Boeing 747-400
The Boeing 747-400 was an advanced development of the iconic 747 "Jumbo Jet," entering service in 1989. It was designed to fly farther and carry passengers more economically than earlier 747 models while burning less fuel per seat.
Among its most visible changes were extended wings fitted with upturned winglets, which reduced aerodynamic drag and improved range. Inside, the aircraft adopted a modern two-crew glass cockpit, eliminating the flight engineer's station that earlier 747s had required and relying on electronic displays and automated systems.
With its long range and high capacity, the 747-400 became the dominant long-haul airliner of the 1990s, the backbone of intercontinental fleets for carriers around the world. It was the best-selling version of the 747 and helped extend the life of the venerable design well into the twenty-first century.
