The Dash 8 “Q400” is a series of twin-engine, medium-range, turboprop regional airliners. The
aircraft was introduced by de Havilland Canada (DHC) in 1984. Originally named the DHC-8
(nicknamed “Dash 8”), the aircraft started as the -100 series, then the -200 series, the -300
series and finally the -400 series. They are now produced by Bombardier Aerospace. De
Havilland Canada was sold to Boeing in 1986, but then re-sold to Montreal-based Bombardier
Aerospace in 1992. This acquisition was done in the midst of Bombardier’s expansion of the late
80’s; it had acquired Canadair in 1986, Short Brothers in 1989 and then Learjet as well in 1990.
The Dash 8 was developed from the de Havilland Canada Dash 7, which featured extreme short
take-off and landing (STOL) performance. With the Dash 8, DHC focused on improving cruise
performance and lowering operational costs. The engine chosen was the Pratt & Whitney
Canada PW100. The aircraft has been delivered in four series. The Series 100 has a maximum
capacity of 39, the Series 200 has the same capacity but offers more powerful engines, the
Series 300 is a stretched, 50-seat version, and the Series 400 is further stretched to 78
passengers. Over 1,000 Dash 8s of all models have been built.
The DHC-8-400 “Q400” is a stretched and improved version of the Dash 8 that entered service
in 2000. It is equipped with an ANVS system (Active Noise and Vibration Suppression). Models
delivered after 1997 have cabin noise suppression and are designated with the prefix "Q“, as in
“Q400”. Its 360 knot (667 km/h) cruise speed is 60–90 knots (111–166 km/h) higher than its
competitors and predecessors. Powered by PW150A engines rated at 5,071 shp (3,781 kW) at
maximum power (4,850 shp or 3,620 kW maximum continuous rated). The maximum operating
altitude is 25,000 ft (7,600 m) for the standard version. Production of the Series 100 ceased in
2005, and the Q200 and Q300 in 2009.
The Q400 has been through two company acquisitions, one of which was near fatal. The
engineers who worked on this airframe are very proud of its rich history and know all too well
the challenges of stretching the airframe and stretching a shrinking budget. We have to
remember that this started as a bush flying aircraft that has been marketed to compete with
jets. The aircraft is incredibly diverse being able to serve in high end commuter markets, to
military platforms and even as a water bomber. This is an aircraft that has adapted to changing
economic times and kept a great safety rating.
This is an aircraft designed to operate in the harsh canadian winter and difficult weather
conditions that you will have to fly into without expensive automation systems: there is no
auto-throttle nor auto-land system. The approaches need to be planned very carefully and most
of your landings will be quite “firm” because of the landing gear’s configuration. Give it a
chance and I am sure that you will enjoy its superbly simulated systems. Great job, Majestic
Software!
