About the Boeing 737-400

The Boeing 737-400, part of the 737 Classic series, is a narrow-body, twin-engine airliner developed to meet the evolving requirements of the short to medium-haul market. First introduced in 1988, the 737-400 expanded upon the success of its predecessor, the 737-300. The -400 variant entered manufacturing shortly after finalization of design plans between Boeing and launch customer Piedmont Airlines (later merged into US Airways). It gives increased capacity and range, offering an option in between Boeing's 737-300 and the 757-200.

The fuselage incorporated a key 8 foot expansion to enable typical accommodation for up to 170 passengers in a 2-class layout. Other changes included increased weights and structural reinforcements, enhanced avionics/flight controls, and higher thrust CFM powerplants required for the heavier max takeoff figures. Cost efficiencies were achieved keeping cockpit continuity with the ubiquitous 737 flight deck suite.

Spanning 119.6 feet (36.5 meters) in length with a wingspan of 94.5 feet (28.8 meters), the 737-400 was designed to accommodate the growing demand for larger single-aisle aircraft. The aircraft typically seats 144 passengers, providing more space and comfort compared to earlier models in the series. This increased capacity made the 737-400 an attractive option for airlines seeking to transport more passengers on popular routes, without the need for a larger, wide-body aircraft. Equipped with two CFM International CFM56-3C1 engines, the 737-400 delivers a total thrust of 44,000 lbf (196.0 kN). This engine configuration, combined with a fuel capacity of 5,310 US gallons (20,100 liters), allows the aircraft to achieve a range of 2,079 nautical miles (3,850 kilometers).

In the competitive commercial aviation market of its time, the Boeing 737-400 contended with models like the McDonnell Douglas MD-80 series. Its introduction marked another milestone for Boeing in the evolution of the 737 family, solidifying the company's position in the market for short to medium-haul airliners. Airlines such as Alaska Airlines, Turkish Airlines, and British Airways incorporated the Boeing 737-400 into their fleets. The aircraft's operational role was significant, enabling these carriers to expand their route networks and increase flight frequencies, particularly in domestic and regional markets.

About the Boeing 787-10

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.
