NASA Space Shuttle Attitude Ball

Thanks for the lesson. I always wondered how the, "eight ball" worked in a space craft.

One other thing, the black/white COULD be used to represent sky/ground - in the local vertical/local horizontal mode it would behave just like an artificial horizon in an airplane representing the shuttles pitch, roll and yaw relative to earths surface, but it could also display relative to a static inertial reference frame and remain fixed to one point in space, as well as a pilot selected reference frame such as relative to the ISS

Thanks again!

If you want to own one that's almost identical, keep an eye out for an aru-11/a (aka f4 phantom attitude indicator) - they pop up on eBay for a few hundred every now and then. The ARU-11/a was made by Lear Seigler and used almost unmodified as the Gemini FADI and is one of the few airplane attitude indicators that used a 360° ball. The lunar module FDAI was derived from it, and that model was then used with slight changes for the original shuttle ADI's
