flying experience, increase flying experience.”The three flight crew members of the plane are the captain, the co-pilot and the flight trainee.”Eastern airlines customer committee general manager shangguan Snow min said.Sun said the three pilots’ licenses and health certificates were valid, and they were in good health and had complete flight experience, which met the requirements of the bureau.The total flight time of the three was 6,709 hours, 31,769 hours and 556 hours respectively.Did the plane ever hang out the 7500 emergency code?Mr Liu said communications had been normal before the flight disappeared.In other words, the crew didn’t hang out any emergency codes.It is understood that the civil aviation industry from 0000 to 7777 numbers, choose 4096 numbers, to represent the different situations encountered in the flight.For example, 7,500 means “hijacked” and 7,600 means “communication failure”.MAO Yanfeng, director of the civil Aviation Accident investigation Center, said that according to the records of the air-to-ground communication between the crew and the air traffic control unit, the plane had maintained normal communication with the air traffic control unit
