In this study, many optimum route simulations for B747-400 flying New York-Tokyo route and Tokyo-London route were performed to evaluate the advantage of flexible routes passing not only over the ocean but also over the continent. The forward dynamic programming was used to determine the flexible routes between above two cities. From the results of simulations, it was found that compared with the present daily routes, the following fuel saving was achieved on the average on the flexible routes : New York-Tokyo : 3.9% (westbound) 2.0% (eastbound) Tokyo-London : 8.5% (westbound) 5.6% (eastbound). At the same time, approximately the same amount of time saving was achieved on the above flexible routes. It was also verified by the simulations that on the westbound flights from New York to Tokyo, the newly established route across the Russian Far East for the FANS aircrafts was much more economical than the present NOPAC route.
