De Havilland Dash 7

The de Havilland Canada Dash 7 was constructed as an aircraft for extremely short runways in difficult terrain. The development was supported by the Canadian government. First prototypes flew in 1975, the serial version started in 1977 for the first time and in 1978 the first aircraft could be delivered to Rocky Mountain Airways.

The Dash 7 is able to take off with 50 passengers on board from an only 700 metres long runway. This is made possible by four engines, a clever wing construction, as well as by powerful brakes and spoilers. The Dash 7 is also able to approach with an angle of 6.2°, what enables serving airfields within mountaneous sourrounding. The four Pratt&Whitney PT6 engines have the advantage of being extremely silent.

According to the serie -100 the series -101 (cargo version) as well as series -150/151 with increased takeoff weight were produced. Though the Dash 7 has excellent qualities, the prdoduction was less than expected. When the production was stopped in 1988, only 113 Dash 7 were built.
