Lateral overlap probability is a critical parameter for estimating the collision risk of aircraft pairs flying on parallel tracks. This is usually estimated from the distribution models of lateral path-keeping errors. The author has proposed several models for lateral path-keeping error distributions of RNP-RNAV aircraft. In those models the probability density functions (pdf) of the core and tail regions are modeled separately and resulted in discontinuity at a point. In order to resolve this unnaturalness a mixed pdf model consisting of the generalized Laplace (GL) core and double exponential (DE) tail is proposed in this paper. Based on this model, the characteristics of the distribution are discussed in relation to the maximum lateral overlap probability.
