Embraer E170 vs. Bombardier Q400 (Dash 8)

The Embraer E170, introduced in 2002, is a narrow-body regional jet, and the smallest variant in the Embraer E-Jet family. This aircraft was developed to address the needs of regional airlines for a modern, efficient jet that could operate on short to medium-haul routes with improved economic performance and passenger comfort. The E170 was the first E-Jet to enter revenue service in March 2004. Production was halted in 2017, and there are currently no plans for a newer variant in the E2 generation.

With a length of 29.9 meters (98.1 feet) and a wingspan of 26.0 meters (85.3 feet), the E170 is designed to be agile and efficient in various airport environments, including smaller regional and city airports. With a height of 2.9 meters (9.5 feet), the cabin of the E170 is roomy enough to comfortably stand in the aisle. Powered by General Electric CF34-8Es, the E170 boasts 63.0 kN (14,200 lbf) of thrust per engine. The aircraft has a range of 3,982 kilometers (2,150 nautical miles), making it well-suited for a variety of regional routes. The E170's range and fuel efficiency make it a compelling option for airlines looking to serve regional networks with a cost-effective jet.

The cabin of the E170 is designed to seat around 72 passengers in a standard configuration, with a high-density option allowing for up to 78 passengers. The interior of the E170 is focused on passenger comfort, featuring spacious seating, larger windows, and advanced in-flight entertainment systems. The aircraft's cabin design is also conducive to quick boarding and disembarking, a key factor in maintaining efficient operations on regional routes.

In the regional jet market, the Embraer E170 competes with aircraft such as the Bombardier CRJ-700, Airbus A220, and Bombardier Q400. Its introduction was in line with a growing trend towards regional jets that offer jetliner amenities and performance, combined with the economics and flexibility required for regional airline operations. Airlines that operate the Embraer E170 include LOT Polish Airlines, Republic Airways, and S7 Airlines. These carriers utilize the E170's capabilities to serve a mix of short and medium-range routes, leveraging its efficiency, range, and passenger appeal. The aircraft's operational profile allows these airlines to effectively connect smaller cities with major hubs and offer comfortable travel experiences on regional routes.

In summary, the Embraer E170's introduction into the regional aviation sector provided airlines with an aircraft that aligns well with the operational requirements of regional routes. Its design, passenger capacity, and range capabilities make it a notable choice for airlines looking to enhance their regional operations with an efficient, modern jet.

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.
