I don't think this is right. In Class B airspace, the only requirement is
to be
clear of clounds. That means that an aircraft could be in the clouds at
(for
example) 5,000 ft. and other aircraft could be VFR at 4,500 or 5,500, be
clear
of the clouds and be quite legal.


True, but since most airspace is other than Class B it is right in most
airspace.
