For questions about words, phrases, and definitions that are specific to aviation or used in a different way in aviation. (Questions about standard words, phrases, and abbreviations used by pilots and ATC specifically in radio transmissions should usually use the [phraseology] tag instead.)
Use this tag for any questions about words, phrases, and definitions that are specific to aviation or used in a different way in aviation. If possible, add other tags to indicate the general subject area.
(If you have a question about terminology used by pilots and ATC in radio transmissions, then you should usually use the phraseology or radio-communications tags instead, but using terminology is still fine if you aren't sure.)
