En route ATFM delay
Slovenia had 588k flights in 2025, an increase from 545k flights in 2024.
Slovenia Control applied en route ATFM regulations resulting in 49k minutes of delay, an increase from the 21k minutes in 2024.
As part of the strategic traffic re-orientation programme (S25/NTDM) operated by the Network Manager, <1k minutes of delay originating in Slovenia were re-attributed to other ANSPs.
Under the auspices of the Route Network (RN) Scenarios during Capacity & Weather Based Operations between June and September 2025, <1k minutes of en route ATFM delay were re-attributed to Slovenia Control – while <1k minutes of delay originating in Slovenia, being re-attributed to other ANSPs.
When the above post-operations re-attributions are factored in, the total en route delay for Slovenia in 2025 was 49k minutes in 2025 up from 21k minutes in 2024.
Regarding the reasons and circumstances resulting in the achieved level of actual performance of the en route ATFM delay per flight KPI, the NSA reports: “Traffic much higher than planned in the Performance plan, but flexible shifts and rostering system used accomodate demand. Majority of delays is caused due to weather.”
Regarding the description of the adjustments to the capacity plan included in adopted performance plan, the NSA reports: “LARA implementation planned to be completed in 2025;
Enhanced ATFCM techniques, including STAM;
Full FRA implementation;
Additional ATCOs;
ATM system upgrades;
Flexible sector configurations, adapting regularly based on demand.”
Regarding follow up of the remedial measures indicated in the previous monitoring report(s), the NSA reports: “Additional shifts implemented, ATCOs intake and training increased.”
En route capacity incentive scheme
The Slovenian NSA reports a financial bonus for the ANSP because of the 2025 performance. The local incentive target for en route ATFM delays, due to CRSTMP causes only, was set at 0.06 mins/flight, (with a deadband of +/-0.01mins).
The NSA reports an achieved CRSTMP performance of 0.03 mins/flight but does not report how this value was verified.
The NSA reports a bonus of €225,200 for the ANSP.
