Boeing 747-400 vs. Boeing 787-10

The Boeing 747-400, a major development in the iconic 747 series, debuted in 1988 and quickly became one of the most recognizable aircraft in the world. Known as the "Queen of the Skies," this wide-body airliner redefined long-haul travel with its unparalleled range and capacity.

With a commanding presence, the 747-400 stretches 231.9 feet (70.7 meters) in length and boasts a wingspan of 211.4 feet (64.4 meters). The -400 featured reinvented wingtip extensions and winglets which improved the aircraft's fuel efficiency by 4%. Its distinctive second floor hump and four-engine configuration make it a standout at any airport. The 747-400's design accommodates up to 416 passengers in a typical three-class layout, making it one of the largest passenger airliners at the time of its introduction. The -400 variant was later succeeded by the newer 747-8I.

The 747-400 had three engine options; Pratt & Whitney PW4000s General Electric CF6s, or Rolls-Royce RB211s. Each 747-400 had a thrust of about 56,000 lbf (249.0 kN), summing up to an impressive total of 224,000 lbf (996.0 kN) across the 4 powerplants. This immense power, coupled with a fuel capacity of 57,061 US gallons (216,000 liters), allows the 747-400 to achieve a range of 7,284 nautical miles (13,490 kilometers). This exceptional range capability opened up numerous long-haul and transoceanic routes, reducing the need for stopovers and changing the face of international travel.

In the commercial aviation market, the Boeing 747-400 was a direct competitor to other large aircraft such as the Airbus A340. However, its unique features, like the upper deck and expansive cargo capacity, gave it a special place in the hearts of aviation enthusiasts and professionals alike. The 747-400 was operated by airlines such as British Airways, Qantas, Lufthansa, United Airlines, and Air France. These were among many other operators that used the 747-400 for their flagship international routes. Its spacious cabin and long-range abilities made it ideal for high-profile and high-density routes, offering passengers a unique and comfortable flying experience.

The Boeing 747-400's legacy goes beyond its impressive technical specifications. It symbolizes a significant era in aviation history, where the pursuit of connecting distant parts of the world became a reality. The aircraft's production, which spanned over two decades, is a testament to its enduring appeal and the pivotal role it played in shaping modern air travel. Today, while newer, more fuel-efficient aircraft have started to replace the 747-400, its iconic status and contribution to the airline industry continue to be celebrated. The Boeing 747-400 remains an enduring symbol of the romance and grandeur of flying, representing a bygone era of luxury, scale, and ambition in aviation. Lufthansa, Air China, and Asiana Airlines are some of the last airlines to hold onto their last 747-400s.

The Boeing 787-10 is a wide-body, twin-engine jet airliner designed for medium to long-haul routes. First flown in 2017, the 787-10 is an extension of the Dreamliner series, offering increased capacity and range to meet the evolving needs of the aviation industry.

Measuring 68.3 meters (224.0 feet) in length, the 787-10 is considerably longer than its predecessors, the 787-8 and 787-9. It retains the same wingspan of 60.1 meters (197.2 feet) and wing area of 377.0 square meters (4058.0 square feet). The aircraft's design includes the use of composite materials, which contribute to its lightweight structure and improved fuel efficiency compared to traditional aluminum designs. The 787-10 has two engine options: the General Electric GEnx or the Rolls-Royce Trent 1000. These powerplants produce a total maximum thrust of 680.0 kN (152,000 lbf). Combined with highly innovative aerodynamic design, the -10 can achieve a max range of approximately 6,431 nautical miles (11,910 kilometers).

The 787-10's cabin is designed to accommodate around 330 passengers in a standard three-class layout. In economy, seats are up to 9 abreast, with a 3-3-3 configuration. The aircraft features a passenger-friendly cabin environment with larger windows, improved air quality, and advanced in-flight entertainment systems.

In the commercial aviation market, the Boeing 787-10 has similar capacity to the Airbus A350-900 and Boeing 777-200ER. Its introduction provided airlines with an aircraft that combines operational efficiency with the capacity to serve high-demand routes effectively. In May of 2013, Singapore Airlines became the launch customer, stating they would order 30 787-10s. Other airlines that have included the Boeing 787-10 in their fleets include Singapore Airlines, United Airlines, and Etihad Airways. These carriers utilize the aircraft's capabilities to efficiently serve a mix of international and transcontinental routes.

In summary, the Boeing 787-10 represents a significant development in the Dreamliner series, offering enhanced capabilities in terms of passenger capacity and range. Its design and technological advancements reflect an evolution in long-haul air travel, providing airlines with a versatile and efficient aircraft for their long-range operations. The first -10 was delivered to Singapore Airlines on March 25, 2018. Today, major airlines like United and Air Canada continue to place orders for the 787-10. As older 777-200ERs continue to be retired, airlines may find the 787-10 to be an optimal replacement aircraft.
