Boeing 737 MAX 10 vs. McDonnell Douglas DC-10-30

The Boeing 737 MAX 10 is the largest variant in the 737 MAX series, representing Boeing's expansion of its narrow-body, twin-engine offerings for the commercial aviation market. Launched in 2017, the MAX 10 was developed in response to airlines demanding a larger model than the MAX 9. The announcement for the MAX 10 was quickly followed by 240 orders and commitments from more than ten customers. The United States' aviation regulator, the FAA, cleared Boeing to begin certification flight testing of its 737 MAX 10 in November of 2023. Deliveries are being anticipated for early 2025.

The 737 MAX 10, with its extended fuselage, offers a greater passenger capacity compared to its siblings in the MAX series at 143 feet (43.79 meters). This increase in size allows airlines to accommodate more passengers per flight, optimizing efficiency and profitability, particularly on popular short to medium-haul routes. Equipped with advanced CFM International LEAP-1B engines, the MAX 10 delivers over 58,000 pounds of thrust. The slight stretch of the MAX 10 allows the jet to retain the existing wing design and LEAP engines from the MAX 9, with a trailing-link main landing gear being the only major change.

In the market, the Boeing 737 MAX 10 competes with aircraft like the Airbus A321neo. Both are very similar in terms of seating capacity, and range, but the MAX 10 does fall short in terms of field performance. Boeing predicts that the MAX 10 will yield a 5% lower trip cost and seat cost compared to the A321neo. It provides airlines with an alternative option in the narrow-body segment, offering a balance of capacity, range, and efficiency.

Various airlines have shown interest in the 737 MAX 10 for its ability to meet the demands of modern air travel. It is expected that United Airlines, Korean Air, Alaska Airlines, and Ryanair will have some of the largest fleets of MAX 10s. The MAX 10's capabilities make it an attractive choice for carriers looking to expand their network and serve densely populated routes efficiently.

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.
