Research on aircraft taxi trajectory correction during landing stage based on S-G filter algorithm
Analyzing the operational trajectory of aircraft during landing is an important means to objectively evaluate the tech-nical level of pilots and the operational quality of airlines,and is of great significance in ensuring the safe and efficient operation of aircraft.Through dot analysis of the longitude and latitude parameters in QAR data in map software,it was found that the trajectory of the aircraft during deceleration and taxiing on the runway showed significant twists,dislocations,and deviations.This article uses the S-G filtering algorithm to construct a trajectory correction model for the aircraft landing phase,and performs trajectory cor-rection processing.The results indicate that the S-G filtering algorithm can effectively correct the original trajectory by modifying the model.
