Identifier?

I see some references to this field called KCJJ.

AirportCodesa.com says its ICAO is KCJJ

AirportGuide.com says ICAO is KCJJ, FAA is CJJ

Hello Flight

Wikipedia for Iowa: ICAO is KCJJ, FAA is CJJ

Sadly I can't put in the URLs into this form for reference.

re: Identifier?

Yes, that is correct. When an airport in the "lower 48" contiguous United States has an FAA id that consists of only letters, it also has an ICAO code that consists of a "K" plus those same three letters. I am not aware of any airport in the lower 48 that does not obey that rule. In Alaska, Hawaii, Puerto Rico and US possessions, the mapping is lot less regular.

Reply to @ptomblin: the problem is that the ICAO doesn't recognize all of the KXXX identifiers. For example, Norwood Airport (FAA: OWD) is referred to as "KOWD" in GPS databases, but AFAIK, there is no "KOWD" ICAO code.

Reply to @david: http://www.activitae.com/cgi-bin/htmlSearch.pl - I don't know if this actually looks at the ICAO database, or if it just applies the standard rule to the FAA ids. But it lists KOWD (and not abominations like K7G0 like I've seen in some places).

Reply to @ptomblin: you have to pay for the official list, but here's a copy (re)published by Mexico in 2010: http://www.mexico.icao.int/icaoaspa2010/ECCAIRS/Documentation/Taxonomy/R4CDLocationIndicatorsByState.pdf

Reply to @david: I don't trust that list, because it doesn't list Genesee County Airport, which changed its FAA id from 3G8 to GVQ because it had weather reporting and so therefore needed an ICAO identifier KGVQ. That happened when the US adopted METAR/TAF back in the late 1990s/early 2000s.

re: Identifier?

Reply to @ptomblin: I have an old paper copy of the official ICAO "Location Identifiers" doc (ICAO Doc 7910/128) from June 2008. It lists no identifier "KGVQ". The closest ones are "KGUS" (Grisson AFB) and "KGVW" (Kansas City, Richards-Gebaur Airport). I suspect that someone was using "ICAO" informally, as a synonym for "four-letter all-alpha identifier".

The confusion over ICAO identifiers, especially in the US, is the main reason that I went for "GPS code" instead with OurAirports.
