After being prepared at the ground test station of the Sukhoi Civil Aircraft Company Komsomolsk branch the aircraft had been tagged to the starting point of the Komsomolsk-on-Amur Aircraft Production Association runway. The crew – Alexander Yablontsev and Leonid Chikunov – started the engines.

The aircraft took off at 16:47 local time, gaining the altitude of 1200 m. At this altitude the crew evaluated controllability and stability characteristics of the aircraft in bank and pitch within the range of ±20? and 0? - 15 respectively as well as varying the altitude.

At the altitude of 900 – 1200 m the pilots imitated landing – so called "landing on the cloud": descending from 1200 m to the level of 900 with the vertical speed of -5m/sec, leveling the aircraft at the altitude of 900 m and further on accending back onto 1200 m.

Gaining the altitude of 1200 m the pilots leveled the aircraft and completed a box pattern span at the velocity of 260 – 280 km/h.

Next flight over the takeoff runway was performed at the altitude of 150 m – after descending from 900 m at the velocity of 260 km/h and further ascending up to 900 m.

After having flown over the takeoff runway the expected four times at different heights the first flight Sukhoi Superjet 100 successfully landed to the factory runway at 17:54 local time. The debut flight lasted 1 hour 5 minute. The aircraft gained maximum velocity of 333 km/h and maximum altitude – 1200 m.

Saturday, May 24, 2008 was the day for the Sukhoi Superjet 100 second flight. This time the aircraft spent 2,5 h in flight, gaining maximum altitude of 3000 m and maximum velocity of 410 km/h. During the second flight the pilots broadened the programme by retracting and extending landing gear and external control surfaces, besides further evaluation of general aircraft characteristics in broader range on heights and velocities.

According to Alexander Yablontsev, SCAC's Chief Pilot, "the aircraft met our expectations as of general, controllability and stability characteristics, as well as engine and systems operation. By the piloting comfort and easiness even at this test stage it can be compared to the existing modern aircraft. I'm sure, that remote control system, its quality will outbeat the rivals". Thanks to the engineering simulator, employed for remote control system testing "there were no surprise in piloting, on the contrary, I was surprised, how exact the match was".
