Description

<p>The research trends in recent years, large and various amount of digital data set called big data are focused on. For the purpose of promoting research in air traffic management, flight track data of Air Traffic Control have been provided as CARATS Open Data by Ministry of Land, Infrastructure, Transport and Tourism. The CARATS Open Data which is newly opened to the public in August 2016 includes Haneda terminal radar control data. In order to increase the Haneda airport departure and arrival slot, such technology that increases the prediction accuracy of ground speed of Haneda airport approach trajectory considered to contribute. We can expect new findings by analyzing the trajectory data, though the deterioration of accuracy of ground speed is pointed out by calculating the speed from the difference of position data and time. In this paper, ground speed in Haneda airport approach trajectory is investigated using CARATS Open Data, and the variation of approach speed by aircraft type is discussed.</p>
