System and method to compute optimum cruise level by considering atmospheric conditions

Abstract:

A computer-implemented method in an aircraft for identifying a flight plan modification that has a favorable impact from jet streams is provided. The method includes: retrieving an entered flight plan for the aircraft; retrieving available jet stream data identifying one or more jet streams in proximity to a proposed flight path from the entered flight plan, wherein the jet stream data includes jet stream vector, altitude, width, and thickness data; projecting the jet stream data around the proposed flight path as points of interest around the proposed flight path; identifying a flight plan modification that has the most favorable impact from jet streams at the points of interest; and displaying the identified flight plan modification on a user interface.
