Abstract：According to the features of air traffic control ( ATC ) safety risk factors , the events of air-ground communication failure in the airport are chosen as the sample data .Taking the advantage of cross-spectrum analysis in the aspect of time series , the contribution , lead-lag relationship and correlation of ATC safety risk factors are analyzed .The results show that the influence of process deviation to ATC unsafe events is 49%.The influence of equipment failures and external interference , respectively 18% and 4.8%, has synchronization effect .Therefore, aiming at the decisions of communication unsafe events for pre-control strategies, process management of communication program execution should be strengthened , pertinent resources be allocated reasonably , and the shift arrangement plan optimized so as to prevent from communication unsafe events and accidents .
