Talk:ICAO airport code

message: The History paragraph doesn't cite any sources. Does anyone have a source for this information? I'd also like to find out how other areas (Africa, Asia, Australia) were assigned, which might be in the same source. All the 'sources' I can find seem to just reference this list and say "Oh and Australia is Y and China is Z," and the only other source i have is an anecdote from an old air traffic controller (worked ATC in the 90's) saying Australia got Y and China got Z because they put their submissions in late. I'm going to mark the whole paragraph with Citation Needed

message: There are a few entries in the list that I'm not really fond of, but since I don't know whether the names used in the list are "official", I don't want to edit it.
1. K for "mainland USA", but a separate letter for Alaska. To me, Alaska is on the mainland. "Contiguous 48 states" seems more appropriate to me, if the intention is to exclude Alaska, Hawaii, and the overseas territories.
2. "F - southern Africa " includes central Africa too. Shouldn't that be indicated?
3. WP, Timor Leste. East Timor seems more appropriate on the English wikipedia, to me.
So, if the things mentioned above are "as stated by ICAO", just ignore this. But if they're not (and you can get a source on that), go ahead and edit accordingly! 85.224.199.36 09:09, 15 October 2007 (UTC)
thread_title:  Is that list "official"? 

message: Am I correct in assuming that the letters of airport and navaids (VORs, etc.) must be upper case?  Are numbers allowed?  Can anyone name the ICAO document containing the guidelines that cover the naming rules?
*To the anon, convention always places them in uppercase. I have seen no instance where they are different. Burgundavia (✈ take a flight?) 23:26, May 16, 2005 (UTC)
All letters that identify a navaid in air navigation will be upper case, as can be observed  in any airport chart. Numbers are not allowed in airport codes, VORs, NDBs or localizer codes, however, they can be used in GPS coords/waypoints, mostly relating to approaches or landings (i.e. IF01L would be the initial approach fix for runway 01L, with disregard to how many identically named waypoints exist. These are marked with four-dented stars and are associated with a particular airport.
As a partial explanation, I think that the "I" prefix is not used due to many ILS localizers having their own codes, mostly starting with "I" (i.e. INAT in Panama City 03R, IJFK in Kennedy's 4R, etc.) - 12:25 GMT, August 4th, 2012  — Preceding unsigned comment added by 201.226.56.3 (talk) 12:26, 4 August 2012 (UTC)

message: The article provides good information about the mapping of the first or first two letters of the ICAO code to the location. This is best shown as a map, for example: South Africa as "FA", Moscow-area of Russia as "UU", Southern India as "VO" etc. In some cases such as the continental USA and Canada, the second letter does not usually map to the location, so they could go by the first letter alone as "K" or "C".

message: I understand that ICAO codes are unique to a given airport for a given moment in time. Can an airport be assigned more than one ICAO code simultaneously? For example, Al Asad Airbase currently shows two ICAO codes. Are these both currently valid, or is one of them an old code, and the other a new code that replaced it?  —Preceding unsigned comment added by 199.82.243.104 (talk) 21:21, 22 April 2011 (UTC)
replies: text: I can't speak for the example given, but there are similar cases: the grounds of Brussels National airport include both EBBR Zaventem for the civil operations and EBMB Melsbroek for military ops; these have a separate terminal. Jan olieslagers (talk) 02:42, 23 October 2016 (UTC)
replies: text:  The example of EBBR/EBMB is a good one. Off topic, sometimes ICAO codes are updated/replaced. For example, when Johannesburg airport was renamed from Jan Smuts to Oliver Tambo, its code went from FAJS to FAOR. cagliost (talk) 08:40, 30 August 2023 (UTC)

message: In practice, Antarctica doesn't have a single ICAO code, as each airport uses codes assigned for their respective country:
* EG: United Kingdom

* Y: Australia
Certain online airport databases have codes starting with AA or AT that appear to be ad hoc inventions.

And these codes often began with a Z. I seem to remember that such a code was assigned to Brussels South ("midi", to some :) ) railway station at one time, though it seems to be unassigned since.
