After the flight, the 103 aircraft of the C919 aircraft will be transferred to Xi’an Yanliang in time to carry out test flight in subjects such as flutter, airspeed calibration, load, stability and performance. At present, two test aircrafts of the C919 aircraft have been launched in Xi’an Yanliang, Shandong Dongying and Jiangxi Nanchang.

With a passenger capacity of more than 160 and a voyage of more than 5,000 kilometers, the C919 is one of the most advanced passenger aircraft in the world. It would be inducted into commercial use by 2021.

According to the plan, the C919 will manufacture a total of six test machines, of which the first three would mainly be responsible for test flight in terms of performance, structure and maneuverability; the fourth is mainly for flight test in avionics and lighting; the fifth is mainly for cabin test. Test environment for internal environment control, cabin system, high temperature and cold, etc.; the sixth is responsible for flight test subjects such as cabin system and functional reliability.

The external spraying of the 103 machines is basically the same as the previous 101 and 102 machines, and the “C 919” sign is particularly conspicuous.

The third aircraft tested today, although the painting is consistent with the first two C919, the shape is not easy to distinguish, but its internal structure has been adjusted based on the results of the previous flight test, will be used applying for a type certificate to the Civil Aviation Administration of China (ie, accepting official tests to prove that the C919 is qualified), so it is the first “real C919.”
