This short article came across my newfeed: https://www.avweb.com/avwebflash/news/Cessna-Will-Offer-Epic-Optixs-Low-Cost-HUD-230669-1.html So it would seem since this is a portable, that Cessna will just sell it at a discount but it is not installed, certified equipment? So what is the potential value of a non-certified HUD to a GA VFR pilot? How about IFR pilot? I'm guessing it needs Foreflight but not sure. Too bad it so large looking. When I think of HUD's they seem rather small and unobtrustive but I supposed all the other parts are probably down below the dash.
