De Havilland Canada DHC-7
"Dash 7" passenger 1975
Short/medium range passenger plane with STOL capability. The first prototype flew on March 27, 1975. By 1988 a total of 113 aircraft were built. The Dash 7 (or DHC7) was designed as a STOL (short takeoff and landing) 50 seat regional airliner capable of operating from fields as short as 3,000 ft. in length. Double slotted trailing edge flaps run the entire span of the high mounted wing, increasing the lifting surface. Extra lift is also generated by the airflow over the wing generated by the relatively slow-turning propellers. The standard passenger carrying Dash 7 is the -100, also offered in freighter form as the -101. The only major variant of the Dash 7 was the -150 (and -151 freighter), which featured a higher max takeoff weight and greater fuel capacity, increasing range. Production of the Dash 7 ended in 1988, following Boeing's takeover of de Havilland Canada.
