de Havilland DHC-3 Otter

DESIGN PHILOSOPHY:    STOL utility aircraft with a larger cabin and greater payload capability than the Beaver. As with the Beaver, the Otter is very versatile, operating on wheels, floats, amphibious gear, skis and wheel/skis. The main new concept introduced on the Otter was the full-span double-slotted flap (with the outboard trailing flaps also serving as ailerons).
