1. A collision avoidance method for an aircraft traversing a flight path, the method using one or more processors in communication with a memory having executable instructions stored therein, the method comprising:
receiving obstacle tracking data for one or more potential obstacles for the aircraft along or proximate to the flight path, the obstacle tracking data further including data related to one or more contextual obstacles proximate to the flight path;
determining, based on the obstacle tracking data as received, a predicted miss distance between the aircraft and each of the one or more potential obstacles along the flight path;
determining a plurality of alternate flight path options, each of the plurality of alternate flight path options including a corresponding alternate flight path that deviates from the flight path,
wherein each alternate flight path option, of the plurality of alternate flight path options, is equal to or greater than:
a threshold distance, and
a threshold prediction confidence value;
assigning at least two of the plurality of alternate flight path options a corresponding safety parameter value, the corresponding safety parameter value based on at least the predicted miss distance between the aircraft and at least one of the one or more potential obstacles;
selecting an alternate flight path from among the plurality of alternate flight path options, the selected alternate flight path selected based at least on;
the selected alternate flight path having a lowest safety parameter value,
the selected alternate flight path avoiding the one or more potential obstacles, and
at least one of the one or more contextual obstacles proximate to the flight path;
automatically transmitting the selected alternate flight path to a guidance system of the aircraft; and
automatically maneuvering the aircraft using the guidance system to follow the selected alternate flight path.
