In recent years, aircraft flight accidents frequently occur, and serious threats are brought to the safety of flight groups and passengers. After a flight accident occurs, a government usually takes the lead to search for a black box, and determines the cause of the accident and a person in charge according to aircraft flight data and cockpit recording data stored in the black box. The effective premise of the method is that a black box of the airplane can be found. However, most flight accidents occur at sea, and the black box is difficult to find and salvage. For flight accidents for which no black box is found, an effective method is not available for accident reason judgment and responsibility division. To avoid this, ACARS has been proposed by the relevant personnel. The flight data is transmitted periodically to a ground station. However, this approach only allows for flight data storage and does not allow for storage of control commands and safety issues. For human-induced flight accidents, the division of responsibility between pilots and ground commanders becomes particularly important. Under the existing mechanism, the ground station has no effective way to safely store the control instruction issued by the ground commander. Therefore, after the aircraft accident happens, the ground commander who issues the wrong control instruction can repudiate the personal behavior, and further serious influence is brought to the division and responsibility pursuit of the aircraft accident responsibility.
