Vxworks is typical, but Linux does happen sometimes. Most often for ground stations or auxiliary tools, sometimes for continuity between the development and deployed environment, sometimes because it's just a research project and certification isn't an issue. I wouldn't claim it's common or that you'd be likely to see it in a deployed environment, but it's not totally unheard of. Throw Linux & UAV in Google - you'll see what I mean.
