The versatile backcountry Beaver was introduced in 1947 by the de Havilland Aircraft Company, in Canada, and gained a reputation as a workhorse. Since the 1980s, Viking Air has been converting the de Havilland Beaver pistons to turbine planes, with longer cabins and increased payload capabilities. Bigger windows improve visibility from the cockpit, and a larger tail adds rudder authority. The aircraft is available in several configurations for operations on water, snow, tundra, or tarmac. Each airplane is custom-built with lots of options to choose from.
