This CZIB is issued on the basis of information available to EU Member States and EU institutions. Considering the hazardous security situation resulting from ongoing high intensity military operations, political instability and the presence of terrorist groups with access to sophisticated anti-aviation weaponry, the risk posed to operations within the airspace of Yemen, Sana’a FIR, at all altitudes, is assessed to be HIGH. The risk for all routes located in the maritime part of FIR SANAA (OYSC) east of route B400 (included) is assessed to be MEDIUM.
EASA recommends to avoid operations in the airspace of Yemen, Sana’a FIR, at all altitudes and flight levels, except for all routes located in the maritime part of FIR SANAA (OYSC), east of route B400 (included), where operators are recommended to exercise caution at all flight levels.
Air operators should closely monitor airspace developments in the region and follow all available aeronautical publications issued by Yemen, or on their behalf by the Aviation Authorities of the neighbouring States, including information shared through the European Information Sharing and Cooperation Platform on Conflict Zones, alongside available guidance or direction from their national authorities.
