On November 20th, a large domestic aircraft C919(B001F) successfully made a test flight on the runway of Taizhou International Airport in Yangzhou, which was a step further from the official flight. It is reported that the flight C919 was a verification test flight before the domestic large aircraft was officially delivered to the world's first user (China Eastern Airlines). In order to ensure the training flight, nearly 100 support personnel were dispatched by the ground support teams such as China Commercial Aircraft Flight Test Center and Customer Service Center, and the inspectors of the East China Regional Administration of Civil Aviation and the first pilots of China Eastern Airlines C919 also arrived at Yangtai Airport at the first time. Not long ago, C919 launched its first flight test at Chengdu Shuangliu Airport.

At present, Comac China has awarded type certificate for C919 aircraft, and all kinds of tests have been basically completed. Next month, that is, December, the first C919 aircraft will be officially delivered to China Eastern Airlines, and the commercialization era of domestic large aircraft will be started at the beginning of next year.

Speaking of commercialization, the C919 aircraft took a large number of orders before it was put into operation. At the Zhuhai Air Show held not long ago, Comac China signed a confirmation order agreement with a number of aircraft leasing companies for a total of 330 domestic aircraft, including 300 C919 aircraft.
