Abstract

Critical differences in the position and motion of aircraft in congested N-dimensional airspace are highly discernible when processed and mapped onto a parallel N-coordinate plane. Trajectory intersection in both time and space may be constantly monitored. The airspace may be accurately controlled by descriptively and prescriptively configuring proposed trajectories and monitoring critical differences before assignment to aircraft. Attributes such as angular deviation, in addition to closing speed and distance, can be evaluated.
