Abstract:
1. A system for constructing an offset at an offset distance from a flight plan with a plurality of legs and a plurality of waypoints for flight by an aircraft, the system comprising: an input device configured to receive inputs related to a capture path angle and a capture path start point from a pilot; a memory coupled to the input device and configured to store data related to the flight plan and the offset; and a processor configured to retrieve data from the memory and to construct the offset based on the capture path angle and the capture path start point for flight by the aircraft, wherein the offset includes a capture path, a parallel path, and a return path, and wherein the processor is further configured to determine whether a first capture path segment extending from the capture path start point on the first leg at the first capture path angle intersects a) a first bisector extending from a first waypoint between the first leg and a second leg or b) a first bisector backcourse extending from the first bisector parallel to the first leg at the offset distance; wherein the processor is further configured to establish, if the first capture path segment first intersects the first bisector backcourse, the first capture path segment as the capture path.
