As of 24 February 2022, due to high safety risks caused by military activity in Ukraine, eastern European airspace in some areas has been restricted (i.e. closed) for civil aviation operations.
The European Business Aviation Association (EBAA) reports: Based on information received by EUROCONTROL and EASA, Air operators are reminded that this is now an active conflict zone. Under these circumstances, the aforementioned airspace and critical infrastructure, including airports, are exposed to military activities which result in safety risks for civil aircraft.
In particular, there is a risk of both intentional targeting and misidentification of civil aircraft. The presence and possible use of a wide range of ground and airborne warfare systems poses a high risk for civil flights operating at all altitudes and flight levels.
Operators should take this information and any other relevant information, along with any available guidance or directions from competent authorities, as appropriate, into account in their own risk assessments when deciding whether to operate within the aforementioned airspace and landing and departures from airports located in the affected airspace.
Additionally, as a precautionary measure, operators should exercise extreme caution and avoid using the airspace within 100nm of the Bielorussian and Russia-Ukraine border.
UPDATE 25 February: the affected airspace to the whole of FIR Rostov. In addition, the buffer along the border with Ukraine inside FIR Moscow has been broadened to 200 NM (previously 100 NM). This extension reflects the operational reality and takes account of the assessed risk posed by the threat of missile launches to and from Ukraine.
