K).


  • Croatia recorded 3,206K actual service units in 2025, +5.3% compared to 2024 (3,046K).

  • Actual 2025 service units were +6.8% above the plan (3,001K).

  • Actual 2025 service units are +46.2% above the actual 2019 level (2,193K).

Safety (Main ANSP)

  • In 2025, Croatia Control achieved the planned maturity levels set out in its performance plan for all five components of the EoSM. In more detail, Croatia Control exceeded the planned level in Safety Policy and Objectives.

  • Croatia has not included any airports in their RP4 performance plans, thus not reporting on runway incursions during the reference period.

  • The rate of separation minima infringements (SMIs) at State level was 0.29, and at ANSP level 0.29. Both indicators were below the Union-wide average. When comparing to 2024, the rate of separation minima infringements has decreased at both State level and at ANSP level.

Environment (Member State)

  • Croatia registered a KEA performance of 1.47% compared to its target of 1.46%. KEA improved from 1.56% in 2024 and the target was nearly achieved. The NSA states the main reason for not meeting the target can be mainly attributed to factors beyond the ANSPs direct influence, like airline route adjustments in response to adverse weather conditions and constraints in congested airspace.

  • Both KEP and KES improved in comparison to 2024. The improvement in KES shows that Croatia has improved the element of horizontal flight efficiency that is under its control.

  • VFE of the actual trajectory was at 74.70%, which was below the average Union-wide average.

  • No airports are included in the performance plan for monitoring.

Capacity (Member State)


  • Croatia registered 0.38 minutes of average en route ATFM delay per flight during 2025, which has been adjusted to 0.42 during the post-ops adjustment process, thus not achieving the local target value of 0.29. Delays in Croatia decreased by -1.09 minutes per flight year-on-year. Delays were highest in July and August, mostly driven by weather and ATC capacity.

  • The share of delayed flights with delays longer than 15 minutes in Croatia decreased by -9 percentage points compared to 2024, but was higher than 2019 values.

  • The number of ATCOs in OPS was 108, being below the 2025 plan in Zagreb ACC by -7 FTE.

  • The yearly total of sector opening hours in Zagreb ACC was 40,409, showing a 6% increase compared to 2024.

  • Zagreb ACC registered 23.61 IFR movements per sector opening hour in 2025, 2% above the 2024 level.

Cost-efficiency (En route/Terminal charging zone(s))


  • The en route 2025 actual unit cost of Croatia was 33.78€2022, -8.6% lower than the determined unit cost (36.96€2022). Croatia does not have a terminal charging zone.

  • The en route 2025 actual service units (3.2M) were +6.8% higher than the determined service units (3.0M).

  • The en route 2025 actual total costs were -2.6M€2022 (-2.4%) lower than determined, with all cost categories registering lower-than-planned costs, except staff costs. This is mainly due to lower other operating costs (-2.8M€2022, or -15.1%) and depreciation (-2.5M€2022, or -18.4%) for Croatia Control. The NSA explained this decrease by the deferral of investment projects which resulted in lower-than-expected expenditures, as well as lower intellectual services and travel costs. This was partially compensated by higher staff costs than planned (+3.7M€2022, or +5.8%) for Croatia Control, which the NSA attributed to an adjustment of labour expenses reflecting inflationary pressures.

  • Croatia Control costs of investments were 15.5M€2022 in 2025, -14.4% less than determined (18.0M€2022). According to the NSA, this is mainly due to delays in the entry into operation of some projects and reduced availability of ATCOs for non-operational duties.

  • The en route actual unit cost incurred by users in 2025 was 37.96€ (-7.5% below the 2025 DUC). The difference between the AUCU and the DUC is mainly driven by other revenues and the traffic risk sharing adjustment.
