En route performance

En route ATFM delay (KPI#1)

Summary of capacity performance

Norway experienced an increase in traffic from 529k flights in 2022, with marginal delay (3k minutes), to 529k flights in 2023 with 17k minutes of en-route ATFM delay. For reference in 2019, Norway handled 595k flights with <2k minutes of en-route ATFM delays.

NSA’s assessment of capacity performance

En Route: No specific capacity issues in 2023, actual traffic in (service units) was 0,5% above the level set in the PP. The actual en-route atfm delay per flight of 0,03 min./flt. (all causes included) was significant below the national target set to 0,08 min./flt. Actual performance is so far in RP3 better than set in the rev. PP.

Monitoring process for capacity performance

No remarks.

Capacity planning

Norway has been developing ATC capacity over years, and is in position to provide more capacity than the national reference values. Based on consultation meetings with the airspace users and Avinor ANS, 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)

Not applicable.

Additional Information Related to Russia’s War of Aggression Against Ukraine

Initially there was some drop in overflights, which have recovered since. In general en route capacity has not been affected.

En route Capacity Incentive Scheme

Avinor Flysikring AS (Avinor ANS): The adopted incentive scheme does not foresee the payment of any bonus even though the capacity targets were 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.

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.

Regarding the APDF implementation and the calculation of the pre-departure delays at Bergen, Norway started providing data in October 2023, so the indicators should be available as of 2024. Traffic at the ensemble of these four Norwegian airports in 2023 was still 8% lower than in 2019.

Average arrival ATFM delays in 2023 was 0.16 min/arr, compared to 0.10 min/arr in 2022. The national target was met. ATFM slot adherence remained very high (2023: 99.2; %2022: 99.3%).

For the second year in a row, arrival ATFM delays increased at Oslo (ENGM; 2019: 0.31 min/arr; 2020: 0.05 min/arr; 2021: 0.01 min/arr; 2022: 0.17 min/arr; 2023: 0.30 min/arr) while the rest of airports registered minimum delays. 94% of the arrival ATFM delays in Norway were attributed to Weather, followed by ATC Staffing issues (6%) at Oslo.

According to the Norwegian monitoring report: The actual terminal and airport ANS ATFM arrival delay per flight of 0,16 min./flt. at a national level in 2023, significant below the national target set to 0,50 min./flt. Actual performance is so far i RP3 better than set in the PP. A significant part of the delays are reported in 2023 are connected to weather conditions i April (0,34). November (0,47) and in December (0,37).

Norway’s performance plan sets a national target on arrival ATFM delay for 2023 of 0.50 min/arr. This target was met with an actual performance of 0.16 min/arr. The incentive scheme uses modulated pivot values limited to CRSTMP delay causes. This pivot value for CRSTMP is 0.08 min/arr in 2023. According to the attribution of the regulation reason, the actual CRSTMP value for 2023 is 0.009 min/arr. The Norwegian Performance Plan does not establish any bonus.

ATFM slot adherence

All Norwegian airports showed adherence above 98% and the national average was 99.2%. With regard to the 0.8% of flights that did not adhere, 0.4% was early and 0.4% was late. According to Norway’s monitoring report: Adherence to ATFM slots at national level in 2023 (99,2%) is approx. in line with previous years both in RP3 and in RP2, I.e. excellent performance.

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 remained similar to 2022 (ENGM; 2019: 0.14 min/dep.; 2020: 0.05 min/dep.; 2021: 0.06 min/dep.; 2022: 0.10 min/dep.; 2023: 0.11 min/dep.). According to Norway’s monitoring report: Pre-departure delay in 2023 (ENGM) increasing compared to the two previous years during the pandemic, still below the level before the pandemic (2017-2019). Pre-departure delay not calculated at ENBR for 2023. In October 2023 Avinor modified the data delivery to EUROCONTROL and completed the technical configuration of DANSAP to integrate Bergen airport in the monthly reporting procedure. As of 2024, the yearly value for pre-departure delay will be reported. For the months October-December 2023, there were no ATC pre-departure delay at ENBR.

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 decreased in 2023 (ENGM: 2020: 5.01 min/dep.; 2021: 6.74 min/dep.; 2022: 12.74 min/dep.; 2023: 11.13 min/dep.) and resulted in the second lowest value among the RP3 monitored airports.

According to Norway’s monitoring report: Average time of all cause departure delay per flight in 2023 was reduced at ENGM compared to 2022 and is well below the level of delay experienced in 2019. Same as for ATC pre-departure delay, this indicator should be available for Bergen as of 2024. For the months October-December 2023, average time of all cause departure delay per IFR flight at ENBR was calculated by Avinor to 8,44.
