PRB monitoring
▪ Luxembourg registered an average airport arrival ATFM delay of 0.55 minutes per flight in 2024, thus not achieving the local target of 0.05 minutes.
▪ Compared to 2023, average arrival ATFM delays in Luxembourg were 59% lower in 2024, while the number of IFR arrivals remained the same.
▪ The main drivers of delays were ATC disruptions, accounting for 51% of delays, ATC staffing and Weather, responsible for 17-17%.
The scope of RP3 monitoring for Luxembourg comprises the main airport (ELLX), where traffic figures in 2024 were the same as in 2023 and still 6% lower than in 2019. In accordance with IR (EU) 2019/317 and the traffic volume, pre-departure delays are not monitored at Luxembourg and the capacity performance monitoring focuses on arrival ATFM delay and slot adherence.
Average arrival ATFM delay in 2024 was 0.55 min/arr, compared to 1.36 min/arr in 2023. The national target was not met. ATFM slot adherence improved (2023: 95%; 2024: 97.2%).
Arrival ATFM delays at Luxembourg had significantly increased in 2023 (ELLX: 2020: 0.06 min/arr; 2021: 0.14 min/arr; 2022: 0.10 min/arr; 2023: 1.36 min/arr; 2024: 0.55 min/arr). Regardless of an important decrease in 2024, they are still above the target. 51% of all delays were attributed to equipment issues followed by 17% to weather reasons and also 17% to ATC staffing.
According to Luxembourg’s monitoring report: PP values were not realistically defined in advance of RP3 as ANA was not familiar with ATFM delay handling. In 2023 and 2024 unexpected delays due to imposed regulations by our regulator and due to technical ILS issues
degraded the situation.
Identification and analysis by the NSA of the underlying reasons or circumstances having led to the performance target not being achieved.* A positive (improvement) trend is acknowledge with a better management of the overall capacity at ANSP level. It should be highlighted that the topic has been discussed in a recent audit related to ATFM. Some further improvements are expected in 2025.The NSA also recognizes that, during 2024, the ANSP faced some problems related to the ILS which had a significant impact on the overall capacity of the airport. The situation is now solved and capacity levels should return to normal. The monitoring performed so far by the NSA shows a positive trend in 2025.
Recommendations to the ANSP to rectify the situation Ensure that the new procedure for handling capacity adjustments are well implemented with proven results in order to achieve Capacity targets.
What action has the NSA taken to check/monitor the implementation of those measures and what further actions (if any) are planned during the ongoing calendar year?
ANA consultation process with FMP Brussels to reorganise regulations. Capacity adaption instead of regulations to avoid unnecessary delays outside peak traffic hours. Result is a significant reduction in delays. All the issues identified in past for underperformance should be solved by now.*
The incentive scheme uses modulated pivot values limited CRSTMP delay causes. This pivot value for CRSTMP is 0.04 min/arr in 2024. According to the attribution of the regulation reason, the actual CRSTMP value for 2024 is 0.379 min/arr.The NSA calculates a maximum penalty (0.25%) of EUR39522.1575.

ATFM slot adherence
Luxembourg’s ATFM slot compliance continues improving along RP3. In 2024 it was 97.2%, an improvement with respect to 2023 (95%).
With regard to the 2.8% of flights that did not adhere, 1.3% were early and 1.5% were late.
ATC pre-departure delay
This indicator is not monitored for airports below 80 000 IFR movements annual average during the 2016-2018 period, so it is not monitored for any airport in Luxembourg.
