I think you mean DCA. IAD is still listed as "coming soon" on the PreCheck page on TSA.gov, and there's a big PreCheck booth upstairs near the security checkpoint escalators hyping how great it will be once they get it. Last I read, they were supposed to open at the end of September or early October, but it wasn't active yet on 10/6 when I went through IAD.
