Provenance In the all-digital flight deck of the Boeing 767-200, Delta's first Boeing 767, six of these digital screens displayed data as needed from 140 microprocessors and computers that regulated and monitored the jet's flight, comfort, and safety systems. Even though most of the information needed by the crew was shown on the electronic screens, the backup electromechanical instruments still filled the remaining space on the instrument panels in the aircraft. Delta flew the 767-200 from 1982-2006.

The original Boeing 767 was the first Boeing widebody jet with a two-crew "glass cockpit." The new electronics replaced the role of the flight engineer, as the pilot and co-pilot could now directly monitor the aircraft systems. Computer software also allowed easy updates, rather than time-consuming mechanical overhauls to each aircraft. The new computerized systems, along with an improved wing and use of lighter composite materials, contributed to the 767's lower fuel consumption, which was 30 percent better than the older aircraft it replaced.
