Aerodrome refs other than ICAO, IATA, FAA

In Canada, I observe the use of the tclid tag, which is probably filled with these values, but there is no description of this tag on the wiki, much less a Proposal process for it or a forum discussion about it.

There’s also tc=*, which is slightly older and even more common at 138 occurrences, versus 113 for tclid=*.

I didn’t see any information here about military bases overseas, perhaps this information is not public or hard to access, but there are three-character identifiers for Canadian airfields here. As far as I have seen these are the last 3 characters of the Transport Canada assigned code (TC LID), however I have not analysed them all.

Right, the FAA LIDs for Canadian airfields are clearly related to TC LIDs, with the exception of the C prefix. Maybe the difference doesn’t matter for OSM purposes. For example:

Location	FAA LID	TC LID
West Coast General Hosp Secondary Aerodrome, Port Alberni, B.C.	BK5	CBK5
St Stephen, N.B., Secondary Aerodrome[1]	CS3	CCS3
Markham Secondary Aerodrome, Toronto, Ont.	NU8	CNU8
