PRB monitoring
▪ Denmark 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 0.05. Delays in Denmark decreased by 0.05 minutes per flight year-on-year.
▪ Delays were highest in June, July and September, mostly due to ATC Capacity and Staffing issues.
▪ The share of delayed flights with delays longer than 15 minutes in Denmark increased by 2 percentage points compared to 2023 and was higher than 2019 values.
▪ The average number of IFR movements was 11% below 2019 levels in Denmark in 2024.
▪ The number of ATCOs in OPS is 101, being over the 2024 plan in Copenhagen by 2 FTEs.
▪ The yearly total of sector opening hours in Copenhagen ACC was 44,464, showing a 0.3% decrease compared to 2023. Sector opening hours are 0.5% below 2019 levels.
▪ Copenhagen ACC registered 11.62 IFR movements per one sector opening hour in 2024, being 10.0% below 2019 levels.
▪ Denmark registered an average airport arrival ATFM delay of 0.50 minutes per flight in 2024, thus not achieving the local target of 0.10 minutes.
▪ Compared to 2023, average arrival ATFM delays in Denmark were 84% lower in 2024, while the number of IFR arrivals increased by 6%.
▪ The main drivers of delays were ATC staffing, accounting for 56% of delays, and weather, responsible for 33%.
Summary of capacity performance
Denmark experienced an increase in traffic from 559k flights in 2023, to 594k flights in 2024. ATFM delays reduced from 56k minutes in 2023 to 28k minutes in 2024. There were still fewer flights than in 2019 (669k).
NSA’s assessment of capacity performance
Traffic in Danish Airspace is still affected by the clossure of Russian Airspace leading to rerouting of international flights. In 2024, the en-route ATFM delay target was met.
Although recruitment efforts are ongoing, challenges remain. Naviair has implemented remedial actions, including training and ATCO recruitment, but the NSA notes that associated risks to capacity and service delivery persist. Additionally, increased traffic flows in western sectors and new segregated military airspaces are being monitored for impact.
Monitoring process for capacity performance
Monitoring process are in place and coordinated with the NM.
Capacity planning
Monitoring process are in place and coordinated with the NM.
Application of Corrective Measures for Capacity (if applicable)
NSA is in dialogue with the ANSP to ensure the best possible capacity in the years ahead. In 2025 new reserved/segregated airspaces have been implemented for Military training activities which might affect the capacity. The effect is being monitored.
En route Capacity Incentive Scheme
NAVIAIR: The NSA reports that the ANSP performance falls within the deadband range and therefore neither bonus nor malus is applicable.
In accordance with Article 3(3)(a) of Implementing Regulation (EU) 2020/1627: The incentive scheme shall cover only the calendar years 2022 to 2024.
Denmark only has Copenhagen/Kastrup (EKCH) airport subject to RP3 monitoring for which the APDF is successfully established and the monitoring of the capacity indicators can be performed. Traffic at this airport in 2024 was still 9% lower than in 2019, but 6% higher than in 2023.
Average arrival ATFM delay in 2024 was 0.5 min/arr, a drastic reduction with respect to 2023 when delays were extremely high due to lack of ATCO resources. Regardless of this reduction, the national target was not met and there are still capacity issues due to staffing shortage. ATFM slot adherence remained very high (2023: 98.8%; 2024: 99.3%).
Copenhagen had registered until 2023 nearly zero delays, but in 2023 observed significant arrival ATFM delays due to ATC staffing issues. Performance in 2024 has improved but some of the delays persist (EKCH; 2019: 0.07 min/arr.; 2020: 0 min/arr; 2021: 0.02 min/arr.; 2022: 0.02 min/arr.; 2023: 3.09 min/arr.; 2024: 0.5 min/arr.). 56% of the delays in 2024 were attributed to ATC Staffing, followed by 33% of Weather.
According to the Danish monitoring report: There were still capacity issues due to staffing shortage. The NSA is aware that recruitment and training are ongoing, with associated risks related to staffing levels and service delivery.
The Danish performance plan sets a national target on arrival ATFM delay for all RP3 of 0.1 min/arr. This target was not met in 2024 with an actual performance of 0.5 min/arr.
According to the Danish monitoring report, this performance corresponds to the maximum penalty (0.50%), automatically computed as DKK 930497.9398.

ATFM slot adherence
Copenhagen’s ATFM slot compliance in 2024 was 99.3%, showing a consistent good performance. With regard to the 0.7% of flights that did not adhere, 0.6% were early and 0.1% were late.
According to the Danish monitoring report: Performance is stable. NSA monitors the performance via monthly reports from the ANSP, and yearly evaluation.
ATC pre-departure delay
ATC pre-departure delay at Copenhagen (EKCH: 2021: 0.13 min/dep; 2022: 0.04 min/dep; 2023: 0.62 min/dep; 2024: 0.10 min/dep) decreased significantly in 2024 and got closer to the pre-pandemic value (0.09 min/dep)
All causes pre-departure delay
Influenced by the trend and underlying causes observed above, the total (all causes) delay in the actual off block time at Copenhagen decreased in 2024 (EKCH: 2020: 6.79 min/dep.; 2021: 9.63 min/dep.; 2022: 14.9 min/dep.; 2023: 15.79 min/dep.; 2024: 11.52 min/dep.)
