The present invention in its various aspects is as set out in the appended claims. The present invention provides 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.

In one aspect of the invention, the generation of routes are based on information received from one of a Flight Management System (FMS) or a Flight Control System (FC).

In another aspect of the invention, 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.
