Finnair Adapts to Constant GPS Interference

Finnair's pilots are now trained to manage frequent GPS interference in Baltic airspace, a daily operational challenge. The airline's CEO confirmed these adaptations are necessary due to ongoing electronic warfare concerns in the region.

Since Russia's invasion of Ukraine, the scale of GPS signal disruption over the Baltic Sea has significantly increased. This has led Finnair to reroute flights, avoiding Russian and Belarusian airspace and increasing exposure to the Baltic region.

In one instance earlier this year, Finnair had to suspend flights to Tartu, Estonia, for approximately a month because GPS interference prevented safe approaches. Despite modern aircraft having multiple backup navigation systems, the intensity and regularity of the interference are growing.

Airline leaders outside Europe have expressed surprise at the daily nature of this problem but are keen to learn from Finnair's successful adaptation strategies. The airline's proactive measures are becoming a case study for others facing similar emerging challenges.
