The essential components of the AI include a symbolic miniature aircraft mounted so that it appears to be flying relative to the horizon. An adjustment knob, to account for the pilot's line of vision, moves the aircraft up and down to align it against the horizon bar. The top half of the instrument is blue to represent the sky, while the bottom half is brown to represent the ground. The bank index at the top shows the aircraft angle of bank. Reference lines in the middle indicate the degree of pitch, up or down, relative to the horizon.<ref name=FAA1/><ref name=FAA2/>

Most Russian-built aircraft have a somewhat different design. The background display is colored as in a Western instrument, but moves up and down only to indicate pitch. A symbol representing the aircraft (which is fixed in a Western instrument) rolls left or right to indicate bank angle.<ref>{{citation|last=Learmount|first=David |title=Which way is up for Eastern and Western artificial horizons? |url=http://www.flightglobal.com/blogs/learmount/2009/02/which_way_is_up_for_eastern_an/ |work=flightglobal.com |date=2009-02-09 |url-status=dead |archive-url=https://web.archive.org/web/20141029214654/http://www.flightglobal.com/blogs/learmount/2009/02/which_way_is_up_for_eastern_an/ |archive-date=October 29, 2014 }}</ref> A proposed hybrid version of the Western and Russian systems would be more intuitive, but has never caught on.<ref>[https://web.archive.org/web/20130625220312/http://www.flightglobal.com/news/articles/safety-expert-proposes-low-cost-loss-of-control-fixes-353929 Safety expert proposes low-cost loss of control fixes ], [[FlightGlobal]], 2011-03-04</ref>
