Despite being out of production for some years now the four engine de Havilland Canada Dash 7 remains unrivalled because of its impressive STOL and low noise capabilities.

The Dash 7 (or DHC7) was designed as a STOL (short takeoff and landing) 50 seat regional airliner capable of operating from strips as short as 915m (3000ft) in length. The main design features to achieve such a capability were an advanced wing and four Pratt & Whitney PT6A turboprops. Double slotted trailing edge flaps run the entire span of the high mounted wing dramatically increasing the lifting surface available for takeoff.
