First Claim
Patent Images
1. A processor-performed method of aircraft flight planning, the method comprising:
- identifying a decision point along a route of the aircraft;
using the decision point and an anticipated range of the aircraft at the decision point to define an elliptical area substantially forward of the decision point and substantially along the route; and
based on location of one or more landing facilities relative to the defined elliptical area, selecting one or more of the facilities as one or more alternative destinations.

Abstract
A processor-performed method of aircraft flight planning. A decision point is identified along a route of the aircraft. The decision point and an anticipated range of the aircraft at the decision point are used to define an elliptical area substantially forward of the decision point and substantially along the route. Based on location of one or more landing facilities relative to the defined elliptical area, one or more of the facilities are selected as one or more alternative destinations.

8. An aircraft flight planning system comprising a processor and memory configured to:
-
identify a decision point along a route of the aircraft; use the decision point and an anticipated range of the aircraft at the decision point to define an elliptical area substantially forward of the decision point and substantially along the route; and based on locations of a plurality of landing facilities relative to the defined elliptical area, select one or more of the landing facilities as one or more alternative destinations. - View Dependent Claims (9, 10, 11, 12, 13)

14. A processor-performed method of aircraft flight planning, the method comprising:
-
identifying one or more decision points along a route of the aircraft; and for each of the one or more decision points; defining an ellipse forward of the decision point that represents an area substantially along the route and that includes the decision point as a vertex; prioritizing a plurality of alternative destinations within the represented area, the prioritizing performed at least in part based on distance relative to the decision point; and based on the prioritizing, associating one or more alternative destinations with the decision point. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
