If the aeroplane is approaching the capture zone at an intercept angle of greater than 155 degrees, the autopilot might fly a circular course to intercept the INS course.
This means that the intercept angle could be between 0 and 180...and passing out of 90 would be in fact kinda "backcourse" intersect, is this right? In this case, the ap would command a circular route off the active course until reach 25 deg of heading intercept?
Thank you for the info anyway

PS: Is it possible to fly a procedure turn in a CIVA INS equiped a/c?
