Capacity - Estonia

PRB monitoring

▪ Estonia registered zero minutes of average en route ATFM delay per flight during 2022, thus achieving the local target value of 0.03.

▪ The average number of IFR movements was 38% below 2019 levels in Estonia in 2022.

▪ The number of ATCOs is not planned to change significantly by the end of RP3. The actual values of ATCOs in OPS remained below the plan in 2022.

▪ The share of delayed flights with delays longer than 15 minutes in Estonia increased by 28.57 p.p. compared to 2021 and was higher than 2019 values.

▪ The yearly total of sector opening hours in Tallinn ACC was 10,116 in 2022, showing a 15.4% increase compared to 2021. Sector opening hours are 20.3% below 2019 levels.

▪ Tallinn ACC registered 13.15 IFR movements per one sector opening hour in 2022, being 24.4% below 2019 levels.

Summary of capacity performance

Estonia experienced an increase in traffic from 109k flights in 2021, to 142k flights in 2022 with zero ATFM delay. However, traffic levels were still substantially below the 227k flights in 2019.

NSA’s assessment of capacity performance

2021 was the year of global recovery from the COVID-19 pandemic. We were already optimistic about 2022, and suddenly Russia started the war in Ukraine.

Regarding the controlled traffic, the year 2022 turned out to be much more complicated than expected. In response to Russia’s military aggression against Ukraine, which started on 24 February 2022, the European Union took restrictive measures prohibiting Russian airlines, aircraft registered in Russia and aircraft owned, chartered or otherwise controlled by natural or legal persons, entities or bodies of Russia from landing, taking off from or overflying the territory of the European Union. Due to these measures, air traffic between Europe and Asia in the Estonian airspace decreased sharply.

In 2022, the number of IFR flights controlled was 142,277 compared to the 175,000 flights forecast in the performance plan. The volume of service units related to IFR movements to which en route navigation services were provided was 41% lower than the forecast: 428,511 vs. 726,854 service units. On the other hand, due to the sanctions resulting from the war between Russia and Ukraine, there was a significant increase in the volume of air traffic in the airspace above the international waters for which we are responsible.

En route capacity targets of Estonia, in minutes of ATFM delay per flight for 2022 was 0.03 min. Actual ATFM delay per flight for 2022 is recorded 0.0 min

Terminal performance

Arrival ATFM delay (KPI#2)

Estonia identified two airports, Tallinn and Tartu, as subject to RP3 monitoring. In accordance with IR (EU) 2019/317 and the traffic figures at these 2 airports, pre-departure delays are not monitored and the capacity performance focuses on arrival ATFM delays and slot adherence.
Traffic at these Estonian airports in 2022 was 23 % lower than in 2019 even if it increased by 49% with respect to 2021.

Like in the rest of RP3, no arrival ATFM delays were observed in the entire 2022 at these two airports and slot adherence remained very high (2022: 98.3%; 2021: 98.2%).

No arrival ATFM delay was observed at the Estonian airports (Tallinn and Tartu) in 2022.
3. Arrival ATFM Delay – National TargetThe national target on arrival ATFM delay in 2022 was met.

Tallin showed very high slot adherence (98.6%) and at Tartu there only 12 regulated departures in 2022 (none in 2020 and 2021), from which 6 departed outside of the STW.
The national average was 98.3%. With regard to the 1.7% of flights that did not adhere, 0.9% was early and 0.3% was late above 95% and the national average was 98.8%, an improvement with respect to 2021 (97.4%). With regard to the 1.2% of flights that did not adhere, 0.6% was early and 1.1% was late.

According to the Estonian monitoring report: Performance in this area is the same as previous years, no special measures are taken.

ATFM slot adherence

This indicator is not monitored for airports below 80 000 IFR movements annual average during the 2016-2018 period, so it is not monitored for any airport in Estonia.

ATC pre-departure delay

This indicator is not monitored for airports below 80 000 IFR movements annual average during the 2016-2018 period, so it is not monitored for any airport in Estonia.
