Abstract : In light of the increasing number of overflights through the Fukuoka flight information region (FIR) in recent years, we attempt to analyse the effects of overflights and propose a solution to associated problems. In this study, Collaborative Actions for Renovation of Air Traffic Systems (CARATS) Open Data files are used to analyse the effects of overflights. The CARATS Open Data which include the time histories and position data of commercial flights within the Fukuoka FIR, are obtained by the Japan Civil Aviation Bureau (JCAB) from radar tracks. Examination of the data shows that overflights sometimes occupy their optimal altitude during cruise, preventing airliners on international flight paths from Japan from climbing to required altitudes and decreasing their cruise altitudes. Data extracted from crowded situations are analysed in order to propose a solution to the conflict problem.
