Airbus A340-200 vs. McDonnell Douglas DC-9-30

The Airbus A340-200 is a long-range, wide-body aircraft, part of the A340 family known for its four-engine configuration. Introduced in 1992, the quadjet was designed to meet the demands of long-haul flights. The A340-200 has a longer wingspan (60.3 meters) than length (59.4 meters). The -200 version of the A340 has typical seating capacity for 250 passengers in a standard layout and a maximum capacity of 420 passengers.

Equipped with four engines that provide 136,000 pounds of thrust (600 kN), the A340-200 is recognized for its ability to cover significant distances, with a range of 6,695 nautical miles (12,400 kilometers). The aircraft's fuel capacity of 155,040 liters (40,957 US gallons) contributes to its long-range capabilities, making it suitable for routes such as transatlantic and transpacific flights. The aircraft's spacious cabin offers comfort for passengers on long-haul journeys, and its four-engine design provides additional reliability over vast oceanic and remote areas.

Competing with models like the Boeing 777-200ER, the A340-200 offered airlines a long-range option with a unique four-engine configuration. Its role in commercial aviation has been defined by its capacity to serve long-distance routes with a medium passenger load, meeting the needs of airlines for intercontinental travel.

The Airbus A340-200 has been operated by airlines such as Lufthansa and Air France, serving as a key component in their long-haul fleets. Only a small number of the -200 remain in service today. Additionally, it turned out that the -300 and -600 versions of the A340 were much more popular.

The McDonnel Douglas DC-9-30, a narrow-body jet airliner first introduced in 1966, stands as a significant aircraft in the evolution of commercial aviation. Designed during an era of rapid growth in air travel, the DC-9-30 was developed to meet the demands of short to medium-haul routes, offering airlines a more efficient and practical alternative to the larger jetliners of the time. The Series 30 of the DC-9 included four main sub-variants, -31, -32, -33, and -34. During its production, the -30 was by far the most popular model of the DC-9 with 585 units delivered.

This aircraft was initially developed as the Douglas DC-9, prior to August 1967 merger with McDonnell Aircraft. The DC-9-30 measures in at 36.4 meters (119.3 feet) in length. This size enabled it to operate efficiently in smaller airports and on shorter runways - a niche that was underserved at the time of its introduction. Powered by a pair of Pratt & Whitney PWJTD engines, the DC-9-30 has a total thrust output of 134.0 kN (30,000 lbf). Its fuel capacity of 13,900 liters (3,672 US gallons) gives the DC-9-30 a range of approximately 2,800 kilometers (1,512 nautical miles). This range was particularly advantageous for airlines looking to serve regional networks with an efficient and reliable jet.

The DC-9-30's typical five abreast seating layout can fit around 115 passengers, with a maximum of 127 in a high-density layout.

In its market segment, the McDonnel Douglas DC-9-30 was a key competitor to other short-haul aircraft of the era. Its introduction provided airlines with a jetliner that was not only smaller and more versatile than the larger, long-haul aircraft but also more efficient and economical for short to medium-range routes.

Airlines such as Delta Air Lines, Eastern Air Lines, and TWA were prominent operators of the DC-9-30, utilizing its capabilities to enhance their regional route networks. The aircraft's role in these fleets demonstrated its effectiveness in bridging the gap between propeller-driven airliners and larger jets, contributing significantly to the growth of regional air travel.

The McDonnel Douglas DC-9-30's production and service history highlight its importance as a practical and versatile aircraft in commercial aviation. The last DC-9 to ever be built was delivered in 1982. After its retirement, McDonnell Douglas went on to produce the MD-80 and the MD-95.
