PRB monitoring
▪ Norway registered 0.01 minutes of average en route ATFM delay per flight during 2022, thus achieving the local target value of 0.08.
▪ The average number of IFR movements was 11% below 2019 levels in Norway in 2022.
▪ An increase in the number of ATCOs in OPS is expected by the end of RP3 in Bodo ACC, with a more significant increase in Oslo and Stavanger ACCs. The actual value in Stavanger ACC was in line with the 2022 plan; while in Bodo and Oslo ACCs the actual values remain below the 2022 plan.
▪ Delays were highest in January, November and December, mostly due to ATC Capacity issues and ATC Disruptions.
▪ The share of delayed flights with delays longer than 15 minutes in Norway decreased by 10.86 p.p. compared to 2021 and was lower than 2019 values.
▪ The yearly total of sector opening hours in Oslo ACC was 15,689 in 2022, showing a 9.3% increase compared to 2021. Sector opening hours are 10.4% below 2019 levels.
▪ Oslo ACC registered 13.36 IFR movements per one sector opening hour in 2022, being 4.7% below 2019 levels.
▪ Norway registered an average airport arrival ATFM delay of 0.1 minutes per flight in 2022, achieving the local target of 0.5 minutes.
▪ Compared to 2021, average arrival ATFM delays in Norway were 914.57% higher in 2022, while the number of IFR arrivals increased by 48.84%.
▪ The main reasons for delays were weather, accounting for 51% of delays, and ATC staffing issues, responsible for 39%.
Summary of capacity performance
Norway experienced an increase in traffic from 376k flights in 2021, with zero ATFM delay, to 529k flights in 2022 - with marginal delay (3k minutes).
Traffic levels were still below the 595k flights in 2019.
NSA’s assessment of capacity performance
No specific capacity issues in 2022, actual traffic in (service units) was 1,1% above the level set in the Performance Plan.
The actual en-route ATFM delay per flight of 0,01 min./flt. was significant below the national target set to 0,08 min./flt. Actual performance is so far in RP3 much better than set in the revised Performance Plan.
Monitoring process for capacity performance
No data available.
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)
No data available.
Additional Information Related to Russia’s War of Aggression Against Ukraine
Initial drop in overflights estimated to around 20%. Some of the traffic have recovered since the initial phase. In general en route capacity has not been affected.
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’s monitoring mentions that Avinor’s IT-department is set on the case, and expected to be solved for calculating the 2023 figures. Traffic at the ensemble of these four Norwegian airports in 2022 was still 10% lower than in 2019.
Average arrival ATFM delays in 2022 was 0.10 min/arr, compared to 0.01 min/arr in 2021. ATFM slot adherence has improved (2022: 99.3%; 2021: 98.6%).
Arrival ATFM delays in 2021 decreased and became marginal at all Norwegian airports. However in 2022 Oslo showed a significant increase in arrival delays (ENGM; 2019: 0.31 min/arr; 2020: 0.05 min/arr; 2021: 0.01 min/arr; 2021: 0.17 min/arr) while the rest of airports registered minimum delays. 51% of the arrival ATFM delays in Norway were attributed to Weather, followed by ATC Staffing issues (39%) at Oslo.
The national target on arrival ATFM delay in 2022 was met.

ATFM slot adherence
All Norwegian airports showed adherence above 98% and the national average was 99.3%. With regard to the 0.7% of flights that did not adhere, 0.3% 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 has slightly deteriorated (ENGM; 2019: 0.14 min/dep.; 2020: 0.05 min/dep.; 2021: 0.06 min/dep.; 2022: 0.10 min/dep.).
According to the Norwegian monitoring report: Pre-departure delay in 2022 (ENGM) is increasing compared to the two previous years during the pandemic, but still below the level before the pandemic (2017-2019).
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 again in 2022 (ENGM: 2020: 5.01 min/dep.; 2021: 6.74 min/dep.; 2022: 12.74 min/dep.) but still resulting in the third lowest value among the RP3 monitored airports. The highest delays per flight were observed in December, averaging more than 20 min/dep.
