My point is that alot of this is a very academic discussion. From a
practical standpoint, if we are getting into splitting hairs on the
visability requirements, we should probably be having a serious
discussion of if we should be going by ground!

And *my* point is that, no matter where one sets the visibility limit, it is
plainly obvious that helicopters have more flexibility than airplanes. If
you need at least 1 mile to be safe in a helicopter, you need 2 or more
miles visibility to be safe in an airplane.
