Descent B010 in G airspace is exactly what is done in the company for whom I work on the ambulance flights. This is often in some quite ......er.......challenging(!) conditions.
The trick is to be thoroughly familiar with the region and use whatever navaids are available eg I often fly a 12.5 DME ARC over the ocean to position myself over a village from which I can track visually in minimum VMC conditions to another town which is directly on final. I have a radial from a regional airport 25nm away that marks the furthest point around the arc I should fly - there are hills further on - & fixes the initial town. If I can't get visual then I can try an alternative procedure using similar techniques from another direction. After that it's a diversion to an ILS.
