The Dash8 was an economic replacement to the Dash7 not a technical improvement. The Dash7s legendary stol performance was deemed unneccessary as was the requirement for its ultra short balanced field take off requirements. When the Dash7 was conceived it was thought that it would be more viable to operate ultra stol aircraft from existing 2nd and 3rd world strips than to improve runway lengths. As the demand for safety requirements the balanced field capabilities of its 4 engines were unnecessary and economically unviable. Thus the need for the more economically efficient if less STOL capable DASH8 which more closely satisfied modern requirements.
