The playback of flights' surveillance information plays an import role when flights encounter special circumstances, such as accidents. It can help analyze when, where and why the special circumstances happened intuitively. Different from traditional air traffic control automation system, we propose a playback system based on double-buffers method. A playing buffer and a fetching buffer is created, one is for storing the surveillance information that will be play back and the other one is used for storing the surveillance information fetched from the database. Thus, data fetching and data playback can be done concurrently, to play back the flights' surveillance information continuously. What's more a reliable UDP is proposed to improve the reliability of the data communication of the playback system.
