In view of the current situation that Quick Access Recorder(QAR)'s analysis data is large and professional and that existing systems are difficult to meet the requirements, through working mode optimization, auxiliary tools, data analysis and other means, a set of efficient and low-cost QAR data batch processing and application method is formed. Combined with safety, energy conservation and other management objectives, this paper deeply explores and studies data, outputs corresponding analysis results, and puts forward business development suggestions, in order to achieve the goal of improving flight quality and reducing operational risks and costs.
