Indicator, Attitude Director (ADI), Shuttle, Columbia

This attitude-director indicator (ADI) instrument was removed from the Space Shuttle Columbia during its upgrade to an electronic "glass cockpit" in 2000. The instrument gave the crew attitude information as well as attitude rate and attitude errors. The orbiter's attitude was displayed on an enclosed ball ("eight ball") that was gimbaled and marked with numbers indicating angles. The ball moved in response to software-generated inputs to depict the orbiter's attitude in pitch, yaw and roll.NASA transferred the set of Columbia's old cockpit instruments to the Museum in 2005.
