Where are these regs (required documents onboard) anyways?

As I said, I couldn't (quickly) find them in the FAR/AIM.

When I first learned the memory aid for required documents, it was
"ARROW".

When I inquired why sometimes I saw "AROW", I remember being told that the
second "R" was dropped because while flying within the USA you don't need
the "Radio License".

I glanced through the FAR/AIM and couldn't quickly put my finger on this,
so
I'm putting it out he what's the deal on this? I have seen what may be
conflicting indications about this -- for instance, in the thread about
ramp
checks, etc.

When do you need the "Radio License" document, and who cares about it
(e.g.,
is the FAA or the FCC)?
