ATR 42-600 vs. McDonnell Douglas DC-9-30

The ATR 42-600 is a twin-engine, turboprop aircraft is designed for regional travel. Its role in the aviation industry focuses on connecting regional and remote areas, making air travel accessible to smaller communities. The ATR 42 is most recognizable by its high-wing design , T-tail, and propeller engines.

The ATR 42 was originally introduced in 1984, with the -600 variant beginning flight in 2010. The -600 comes in at 22.7 meters (74.4 feet) long with a wingspan of 24.6 meters (80.6 feet). Its wing area of 54.5 square meters (586.6 square feet) is designed to provide efficient lift for short-runway takeoffs and landings. With a typical seating arrangement for 44 passengers, the ATR 42-600 is an optimal choice for airlines serving regional routes with lower passenger volumes. Powered by two Pratt & Whitney Canada PW120s, the aircraft delivers a total output of 3222 kW (4,320 shp), ensuring reliable performance for its operational requirements. The ATR 42-600 has a fuel capacity of 5,730 liters (1,514 US gallons), contributing to its range of 1,326 kilometers (716 nautical miles). Its cruise speed of 556 km/h (345 mph) enables efficient travel times for regional connections.

In the competitive landscape of regional aviation, the ATR 42-600 contends with aircraft like the Bombardier Q400, Fokker 50, an Embraer EMB 120 Brasilia. Its appeal lies in its operational efficiency and suitability for short-haul routes, particularly in regions where larger jet aircraft are not viable. Airlines that have integrated the ATR 42-600 into their fleets include Silver Airways and Logan Air. These carriers utilize the aircraft to serve regional networks, capitalizing on its capacity to operate efficiently on shorter routes and provide essential connectivity.

The development of the ATR 42-600 was driven by the growing need for efficient, reliable aircraft in the regional market. Its introduction into service has been instrumental in expanding the reach of air travel to smaller markets, underscoring the importance of regional connectivity in the broader aviation industry.

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.
