Interesting! I wonder how that works? Hard to have a visual if you can not
see? Not trying to be a smart ass or anything just trying to get the whole
picture.
For purposes of visual versus instrument flight rules, the required
visibility conditions are specified for purposes of separation, not
navigation or aviation. That is, as long as you can see well enough to keep
from colliding with other aircraft, there's no requirement to be able to
tell where you are without use of instruments, or even to be able to keep
the plane upright without use of instruments.
