US Patent 7930102 Systems and methods for constructing variable offset paths

A method is provided for constructing an offset, and includes constructing the capture path, which includes selecting a capture path start point on a first leg of the flight path and selecting a first capture path angle; determining whether a first capture path segment extending from the capture path start point at the first capture path angle intersects a) a first bisector or b) a first bisector backcourse; establishing, if the first capture path segment intersects the first bisector backcourse, the first capture path segment as the capture path; establishing, if the first capture path segment intersects the first bisector, the intersection as a first point; determining one or more subsequent capture path segments until the one or more subsequent capture path segments intersect a subsequent bisector; and establishing the first capture path segment and the one or more subsequent capture path segments as the capture path.
