The European Union Aviation Safety Agency (EASA) has released an updated warning to aircraft operators concerning the risks associated with interference in navigation systems due to signal spoofing and jamming. This announcement, made on Friday, highlights increased threats in airspace near conflict zones.
In its third edition of the safety information bulletin (SIB), EASA addresses global navigation satellite system (GNSS) outages and modifications that can lead to a decline in communication, navigation, and surveillance capabilities. To provide more timely threat information, EASA has launched a new platform for updating operators on GNSS system issues within affected flight information regions (FIRs). The areas currently of most concern include the southern and eastern Mediterranean Sea, the Middle East, regions around the Black Sea, parts of Eastern Europe, as well as the Baltic Sea and Arctic region.
Jamming interferes with signals used by navigation systems while spoofing sends incorrect data to an aircraft's onboard receiver. The updated guidance revises an earlier SIB issued in November and offers specific recommendations for regulators, air traffic management, air navigation service providers, and aircraft operators.
