The lack of entry standards and exit mechanisms is one of the main reasons for the widespread criti? cism of China's civil aviation passenger blacklist. The degree of harm and recurrence probability of misconduct and the subjective viciousness of passengers should be used as the main criteria for whether civil aviation passen? gers are blacklisted. For the measurement of the degree of harm of misconduct, the following three aspects can be considered: first, the severity of the misconduct itself, second, whether the misconduct has caused serious consequences, and third, the possible consequences of the misconduct. For the judgment of the recurrence prob? ability of misconduct, the main consideration is whether the behavior is objectively“repeatable”and the prob? ability of recurrence. For the determination of the subjective viciousness of passengers with misconduct, it is nec? essary to judge whether the behavior is caused by the passenger's lack of aviation knowledge, or because the pas? senger has not yet developed good travel habits, or whether it is deliberately done by the passenger. In terms of legislation, detailed provisions should be made on the entry standards for the civil aviation passenger blacklist, unifying and categorizing passenger misconduct, and clarifying the entry mechanism and exit mechanism of the civil aviation passenger blacklist.
