Estimating optimal route spacing between parallel arrival routes for Area Navigation (RNAV) operation is required. It's necessary to estimate lateral overlap probability, which is one of the_ most important parameters of collision risk model, for estimating the route spacing. For estimating the lateral overlap probability, a distribution of cross track deviations was estimated using the radar data of Kagoshima Airport, flight plan data and flight strips.The results obtained are as follows. (1) The standard deviation of the observed cross track deviations of 2,298 flights is 0.077NM. (2) The best fitted model for the empirical cross track deviations is Normal(Gaussian)-normal (N-N) model. The fitted parameters are α=0.117, σ_1=0.0673NM and σ_2=0.129NM.
