Abstract�� In order to predict civil aviation safety, the range prediction model was developed by using grey range prediction method, which suited for the character of less and uncertain of the safety assessment result data. The results of civil aviation safety indices were shown. According to these results, the civil aviation safety level was analyzed, which showed the function and usage of this safety assessment indices system. To demonstrate the validity of grey range prediction method, the grey prediction range model of civil aviation safety assessment was tested by actual data of China civil aviation composite safety index. By using this model, the prediction range of China civil aviation composite safety index for next year was given.
