IRKUT reports today that flight test experts from the European Union Aviation Safety Agency (EASA) completed the first flight session of the MC-21-300 certification program. During the certification tests, the behavior of MC-21-300 aircraft was evaluated in various modes, including high angles of attack and stalling. Flights were from 2.5 to 4 hours and performed at altitudes from 3 to 10 km.
The aircraft was piloted by EASA test pilots. A test pilot from the Yakovlev Design Bureau (a branch of Irkut Corporation) monitored the performance of flight modes. Flight crews included Russian and EASA flight test engineers to analyze flight parameters. In September 2018, EASA test crew completed a special course in theoretical and practical training, as a result of which they obtained permission to fly on MC-21-300 aircraft.
