Abstract(in English) | RNAV road map was made by Civil Aviation Bureau for effective utilization of area navigation (RNAV). Following the road map, RNAV routes have been implemented in Japan. Annex 11 to the Convention on International Civil Aviation describes that any significant safety-related changes to the ATC system shall only be effected after a safety assessment has demonstrated that an acceptable level of safety will be met. For implementation of RNAV parallel route, the estimation of the safe minimum route separation of RNAV routes was required. The distribution of cross-track deviations of the aircraft which flew on the RNAV arrival route was estimated. Then a probability distribution model of it was found. The lateral overlay probability was estimated using the empirical distribution and its deformation. Collision risk was estimated by collision risk formula using the estimate of lateral overlap probability together with other given parameters. As a result, in the case that the population of aircraft with poor navigation performance, which barely meets 95% containment requirement, is assumed to be 10 percent, estimates of minimum route separation are 8NM for RNAV1 routes and 32NM for RNAV5 routes, respectively. |
