Another aspect of Absolut Minima procedure that seems less than sensible to me, is that the AM for a Visual Approach is set at 800metres (Countrywide?), which is often less than the AM for the various VOR/DME, ILS, NDB, SRA approaches at the same airfields.
In times of low vis, surely we should be encouraging aircraft to make a 'proper' instrument approach, rather than encouraging a dirty dive for the runway to be made at the first call of 'visual'? However with the 'proper' IAP absolute minima often above that of a visual approach, the reverse often seems to happen.
