1. A method of providing aircraft threat envelope protection for an aircraft, comprising:
populating a threat envelope data structure embodied in a computer-readable medium to store a plurality of trigger conditions, each of the plurality of trigger conditions associated with at least one threat of a plurality of different types of threats associated with the aircraft;
iteratively generating projected trajectories of the aircraft, where at each iteration a plurality of projected trajectories are generated, with each iteration of the plurality of projected trajectories describing different possible aircraft paths through spacetime that each begin at a current aircraft state;
responsive to a detected threat of the plurality of different types of threats, associating a trigger condition of the plurality of trigger conditions to a specific trigger point in spacetime along at least one of the plurality of projected trajectories, where the specific trigger point identifies where in spacetime a recovery action should be initiated based on the trigger conditions associated the detected threat;
deprecating selected projected trajectories of the plurality of projected trajectories during conditions when such selected projected trajectories are computed as not viable to recover from any detected threat of the plurality of different types of threats; and
initiating an aircraft protective response in response to:
all but one of the plurality of projected trajectories having been deprecated such that only one non-deprecated projected trajectory remains viable; and
the aircraft is within a determined proximity to a closest trigger point of the one or more specific trigger points along the one non-deprecated projected trajectory.
