Could we try and move on from the original thread. I am actually quite interested in these non-icao approaches and the views of how (or if) any of the flight deck technology should be used in the visual segment.
For Anonystude, yes that is the book answer. But in several cases you can not see the airfield environment from any part of the approach up to and including the MAPt. Clearly they did not intend every approach to end in a missed approach, so there is something beyond the basic rule.
