Bombardier Dash-8 Q400

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

The Q400 was developed in the late 1990s following the success of earlier models in the Dash-8 series. Its primary objective was to provide a solution that combined the low operating costs of turboprop aircraft with speeds approaching those of jet aircraft. The aircraft was designed to offer higher capacity and speed to meet growing passenger demand on regional air networks. It made its first flight in 1998 and entered commercial service in 2000.

The Bombardier Dash-8 Q400 features specific technical characteristics and design elements:

• Engines: The aircraft is powered by two Pratt & Whitney Canada PW150A turboprop engines, designed to deliver high performance and efficiency.
• Propellers: It uses large six-bladed Dowty R408 propellers.
• Passenger Capacity: It typically has a capacity of 70 to 90 passengers.
• Speed: Its maximum cruising speed is approximately 667 km/h (360 knots), making it faster than other turboprop aircraft and offering performance close to that of jet aircraft.
• Range: Its range is approximately 2,000 km (1,090 nautical miles), making it suitable for short- and medium-range routes.
• Dimensions: It is approximately 32.8 meters in length, with a wingspan of 28.4 meters and a height of 8.4 meters.
• Noise Reduction: The letter "Q" refers to the Active Noise and Vibration Suppression (ANVS) system. This system aims to improve passenger comfort by reducing cabin noise levels.
• Avionics: It features a modern glass cockpit and digital flight control systems.

The Dash-8 Q400 is operated by numerous regional and national airlines worldwide. Major operators include Austrian Airlines. The aircraft is widely preferred for high-frequency short- and medium-range routes, particularly for intercity and regional connectivity flights. Its turboprop design enables operations on shorter runways, facilitating access to regional airports.
