The Flight Test for PBN in Yining Airport Successful

In October, a Boeing 737-700 aircraft of special significance landed steadily at Yining Airport, which marked the successful end of the performance based navigation (PBN) test in Yining Airport. Yining Airport lies in the northern suburbs of Yining City. The Mountain Ranges of Tian Shan Mountains stand close to the north and east sides of the Yining Airport, which makes the flight conditions of the airport poor. This flight test was organized by the CAAC’s Xinjiang Regional Administration and conducted by China Southern Airlines’ Xinjiang Company, with the CAAC’s Xinjiang ATMB and the Xinjiang Airport Group Co., Ltd. present to offer security. In the flight process that had lasted nearly three hours, the flight test team and inspectors carried out the systematic inspection and verification of the PBN approach and departure procedures, the perpendicular navigation ability of vapor-pressure type, the control and support capabilities and the integrity and accuracy of the on-board navigation database. The PBN is one of the core technologies in Mainland China’s new generation of air transportation system. It plays an active role in China civil aviation’s continued safety, enhancing the quality of flight, increasing aircraft flow in airspace, reducing the amount of ground facilities and energy-saving and emissions-reduction.
