The enroute level cruise started 7 miles south west of Qingshuihe in Qinghai Sheng, China, and lasted for 120 minutes, covering a distance of 1,120 nautical miles. The aircraft then began its enroute descent, starting 18 miles east of ZSNJ Nanjing Lukou International Airport in Nanjing, China. The descent took 18 minutes, during which the aircraft descended from 40,710 feet above sea level to 2,437 feet above sea level, a decrease of 38,273 feet.

The aircraft then began its final approach to runway 18 at ZCHA Shanghai Dachang Air Base, heading 168.0 degrees at 3 nautical miles and 1,779 feet above ground level. The landing was made on runway 18, which had a length of 3,046 meters. The threshold speed was 126 knots, and the touchdown distance was good at 233 meters. The touchdown speed was 116 knots, and the touchdown rate was firm at -333 feet per minute.

The runway touchdown position was slightly misaligned by 5.7 meters from the centerline, but the runway rollout alignment was very good. The local weather conditions at the time of landing were characterized by a temperature of 15 degrees Celsius, with a wind speed of 8 knots at a direction of 335 degrees. This resulted in a crosswind of 2 knots and a tailwind of 8 knots. The total landing distance was 802 meters, which was 26% of the runway length.
