Boeing 787-9 vs. McDonnell Douglas DC-10-30

The Boeing 787-9 is an extended variant of the 787 Dreamliner series, a family of wide-body, twin-engine jet airliners known for their fuel efficiency and range capabilities. First flown in 2013, the 787-9 was developed to provide additional seating capacity and range compared to its predecessor, the 787-8. This model caters to the needs of airlines for longer routes and increased passenger demand. Out of the 3 787 variants, the -9 is by far the best selling type. As of December 2023, there were 1113 Boeing 787s in airline service, comprising of 397 787-8s, 619 787-9s and 97 787-10s.

The 787-9 spans 62.8 meters (206.1 feet) in length, and 60.1 meters (197.2 feet) in wingspan. The aircraft's use of composite materials, making up a significant portion of its construction, contributes to its lighter weight and structural efficiency, leading to lower fuel consumption and reduced operational costs. Powered by two engine options, either the General Electric GEnx or the Rolls-Royce Trent 1000, the 787-9 delivers a total maximum thrust of 640.0 kN (142,000 lbf). These engines, combined with the aircraft's aerodynamic design, allow it to achieve a range of approximately 14,140 kilometers (7,635 nautical miles). This extended range makes the 787-9 suitable for a variety of long-haul international routes - such as Singapore to San Francisco, Auckland to New York, and Perth to London. These extreme long haul routes can have flight times north of 16 hours.

The aircraft typically accommodates around 290 passengers in a three-class configuration. The cabin features larger windows, higher humidity, and improved air pressure levels compared to traditional airliners. In the commercial aviation market, the Boeing 787-9 competes with other long-range wide-body aircraft such as Airbus' A350-900. Its introduction provided airlines with an option that blends efficiency, capacity, and range, making it a popular choice for various long-haul routes. Airlines that have incorporated the Boeing 787-9 into their fleets include All Nippon Airways, American Airlines, United Airlines, and Air New Zealand. These carriers utilize the aircraft's capabilities to efficiently serve a mix of high-demand routes, taking advantage of its operational efficiency and passenger appeal.

In summary, the Boeing 787-9 stands as a significant development in the Dreamliner series, offering enhanced capabilities in terms of passenger capacity and range. Its design and technological advancements represent an evolution in long-haul air travel, providing airlines with a versatile and efficient aircraft for their long-range operations.

The McDonnel Douglas DC-10-30, is a wide-body trijet airliner designed for long-haul commercial flights. As a member of the DC-10 series, the DC-10-30 was developed to extend the range and capacity of its predecessors, meeting the growing demands of global air travel. The -10-30 was a later, longer range model, and turned out to be the most variant produced. In addition to being a popular passenger aircraft, the DC-10 was also extensively used in the freight industry during its peak.

One of the DC-10's most distinctive features is its three engine configuration, with two engines mounted under the wings and a third engine at the base of the vertical stabilizer. This design was a key differentiator from other wide-body airliners of its time, such as the Boeing 747. The DC-9 made its first flight on August 29, 1970, and was introduced to the commercial aviation market on August 5, 1971 with American Airlines.

Measuring 55.4 meters (181.6 feet) in length, the DC-10-30 was among the larger aircraft of its time, capable of operating on transatlantic and transpacific routes. The aircraft features a wingspan of 50.4 meters (165.3 feet), which supports its long-range flight capabilities and stability at high altitudes. Equipped to hold over 137,500 liters (36,320 US gallons) of fuel, the DC-10-30 was designed for extended range missions, offering a maximum range of 9,600 kilometers (5,184 nautical miles). This capability enabled airlines to operate non-stop intercontinental flights over vast distances. The aircraft's propulsion system consists of 3 GE CF6-50C engines capable of delivering a combined thrust of 680.6 kN (102,000 lbf), providing the power needed for long-haul flights carrying a full complement of passengers and cargo. The DC-10-30's cruise speed of 908 km/h (564 mph) further underscores its efficiency in covering great distances swiftly.

The typical configuration for the DC-10-30 seats up to 270 passengers. Some airliners opted for higher density layouts including 3-4-2, 2-5-2, and 3-3-3. In the market for wide-body aircraft, the McDonnel Douglas DC-10-30 competed with other long-range airliners like the Lockheed L-1011 TriStar and the Boeing 747. The DC-10-30's introduction was a significant contribution to the wide-body aircraft segment, providing airlines with a versatile option for long-haul, high-capacity routes. Prominent operators of the DC-10-30 included airlines such as Continental Airlines, Garuda Indonesia, and Northwest Airlines. Other notable carriers were KLM, British Airways, Iberia, Lufthansa, and Malaysia Airlines.

The McDonnel Douglas DC-10-30's production and operational history reflect its role as a key player in the evolution of long-haul air travel. Its design, performance, and capacity made it a vital asset in the fleets of global airlines, contributing to the expansion and accessibility of international air travel during a critical period of growth in commercial aviation.
