BEIJING, May 13 (Xinhua) -- Beijing Daxing International Airport completed its first test flight of passenger planes as four aircraft landed safely on the runway Monday morning.

China Southern Airlines, China Eastern Airlines, Air China and Xiamen Airlines sent their flagship models A380, A350-900, B747-8 and B787-9, respectively, for the test.

"The test shows that the new airport has now turned its focus from infrastructure construction to operation preparations," said Wan Xiangdong, chief pilot of Civil Aviation Administration of China.

The test followed the airport's first flight of verification planes on Jan. 22 this year. The airport is scheduled to take low-visibility flight test in August and go into operation before Sept. 30.
