# Should the tag be air-traffic-control or atc (and other abbreviations)?

We currently have an and tag. Which one should be used? In general, when should common terms be abbreviated in tags and when should they be spelled out?

I would recommend going with , for the following reasons:

• It's much more easily discovered through auto tag completion
• It's a much better SEO benefit

We can then make a synonym of it if the use persists, which also solves auto tag completion of those that would naturally start typing the acronym instead of the phrase.

This isn't a blanket suggestion, as there are some things that just won't fit in a tag and require a creative compromise, but it's generally the best way to approach it.

• Agreed! This covers a couple of scenarios and the plain text is less jargony. – egid Dec 18 '13 at 6:49
• Plus of course, that atc is an abbreviation of "auto tag completion". – Mr Lister Dec 18 '13 at 8:39
• I much prefer the longhand to lots and lots of acronyms and abbreviations – Jamiec Dec 18 '13 at 9:54
• @MrLister Woah, that tiny but delicious piece of irony almost slid right by me :) I think that settles it once and for all then! – Tim Post Dec 18 '13 at 10:09
• keep the synonym though, a lot of people (most?) in aviation refer to it as ATC (ay tee see), and only rarely use the long form. Probably even would have to think for a couple of seconds to remember what it's an abbreviation off... :) – falstro Dec 19 '13 at 18:39
• @TimPost I think you can safely go ahead and create this synonym (Dang it feels strange not having modlike powers to abuse! Waiting for edit approvals, can't create my own tag synonyms - I'm really slumming it here! 0_o ) – voretaq7 Dec 26 '13 at 5:32

I originally agreed with Tim, but have since changed my mind as we have progressed through the beta and have been creating more tags:

Aviation has tons of acronyms, and this can make it hard for new pilots and non-pilots to understand some of the conversations. However, it is also standard usage and there is a long list of them in the pilot-controller glossary (among other places). In addition:

• VERY rarely do I see "air traffic control" used in an aviation magazine or publication, using instead ATC.
• Pilots, air traffic controllers, and other experts will almost always use ATC.
• Many of the expanded acronyms will not fit in the 25 character limit that we have for tag names (FAR, AIM, EASA, etc.).
• If someone doesn't know what ATC stands for, they can simply hover over the tag and it will tell them "Air Traffic Control" (along with other information). Now they even learned (or were at least exposed to) another acronym and will probably recognize it in the future when they see it.
• If we "baby" everyone by not using the acronyms, then we won't be helping them learn and they will be just as lost when reading an aviation article or text somewhere else.
• Also, tag synonyms can be used to catch the people who don't know better and start typing "airtrafficcontrol" or "air-traffic-control".
• If ATC is truly the canonical use (and how folks would likely search), then that's fine - there are always exceptions. It feels generally strange to me to make the expanded text a synonym of an acronym, but if that's what really makes sense for proper taxonomy then .. well .. that's what makes sense :) – Tim Post Dec 30 '13 at 14:54
• @TimPost: Aviation is odd that way, we use acronym's for everything, lol! Your comment brought one question to mind though: Can we not search by a tag synonym? – Lnafziger Dec 30 '13 at 14:57
• I have to check on that, I believe if you search by using [synonym] you'll just search the corresponding real tag. What gets tricky is SEO, as the system automatically places certain (very popular) tags just before the question title in the actual HTML <title></title> block. So, it's kind of a question of do you want titles that say "ATC - {title}" or "Air Traffic Control - {title}". I think in this case either is so canonical that it just boils down to the preference of this particular community. – Tim Post Dec 30 '13 at 15:00
• Totally agree there's no need to baby people by avoiding acronyms. I added an answer expanding on the my position in this case. – Bret Copeland Dec 30 '13 at 21:40

I agree with lnafziger that there are simply too many acronyms and abbreviations in common use to expect to eliminate them. Stack Overflow doesn't use or because no one talks that way... they say SQL or Redis. I think that's well understood, and no one would realistically advocate for tags like or to be spelled out long-form.

The reason I didn't comment on this question initially was because I think ATC is a weird fuzzy area where "air traffic control" is a phrase almost everyone who flies (as a pilot or commercial passenger) knows. So, having a spelled out version I think is appropriate in this case, and the solution of having synonymous with doesn't bother me.

As far as SEO, the spelled out version is probably more helpful since a search for "atc" brings up many results which have nothing to do with aviation. This is going to be true of other tags such as and .

My opinion is that we shouldn't discourage people from using the abbreviated tags, because that's how most people talk. However, where it's practical to have a spelled out version as the canonical form that's a positive. I'm sure anyone who might become a moderator of this site, including myself, would be happy to maintain this mapping.

The abbreviations I think we need to most be on the look out for are any which could have multiple meanings (I can't think of any offhand, but I'm sure there are some) and those which are so specific/localized that only a small percentage of the community would immediately recognize and understand them.
