Overview of Application in Data Mining Techniques to QAR Data Ansys

To ensure flight safety, the Civil Aviation Administration of China (CAAC) requires commercial aircraft to be fitted with a Quick Access Recorder (QAR), which continuously records the aircraft's raw flight data and captures thousands of flight parameters. Currently there is limited awareness and application of QAR data. With the continuous development of data analysis technology, data mining methods have been applied to QAR data processing, providing strong support and guarantee for aviation safety. This paper introduces the basic theory of data mining, reviews the applications of data mining in civil aviation operational safety, flight status assessment and identification, and general aviation respectively based on the clustering results of the literature in the past 12 years, and finally summarises the current problems faced by QAR data mining and the future development direction.
