METHOD AND DEVICE TO ESTIMATE COSTS OF DEVIATION IN A FLIGHT TRAJECTORY

摘要

A method and device for determining and presenting cost impacts generated by lateral route deviations of an aircraft. The device includes a computation unit for determining different flight trajectories, called alternative trajectories, each of which is offset laterally in the horizontal plane relative to a reference trajectory, notably the current trajectory of the aircraft, and a computation unit configured to compute, for each of the alternative trajectories, an associated overall cost which provides an indication of the cost generated by a flight of the aircraft along this alternative trajectory, the device also includes a display unit configured to present, on a navigation screen, indication elements which provide indications concerning the position and the associated overall cost for at least some of the alternative trajectories.

1. A method for determining information regarding costs in flying an aircraft along an alternative flight trajectory, the method comprising:
a) automatically determining alternative flight trajectories, and determining for each of the alternative flight trajectories a horizontal offset between the alternative flight trajectory and the reference flight trajectory; b) automatically computing for each of the alternative flight trajectories, an associated cost associated with the alternative flight trajectory indicating a cost of flying the aircraft along the alternative flight trajectory; and c) presenting on at least one navigation screen of the aircraft, one or more graphical or alphanumeric indication elements that convey the position and the overall cost for one or more of the alternative flight trajectories.
