Category talk:Aviation articles needing infoboxes

Subcategories
Are the subcategories of this category needed? They don't seem to be used. I haven't seen any of them populated when I've visited the site. Contrast with the general category with over 1,000 pages. The category seems to be primarily populated by the template for Wiki Project Aviation, which contains a "needs infobox=yes" (by default? About 1/3 to 1/2 of the pages I've visited to add infoboxes already had one). --Lineagegeek (talk) 13:49, 29 August 2014 (UTC)
