In Papua New Guinea, I provide a "Cloudbreak" approach whenever the Missed Approach Point has to be located outside the circling area applicable to the highest category of aircraft that can use the approach. The reason for this is invariably related to obstacles in the vicinity of the aerodrome, or in the missed approach segment.
The chart shows a visual DR leg from the MAPt to the aerodrome, but the pilot is well and truly on his own if he proceeds beyond the MAPt and subsequently looses visual reference. The MDA for the approach takes no account of obstacles along the visual DR leg, or in the circling area - unless they happen to fall within the protection area for the final or missed approach segments.
This type of approach is always a last ditch effort to provide some sort of instrument approach when nothing else works. I've even be known to employ a Cloudbreak for a GPS approach!
And, yes, the AIP describes the Cloudbreak procedure so that pilots understand the limitations that apply to them.
