New systems, such as a “glass cockpit”, flight management computers, and new engines allowed it to be flown with a crew of just two pilots, and the position of Flight Engineer became unnecessary. It had many structural and electronics improvements over the earlier models, which had debuted 18 years earlier. The 747-400 was a major development of the 747 series.
