Tony is right, but I'll expand. There is no such thing as a fly by or fly over fix. The terms fly by and fly over are only applicable to waypoints. A fix is basically something that can be identified using any conventional navigation method or GPS. A waypoint can only be identified by GPS/FMS or some other global positiong method. Any procedure that requires the use of global positioning will indicate on the appropriate chart if a waypoint is a fly by or fly over type.
