飛航事故發生後，尋找及解讀飛航紀錄器（Flight Recorder）是首要工作，根據其記錄資料可獲得事故發生過程中飛航組員的通話、與客艙組員及航管人員的通話、駕駛艙內的警告，航空器的各種狀態參數。對於未安裝飛航紀錄器及紀錄參數甚少、維修問題致無紀錄或紀錄錯誤，或飛航紀錄器未斷電致資料遭覆蓋等情況下，航電設備中的非揮發性記憶體（Non-Volatile Memory, NVM）就成為事故調查的主要證據來源。本研究是為持續提升飛航事故調查的工程能量，探討NVM晶片安裝情形、建立NVM晶片處理程序，更妥善地應用飛航紀錄器及NVM資料於事故調查中。此外，彙整作者實際工作經驗及國內外事故案例，探討NVM晶片的紀錄內容、資料分析及應用情況。

When an aviation occurrence happens, to locate and readout the flight recorders, it is a priority task. According to the recording data, it can discover the communications between flightcrew, cabin crew, and air traffic controller, associated cockpit warnings, and a variety of state parameters of the aircraft. For the aircraft without flight recorders, limited recording parameter, maintenance related recorder malfunction, or flight data overwritten. Onboard avionic equipment with Non-Volatile Memory (NVM) has become the main source of evidence during occurrence investigation. In order to continue improving technical capability of investigation, this paper survey the NVM chipset types and installation the national in aircraft, and formulates the NVM handling procedures, to be better applying the flight data and NVM data. In addition, the study extracts that author's realistic experience, national and international aviation occurrences, to discuss recording information of the NVM, data analysis and application.
