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.



For those of you who fly VFR to Canada, I do not believe that
interpretation would stand up. Canadian rules specifically mention:


602.114 [and 602.115]

No person shall operate an aircraft in VFR flight within controlled [and
uncontrolled] airspace unless

(a) the aircraft is operated with visual reference to the surface;



USA can fly VFR as long as the visibility and cloud clearance rules are
followed. We can fly over the top of the clouds with no surface visible...


Canada has Over-the-top rules as well, but the flight-visibility and cloud
clearance rules change from those of "VFR-as-defined". In other words:
VFR-over-the-top is specifically defined in the regulations to be something
slightly different than "VFR".
