On 20 July 2018, the second MC-21-300 test aircraft, participating in the flight test program, flew from Irkutsk to the airfield “Ramenskoye” of Flight Research Institute M.M. Gromov (Zhukovsky, Moscow Region). The flight lasted 6 hours.

The flight test program of the second MC-21-300 aircraft started on 12 May 2018, at the airfield of the Irkutsk Aviation Plant, a branch of Irkut Corporation. While performing flights from this airfield with a total duration of nearly 14 hours, the aircraft reached altitude of 12,000 m, speed of 0.8 M, true speed of 850 km/h.

Within the framework of flight tests, the following works were performed:

  • stability and controllability characteristics of the aircraft in various high-lift configurations with extended and retracted landing gear were confirmed;
  • the measuring system of altitude/speed parameters was calibrated to match them with their actual in-flight values;
  • various modes of power plant operation were verified, including in-flight shutdown and restart of the engine;
  • aircraft systems operability was checked.

Further testing of two MC-21-300 test aircraft will be carried out on the basis of Flight Testing Facility (FTF) of Yakovlev Design Bureau.
