This paper put forward a practical method of flight parameter trend analysis,which effec-tively made up for the lack of fault trend prediction in the traditional method of helicopter flight pa-rameter interpretation.It introduced in detail how to use the trend analysis method to analyze the trend changes of 18 kinds of key parameters that best represent the helicopter safety state,and deter-mined the corresponding helicopter maintenance ideas according to the trend changes,and made an empirical application,which strongly proved that the flight parameter trend analysis method could play an important role in helicopter daily maintenance.
