The present invention relates to a method and system for predicting an aircraft trajectory through monitoring of real-time track data, which can monitor track data providing location and state information of an aircraft in real time, and which can incorporate the track data into prediction of a flight trajectory of the aircraft, thereby improving accuracy of a result of the prediction of the flight trajectory. The present invention discloses the method for predicting an aircraft trajectory, the method comprising the steps of: generating a planned flight trajectory based on a flight plan, and generating a predicted flight trajectory based on the flight plan and track data; calculating a trajectory location error of an aircraft for the predicted flight trajectory based on the track data collected in real time; determining whether to generate a newly predicted flight trajectory by comparing a trajectory deviation criterion, set based on the predicted flight trajectory, with the trajectory location error; and updating the existing predicted flight trajectory by generating the newly predicted flight trajectory or maintaining the existing predicted flight trajectory depending on a result of the determination. The present invention also discloses the system for predicting an aircraft trajectory by using the method.
