Longitudinal collision risk for oceanic air routes in ADS environments

摘要

It is expected that the separation minima applied for aircraft flying oceanic air routes will be reduced after the introduction of Automatic Dependent Surveillance (ADS) systems. A safety study using a collision risk model is required for assessing the feasibility of a reduced longitudinal separation. The longitudinal collision risk for a hypothetical route system is estimated under several assumptions. Modeling the distributions of associated collision risk model parameters and estimation of those by a computer simulation were conducted. This paper describes the method and results of the analyses briefly.
