THE SECOND MC-21-300 AIRCRAFT:

FLIGHT TESTS STARTED

3

• The maiden flight was performed on 12 May 2018 from the airfield of Irkutsk Aviation Plant.

• In production of the second test aircraft, testing results of the first test sample were taken into account.

• The white color has been selected for painting to demonstrate high quality of airframe surface and precision of

joints of fuselage sections.

• While flying in Irkutsk, the aircraft has accumulated nearly 14 flight hours and achieved altitude of 12,000 m, speed

of 0.8M, true speed of 850 km/h.

• Stability and controllability characteristics of the aircraft in various high-lift configurations, with extended and

retracted landing gear have been estimated.

• The measurement system of altitude/speed parameters has been calibrated to match them with their real flight

values.

• Various modes of the power plant operation have been tested, including turning-off and re-starting engine in flight.

• Operability of all aircraft systems has been checked.
