Abstract

Integrated surveillance systems and methods for processing multiple sensor inputs and determining a best route for avoiding multiple hazards. An example method performed on a first aircraft includes generating a plurality of routes for avoiding a previously determined alert from a first advisory system. Then, probability of success information is generated at other advisory systems for each of the plurality of routes. The best route of the plurality of routes is determined based on the generated probabilities and output to the flight crew or other aircraft. The probability of success information includes a previously defined uncertainty value. The uncertainty value corresponds to quality of data provided to or provided by the respective advisory system.

Claims

1. A method comprising:

on a first aircraft,

generating a plurality of routes for avoiding a previously determined alert from a first advisory system;

generating probability of success information at other advisory systems for each of the plurality of routes;

determining a best route of the plurality of routes based on the generated probabilities; and

outputting the determined best route.

2. The method of claim 1, wherein the probability of success information comprises a previously defined uncertainty value, wherein the uncertainty value corresponds to quality of at least one of data provided to or provided by the respective advisory system.

3. The method of claim 1, wherein generating the plurality of routes is based on information received from one of a Flight Management System (FMS) or a Flight Control System (FC)

4. The method of claim 1, wherein outputting comprises outputting the determined best route to at least one other aircraft.

5. The method of claim 4, further comprising:

on the at least one other aircraft,

generating a plurality of routes based on the outputted best route;

generating probability of success information at local advisory systems for each of the plurality of routes;

determining the best route of the plurality of routes based on the generated probabilities; and

outputting the determined best route.

6. The method of claim 1, further comprising receiving at least one of aircraft traffic or weather hazard information from at least one of ground or satellite-based systems, wherein generating the plurality of routes is based on the received at least one of aircraft traffic or weather hazard information.

7. The method of claim 1, wherein the first and other advisory systems are selected from the group consisting of:

a Traffic Alert Collision Avoidance System (TCAS), an Enhanced Ground Proximity Warning System (EGPWS), a Weather Radar, and an Automatic Dependent Surveillance-Broadcast (ADS-B) In System.

8. The method of claim 1, wherein the first and other advisory systems are three or more of a Traffic Alert Collision Avoidance System (TCAS), an Enhanced Ground Proximity Warning System (EGPWS), a Weather Radar, an Automatic Dependent Surveillance-Broadcast (ADS-B) In System.

9. A system comprising:

on a first aircraft,

a first advisory system configured to generate a plurality of routes for avoiding a previously determined alert based on the generated flight information;

at least one other advisory system configured to generate probability of success information for each of the plurality of routes; and

a component configured to determine a best route of the plurality of routes based on the generated probabilities and output the determined best route.

10. The system of claim 9, wherein the probability of success information comprises a previously defined uncertainty value, wherein the uncertainty value corresponds to quality of at least one of data provided to or provided by the respective advisory system.

11. The system of claim 9, wherein the first aircraft further comprises at least one of a Flight Management System (FMS) or a Flight Control System (FC) for generating flight information, wherein the first advisory system generates the plurality of routes based on the generated flight information.

12. The system of claim 9, wherein the component outputs the determined best route to other aircraft.

13. The system of claim 12, further comprising:

on the other aircraft,

a first component configured to generate a plurality of routes based on the outputted best route from the first aircraft;

one or more advisory systems configured to generate probability of success information for each of the plurality of routes;

a second component configured to determine a best route of the plurality of routes based on the generated probabilities and output the determined best route.

14. The system of claim 9, wherein the first aircraft further comprises a component configured to receive at least one of aircraft traffic or weather hazard information from at least one of ground or satellite-based systems, wherein the first advisory system generates the plurality of routes based on the received at least one of aircraft traffic or weather hazard information.

15. The system of claim 9, wherein the first and the at least one other advisory system are selected from the group consisting of:

a Traffic Alert Collision Avoidance System (TCAS), an Enhanced Ground Proximity Warning System (EGPWS), a Weather Radar, and an Automatic Dependent Surveillance-Broadcast (ADS-B) In System.

16. The system of claim 9, wherein the first and the at least one other advisory system are three or more of a Traffic Alert Collision Avoidance System (TCAS), an Enhanced Ground Proximity Warning System (EGPWS), a Weather Radar, an Automatic Dependent Surveillance-Broadcast (ADS-B) In System.
