Send Clowns,
You would have to look somewhere pretty obscure to find a licence that is not ICAO
Like, erm, let's think about this. How about the UK?
In the UK, you can now get two different types of private license. The PPL is an ICAO license - it meets the standards set by ICAO, the same standards as licenses issued all over the world. The NPPL is
not an ICAO license. There are some ICAO requirements which it does not meet, and as such it is not valid outside of the UK.
Send Clowns, of course, knew this, but had temporarilly forgotten it!
