Sukhoi Civil Aircraft Company said its first Sukhoi Superjet 100 is ready to undergo a certification flight testing which is expected to begin after the completion of its factory tests. The aircraft now has 40 flights and 100 hours, gaining a maximum altitude of 11,300 meters at a speed of 0.7 max. The Aviation Register of Interstate Aviation Committee concluded a technical review of the factory flight tests. These tests proved that all aircraft systems are able to work smoothly and efficiently at all design modes within a total range of flying speeds, altitudes, angles and balances. This stage estimated flight and technical performance of the aircraft as well as its aerodynamic characteristics, including takeoff/landing performance, and a climb rate.
