The SJ-100 aircraft with Russian systems overcame the practical height ceiling

The Russian prototype of the Superjet (SJ-100) aircraft, which was created under the import substitution program with domestic systems and a Russian-French engine, overcame the practical ceiling of its height of 12.2 thousand meters during the flight.
