Boeing 717-200 vs. Bombardier Q400 (Dash 8)

The Boeing 717-200 is a narrow-body, twin-engine jetliner designed for regional and short to medium-haul routes. Characterized by its efficiency and operational flexibility, it caters to airlines requiring a reliable and cost-effective solution for less dense routes. Developed as a part of the Boeing family, the 717-200 first entered service in 1998, marking Boeing's entry into the regional jet market. It was produced until 2006, with a focus on meeting the specific demands of regional air travel. The aircraft's production history reflects Boeing's strategy to offer a range of jetliners tailored to various market segments.

With dimensions of 37.8 meters (124.0 feet) in length and a wingspan of 28.5 meters (93.3 feet), the 717-200 is ideally sized for operations at smaller airports. It typically accommodates 110 passengers, providing a comfortable and efficient travel experience on regional journeys. Powered by two rear-mounted Rolls-Royce BR715 engines, the Boeing 717-200 delivers a total thrust of 190.0 kN (42,800 lbf). Its fuel capacity of 16,670 liters (4,404 US gallons) supports a range of 3,815 kilometers (2,060 nautical miles), making it suitable for various regional routes. The aircraft has a cruise speed of 822 km/h (511 mph).

In the competitive regional jet market, the Boeing 717-200 stands as a contender against models like the Bombardier CRJ Series and Embraer E-Jets. Its introduction provided airlines with a practical and economical option for regional networks, balancing the needs for capacity, range, and cost-efficiency. Airlines such as Delta Air Lines, Hawaiian Airlines, and QantasLink have utilized the 717-200 for its operational efficiency and adaptability. Not many 717s are still in service today. Delta is one of the last airlines to be phasing out its own fleet.

The Boeing 717-200's legacy in commercial aviation is defined by its role in regional air travel. While its production has concluded, the 717-200 continues to be recognized for its contribution to the regional aviation segment.

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.
