History
Bombardier's de Havilland Dash 8 has proven to be a popular player in the regional turboprop airliner market. De Havilland Canada began development of the Dash 8 in the late 1970s in response to what it saw as a considerable market demand for a new generation 30 to 40 seat commuter airliner. The first flight of the first of two preproduction aircraft was on June 20 1983, while Canadian certification was awarded on September 28 1984. The first customer delivery was to norOntair of Canada on October 23 1984. Like the Dash 7, the Dash 8 features a high mounted wing and Ttail, and has an advanced flight control system and large full length trailing edge flaps. Power meanwhile is supplied by two Pratt & Whitney Canada PW120 series (originally designated PT7A) turboprops. Initial Dash 8 production was of the Series 100, which was followed by the Series 100A in 1990. The 100A introduced a revised interior with extra headroom and PW120A turboprops. The Series 100B was offered from 1992 with more powerful PW121s for better climb and airfield performance. Production since switched to the improved performance Dash 8-200. Announced in 1992 and delivered from April 1995 the -200 features more powerful PW123C engines which give a 56km/h (30kt) increase in cruising speed, as well as greater commonality with the stretched Dash 8300. The 200B derivative has PW123Bs for better hot and high performance. From the second quarter of 1996 all Dash 8s delivered have been fitted with a computer controlled noise and vibration suppression system (or NVS). To reflect this the designation was changed to Dash 8Q (Q for `quiet'). In 1998 that was changed again to Dash 8 Q200 when a new interior was introduced.

History
With the success of the Dash 8-100 series, a stretched version with greater capacity was a logical development. De Havilland Canada (now part of Bombardier) launched full scale development of a 50 seat stretched version of its Dash 8 regional airliner during 1986, approximately two years after the standard fuselage length aircraft had entered service. The first series 300 aircraft was in fact the prototype Dash 8 converted to the new length, and it flew for the first time in its new configuration on May 15 1987. Flight testing culminated in the awarding of Canadian certification in February 1989, with the first delivery to Time Air following late that same month. US certification was awarded in June 1989. The stretch comprises fuselage plugs forward and aft of the wing, increasing length by 3.43m (11ft 3in). In addition, the wings are greater in span. The fuselage stretch increases typical seating capacity to 50 (at 81cm/32in pitch), or for up to 56 (at 74cm/29in pitch). Other changes compared with the Dash 8-100 were minor, but included a larger, repositioned galley, larger toilet, additional wardrobe, dual air conditioning packs, a new galley service door and optional APU. The Dash 8-300 has been offered in a number of variants. The standard 300 was followed in 1990 by the 300A which introduced optional higher gross weights, interior improvements (as on the Dash 8-100A), and standard PW123A engines (with PW123Bs optional). The 300B was introduced in 1992 and has 1865kW (2500shp) PW123Bs as standard, as is the optional high gross weight of the 300A. The 300E has 1775kW (2380shp) PW123Es rated to 40 degrees, thus improving hot and high performance. Like the Dash 8Q-200, all Dash 8-300s built since the second quarter of 1996 have been fitted with a computer controlled noise and vibration suppression system (or NVS) and so from then all models were designated Dash 8Q-300s. In 1998 the aircraft was again renamed, this time to Dash 8-Q300 when a new interior was also introduced.
