Methods and systems for safe landing at a diversion airport
First Claim
1. A system comprising:
- a display device to display a map associated with a vehicle;
an input device to obtain one or more constraints for diverting the vehicle;
a meteorological system to provide meteorological information; and
a second system onboard the vehicle to provide a current value for a vehicle characteristic, wherein the vehicle characteristic comprises a weight of the vehicle or a fuel remaining onboard the vehicle; and
a processing system coupled to the meteorological system, the second system, the display device and the input device to;
determine a route from a current position of the vehicle to a diversion destination based at least in part on a safety threshold for accessing the diversion destination and the one or more constraints, wherein;
the route satisfies the one or more constraints and results in a predicted value for the vehicle characteristic satisfying the safety threshold at the diversion destination; and
the predicted value for the vehicle characteristic is determined based at least in part on the current value, the route, and the meteorological information corresponding to the route; and
display a graphical representation of the route on the map.

Abstract
Methods and systems are provided for generating a route that facilitates navigating a vehicle to a diversion destination while satisfying applicable safety thresholds or other constraints, such as a maximum landing weight. One exemplary method of facilitating an aircraft landing at a diversion airport involves obtaining a current position of the aircraft, identifying a landing threshold influenced by a characteristic of the aircraft, obtaining one or more constraints associating with diverting to the diversion airport, and determining a route from the current position to the diversion airport based at least in part on the landing threshold and the one or more constraints. The route satisfies the constraints and results in a predicted value for the aircraft, e.g., a predicted aircraft landing weight, that satisfies the landing threshold. A graphical representation of the route is displayed on a display device onboard the aircraft.
