Greece Airspace
Current Status
The Athens FIR (LGGG) is fully operational with no restrictions on international traffic. Greece serves as a major destination for European tourism and a transit corridor for flights between Europe and the eastern Mediterranean. Athens International Airport and numerous island airports handle substantial seasonal traffic throughout the year.
The primary concern within the LGGG FIR is GPS interference affecting the eastern Aegean islands. Spoofing and jamming originating from Turkey and the broader Syria/Iraq conflict zone spills westward into Greek airspace, particularly affecting islands such as Rhodes, Kos, Lesbos, and Samos. Pilots operating to these destinations have reported intermittent GPS anomalies, including position displacement and signal loss during approach phases.
NATO military exercises, particularly around the Souda Bay naval base in Crete, generate periodic NOTAMs that affect portions of the southern LGGG FIR. These exercises can restrict airspace at certain flight levels and require rerouting for civil traffic. The exercises are well-coordinated with Greek ATC but can coincide with peak tourist season traffic.
Mainland Greece and the western Aegean remain largely unaffected by GPS interference. The risk is geographically concentrated in the eastern fringe of the FIR and is seasonal in intensity, often correlating with military activity in neighboring regions.
Key Risks
Spoofing originating from Turkey and the Syria/Iraq conflict zone affects GPS reliability at eastern Greek islands. Aircraft on approach to Rhodes, Kos, and Lesbos report intermittent position errors and signal degradation.
NATO exercises near Crete and in the eastern Mediterranean periodically restrict portions of the FIR. These are well-coordinated but can cause rerouting during peak traffic periods.
The overlapping Greek and Turkish FIRs in the Aegean create a uniquely complex ATC environment. Coordination between Athens and Ankara centers is essential for safe transit.
Periodic tensions between Greece and Turkey over Aegean sovereignty can affect airspace coordination. While direct impact on civil aviation remains limited, escalation could change the risk profile.
Recent Events
Pilots reported GPS anomalies on approach to Rhodes, with position errors consistent with spoofing from southeastern Turkey.
NATO exercise near Souda Bay, Crete generated NOTAMs restricting portions of southern LGGG FIR at FL250-FL400 for three days.
EUROCONTROL noted increased GPS interference reports from aircraft transiting the eastern Aegean, correlating with heightened activity in Syria.
Peak tourist season saw record traffic at Aegean island airports; no GPS-related operational disruptions reported on the mainland.
EASA & FAA Guidance
EASA does not maintain a CZIB for Greek airspace. However, broader eastern Mediterranean GPS interference advisories encompass the eastern Aegean region. EASA recommends operators verify ILS availability at eastern Greek island airports and maintain awareness of GPS reliability during approach planning. The FAA does not restrict US carrier operations in the LGGG FIR. Both authorities monitor the situation as part of ongoing regional GPS interference assessments.
