With the gradual maturity of aviation technology, the number of civil aircraft development projects has increased. In order to carry out the development projects with high quality and efficiency, it is necessary to apply the risk management mechanism to the civil aircraft development projects. Based on this, this paper summarizes the specific application of risk management in the development of civil aircraft development projects. During the development of civil aircraft development projects, it is extremely vulnerable to environmental factors and control factors, resulting in an increase in engineering uncertainties, project delays and abnormal increase in costs and other problems. Applying risk management methods to civil aircraft development projects can not only find out the risk problems existing during the development of civil aircraft development projects in time, but also continuously improve and optimize the management mechanism of civil aircraft development projects based on these risk problems to ensure that the development level of civil aircraft development projects can better meet the development needs of China's aviation industry. Firstly, this paper applies the project risk management technology method to count the risk cases of aircraft development projects, analyze the risk factors of aircraft development projects, and combine the system engineering idea to build the risk evaluation index table of aircraft development projects for the first time, and comprehensively apply the WBS and FMEA of aircraft development projects analysis and network planning technology and other technical methods are used to carry out the schedule risk analysis of the aircraft development project scheme confirmation stage, and obtain the risk ranking in line with the actual situation. This risk analysis method can also be applied to the risk analysis of cost and performance quality. Based on the analysis of the risk cases of the aircraft development project, the risk control process of the aircraft development project is designed and the risk warning signal is set in it, which not only allows the project managers and decision makers to fully grasp the project risk situation, but also facilitates the project management organization to control or avoid the project risk in a timely manner. 

Risk of civil aircraft development project based on big data analysis technology

In order to establish the basic data architecture for aircraft in-service configuration management, ensuring efficient implementation of it, the characteristics of configuration change caused by various maintenance and support operation during the service phase of large civil aircraft were analyzed. On this basis, formal classification of in-service aircraft configuration data was carried out. Based on the product structure tree, the architecture of the aircraft configuration data was constructed. The in-service aircraft configuration data schema was defined. By introducing the idea of Skyline query, the configuration change information filtering method was designed and implemented. Finally, method validation was performed by the maintenance and support data of an airline company. The results show that, the automatic extraction of configuration change information is realized effectively, ensuring the full integration of the in-service aircraft configuration data schema and production and maintenance information management, and ensuring the real-time and consistency of in-service aircraft configuration data management.
