BOAC,
I agree, a circle to land is as you say the visual segment after breaking off a instrument approach. You will never find a circle to land chart, the minima will be posted on the bottom of the approach you are flying unless circle to land is not allowed off that approach then no circling minima will be published..
What Meekal may be referring to is possibly a vor or ndb approach which starts off by flying the arc to the FAF.
