According to the ground-to-air communication records between the crew and the air traffic control unit, the crew and the air traffic control unit maintained normal communication from the time the aircraft took off from Kunming until it suddenly dropped in altitude on the route.

The final emergency response is a responsible behavior for passengers, and everything must be subject to the conclusion of the investigation team. China Eastern Airlines will strictly comply with civil aviation safety management regulations and carry out relevant work in an orderly manner. At present, China Eastern Airlines has sufficient transportation capacity, and its flights will not be affected by the grounding of some aircraft.
