Risk Level: Two - Danger exists

[ about risk levels ]
There is an ongoing active conflict in Ukraine between Russian and Ukrainian forces. Ukraine closed its entire airspace to all civil traffic on Feb 24. Russia and Belarus have closed large sections of their own airspace near to their FIR boundaries with Ukraine. Moldova initially closed all their airspace too, but have since opened a section on their western border with the LRBB/Bucharesti FIR for flights to LUKK/Chisinau airport.

The primary risk is an unintended targeting of civil aircraft by military near the Moldova-Ukraine border, including misidentification (as with MAS17, UIA752), or confusion. The secondary risk is from spillover from the conflict such as Russian drones and missiles.

Major events:
Feb 2023: The LUUU/Chisinau FIR closed temporarily following reports of Russian drones infringing its airspace. Earlier in the month, at least two missiles also transited Moldova during a major military operation in Ukraine. Spill over risks from the conflict are being frequently reported.
