Method and device for determining the optimal flight trajectory of an airplane

摘要

Devices (5) are available for evaluation of the cost of the selected portions of the course. Also available are devices (6) for determining the possible courses and their costs. Finally, devices (7) are incorporated which compare the costs in order to retain the courses which evidence the lowest cost and for determination of the sought-after optimal course. These final devices (7) determine the optimal positions of the points of change of flight level between first and second positions. The first position corresponds to the end position and the second position corresponds to the initial position of the flight course. In the prediction process, specific characteristics of the aircraft are used, together with meteorological information.
