Capacity - Latvia

PRB monitoring

▪ LGS registered zero minutes of average en route ATFM delay per flight during 2020, thus meeting the local breakdown value of 0.06.

▪ Delays must be considered in the context of the traffic evolution: IFR movements in 2020 were 56% below the 2019 levels in Latvia.

▪ Latvia reported no capacity issues and an increase of 5% in ATCO FTE numbers in 2020 compared to 2019 values.

▪ The yearly total of sector opening hours in Riga ACC was 20,959, showing a 27.3% decrease compared to 2019.

Summary of capacity performance

Latvia experienced a traffic reduction of 56% from 2019 levels, to 129k flights. The traffic level was accommodated with zero en route ATFM delays to airspace users.

NSA’s assessment of capacity performance

No capacity issues were present in 2020 due to COV19.

Monitoring process for capacity performance

Oversight and monitoring performed in accordance with EU reg 255/2010.

Capacity planning

So far the capacity planning has been consistent and appropriate, considering unplanned Cov19 pandemic impact.

Terminal performance

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.
After a traffic increase of 28% along RP2 (2019 vs 2015), traffic at these Latvian airports decreased by 59% in 2020 compared to 2019. Only Riga airport has ATC services. EVVA, EVJA are general aviation aerodromes, while EVLA has only AFIS with limited ops hours.
Zero arrival ATFM delays were registered in 2020 and slot adherence was 98.4%.

No arrival ATFM delay was observed at the Latvian airports in 2020, in line with the performance during RP2.

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.

Focus on performance indicators at airport level

ATFM slot adherence

Only Riga had regulated departures in 2020. With the drastic drop in traffic, these regulated departures from Riga also virtually disappeared as of April. The annual figure is therefore driven by the performance in the first trimester.
Riga’s ATFM slot compliance was 98.4%. With regard to the 1.6% of flights that did not adhere, 1.4% was early and 0.2% was late.

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.
