Summary of capacity performance
Slovakia experienced an increase in traffic from 530k flights in 2023 with 17k minutes of en route ATFM delay, to 601k flights in 2024 with 67k minutes of en route ATFM delay. In 2019, Slovakia handled 562k flights with 40k minutes of ATFM delay.
There were an additional 10k minutes of delay originating in Slovakia that were re-attributed to DFS (9k) and HungaroControl (<1k) via the NM post operations delay attribution process, according to the NMB agreement for eNM/S24 measures, to ameliorate capacity shortfalls in Karlsruhe UAC and Budapest ACC.
NSA’s assessment of capacity performance
In 2024 traffic volume in terms of IFR movements actual volume exceeded number of IFR movements included in the revised performance plan by 13%. Operational situation in Slovak airspace also continued to be impacted by the war in Ukraine.
Target was not met. The average delay per flight was 0.21 minutes per flight in Summer 2024. Despite the increased traffic (24%), there was a minor deviation from target 0,04 per flight. Based on increased traffic ANSP started modification of the Bratislava CTA.
Monitoring process for capacity performance
Analysis on strategical, pretactical and post ops level is being done on regular basis using Eurocontrol’s 6 weeks
traffic forecast, NMIR Tool, Eurocontrol’s ACC Dashboard and our internal rostering tool to monitor and ensure that provided capacity meets traffic demand.
Capacity planning
The average delay per flight was 0.21 minutes per flight in Summer 2024. 58 % of the Summer delays were due to the reason ATC Capacity, 36 % due to Weather and 6 % due to Airspace Management.
Application of Corrective Measures for Capacity (if applicable)
Some of the delays were due to weather (36%) and some were due to a significant increase in traffic. The initial forecast for 2024 was 486,000 flights versus the actual 601,044 flights, representing a 24% increase in traffic.
The ANSP is implemnting the following measure to remedy the situation: CTA Bratislava modification - the modification of the Bratislava CTA is related to the introduction of sector configurations with horizontal division - will be implemented in 2026.
En route Capacity Incentive Scheme
LPS SR: Slovakia uses an incentive scheme based only on delays attributed to C,R,S,T,M & P delay codes. The CRSTMP target was set at 0.03 minutes per flight and the actual performance is reported as 0.07 minutes per flight (CRSTMP only), leading to a financial penalty for the ANSP of €564 549.
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.
