who would feel comfortable descending in manual flight below DA without the target in sight.?
But that's exactly what existing minima expect you to do
Indeed; I expressed it badly. By target I meant one more of the 'required shopping list' of items. Required visual reference as we call it. They are official approved aerodrome structures, not car parks or even just 'lights'. There have been enough NPA CFIT crashes where we heard the PM call "ground contact" well before MDA and sucked PF into continuing into the gloom. Vertical visibility at 500' is not 2400m forward vis.
Now someone has told us the published meteo it is even easier to understand how they became sucked into being relaxed and continuing. If correct that is a very large swiss hole in the process.
