Methods and systems facilitating holding for an unavailable destination
First Claim
1. A system comprising:
- a display device having a map associated with a vehicle displayed thereon;
an input device to obtain one or more time constraints for an intended destination for the vehicle, the one or more time constraints including an estimated availability time and a maximum travel time from the intended destination; and
a processing system coupled to the display device and the input device to;
identify, from within a region encompassing a current position of the vehicle, the intended destination, and a conditional diversion destination, a plurality of points within the maximum travel time of the intended destination;
identify, from among the plurality of points, an intermediate point having a minimum travel time to the conditional diversion destination;
construct an interim route from the current position of the vehicle to the intended destination that deviates towards the conditional diversion destination and traverses the intermediate point based at least in part on the one or more time constraints for the intended destination by;
determining, for each potential route combination of a plurality of potential route combinations from the current position of the vehicle to the intended destination via the intermediate point, a respective fuel consumption and a respective estimated arrival time associated with the respective combination;
determining, for each potential route combination, a respective first difference between a respective fuel consumption associated with the respective route combination and a minimum fuel consumption among the plurality of potential route combinations;
determining, for each potential route combination, a respective second difference between a respective estimated arrival time associated with the respective route combination and the estimated availability time;
determining, for each potential route combination, a respective route score comprising a weighted sum of the respective first difference and the respective second difference; and
identifying the interim route as the potential route combination having a lowest respective route score from among the plurality of potential route combinations; and
display a graphical representation of the interim route on the map.

Abstract
Methods and systems are provided for generating an interim route that facilitates navigating a vehicle to an intended destination. One exemplary method facilitating an aircraft landing at an intended destination involves obtaining a current position of the aircraft, obtaining one or more time constraints for the intended destination, determining an interim route from the current aircraft position to the intended destination that veers towards a conditional diversion destination based at least in part on the one or more time constraints for the intended destination, and providing indication of the interim route to an aircraft operator, for example, by displaying a graphical representation of the interim route on a navigational map on a display device.

2. A method of facilitating an aircraft landing at an intended destination, the method comprising:
-
obtaining a current position of the aircraft; obtaining one or more time constraints for the intended destination, the one or more time constraints comprising an estimated availability time associated with the intended destination and an allowable flight time from the intended destination; determining an interim route from the current position to the intended destination that terminates at the intended destination at or after the estimated availability time and veers towards a conditional diversion destination based at least in part on the one or more time constraints for the intended destination, wherein positions along a path defined by the interim route are maintained within the allowable flight time from the intended destination; and displaying a graphical representation of the interim route on a display device. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11)

12. A method comprising:
-
obtaining, from a system onboard a vehicle, a current position of the vehicle; obtaining an indication of an estimated availability time for a destination for the vehicle; identifying a conditional destination for the vehicle; obtaining, via a user input device, a maximum travel time from the conditional destination; identifying, via a processing system, a plurality of points from within a region encompassing the destination, the conditional destination and the current position as being within the maximum travel time; identifying an intermediate point between the destination and the conditional destination from among the plurality of points having a minimum travel time to the conditional destination; identifying a first set of route portions from the current position to the intermediate point; identifying a second set of route portions from the intermediate point to the intended destination; and constructing a route from the current position of the vehicle and terminating at the destination that deviates towards the conditional destination as a combination of a first route portion of the first set and a second route portion of the second set, wherein an estimated arrival time at the destination for the route is at or after the estimated availability time; and displaying a graphical representation of the route on a display device. - View Dependent Claims (13)

14. A method comprising:
-
obtaining, from a system onboard a vehicle, a current position of the vehicle; obtaining an indication of an estimated availability time for a destination for the vehicle; identifying a conditional destination for the vehicle; identifying, via a processing system, an intermediate point between the destination and the conditional destination from among a plurality of points having a minimum travel time to the conditional destination; identifying a first set of route portions from the current position to the intermediate point; identifying a second set of route portions from the intermediate point to the intended destination; determining, for each combination of a first one of the first set of route portions and a second one of the second set of route portions, a respective fuel consumption and a respective estimated arrival time associated with the respective combination; determining, for each combination of a first one of the first set of route portions and a second one of the second set of route portions, a respective first difference between a respective fuel consumption associated with the respective combination and a minimum fuel consumption among a plurality of combinations of a first one of the first set of route portions and a second one of the second set of route portions; determining, for each combination of a first one of the first set of route portions and a second one of the second set of route portions, a respective second difference between a respective estimated arrival time associated with the respective combination and the estimated availability time; determining, for each combination of a first one of the first set of route portions and a second one of the second set of route portions, a respective route score comprising a weighted sum of the first difference and the second difference; and identifying a route from the current position of the vehicle and terminating at the destination that deviates towards the conditional destination as the combination of the first route portion of the first set and the second route portion of the second set having a lowest respective route score from among the plurality of combinations of a first one of the first set of route portions and a second one of the second set of route portions, wherein an estimated arrival time at the destination for the route is at or after the estimated availability time; and displaying a graphical representation of the route on a display device.
