There are few effective methods for remote monitoring of instrument landing systems. This study was based on the QAR data of CAAC, it proposed an analysis method for the navigation signal of Instrument landing system. With the time, altitude, longitude, latitude, descent rate, the deviation of localizer and the deviation of glide path from the QAR data, the flight trajectories and DDM curves of localizer and glide path were plotted. Finally, abnormal event of instrument landing system in Xi'an Airport was found with the method by using the QAR data of A320 aircraft.
