US Patent 9640079 Methods and systems facilitating holding for an unavailable destination

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.
