Risk Assessment on the Transition Program for Air Traffic Control Automation System Upgrade

Abstract

We analyzed the safety risks of the transition program for Air Traffic Control (ATC) automation system upgrade by using the event tree analysis method in this paper. We decomposed the occurrence progress of the three transition phase and built the event trees corresponding to the three stages, and then we determined the probability of success of each factor and calculated probability of success of the air traffic control automation system upgrade transition. In the conclusion, we illustrate the transition program safety risk according to the results.
