Aviation is playing an increasingly important role in developing the resource potential of northern Canada. It is the most common means of supplying the oil rigs on Melville Island, the mining camps in the Mackenzie Mountains, and the meteorological stations on the pack ice. New technology has increased both capability and capacity. Pipe and drilling equipment can now be flown non-stop from southern Canada to airfields on the Queen Elizabeth Islands; helicopters able to carry two tons then distribute the equipment to well sites. Very rapid and precise land surveying can be conducted using the Bell Jet Ranger helicopter. Recently, a 16 640 km2 region of northern Alberta was surveyed in less than five days.
