国内定期旅客便の運航効率の客観分析

Abstract

Flight efficiency of passenger aircraft scheduled flights is analyzed by using surveillance radar data. Flight parameters which are necessary to evaluate the flight efficiency such as air speed and fuel flow are estimated from position data of the radar data by combining weather prediction data and aircraft performance models. Trajectory optimization is applied to the estimated flights in order to evaluate the flight efficiency by comparing with the minimized fuel and flight time. Arrival flights to Tokyo International Airport are analyzed to demonstrate the approach.
