Russia announced the introduction of a dangerous zone for civil aviation in the area over the Black Sea and Crimea, this was published in the operational information on changes in the rules for conducting and ensuring flights (NOTAM).
In total, the Russian Federation has issued three NOTAMs. They are valid until April 24tj, with minor differences.
A number of air routes in the Simferopol flight information area over the Black Sea were completely blocked.
At the same time, the flight zone over the Crimean peninsula do not overlap.
As follows from the NOTAM, in some areas there is an overlap only above 11,900 m (that is, above the level of civil aviation flights), in others – above 6,100 m, and somewhere the overlap of zones is from sea level.
Earlier on April 20th, the press service of the Black Sea Fleet reported that, as part of a control check of the fleet forces during the winter training period, exercises were held in which more than 20 ships and boats of the Black Sea Fleet and three squadrons of attack aircraft of the Air Force and Air Defense of the Southern Military District.
Prior to that, the US Federal Aviation Administration (FAA) issued a NOTAM, in which it recommended that US airlines operate with extreme caution over certain regions of Russia and Ukraine.
It is recommended to take special care when flying “to, from, within or over” the flight information regions (FIR) of Kiev, Dnieper (formerly Dnepropetrovsk) and Simferopol, as well as in the FIR regions of Moscow and Rostov-on-Don located within 100 nautical miles from them. Both documents were issued in connection with “possible risks to flight safety associated with the escalation of regional tensions between the Russian Federation and Ukraine, which could potentially lead to cross-border clashes without prior notice, increased military activity and / or conflict.”
Additionally, Russian state media reported that Moscow intends to close parts of the Black Sea to foreign military and official ships for six months, which could affect access to Ukrainian ports in the Sea of Azov, which is connected to the Black Sea through the Kerch Strait.
The US condemned this move.
“This represents yet another unprovoked escalation in Moscow’s ongoing campaign to undermine and destabilise Ukraine,” State Department spokesman Ned Price said in a statement.
“This development is particularly troubling amid credible reports of Russian troop buildup in occupied Crimea and around Ukraine’s borders, now at levels not seen since Russia’s invasion in 2014,” he added.
