The Bombardier Dash-8 Q400 (Q400) is a high-speed turboprop regional airliner developed by the Canadian aircraft manufacturer Bombardier Aerospace. As the largest and fastest model in the Dash-8 series, the Q400 is known for its advanced noise reduction system, indicated by the "Q" in its designation. It is designed for short to medium-haul regional flights.

Purpose of Development and History

The Q400 was developed in the late 1990s, following the success of previous models in the Dash-8 series. Its primary goal was to offer a solution that brought the low operating costs of turboprop aircraft closer to the speed of jet aircraft. The airplane was designed to provide higher capacity and speed to meet the increasing passenger demand within regional airline networks. It performed its first flight in 1998 and entered commercial service in 2000.

Design and Technical Specifications

The Bombardier Dash-8 Q400 has specific technical specifications and design elements:

• Engines: The aircraft is powered by two Pratt & Whitney Canada PW150A turboprop engines. These engines are designed to provide high performance and efficiency.
• Propellers: It uses large, six-bladed Dowty R408 propellers.
• Passenger Capacity: It typically has a passenger capacity of 70 to 90 passengers.
• Speed: Its maximum cruising speed is approximately 667 km/s (360 knots), which makes it faster than other turboprop aircraft and allows it to perform close to jet speeds.
• Range: Its range is approximately 2,000 km (1,090 nautical miles), making it suitable for use on short and medium-haul routes.
• Dimensions: It is approximately 32.8 meters long, has a 28.4-meter wingspan, and is 8.4 meters high.
• Noise Reduction: The "Q" in its designation refers to the Active Noise and Vibration Suppression (ANVS) system. This system aims to reduce cabin noise levels to enhance passenger comfort.
• Avionics: It features a modern glass cockpit and digital flight control systems.

Operators and Areas of Use

The Dash-8 Q400 is used by many regional and national airlines worldwide. Significant operators include companies such as Austrian Airlines. The aircraft is widely preferred, especially on high-frequency, short and medium-haul routes, as well as for intercity and regional connecting flights. Its turboprop design allows it to operate on shorter runways, facilitating access to regional airports.
