   I have had trouble all along with the 3" and 12" number issue.  The
relationship of the size of the N-numbers to the speed of the aircraft
seems completely irrelevant.  I find it difficult to believe that
anyone can read the 3" numbers on ANY airplane in flight, regardless of
speed, so that cannot be the issue.  Is the application of the rule for
aircraft on the ground?  If so what in the world does that have to do
with CAS?  In my mind, it would make more sense to pick the size of the
numbers in proportion to the size of the craft.  Can someone shed
some light on what in the world the thinking was behind this rule?
At least then I'd have some peace about it!

[Don't forget about the 12" number requirement when flying outside the
contiguous 48 states... flight into ADIZ or foreign countries also
require 12" numbers.  Fortunately, we can apply them temporarily for
flights across the border, so it's really not that big an issue.  As for
the logic behind the differences in number sizes based on CAS... as far
as I'm concerned it was probably dreamt up by some bureaucrat who
wanted red numbers on blue airplanes, black/gold striped numbers on silver
ones, and a multitude of other arcane color combinations based on
something else equally as inane... this was their compromise to
shut him up <vbg>.
