ATR 72-600 vs. Bombardier Q400 (Dash 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 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.
