Yeah, but I just copied that idea from Garmin, who use K at the
beginning of the ident to distinguish US airports from similarly
named navaids.

The Canada Flight Supplement has also gone to four-letter identifiers
for all airports. The GPS age will probably hasten this change along
everywhere, since it effectively gives airports their own namespace.


All the best,
