Recently, reliability requirements, e.g. accuracy and integrity have been used for describing the required navigation performance (RNP) necessary for aircraft operation in a specified airspace. Collision risk models have been used for the safety assessment of separation minima applied to the RNP certified aircraft. Lateral overlap probability is an important parameter of the models and depends on the lateral path-keeping error distribution of aircraft. In the previous study, a mixture of Gaussian core and double exponential (DE) tail distribution has been proposed as a model of the distribution. This paper deals with the characteristics of the lateral overlap probability based on an extended DE tail model for lateral path-keeping error distribution.
