Abstract (in Japanese) (See Japanese page) 
(in English) Trajectory prediction technique for commercial aircraft is an important element of air traffic control. Since the trajectory prediction is calculated based on an aircraft model, the accuracy of the aircraft model has a significant impact on the trajectory prediction accuracy. In a terminal airspace, which is around an airport, each airspace has an unique operation method; hence, the aircraft model, especially the speed profile, differs in each terminal airspace. In this study, a speed profile suitable for a specific terminal airspace is developed by performing regression on actual flight data. Since the speed profile of an aircraft is nonlinear and the appropriate model is not clear, we use Gaussian process regression, which is a nonparametric regression method. The obtained speed profile is evaluated by comparing it with a widely used model of a passenger aircraft. By applying the speed profile to the trajectory prediction, the effect of the improvement of the speed profile on the accuracy of the trajectory prediction will be evaluated.
