ATR 72-600 vs. Douglas DC-8

The ATR 72-600, part of the renowned ATR aircraft family, is a twin-engine, high-wing turboprop airliner designed primarily for regional and short-haul flights. First flown in 1988, this model has become a popular choice for airlines operating in small markets.

ATR, the manufacturer of the ATR 72, has produced over 1800 units through 2023. The -600 variant is the latest model to be designed, making its first flight in 2007. Compared to the smaller ATR 42, the ATR 72 has a longer fuselage and wider wingspan. At 27.2 meters (89.1 feet) from nose to tail and a width of 27.1 meters (88.7 feet), the ATR 72-600 is characterized by its compact and efficient design, suitable for operations at smaller airports. It has a max takeoff weight of 23,000 kg (50,706 lbs), and a max payload of 7,400 kg (16,313 lbs). The ATR 72-600 is powered by two engines, delivering a total output of 3692 kW (4,950 shp), providing reliable performance for its operational requirements. It has a fuel capacity of 6,400 liters (1,691 US gallons), which contributes to its range of 1,528 kilometers (825 nautical miles). With a cruise speed of 510 km/h (317 mph), the ATR 72-600 offers an efficient travel option for regional airlines, connecting smaller communities and cities.

In the regional aviation sector, the ATR 72-600 competes with aircraft like the Bombardier Q400 and Embraer E-Jets. Its advantage lies in its operational cost-effectiveness, making it an appealing choice for airlines serving regional routes with moderate passenger volumes. Airlines such as Air New Zealand, IndiGo, SAS, and TAROM operate the ATR 72-600, utilizing its capabilities to serve regional networks. These carriers value the aircraft for its ability to provide efficient, reliable service on shorter routes, which are crucial for maintaining regional connectivity. The introduction of the ATR 72-600 to the market was driven by the need for an economical, versatile aircraft that could effectively serve the regional aviation segment. Its operational role has been defined by its capacity to offer cost-efficient solutions for airlines operating on less dense routes.

Today, the ATR 72-600 remains a significant player in the regional aircraft market, demonstrating its continued relevance in connecting smaller cities and communities.

The Douglas DC-8, is a long-range, narrow-body jet airliner developed by American Douglas Aircraft Company. Introduced in the mid-1960s, the DC-8 was among the first generation of commercial jetliners, marking a significant transition in air travel from propeller-driven to jet-powered aircraft. This model was developed during a period of rapid advancement in aviation technology, driven by the growing demand for faster and more efficient air travel.

The DC-8's design features a length of 57.1 meters (187.3 feet), which, at the time of its introduction, was one of the longest for any airliner. This length, coupled with a wingspan of 45.2 meters (148.4 feet), reflects the aircraft's capacity to handle long-haul routes, a key requirement during the jet age's early years. The DC-8's size was a response to the airline industry's needs for greater passenger capacity and range. Equipped with four Pratt & Whitney JT3D turbojet engines, the DC-8 could achieve a total thrust of 320.0 kN (36,000 lbf). This power output was instrumental in enabling the aircraft to reach a range of approximately 5,900 kilometers (3,186 nautical miles), making it suitable for transcontinental and transatlantic routes. The DC-8's speed and range capabilities were significant advancements at the time, contributing to the reduction of travel times on international routes.

The cabin of the DC-8 was designed to seat around 220 passengers in a typical two-class configuration with six seats across. This capacity allowed airlines to transport more passengers per flight compared to earlier propeller-driven airliners, significantly increasing operational efficiency. The interior of the DC-8 was designed with comfort in mind, offering features that were considered state-of-the-art during its era.

In the commercial aviation market, the Douglas DC-8 competed with the other early quadjet, the Boeing 707. The introduction of the DC-8 was part of the broader trend towards jet-powered air travel, which revolutionized the airline industry by offering faster and more comfortable flights over longer distances. Airlines that operated the DC-8 were United Airlines, Delta Air Lines, Thai Airways, and Pan American World Airways. The DC-8's operational role was marked by its ability to serve long-haul routes with improved efficiency and speed, a factor that contributed significantly to the growth of global air travel during the 1960s and 1970s. The DC-8 was produced until 1972, with 556 aircraft built. As the model aged out, it was superseded by larger wide-body Douglas' DC-10 trijet.
