Helsinki-Vantaa Airport
IATA: HEL · ICAO: EFHK · Helsinki, Finland · Last updated: April 2026
Current Status
Helsinki-Vantaa Airport is fully operational and serves as Finnair's primary hub, handling approximately 22 million passengers annually. The airport has three runways and full ILS capability, providing robust all-weather operations. EFHK is a critical node in the Asia-Europe air corridor, historically leveraging Finland's geographic position for efficient polar and near-polar routing.
The airport's eastern approaches are intermittently affected by GPS jamming emanating from Russian territory. The interference primarily impacts flights arriving from or departing toward the east, including routes to Tallinn, the Baltics, and points beyond. The intensity of GPS disruption has fluctuated since the February 2022 cross-border conflict in 2022, with notable peaks during military exercises and periods of heightened tension.
The broader impact on Helsinki's strategic position has been the Russia overfly ban. Since February 2022, EU carriers including Finnair cannot use Russian airspace, adding hours to Asia-bound flights. This has eroded Helsinki's key competitive advantage as the shortest Europe-to-Asia connection, though Finnair continues to operate Asian routes via longer southern and Arctic routings.
Key Risks
Russian-origin GPS jamming affects flights operating to and from the east. The interference zone extends across southeastern Finland and into Estonian and Latvian airspace. During active jamming, GPS-dependent approaches and departures on easterly headings may be unreliable.
In 2024, Finnair suspended its Helsinki-Tartu route after a GPS jamming event caused a flight to fail its approach at Tartu, where only GPS-based approaches are available. This incident demonstrated how GPS denial can make smaller airports effectively inaccessible, increasing traffic concentration at larger facilities like Helsinki.
Asia-Europe polar routes that transit near Russian airspace boundaries depend on GPS for navigation over areas with limited ground-based nav aid coverage. GPS jamming at high latitudes could affect the safety and efficiency of these routings, though alternative navigation methods are available.
The closure of Russian airspace to EU carriers has added 2-4 hours to Finnair's Asian routes, increasing fuel costs and reducing schedule competitiveness. This structural challenge affects Helsinki's hub economics, though the airport remains a significant European gateway.
Recent Events
GPS interference reported on eastern departures from HEL for several consecutive days. Fintraffic ANS (Finnish ATC) issued NOTAMs and routed departing traffic on westerly headings where possible.
Finnair announced expanded use of enhanced inertial navigation systems across its fleet to mitigate GPS denial effects on Baltic and Eastern European routes.
Extended GPS jamming event affected all three Baltic states plus southern Finland simultaneously. Helsinki operations continued using ILS approaches. EUROCONTROL issued regional advisory.
Finnair suspended Helsinki-Tartu route after GPS interference caused a failed approach at Tartu. The incident was attributed to Kaliningrad-origin jamming and prompted EASA to issue a Safety Information Bulletin on Baltic GPS denial.
Airlines Operating
Finnair (primary hub), Norwegian Air, SAS, Ryanair, easyJet, Lufthansa, British Airways, Turkish Airlines, Japan Airlines (codeshare), and numerous European and Asian carriers. Finnair's oneworld alliance connections make Helsinki a transfer hub between European and Asian networks.
Despite the Russia overfly challenge, Finnair continues to operate routes to Tokyo, Osaka, Seoul, Beijing, Shanghai, Singapore, Bangkok, and Delhi via southern and Arctic routings.
Approach & Navigation
EFHK has ILS (CAT IIIB) on runways 04L and 04R, and ILS CAT I on runway 15. VOR/DME approaches are available as conventional backups. The airport sits at 179 feet (55 m) elevation on flat terrain north of Helsinki, with no significant terrain obstacles on any approach path.
The CAT IIIB capability ensures operations can continue in near-zero visibility conditions without GPS dependence. Finnish authorities have prioritized maintaining conventional nav aid infrastructure precisely because of the GPS jamming environment. Crews should brief ILS approaches as primary when operating to or from Helsinki during periods of reported GPS interference.
