Abstract:
1. A method for detecting a potential airborne conflict between an ownship and an intruder, comprising: determining a relative motion trajectory of the ownship and the intruder; generating a plurality of resolution advisories, based upon the determined relative motion trajectory, for each of two or more motion dimensions of the ownship, wherein the motion dimensions comprise a horizontal direction, a speed. and a vertical direction of the ownship, and wherein the plurality of resolution advisories comprise at least two resolution advisories for each of the two or more motion dimensions; determining an alert time for each of the plurality of resolution advisories; dynamically adjusting a size of a protection zone to reduce unnecessary resolution advisories; selecting, for each of the two or more motion dimensions, one of the resolution advisories based on a latest alert time among the determined alert times; and transmitting at least one of the selected resolution advisories to at least one of the ownship or an aircraft control entity, wherein at least the selecting is performed by one or more hardware processors.
