Intercept Course-From a Waypoint
Course-From operation allows you to navigate from a waypoint on a selected
course. When the Course From operation is executed, the CDI will indicate
FROM and the flight plan will go into Suspend mode (the SUSP annunciator
will appear); it will not automatically sequence the flight plan waypoints. The
airplane will track outbound on the selected radial until instructed otherwise.
