RÉSUMÉ

The minimum-fuel aircraft cruise optimization problem under real wind conditions is considered. An analytical solution based on Pontryagin's maximum principle for the linearized wind model is obtained. A trajectory optimization algorithm based on the continuation method for arbitrary spatial wind distribution is developed. It is shown that under real atmospheric conditions the optimal solutions allow obtaining considerable fuel savings even for closed routes. An example of applying the developed algorithm to a long-haul airplane on specific routes is given. Attention is paid to the effect of the wind factor on the choice of the optimal aircraft configuration and route logistics.
