Air traffic control safety has an important influence on civil aviation transportation safety. Based on identified operation risk factors of air traffic control,the multi-index system of air traffic control safety evaluation was constructed and the quantitive rule of the index was ascertained. The synthetical model of safety comprehensive evaluation for air traffic control was established in the employ of principal element analysis method. Analyzed an example of air traffic control safety comprehensive evaluation,both factors of the index system affected the operation of air traffic control safety were found out,namely the deregulation and the competence of controller. The availability of equipment was hidden trouble of air traffic control operation. Finally,the safety of 4 units of air traffic control was evaluated in the light of the synthetical model of safety comprehensive evaluation for air traffic control. The results show that the method is useful for making the safety countermeasures of air traffic control and improving its safety.
