Abstract

A trajectory-based sense-and-avoid system for use on an aircraft is provided that utilizes 4-D constructs, such as 4-D trajectories or 4-D polytopes, to maintain separation from other aircraft and/or to avoid collisions with other aircraft. In certain embodiments the trajectory-based sense-and-avoid system utilizes 4-D trajectories provided from an external source and/or 4-D trajectories estimated based on a variety of data sources during operation.
