How does one differentiate a "fly by" from a "fly over" waypoint? I am referring more to Terminal Area Procedures (SID, STAR, Approach), rather than en route waypoints, airways etc. How do I know if such a waypoint is a &quot;fly over&quot; or not?
Especially for some RNAV procedures, where the turn to join the final approach course can be 90 degrees. I have already read the &quot;Fly over or fly by question&quot; but I did not find a reply to the above, although the example quoted and shown in that question was a very good example of what I am asking.
A flyover waypoint will have a circle drawn around it on a chart, whereas a fly-by waypoint will not. (Easy to remember: the circle looks like the O in Over)

The symbols for a fly-by and a flyover waypoint in aeronatutial maps and charts can be differenciated by the circle surrouning flyover waypoints.
