The 747-400 incorporates major aerodynamic improvements over earlier 747 models, including the addition of winglets to reduce drag, new avionics, a new flight deck and the latest in-flight entertainment systems. The 747-300 three-crew analog cockpit was transformed into a fully digital, two-crew flight deck with cathode ray tube (CRT) displays. Six 8x8-inch (200 x 200 mm) CRTs are used to display airplane flight control, navigation, engine and crew-alerting functions.
