PRB monitoring

▪ Latvia 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 37% below 2019 levels in Latvia in 2022.

▪ The number of ATCOs in OPS is not expected to change significantly by the end of RP3, with the actual plan remaining below the 2022 plan in Riga ACC.

▪ The yearly total of sector opening hours in Riga ACC was 6,912 in 2022, showing a 7.1% increase compared to 2021. Sector opening hours are 19.4% below 2019 levels.

▪ Riga ACC registered 20.12 IFR movements per one sector opening hour in 2022, being 5.2% below 2019 levels.

▪ Latvia registered nearly zero minutes of average airport arrival ATFM delay per flight in 2022, achieving the local target of 0.02 minutes.

▪ Compared to 2021, average arrival ATFM delays in Latvia were 96.09% lower in 2022, while the number of IFR arrivals increased by 42.88%.

▪ The main reason for delays was ATC disruption, accounting for 100% of delays.

Summary of capacity performance

Latvia experienced an increase in traffic from 163k flights in 2021, with zero ATFM delay, to 190k flights in 2022, also with zero en route ATFM delay.

Traffic levels were still substantially below the 295k flights in 2019.

NSA’s assessment of capacity performance

After two years of COVID-19 pandemic, along with the other Baltic states, Latvia was hot by the aftermath of Russian invasion in Ukraine. Sanctions imposed by EU, along with the sanctions imposed by Russia against EU, changed the traffic flows dramatically.

Traffic flow between Russia to Europe stopped, while the Europe ↔︎ China and Europe ↔︎ SE Asia segments dramatically dropped. Due to restrictions on overflying EU airspace, Russian aircraft operators started to fly over high seas in the Baltic sea in order to connect Kaliningrad to mainland Russia. This increased the traffic in Latvian delegated airspace, but has a negative impact on the receivables of the ANSP.

Due to Russian invasion in Ukraine and the EU sanctions against the Russia and Belorussia, air traffic flows have remained at approximately 60% of 2019 air traffic level.

No capacity issues have been identified.

Monitoring process for capacity performance

Capacity monitoring takes place during annual inspections, in addition to regular monthly statistical data sent by the LGS to the LV CAA.

Capacity planning

Capacity planning measures by LGS are checked during annual inspections.

Application of Corrective Measures for Capacity (if applicable)

No data available.

Arrival ATFM delay (KPI#2)

Focus on arrival ATFM delay

Latvia identified 4 airports as subject to RP3 monitoring. In accordance with IR (EU) 2019/317 and the traffic figures at these 4 airports, pre-departure delays are not monitored and the capacity performance monitoring focuses on arrival ATFM delay and slot adherence. Traffic at these Latvian airports in 2022 was still 36% lower than in 2019, regardless of a 43% increase with respect to 2021.

Average arrival ATFM delays in 2022 was 0.00 min/arr, compared to 0.02 min/arr in 2021. ATFM slot adherence has improved (2022: 99.6%; 2021: 98.8%).

Average arrival ATFM delays in 2022 were zero at all three Latvian airports.

The national target on arrival ATFM delay in 2022 was met.

ATFM slot adherence

Riga’s ATFM slot compliance was 99.6%, a further improvement with respect to the already good value in 2021 (98.8%). With regard to the 0.4% of flights that did not adhere, 0.3% was early and 0.1% was late. EVVA did not have any regulated departures and EVLA had only 4, with a 100% slot adherence.

According to the Latvian monitoring report: LGS provides to the CAA monthly summary of the ATFM slot adherence data. In comparison to previous years, ATFM slot adherence has remained very high.

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 Latvia.
