Abstract(in English)	This paper considers the meaning of the average relative speed in order to investigate the limitation in applicability of a lingitudinal collision risk model. In the longitudinal collision risk model, the average relative longitudinal speed is a parameter closely related to the relative velocity distribution and the initial longitudinal separation of aircraft pair. In order to investigate the relationship between the reporting time period and the average relative longitudinal speed, analyses were conducted using simple distribution models under several assumptions. The results identify the feature of average relative longitudinal speed. This paper describes the method and results of analyses
