PRB monitoring
▪ Luxembourg registered an average airport arrival ATFM delay of 1.36 minutes per flight in 2023, thus not achieving the local target of 0.05 minutes.
▪ Compared to 2022, the number of IFR arrivals in Luxembourg increased by 3.1%, while the average airport arrival ATFM delay increased from 0.10 to 1.36 minutes per flight.
▪ The main reason for delays was other, non-ATC related causes, accounting for 93% of delays.
The scope of RP3 monitoring for Luxembourg comprises the main airport (ELLX), where traffic in 2023 was still 6% lower than in 2019 with an increase of 3% with respect to 2022.
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 delays in 2023 was 1.36 min/arr, compared to 0.10 min/arr in 2022. The national target was not met.
ATFM slot adherence has improved (2023: 95%; 2022: 94.1%).
Arrival ATFM delays at Luxembourg have 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). 47% of all delays were attributed to equipment issues and 45% were attributed to “Other” regulation reason.
According to Luxembourg’s monitoring report:
Imposed traffic reductions by our NSA, due to a Level I finding. NMOC regulations in place from May to December due to a lack of ATSEP qualifications (12 arrivals per hour until mid-July and 16 as of mid-July until mid-December). Thanks to the reorganisation and restructuring of the CNS and the arrival and training of new ATSEPs, those restrictions have been cancelled end of the year.
As part of its oversight activities, the NSA-LU did impose a reduction on ATC Capacity due to lack of adequate staffing levels and qualified/competent ATSEPs to perform all relevant duties as required by the current regulatory requirements. The staffing levels reached an acceptable status at the end of 2023, therefore all restrictions were withdrawn.
The NSA is currently monitoring the overall situation at CNS level (especially on the NAV and SUR service provision) that might affect the overall capacity target due to implementation of ATFM restrictions.
The incentive scheme uses modulated pivot values limited CRSTMP delay causes. This pivot value for CRSTMP is 0.05 min/arr in 2023 (same as the national target all reasons). According to the attribution of the regulation reason, the actual CRSTMP value for 2023 is 0.049 min/arr, falling within the deadband. The NSA however mentions in the monitoring report that As the Luxembourg PP was only adopted in 2023 this incentive scheme is not applicable.

ATFM slot adherence
Luxembourg’s ATFM slot compliance continues improving along RP3. In 2023 it was 95%, an improvement with respect to 2022 (94.1%).
With regard to the 5% of flights that did not adhere, 2% was early and 3.1% was late.
Luxembourg’s monitoring report adds:
Slight improvement; slot adherence getting better due to monthly recap about performances.
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.
