ATR 42-600 vs. Bombardier Q400 (Dash 8)

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 Bombardier Q400, belonging to the DHC Dash 8 series, is a turboprop aircraft engineered for regional aviation. With a length of 32.9 meters (107.9 feet) and a wingspan of 28.4 meters (93.2 feet), the Q400 is designed to operate efficiently in diverse regional airport environments. It strives in operations that require agility and short takeoff and landing capabilities. From the outside, the Q400 can be identified by its high-wing design, 6-bladed propellors, T-tail, and wing-mounted landing gears. The Q400 was the most popular variant of the Dash 8, with over 600 delivered as of September 2019. De Havilland ultimately paused Dash 8-Q400 production in 2021 due to the pandemic and lack of demand.

Powered by two Pratt & Whitney PW150A engines, the aircraft is capable of producing a substantial power output, . This power enables the Q400 to achieve a range of approximately 2,040 kilometers (1,102 nautical miles), making it a suitable choice for various regional routes, from short hops to more extended connections. The selection of turboprop engines for the Q400 reflects a focus on fuel efficiency and operational cost-effectiveness, key considerations in the regional airline market. The cabin of the Q400, configured to seat about 76 passengers in a standard layout, can be adapted to accommodate up to 90 passengers in high-density seating arrangements. This flexibility allows airlines to optimize the aircraft for different route profiles. The cabin design incorporates elements aimed at improving passenger comfort, such as noise reduction, which is particularly beneficial during the shorter flights typical in regional travel.

In the regional aircraft market, the Bombardier Q400 offers an alternative to similar capacity regional jets, like the ATR 72. The aircraft's competitive edge lies in its combination of turboprop efficiency with a passenger capacity that approaches that of larger regional jets. This balance makes the Q400 a viable option for airlines operating a range of regional routes. Operators of the Q400, including Porter Airlines, Flybe, and Horizon Air, have found the aircraft suitable for their diverse regional networks. The Q400's operational profile allows these airlines to service routes efficiently, connecting smaller cities and towns with major hubs. The aircraft's role in these fleets underscores its suitability for the specific demands of regional air travel, where efficiency, versatility, and cost-effectiveness are paramount.

In summary, the Bombardier Q400's introduction into the regional aviation sector provided airlines with an aircraft that aligns well with the operational requirements of short to medium-haul routes. Its design, capacity, and range capabilities make it a noteworthy choice for airlines looking to enhance their regional operations.
