This paper takes the analytic hierarchy process as the basic method to establish the air traffic control tower safety risk factor set. In combination with the gray theory and fuzzy mathematics principle to determine the gray fuzzy evaluation conclusion set and the index layer factor score value matrix, we calculate the gray evaluation coefficient and build the evaluation weight matrix to evaluate the control operation risk of air traffic control towers. Finally, the case verification is carried out, and the risk assessment value of the air traffic control tower used in the case is calculated as 5.6325, which belongs to the “general risk” level. The evaluation method adopted in this paper can provide reasonable suggestions for operational risk management of air traffic control towers.
