No doubt about that. Got to always be in VMC. However, I guess the question is whether the forecast really means that the VIS is likely to be say 2000m or whatever (less than 5K) across every square inch of the AREA. Today for example, (haven't) checked them all by the way) that could be all of Area 44, 40 and 20). It's been that way for the last few weeks, every day, by the way.
