Trade Otter Tail
de Haviland Canada DHC-3 Otter is a single engine, high-wing, propeller-driven, short take-off and landing (STOL) aircraft developed by De Haviland Canada. It has been conceived to be able to perform the same roles as earlier and highly successful Beaver, including as a Bush captain, but generally a larger aircraft. rugged single-engine, high-wing, propeller-driven DHC-3 Otter was conceived in January 1951 by De Haviland Canada as the largest, more powerful version of the highly successful DHC2 Beaver STOL transport ation facilities. Dubbed the "Beaver King" during the design, it will be a real "one ton truck" for the role of the beaver "half a ton". Otter received a Canadian certificate in November 1952 and entered production shortly thereafter. Using the same general configuration as beaver, the new design ensures a much heavier fuselage, a larger wing, and a cruciform tail. Seats in the main cabin have expanded from six to 10 or 11. The power is powered by 450 kW (600 hp) Pratt and Whitney R-1340 radio-guided. The version used in Otter was geared to lower fan revolutions and therefore lower air speed. The electrical system was 28 voltd D.C.
