Use for questions regarding specifics of any aircraft in the de Havilland Canada / Bombardier Dash 8 series (also known as the DHC-8 or Q-series).
The Dash 8 (officially the DHC-8) is a series of regional airliners originally built by de Havilland Canada. They are powered by two Pratt & Whitney PW100-series turboprop engines. From 1992 to 2019, the aircraft were built by bombardier, and, since then, the newly formed company De Havilland Aircraft Co. of Canada has taken over production.
Four variants have been built:
- The Series 100 was the first variant (entering service in 1984), and has a passenger capacity of 37 to 40 seats; unlike the later variants, no Q-version was ever offered for the Series 100. Production of the Series 100 ended in 2005 after building 299 aircraft.
- The Series 200, introduced in 1995, has the same length and capacity as the Series 100, but the more powerful engines of the Series 300 (albeit running at a slightly lower thrust rating) - which it postdates, despite its lower version number - resulting in improved aircraft-performance. 105 Series 200s were built before production ended in 2009.
- The Series 300 was introduced in 1989, with a stretched cabin (along with more powerful engines to power the bigger, heavier aircraft) which increased its capacity to 50 to 56 seats. The last Series 300, #267, was delivered in 2009.
- The Series 400 was introduced in 1999, with an even-further-stretched cabin (making it more than twice as long as the Series 100 and 200), a larger tail, much-more-powerful engines, and a capacity of 68 to 90 seats. 587 Series 400s have been delivered as of March 2019; the Series 400 is the only Dash 8 version still in production, with 58 unfilled orders.
Since mid-1996, an active noise-reduction and vibration-cancelling system has been installed; these newer, quieter aircraft (including the later Series 200s and 300s, and all Series 400s) are known as the Q-Series (Q200, Q300, and Q400). A total of 1258 aircraft have been delivered as of March 2019.
