Abstract:

The homology of QAR data and ACARS report data has been analyzed, as well as the structure and extraction logic of the engine stable frame report. An extracting method of engine stable frame report which meet the triggering conditions from QAR data is proposed. With the help of this method, not only the vast amount of raw monitoring QAR data can be fully tapped, but also a simulated ACARS report is obtained, which can be used in emergency management of airlines, assisting researches in condition monitoring and fault diagnosis of aircraft and engine. It can also be used in universities and scientific research units in teaching and researching.Computational analysis of both the actual ACARS reports and the extracted data of a B747- 400 airplane verifies the reliability and great prospects in application of this method.

Key words: QAR data, ACARS report, homology analysis, extraction logic, reliability testing
