According to the flight data increasing rapidly and the feature of query and analysis,a distributed data storage scheme using database cluster to store flight data is proposed. A flight data partition method for data fragmentation is also put forward based on the data feature of the plane failure analysis. The experiment result shows that the scheme reduces the query time. In conclusion,using database cluster to store flight data supports the parallel access to the flight data,expands data storage easily;data partition method based on fail-ure analysis feature improves the fight data query efficiency when doing failure analysis.
