Georgia Airspace
Current Status
Georgia's UGGG Tbilisi FIR serves as a critical transit corridor in the South Caucasus, linking Turkey and Europe with Central Asia and the Middle East. The airspace is open to civil aviation and Tbilisi International Airport handles regular international traffic. However, the FIR contains two areas — Abkhazia and South Ossetia — that have been under Russian military occupation since the 2008 war and operate entirely outside Georgian civil ATC control.
Abkhazia, along the Black Sea coast in northwestern Georgia, and South Ossetia, in the north-central region bordering Russia, are recognized by the international community as occupied Georgian territories. Russia maintains military bases in both regions, including air defense systems. There is no coordinated civil ATC service over these territories, creating effectively uncontrolled airspace within the UGGG FIR boundaries. Civil aviation routes are designed to avoid these zones, but the restrictions reduce available routing options through the Caucasus corridor.
GPS interference from multiple sources affects Georgian airspace. Russian military installations in Abkhazia and South Ossetia, combined with broader regional electronic warfare activity related to the Ukraine conflict and Middle Eastern operations, create an unpredictable GPS environment. The mountainous terrain of the Greater and Lesser Caucasus ranges compounds navigation challenges, as terrain-following systems depend on accurate GPS data.
The broader geopolitical context adds uncertainty. Russian-Georgian relations remain tense, with periodic provocations along the occupation line. Georgia's strategic position means that any regional escalation — whether involving Russia, Turkey, Iran, or the Armenia-Azerbaijan dynamic — could rapidly affect transit traffic through the UGGG FIR. The Caucasus corridor's importance as an alternative to Russian overflights has grown significantly since 2022.
Key Risks
Abkhazia and South Ossetia are under Russian military control with no coordinated civil air traffic services. Russian air defense systems are deployed in both regions. Overflying these zones is effectively impossible for civil aviation.
Russian military systems in occupied territories, regional electronic warfare, and Middle Eastern sources create unpredictable GPS degradation. Combined with mountainous terrain, this poses a significant navigation challenge.
Periodic tensions between Russia and Georgia could lead to sudden airspace restrictions or closures. The 2008 war precedent demonstrates how quickly the situation can deteriorate, with airspace closed during hostilities.
The Greater Caucasus range creates minimum en-route altitudes above FL200 on some routes, limiting options during diversions. Terrain-related GPWS alerts can occur when GPS accuracy is degraded.
Recent Events
Georgia reported increased GPS interference over the eastern part of the FIR, coinciding with heightened electronic warfare activity in the broader region.
Azerbaijan Airlines Flight 8243 incident near Aktau, Kazakhstan, raised questions about GPS jamming and air defense risks along Caucasus transit routes. The aircraft had departed Baku and was operating in airspace adjacent to the UGGG FIR.
Increased overflight traffic through the Georgian corridor as airlines continued to avoid Russian airspace, straining ATC capacity on peak routing.
Russia conducted military exercises in South Ossetia, prompting temporary NOTAMs for the areas adjacent to the occupied territory boundary.
EASA & FAA Guidance
EASA does not restrict operations in Georgian airspace but advises operators to avoid overflying Abkhazia and South Ossetia due to the absence of coordinated civil ATC services. EASA safety advisories reference GPS interference risks in the Caucasus region. The FAA has issued guidance recommending that US operators exercise heightened awareness when transiting the UGGG FIR, particularly regarding GPS reliability and the proximity of occupied territories. Both authorities emphasize the importance of contingency planning for GPS loss over mountainous terrain.
