Latvia Airspace
Current Status
The Riga FIR (EVRR) is fully operational and serves as the central transit corridor for traffic moving between the three Baltic states. Latvia sits geographically between Estonia to the north and Lithuania to the south, and its airspace links the broader Scandinavian-Baltic route structure. Riga International Airport (EVRA) is the busiest airport in the Baltic states and a hub for airBaltic, handling connections across Europe.
Like its Baltic neighbors, Latvia is affected by GPS jamming originating from the Russian exclave of Kaliningrad, located approximately 250 kilometers to the southwest. The interference pattern across the EVRR FIR is consistent with the broader Baltic jamming corridor, with GPS reliability degrading primarily in the southern and eastern portions of the FIR. Riga Airport, located on the Gulf of Riga coast, experiences intermittent GPS degradation during peak jamming events.
Latvian aviation authorities (LGS) and the Latvian ANSP coordinate closely with Estonian and Lithuanian counterparts through the Baltic FAB (Functional Airspace Block) to share GPS interference data and harmonize operational responses. This regional coordination ensures consistent procedural standards across all three Baltic FIRs.
Riga Airport maintains fully operational ILS approaches on its primary runways, providing reliable all-weather capability independent of GPS. The airport's coastal location and flat surrounding terrain reduce the compounding risk that GPS denial creates in mountainous environments. Regional airports within Latvia have more limited instrument approach infrastructure and are more vulnerable to GPS degradation.
Key Risks
Persistent electronic interference from the Russian exclave degrades GPS reliability across the southern and eastern EVRR FIR. The jamming affects RNAV approaches and en-route navigation accuracy.
Smaller Latvian airports with GPS-dependent approaches face operational limitations during jamming events. Liepaja and Ventspils, closer to Kaliningrad, are particularly affected.
As the central Baltic transit FIR, Latvia handles through-traffic between Scandinavia and southern Europe. GPS interference adds complexity to an already busy corridor during peak periods.
GPS jamming intensity in Latvian airspace tracks closely with broader Baltic patterns and serves as a barometer for regional electronic warfare activity. Changes in interference levels often signal broader military developments.
GPS jamming can produce erroneous position data that triggers false Ground Proximity Warning System alerts during approach phases, requiring crew awareness and procedural readiness.
Recent Events
Increased GPS jamming reported across the EVRR FIR, with Riga approach controllers issuing verbal warnings to arriving traffic about potential GPS unreliability.
Baltic FAB partners published joint GPS interference mitigation procedures, standardizing crew briefing requirements across Estonian, Latvian, and Lithuanian airspace.
GPS jamming event affected southern Latvia during peak traffic period, causing minor delays on RNAV arrivals at Riga before ILS transitions were coordinated.
NATO reported GPS interference from Kaliningrad at sustained high levels across all three Baltic FIRs, with Latvia experiencing its highest recorded jamming duration.
EASA & FAA Guidance
EASA addresses Latvian airspace GPS interference within its Baltic region Safety Information Bulletins, advising operators to confirm ILS availability at Latvian airports and prepare for GPS-denial contingencies. The FAA does not restrict US carrier operations in the EVRR FIR but references the Baltic jamming situation in European airspace advisories. The Latvian Civil Aviation Agency participates in regional coordination through the Baltic FAB framework, ensuring harmonized standards with neighboring states.
