An attitude indicator (AI), also known as gyro horizon or artificial horizon or attitude director indicator (ADI), is an instrument used in an aircraft to inform the pilot of the orientation of the aircraft relative to earth. It indicates pitch (fore and aft tilt) and bank or roll (side to side tilt) and is a primary instrument for flight in instrument meteorological conditions. Attitude indicators also have significant application under visual flight rules, though some light aircraft do not have them installed.

—John Ashbery (b. 1927)
