The second stage of the MC-21-300 in-plant development tests program commenced on September 13. The modified airplane systems worked without complaint during the flight, which lasted about two hours.
In the course of preparations for the second stage of MC-21-300 tests, strain gauges were mounted on the aircraft, enabling the accurate measurement of loads on the structure. Also by the results of the first flight test stage, the software has been corrected.
The main goal of this stage of testing is to extend the range of flights by mass, centering, speed and altitude.
