The plane was in the sky for about four hours. The flight took place at various heights and was accompanied by equipment tests under real conditions. The crew included test pilots and engineers, including a test pilot, the hero of Russia Oleg Kononenko and Honorable Test Pilot Andrei Voropaev.
The aircraft is already equipped with the majority of Russian components. On board, domestic navigation systems, computers, radio communication, control panels, lighting equipment and auxiliary electrical power plant, air conditioning and pressure editing systems were established. The components of Russian production are also used in the power supply system, hydraulic and chassis.
Currently, only three imported systems remained in the design: brakes, drivers and generators. However, in the near future, a completely localized version of the primer is planned to connect to the program – all systems and units will be Russian production. This version of the aircraft is already under the last assembly phase.
