Simulation Analysis of the Conflicts among the International Departure Flights from Asian Region over Pacific Oceanic Airspace

Abstract

The purpose of this study is to examine the actual and future situation of the operational conflicts between international departure flights from Japan and overflights at the pacific oceanic airspace. The Monte Carlo simulation model based on the actual operational characteristics of the flights from Asian region to US is developed to analyze the operational conflicts at the entry fixes to the pacific oceanic airspace. From the simulation analysis where the several traffic condition scenarios are assumed, the probability and the degree of the operational conflicts at the target airspace can be obtained. The major evaluation indexes are the flight level, the delay of the flights and environmental impacts (Fuel and CO2 emission). The results from this study can be one of the important materials to design more efficient and fair air traffic control and management in the oceanic airspace in the future.
