.

The de Havilland Canada company felt they could compete with these designs in a roundabout way. With their excellent STOL performance, their designs could fly into smaller airports more centrally located in city centres, with runways that the other aircraft could not easily use. The original specification called for a 40-passenger aircraft with a fairly short range of 200 statute miles, operating from runways only 2000 ft (609.6 m).

With new noise restrictions coming into effect throughout the 1970s, an aircraft tailored for this role would also have to be very quiet. To meet this restriction, the new design used oversized propellers geared to spin at a slower speed than normal; much of the sound from a propeller is generated at the tips which are spinning near the speed of sound, and therefore, by reducing the number of RPM, this noise is reduced substantially. The Dash 7 often landed with only 900 rpm, and took off at only 1,210.

In other respects, the new DHC-7 was essentially a larger, four-engine version of the Twin Otter. The general layout remained similar, with a large T-tail intended to keep the elevator clear of the propwash during take-off, a high aspect ratio

 high-mounted wing, and most details of the cockpit and nose profile. Changes included the addition of cabin pressurization which required a switch to a fuselage with a circular cross-section and landing gear that folded forward into the inner engine nacelles.

The Twin Otter incorporated "flapperons" that drooped the ailerons as part of the flaps, but these were not included in the Dash 7 due to weight and complexity. Instead the ailerons were reduced in size to allow more flap area, and were augmented with two sets of roll-spoilers. The inboard roll spoilers operate at all speeds while the outboard roll spoilers only operate at speeds less than 130KIAS to allow for more roll control at slower speeds. Upon touchdown both the inboard and outboard roll spoilers extend in unison to aid in destroying lift created by the wing. Each wing also includes two ground spoilers which only extend on touchdown. Most of the rear wing was spanned by a complex double Fowler flap arrangement for high lift at low speed. During a typical STOL landing flaps would be selected to the 45° position. This flap setting allowed for steeper descents and slower approach speeds. Depending on weight the VREF speed with flaps at 45° would be between 70-85 knots. On touchdown, through switches in the main gear, the flaps would automatically retract to the 25° position and thus reduce lift once on the runway for better braking performance. The flaps would also retract to 25° when engine power was increased during a go-around

 was selected on landing, the props push air forward and slow the airplane effectively along with the anti-skid wheel brakes. More importantly, if an engine failed, the asymmetric thrust was much less than on a twin-engine layout, thereby increasing safety and allowing for a lower minimum control speed with an engine inoperative (VMC).

 with an enlarged cargo door. These were followed by the Series 110 which met British CAA requirements, including the -110 and -111, and finally the Series 150 which included additional fuel tankage and an improved interior in the -150 and -151. There were plans for a Series 200 with the new PT6A-50/7 engines which improved hot-and-high power, but these plans were shelved when Boeing ended production of the design.

The mixture of features on the Dash 7 met with limited commercial success. Most turboprop operators used them as feederliners into large airports, where the STOL performance wasn't considered important. In comparison to other feederliners, the Dash 7's four engines required twice the maintenance of a twin-engine model, thereby driving up operational costs. Finally, those airports that did require a high performance STOL operation were generally small and well served by the Twin Otters; had the airport needed a larger plane to serve its customer base, they would have built larger runways. One exception to this was operations at London City Airport
