The Bombardier Dash 8 or Q Series, previously known as the de Havilland Canada Dash 8 or DHC-8, is a series of twin-engined, medium range, turbopropairliners. Introduced by de Havilland Canada (DHC) in 1984, they are now produced by Bombardier Aerospace. Over 1,000 Dash 8s of all models have been built, with Bombardier forecasting a total production run of 1,192 units of all variants through to 2016.
The Dash 8 was developed from the de Havilland Canada Dash 7, which featured extreme short take-off and landing (STOL) performance. DHC focused on making the Dash 8 have better cruise performance and lower operational costs. The engine chosen was the Pratt & Whitney Canada PW100. The aircraft has been delivered in four series; the Series 100 was has a typical seating of 37, with the Series 200 delivered with more powerful engines from 1995. The Series 300 is a stretched, 50-seat version first delivered in 1989, and the Series 400 is further stretched to 78 passengers, first delivered in 1999. Models delivered after 1997 has cabin noise suppression and are designated Q. Production of the Series 100 ceased in 2005, and the Q200 and Q300 in 2009. Bombardier is considering launching a stretched version of the Q400.
Q400X
Bombardier is studying development of a 90- to 100-seat stretch of the Q400 with two plug-in segments, currently called the Q400X project. In response to this project, ATR is also studying a 90-seat stretch.
On June 15, 2009, Bombardier commercial aircraft president Gary Scott indicated that the Q400X will be "definitely part of our future" for possible introduction in 2013-14, although he has not detailed the size of the proposed version or committed to an introduction date.
