Waypoints entered in the en route segment may be treated as either fly-by waypoints or fly-over waypoints. For both types of waypoints, the system will transition using a precisely calculated turn on course to the next waypoint.

If the system determines the flight plan leg geometry cannot support fly-by navigation for a waypoint sequence in the current flight plan, it will change a fly-by waypoint to a fly-over waypoint automatically. A roll steering path or future roll steering path may be displayed after the fy-over waypoint until the roll steering path aligns with the course leg connecting the fly-over waypoint and the following waypoint in the flight plan. This system generated fly-over waypoint will not display the fly-over symbol.

A fly-over waypoint may also be manually designated by the pilot, in which case, the fly-over waypoint symbol is displayed.
