It does seem a mountain from a mole hill discussion. These comments relate to a normal IFR airline operation. I do appreciate, and have done many times, approaches into pure visual airfields with perhaps a cloud-break first.
If you are making a visual to a runway with an approach aid why NOT set the minima for that? You would have briefed before TOD and out of sight of the airfield, therefore would have briefed and set up for relevant approach.
If you are making a visual direct to a circling runway why NOT set circling minimum?
If you are making a pure visual why NOT set THR + 500' as a trigger for the stable/GA/continue decision point?
I don't understand guys wanting to overcomplicate a simple scenario. Do guys really re-set bugs during approach? If you are making a short turn visual onto a rwy with an ILS transmitting - for which you have the bugs and aids set up - is anybody going to change anything, or just fly the damn a/c?
