Abstract

In order to analyze impacts of air traffic control risks on aircraft airworthiness flight test accidents, firstly, corresponding flight profile was drawn according to aircraft flight test subjects. Secondly, based on the flight profile of test activities, support process of the control unit was analyzed, and risk factors on test activities were extracted. Then, evolution process of accidents were analyzed by utilizing fault tree analysis(FTA), and events and logical relationship were mapped to BN. Finally, conditional probability tables were determined on the basis of unsafe event classification results of civil aviation and risk assessment conclusion of flight activities by aircraft manufacturers, and posterior probability was calculated based on variable elimination method to derive main causes of accidents. The results show that when unsafe events or potential accidents occur in flight test activities, management factors are the key causes in ATC support progress. Flight test mission, airspace environment and controllers' work error are also the major risk sources. © 2019 China Safety Science Journal
