PRB monitoring
▪ Belgium achieved a KEA performance of 3.55% compared to its target of 3.10% and did not contribute positively to the Union-wide target. KEA performance deteriorated by 0.18 p.p. in comparison to 2020.
▪ Traffic levels fluctuated in 2021, with a sharp increase in May/June, which had an impact on KEA performance. However, higher traffic levels were managed with similar KEA performance throughout 2017-2019.
▪ Both KEP and SCR slightly deteriorated in comparison to 2020.
▪ The share of flights operating CDO in 2021 remained similar to 2020 levels.
▪ The additional time airspace users spent in terminal airspace improved by 47% in comparison to 2019. Additional taxi time slightly improved as well.
AXOT
Additional taxi-out times at Brussels decreased once more even if just slightly in 2021 (EBBR; 2019: 2.21 min/dep.; 2020: 1.36 min/dep.; 2021: 1.28 min/dep)
The reduction is in fact only due to the improvement in the firtst trimester compared to the first trimester of 2020. For the rest of the year the additional taxi-out times averaged 1.25 min/dep, almost 30 seconds more than in 2020, but still a minute lower than in 2019.
According to FABEC monitoring report: For Belgium, it is noted that some factors included in the Taxi-out time (for example: push-back time) influence this indicator but are beyond control of ANSP. A-CDM is implemented for many years, and continuously being improved. Latest improvements focused on incorporating de-icing (and hence reducing taxi times).
ASMA
Additional ASMA times at Brussels significantly decreased again in 2021 (EBBR; 2019: 1 min/arr.; 2020: 0.89 min/arr.); 2021: 0.47 min/arr.
Like with the additional taxi-out times, the annual reduction is in fact only due to the improvement in the firtst trimester compared to the first trimester of 2020. For the rest of the year the additional ASMA times averaged 0.71 min/arr., 0.21 min/dep. but still half of the additional ASMA times in 2019.
According to FABEC monitoring report: For Belgium, ASMA is considered to be intended primarily to capture terminal holdings. Within EBBR, stacking aircraft in holding to absorb delays (similar to EGLL) is seldom applied. Within a radius of 30 NM around EBBR, radar vectoring is most often applied. Depending on the traffic demand, shorter or longer trajectories are being flown (-> sequencing). However radar vectoring has the advantage that shortest routes can be issued, hence leading to ‘best possible’ ASMA values, while of course taking into account applicable restrictions (e.g. noise abatement).
Share of arrivals applying continuous descent operations (CDOs) (PI#5)
The share of CDO flights for Brussels is 19.6% which is an increase of 1.1 percentage points but still quite low compared to other airports with similar traffic numbers and the overall RP3 value (30.5%).
According to the FABEC monitoring report: For Belgium, the following (non-exhaustive) list of initiatives applies:
- CEM EBBR -> collaboration between operational stakeholders. Various initiatives are on-going to improve predictability in the arrival process, which facilitates airspace users in optimizing their descent. Example: Trials regarding ‘Increased Use RNP Approaches’ are planned for 2022. As these procedures aim to improve predictability throughout the arrival process, those allow aircraft operators to better optimize their descent.
- The Environmental Action Plan that has been developed by skeyes, where improving (vertical) flight efficiency is one of the key pillars
- A PBN Transition Plan improved and optimised PBN routes . This ameliorated predictability and consequently improved CDO performance.
