MoC6 airworthiness compliance verification flight test is an important and necessary condition for civil aircraft certification. Flight Data Recorder is an on-board equipment and one of the contents of its MoC6 test is to download the data recorded by flight data recorder (FDR) after the flight test, and compare it with the data recorded by flight test instrument(FTI) to determine whether the recorded data in FDR is accurate. This article in how to tell whether the data recorded in FDR is correct by means of Minkowski distance. By the way, the p parameter and the threshold value for Minkowski distance is acquired via machine learning. In this paper, the inconsistent parameters recorded by FDR and FTI were identified, achieving a recall rate of 100%.
