Canada has done that officially -- all Canadian airport codes are now
four-letter ICAO codes starting with 'C', even the ones for tiny grass
strips or floatplane bases.  The last I checked, though, the US had
not yet done the same (even though it owns the prefix 'K', so could
easily do so with no conflicts); only the airports that had proper
IATA codes now have ICAO codes, as far as I can tell.

Robin's database should use ICAO codes where available, of course;
sooner or later, the US will switch over all its airports officially,
so KC83 will be a real identifier, but they're not quite there yet.

All the best,

The 3 letter FAA airport codes have been prepended with a K but they never 
used to be.
e.g. C83 now equals KC83

Is this normal? Why the change?
Are these official ICAO codes?
