The following FAA standard formulas with test cases passing have recently been implemented with more to follow. Click on the link to open the FPAssistant SDK documentation.
WGS84CrsIntersect – Computes the coordinates where two geodesic curves intersect
WGS84Destination – Computes destination point based on course and a static point
WGS84Distance – Distance between two points
WGS84PtIsOnGeodesic – Algorithm determines if a point lies on and within the bounds of a given
geodesic.
More formula from the FAA Doc 8260.58 will be added in due course.
