Abstract
In order to achieve an efficient and orderly air traffic flow in the future air traffic systems, realization of Trajectory-based Operation (TBO) is expected. In TBO, all aircrafts are managed by ATM (Air Traffic Management) operation along 4-DT (4-Dimensional Trajectory) which introduces time-based management in all phases of flight. This operation enables us to address an increased air traffic capacity by attaining trajectories. To introduce TBO, researches on aircraft trajectory prediction considering meteorological influences are necessary. As a preliminary study, we simulate the flight trajectory using BADA in ISA (International Standard Atmosphere) condition and non-ISA condition in which temperature differential for ISA is considered. Analysis of the data that obtained by SSR mode-S system is also performed. This paper reports the preliminary study on the indeterminacy of trajectory prediction by meteorological influences.
