The radio license requirement was dropped, IIRC, in 1998 for domestic
flights. You are still supposed to have it for international flights, but no
one ever checks for it. It is an FCC requirement. The FAA in the United
States and its corresponding agencies in other countries do not feel it is
their responsibility to enforce FCC rules. Neither do the different
countries' customs and immigration agencies. And the radio licensing
authorities do not feel they have the time or budget to go chasing after
airplanes that do not have radio licenses.

In the case of Canada, at least, the requirement of a radio licence for
aircraft and boats (small private boats at least) was dropped some time
ago - probably about the same time that the USA did it. So, in this
case, it's not that nobody is enforcing the rules, the rules have
disappeared.

But other countries haven't dropped the requirement, so you're still
supposed to have the licence for flights outside the US and Canada (and
maybe Mexico; don't know about that one).
