Batman,
Sounds like a particularly difficult manoeuver if you've lost visual contact with the Runway(s). You break from the instrument procedure to perform a circle to land. After, say, 120 degs of a 270 turn (eg Kathmandu), you find yourself in cloud and, having lost visual contact, start trying to work out how to get back round to the instrument missed appproach.
Does anyone have experience of flying such an approach?
