Abstract

Methods and systems are provided for facilitating analysis and selection of a destination for operating a vehicle. One exemplary method facilitating analysis of landing an aircraft at an airport involves displaying a map of the airport that includes a graphical representation of a runway at the airport, determining a runway viability parameter for the runway using current status information associated with one or more of the aircraft and the airport, and displaying indicia of the runway viability parameter on the map in graphical association with the graphical representation of the runway, thereby providing indication of the value or state of the runway viability parameter for that runway on the airport map.

Claims

1. A method of facilitating analysis of landing an aircraft at an airport, the method comprising:

displaying, on a display device, a map of the airport, the map including runway symbology corresponding to a runway at the airport;

determining a predicted stopping distance for the aircraft based at least in part on meteorological information associated with the airport; and

rendering a filled portion of the runway symbology on the map, wherein a length of the filled portion of the runway symbology corresponds to a ratio of the predicted stopping distance to a length of the runway.

2. The method of claim 1, further comprising displaying symbology indicative of a second runway viability parameter on the map proximate the runway symbology.

3. The method of claim 2, wherein:

the second runway viability parameter comprises a windspeed component determined based at least in part on current meteorological information associated with the airport; and

displaying the symbology comprises displaying a windspeed symbol representative of the windspeed component proximate an approach end of the runway symbology.

4. The method of claim 1, further comprising displaying outline symbology encompassing at least a portion of the runway symbology.

5. The method of claim 4, further comprising rendering an intermediate region between the outline symbology and the runway symbology using a visually distinguishable characteristic indicative of a runway viability parameter.

6. The method of claim 1, wherein rendering the filled portion comprises rendering the filled portion using a visually distinguishable characteristic relative to a remaining portion of the runway symbology.

7. The method of claim 1, wherein determining the predicted stopping distance comprises determining the predicted stopping distance for the aircraft based at least in part on current meteorological information associated with the airport and a predicted landing weight for the aircraft.

8. The method of claim 7, further comprising identifying the visually distinguishable characteristic based on the current meteorological information associated with the airport.

9. The method of claim 7, further comprising determining the predicted landing weight of the aircraft based at least in part on a current amount of fuel remaining onboard the aircraft.

10. The method of claim 7, further comprising displaying available runway length symbology encompassing at least a second portion of the runway symbology, wherein a ratio of an available runway length to the length of the runway corresponds to a second length of the second portion of the runway symbology encompassed by the available runway length symbology.

11. The method of claim 10, further comprising identifying the visually distinguishable characteristic based on the stopping distance relative to the available runway length.

12. The method of claim 1, further comprising determining a predicted landing weight for the aircraft based at least in part on current status information associated with the aircraft and current meteorological information associated with the airport, wherein the predicted stopping distance is influenced by the predicted landing weight.

13. The method of claim 1, further comprising obtaining, by a processing system onboard the aircraft via another system onboard the aircraft, a current status base parameter value associated with the aircraft, wherein:

determining the predicted stopping distance comprises calculating, by the processing system, a value for a complex runway viability parameter based at least in part on the current status base parameter value; and

a characteristic of the filled portion is influenced by the value for the complex runway viability parameter.

14. A computer-readable medium having computer-executable instructions stored thereon that, when executed by a processing system coupled to the display device onboard the aircraft, cause the processing system to perform the method of claim 1.

15. A system comprising:

a display device having an airport map including runway symbology corresponding to a runway at an airport displayed thereon; and

a processing system coupled to the display device to;

determine a predicted stopping distance for an aircraft based at least in part on meteorological information associated with the airport; and

render a filled portion of the runway symbology on the map, wherein a length of the filled portion of the runway symbology corresponds to a ratio of the predicted stopping distance to a length of the runway.

16. The system of claim 15, further comprising a meteorological system coupled to the processing system to provide the meteorological information corresponding to the airport.

17. The system of claim 16, further comprising an onboard system coupled to the processing system to provide current status information for the vehicle, wherein the processing system determines the predicted stopping distance based at least in part on the meteorological information and the current status information.

18. The system of claim 15, further comprising:

an avionics system coupled to the processing system to provide one or more current status base parameter values to the processing system; and

a communications system coupled to the processing system to provide current meteorological information for the airport, wherein;

the processing system is configurable to;

determine the predicted stopping distance based at least in part on the one or more current status base parameter values and the current meteorological information.

19. A method of facilitating analysis of an airport, the method comprising:

displaying, on a display device onboard an aircraft, a map of an airport, the map including runway symbology corresponding to a runway at the airport;

obtaining, by a processing system onboard the aircraft, current information associated with one or more of the vehicle and the airport from one or more onboard systems coupled to the processing system;

calculating, by the processing system, a predicted stopping distance for the aircraft at the airport based at least in part on the current information; and

rendering, by the processing system, a filled portion of the runway symbology using a visually distinguishable characteristic, wherein a length of the filled portion of the runway symbology corresponds to a ratio of the predicted stopping distance to a length of the runway.

20. The method of claim 19, wherein:

obtaining the current information comprises obtaining one or more base parameter values quantifying a current status;

calculating the viability parameter comprises calculating a complex parameter value based on the one or more base parameter values; and

the filled portion is influenced by the complex parameter value.
