PRB monitoring
▪ LFV registered 0.01 minutes of average en route ATFM delay per flight during 2020, thus meeting the local breakdown value of 0.15.
▪ Delays must be considered in the context of the traffic evolution: IFR movements in 2020 were 57% below the 2019 levels in Sweden.
▪ Sweden reported no capacity issues and a 1% decrease in ATCO FTE numbers in 2020 compared to 2019.
▪ Delays were driven by disruptions (technical issues).
▪ The share of delayed flights with delays longer than 15 minutes in Sweden increased by 3.28 p.p. compared to 2019.
▪ The yearly total of sector opening hours in Malmo ACC was 48,401, showing a 15.8% decrease compared to 2019. The yearly total of sector opening hours in Stockholm ACC was 27,645, showing a 37.6% decrease compared to 2019.
▪ Malmo ACC registered 5.02 IFR movements per one sector opening hour in 2020, being 50.1% below 2019 levels. Stockholm ACC registered 6.1 IFR movements per one sector opening hour in 2020, being 34.2% below 2019 levels.
Summary of capacity performance
Sweden experienced a traffic reduction of 57% from 2019 levels, to 351k flights. The traffic level was accommodated with less than 3k minutes of en route ATFM delays to airspace users. Almost 80% of ATFM delays were attributed to ATC equipment in February 2020.
NSA’s assessment of capacity performance
Performance is better than target as a result of the reduction in traffic. The delays reported refer to the period January - February.

Malmo ACC: Reporting according to the definition used in ACE.
Stockholm ACC: Reporting according to the definition used in ACE.
Sweden only has Stockholm (ESSA) airport subject to RP3 monitoring for which the APDF is successfully established and the monitoring of the capacity indicators can be performed. Nevertheless, the quality of the reporting does not allow for the calculation of the ATC pre-departure delay, with more than 60% of the reported delay not allocated to any cause.
Traffic at this airport in 2020 decreased by 63% with respect to 2019. This drop in traffic also resulted in zero average arrival ATFM delay for Stockholm in 2020. The slot adherence was 98.1%.
Only 203 min of arrival ATFM delay were registered at Stockholm in 2020, in January, resulting in an average 0 min/arr for the year. This is a significant improvement with respect to the 0.32 min/arr in 2019.
The provisional national target on arrival ATFM delay in 2020 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.

ATFM slot adherence
With the drastic drop in traffic, regulated departures from Stockholm virtually disappeared as of April. The annual figure is therefore driven by the performance in the first trimester.
Stockholm’s ATFM slot compliance was 98.2%. With regard to the 1.8% of flights that did not adhere, 0.7% was early and 1.1% 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 Stockholm.
However, there are several quality checks before EUROCONTROL can produce the final value which is established as the average minutes of pre-departure delay (delay in the actual off block time) associated to the IATA delay code 89 (through the APDF, for each delayed flight, the reasons for that delay have to be transmitted and coded according to IATA delay codes.
However, sometimes the airport operator has no information concerning the reasons for the delay in the off block, or they cannot convert the reasons to the IATA delay codes. In those cases, the airport operator might:
- Not report any information about the reasons for the delay for that flight (unreported delay)
- Report a special code to indicate they do not have the information (code ZZZ)
- Report a special code to indicate they do not have the means to collect and/or translate the information (code 999)
To be able to calculate with a minimum of accuracy the PI for a given month, the minutes of delay that are not attributed to any IATA code reason should not exceed 40% of the total minutes of pre-departure delay observed at the airport.
Finally, to be able to produce the annual figure, at least 10 months of valid data is requested by EUROCONTROL.
The share of unidentified delay reported by Stockholm was above 40% between April and June 2020, preventing the annual calculation of this indicator, as there were only 9 months of valid data. Stockholm usually has proper reporting.
All causes pre-departure delay
The total (all causes) delay in the actual off block time at Sweden in 2020 was 8.34 min/dep. The higher delays per flight were observed in May due to the lower traffic and extraordinary circumstances.
This performance indicator has been introduced in the performance scheme for the first time this year, so no evolution with respect to 2019 can be analysed.
