context_page_description: The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the de Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. Three sizes were offered: initially the 37–40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the 68–90 seats -400 from 1999, still in production. The Q Series are post-1997 variants fitted with active noise control systems.
context_section_description: The Series 400 introduced an even longer airframe that was stretched 6.83 metres (22.4 ft) over the Series 300 (10.26 metres (33.7 ft) over the Series 100/200), has a larger, stouter T-tail and has a passenger capacity of 68–90. The Series 400 uses Pratt & Whitney Canada PW150A engines rated at 4,850 shp (3,620 kW). The aircraft has a cruise speed of 360 knots (667 km/h), which is 60–90 knots (111–166 km/h) higher than its predecessors. The maximum operating altitude is 25,000 ft (7,600 m) for the standard version, although a version with drop-down oxygen masks is offered, which increases maximum operating altitude to 27,000 ft (8,200 m).
  Between its service entry in 2000 and the 2018 sale to Longview/Viking, 585 have been delivered at a rate of 30-35 per year, leaving a backlog of 65, for a market value at a stable level of $21 million new.
