To solve the problem caused by different layout of fuel systems of A320 series, the disposal method of common malfunctions of A320 series was put forward. Firstly, the layout, fuel supply components and logic in fuel supply system of A320 series aircraft were systematically summarized. Secondly, the common malfunctions that may affect the operations were analyzed. According to different layouts, it is pointed out that the two components that have the greatest impact on operations are the central fuel pumps and transfer valves. Thirdly, the disposal methods of dispatchers under different fault conditions were put forward. Finally, an example was given to illustrate the aircraft in the dispatch stage, take-off stage, no fuel stage in the central tank and the consumption stage of the fuel in the central tank. The results show that the proposed method is systematic and comprehensive, and can effectively guide the dispatch and disposal to deal with common malfunctions of the central fuel pump or transfer valve.
