Middle East Airspace: GPS Spoofing, Closures & Regional Disruptions

The Middle East sits at the intersection of three continents, making it one of the most heavily transited airspace regions for international aviation. Routes between Europe and the Gulf, Europe and South Asia, and Europe and East Africa all cross multiple FIRs in this region. When disruptions occur, the geographic concentration means they rarely stay contained within a single FIR.

Since 2023, IATA has publicly reported a 175% increase in navigation disruption incidents in this region. The primary vector is GPS spoofing, which according to Eurocontrol data has been documented across the eastern Mediterranean, the Levant, Iraq, and the Persian Gulf. Unlike jamming (which simply denies GNSS signals), spoofing feeds false position data to aircraft receivers, potentially triggering GPWS false alerts and causing autopilot deviations. EASA has published multiple Safety Information Bulletins (SIBs) addressing these events.

The region has also experienced an escalating pattern of cascade FIR closures. In February 2026, a military exchange led to the simultaneous closure of 12 FIRs across the Persian Gulf and surrounding area, according to publicly available NOTAMs. This represented the largest single cascade closure event documented in commercial aviation, forcing real-time rerouting of hundreds of flights. The event followed a pattern established in April and October 2024, when Iranian-Israeli exchanges triggered multi-FIR shutdowns covering Jordan, Iraq, and Iran.

War risk insurance premiums for the region have escalated significantly, as documented by industry sources. Several underwriters have expanded exclusion zones or imposed surcharges for overflying affected FIRs. Israel's government established an $8 billion sovereign guarantee to maintain insurance coverage for its national carrier and Ben Gurion operations, a measure publicly reported by financial media. Rerouting costs for European and Asian carriers avoiding the region have been estimated in publicly available industry analyses at hundreds of millions of dollars annually, primarily from increased fuel burn on longer routings via the Caucasus, Central Asia, or African coastal corridors.
