Capacity - Norway

Download Report

PRB monitoring

▪ Norway registered near zero minutes of average en route ATFM delay per flight during 2021, thus meeting the local breakdown value of 0.06.

▪ En route ATFM delays in Norway were also near zero on average during the past years.

▪ Traffic is expected to grow, with 2019 levels likely being reached in 2023 in high growth scenario but expected to remain below 2019 levels in base growth scenarios. A slight increase in the number of ATCOs in OPS is planned in Bodo ACC with a more significant increase in Oslo and Stavanger ACCs by the end of RP3.

▪ The share of delayed flights with delays longer than 15 minutes in Norway decreased by 17.89 p.p. compared to 2020 and was lower than 2019 values.

▪ The yearly total of sector opening hours in Bodo ACC was 22,463, showing a 15.1% decrease compared to 2020. Sector opening hours are 34.3% below 2019 levels. The yearly total of sector opening hours in Oslo ACC was 13,913, showing a 10.9% decrease compared to 2020. Sector opening hours are 49.6% below 2019 levels. The yearly total of sector opening hours in Stavanger ACC was 13,443, showing a 3.8% decrease compared to 2020. Sector opening hours are 35.7% below 2019 levels.

▪ Bodo ACC registered 7.19 IFR movements per one sector opening hour in 2021, being 19.1% above 2019 levels.

En route performance

En route ATFM delay (KPI#1)

Summary of capacity performance

Norway experienced an increase in traffic from 346k flights in 2020 to 376k flights in 2021, with zero ATFM delay. However, traffic levels were still substantially below the 595k flights in 2019.

No explanation was provided for the considerable discrepancies between actual operational ATCO FTEs reported for 2020 in the 2020 monitoring report and what has been reported for the same year in the latest annual monitoring report.

NSA’s assessment of capacity performance

The actual en-route atfm delay per flight of 0,00 min./flt. in 2021 was significant below the national target set to 0,06 min./flt. Actual performance was so far in RP3 much better than capacity target.

Monitoring process for capacity performance

Frequently at national level.

Capacity planning

Norway has been developing ATC capacity over years, and is in position to provide more capacity than the national reference values.The cost optimum capacity for en route delay per flight for Avinor ANS is between 0,18 min/flt. and 0,11 min/flt., but for the airspace users this would be unacceptable. This view is based on the fact that a large portion of the overall traffic is transition flights with little leeway in terms of delays. Based on consultation meetings with the airspace users and Avinor ANS during the en route delay is set to between 0,08 min./flt and 0,11 min./flt. in RP3.

Avinor ANS has over the last years been increasing capacity, in order to being able to shift to new technology without major operational consequences for the airspace users.

Application of Corrective Measures for Capacity (if applicable)

Other indicators

Bodo ACC: Norway has previously reported 36,7 FTE ATCOs for 2020 in ENBD ACC.
Oslo ACC: Norway has previously reported 73,1 FTE ATCOs for 2020 in ENOSE ACC.
Stavanger ACC: Norway has previously reported 25,5 FTE ATCOs for 2020 in ENOSW ACC.

Terminal performance

Arrival ATFM delay (KPI#2)

Norway has identified four airports as subject to RP2 monitoring. However, in accordance with IR (EU) 2019/317 and the traffic figures, only two of these airports (Oslo (EGNM) and Bergen (ENBR)) must be monitored for pre-departure delays. Oslo (A-CDM implemented) is the only Norwegian airport that has finished the full implementation of the Airport Operator Data Flow required for the monitoring of these pre-departure delays. As reported in RP2, it seems the ATM system is not ready to implement the APDF at Bergen. Avinor Flysikring AS, the service provider in Norway, is still considering alternate solution, but needs to take into account the additional cost required.
Traffic at the ensemble of these four Norwegian airports in 2021 was still 40% lower than in 2019.

Average arrival ATFM delays in 2021 was 0.01 min/arr, compared to 0.03 min/arr in 2020.
ATFM slot adherence has slightly improved (2021: 98.6%; 2020: 98.4%).

Arrival ATFM delays in 2021 decreased and became marginal at all Norwegian airports and disappeared at Trondheim (ENVA).
Oslo (ENGM; 2019: 0.31 min/arr; 2020: 0.05 min/arr; 2021: 0.01 min/arr) only observed marginal delays in the last two months of the year with 95% attributed to weather.
Bergen (ENBR) registered weather related delays only in January, and Stavanger (ENZV) only had 21 minutes of delay in March attributed to ATC equipment.

The provisional national target on arrival ATFM delay in 2021 was met.

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.
According to the Norwegian monitoring report: The actual terminal and airport ANS ATFM arrival delay per flight of 0,01 min./flt. in 2021 is significant below the national target set to 0,50 min./flt. Actual performance was so far in RP3 much better than the terminal capacity target

ATFM slot adherence

With the drastic drop in traffic, the share of regulated departures from Norwegian airports virtually disappeared until July 2021.
All Norwegian airports showed adherence above 93% and the national average was 98.6%, very similar to the observed performance in 2020 (98.4%). With regard to the 1.4% of flights that did not adhere, 1% was early and 0.4% was late.

ATC pre-departure delay

The calculation of the ATC pre-departure delay is based on the data provided by the airport operators through the Airport Operator Data Flow (APDF) which is properly implemented at Oslo but not implemented at Bergen. Therefore the monitoring of this indicator in Norway is limited to Oslo.
The performance at Oslo remains good and similar to the 2020 value (ENGM; 2019: 0.14 min/dep.; 2020: 0.05 min/dep.; 2021: 0.06 min/dep.)

All causes pre-departure delay

The calculation of the All causes pre-departure delay is based on the data provided by the airport operators through the Airport Operator Data Flow (APDF) which is properly implemented at Oslo but not implemented at Bergen. Therefore the monitoring of this indicator in Norway is limited to Oslo.
The total (all causes) delay in the actual off block time at Oslo increased in 2021 (ENGM: 2020: 5.01 min/dep.; 2021: 6.74 min/dep.) but still resulting in the lowest value among the RP3 monitored airports. The highest delays per flight were observed in December, averaging more than 12 min/dep.
