I was totally converted to the idea of monitored approaches 25 years ago, and introduced it at a former airline where I was honcho. Unfortunately that airline went bust, though that was nothing to do with our approach policy!
As far as I am aware, no other airline in Australia has embraced the concept. I have never seen it in any SOPs, most of which appear to have evolved from Ansett or TAA days of old when the mighty DC 3 was flagship, men were men and barmaids ate their young. On the odd occasion where I have raised monitored approaches for consideration I have been told firmly to butt out because others know a better way of doing things in bad weather. CASA do not appear to have any great interest in this subject, either. Good oh.
I would appreciate information on any domestic airline in Australia that has monitored approaches as policy, and what weather minima makes it mandatory.
