B/CA ANALYSIS: DE HAVILLAND'S DASH 7 STOLINER

Characteristics of the popular 50-passenger commuter liner are described. The DHC-7 achieves much of its STOL performance from powerful double-slotted fowler flaps that span 80% of its 93-foot wing. Fully extended, they reduce DHC-7's stalling speed by 34 knots at its gross weight of 44,000 pounds-from 100 knots with the flaps retracted to 66 knots at their 45-degree position. Other performance aspects of this aircraft are noted. A comparison profile chart is presented which considers 40 parameters. Graphs are provided which illustrate the range-payload and range-time capabilities of the DHC-7. Although the DHC-7 uses an hydraulic, double-hinged rudder control system, with no mechanical linkages between the rudder pedals and the control surface, the aircraft is flyable with all hydraulics inoperative.
