The observation flight over Finland will be carried out from 16 to 20 September 2019 from the Zaventem Open Skies airfield. The maximum flight range will amount to 945 km.

The Russian observation aircraft will fly along the agreed route, and the Benelux representatives on board will monitor the use of special equipment and compliance with the provisions of the Treaty on Open Skies.

Observation flights within the framework of the treaty are carried out in order to promote greater openness and transparency in the military activities of the participating States, as well as to enhance security through strengthening confidence-building measures.
