10: 34, the second passenger plane C9 19, piloted by captain Wu Xin and the test pilot, took off from the fourth runway of Pudong International Airport, with observers Zou and flight test engineers David and Liu Lisu on board.
The plane cruised in the prescribed airspace at an altitude of 4500m 1 hour15min, and returned to land safely at 12: 34 after completing the scheduled flight test.
This flight initially examined the take-off and landing performance of the aircraft and the working conditions of the main systems and equipment. During the flight, the state of the aircraft flap, landing gear system, navigation and communication system and the acceleration and deceleration characteristics were checked.
C9 19 large passenger plane is a 150-seat single-channel trunk aircraft independently developed by China according to the airworthiness standards in line with international standards. The feasibility study of the project was completed at the end of 2008, and 20 1 1 was finally assembled in Shanghai in 2005. Among them, the first C9 19 aircraft completed its "first flight" at Pudong International Airport on May 5, 201July, and was transferred to Yanliang, Shaanxi on June 010/0.
Mao Wei, head of the China Commercial Aircraft Corporation's Civil Aircraft Test Center 102 aircraft group, said that the second C9 19 passenger plane had carried out low-speed taxiing test and medium-speed taxiing test successively since it entered the flight test stage on June 23, reaching the condition of "first flight". Compared with the "first flight" of the first aircraft, today's flight altitude, flight speed and mission points have been significantly improved.
Wang Wei, chief engineer of China Commercial Aircraft Flight Test Center, introduced that according to the C9 19 large passenger aircraft project plan, a total of six flight test aircraft were put into flight test and two aircraft were tested on the ground. Six flight test aircraft need to complete more than 1000 compliance verification tests, and two ground test aircraft need to carry out system integration tests, static tests of the whole aircraft and fatigue tests.
Wuyue, general manager of C9 19 large passenger aircraft project of China Commercial Aircraft Corporation, said that in the next few years, Comac China will launch intensive test flights at national airports, with Dongying in Shandong and Yanliang in Shaanxi as the main battlefields, in conjunction with aviation industry corporation of china and other institutions.
This will be the first time for China to verify the airworthiness of the 150 class trunk aircraft, and the C9 19 large passenger aircraft will also be tested at the highest level in China aviation industry.
