Overview
The de Havilland Canada DHC-8, popularly known as the Dash 8, is a series of twin-turboprop airliners designed by de Havilland Canada in the early 1980s. They are now produced by Bombardier Aerospace which purchased DHC from Boeing in 1992. Since 1996, the aircraft have been known as the Q Series, for "quiet" due to installation of the Active Noise and Vibration Suppression (ANVS) system designed to reduce cabin noise and vibration levels to nearly those of jet airliners.
Distinguishing features of the Dash 8 design are the large T-tail intended to keep the tail free of propwash during takeoff, a very high aspect ratio wing, the elongated engine nacelles also holding the rearward-folding landing gear and the pointed nose profile. First flight was on 20 June 1983, while the airliner entered service in 1984 with NorOntair. Piedmont Airlines, formerly known as Henson Airlines, was the US launch customer for the Dash 8 in 1984.
The Dash 8 design had better cruise performance than the earlier Dash 7, was less expensive to operate, and more notably, much less expensive to maintain. The Dash 8 had the lowest cost per passenger mile of any feederliner of the era. The main disadvantage compared to the earlier Dash 7 was somewhat higher noise levels, but only in comparison, as the Dash 7 was notable in the industry for extremely low noise due to its four very large and slow-turning propellers. The Dash 8 also could not match the superb STOL performance of its earlier DHC forebears.
The Q400 is an extraordinary modern technology turboprop, offering airlines exceptional economics with jet speed and comfort in the 70 seat market. Designed to meet the requirements of regional airlines for more seats, superior economics and greater speed in the high-density regional arena, the Q400 is also replacing and supplementing jets on many regional and mainline routes worldwide.
With a maximum cruise speed of 360 kts, outstanding performance and seating of up to 78 passengers, the Q400 provides airlines with greater revenue-generating opportunities in regional and low cost markets and extends an airline's reach well beyond traditional turboprop markets. The Q400 is easily as fast as most jets on airline routes under 500 miles (800 km) and it’s extraordinary economics, best of any regional aircraft today, are enabling it to compete effectively against established low cost carriers.
While the Q400 is larger and faster than the other Q Series models, this aircraft can be flown by the same pool of pilots, resulting in reduced crew costs for airlines with a mixed Q Series fleet.
