Request to change en title to FAA airport code

I want to have the title changed to FAA airport code, in order to be consistent with the change I've proposed for the ICAO airport code and IATA airport code properties. Harryboyles (talk) 10:34, 7 March 2013 (UTC)

Have done so. Harryboyles (talk) 10:40, 7 March 2013 (UTC)

format constraint

i changed the pattern from [A-Z][A-Z][A-Z] to [A-Z0-9][A-Z0-9][A-Z0-9][A-Z0-9]?, since thats what a three-letter or four-letter alphanumeric code looks like (e.g. Q2784927) --Akkakk 22:15, 4 June 2013 (UTC)

Wonder if FAA LID can apply outside USA

Example : Saint-Louis-de-France Aerodrome (Q3913049) and Ulithi Airport (Q11824803)Bouzinac (talk) 21:22, 22 January 2019 (UTC)

why string not external-id?

@Sven_Manguard: Please change the type of IATA airport code (P238), ICAO airport code (P239), FAA airport code (P240) from "string" to "external-id" --Vladimir Alexiev (talk) 09:10, 18 November 2020 (UTC)
