Book excerpt: Excerpt from Helicopter Logging: A Model for Locating Landings Binkley [1972] Edholm (1973, and Stevens (1972, 1973) have reported the general production and cost aspects of helicopter logging. The studies show that heli copter logging is expensive and warrants efforts to design an operating system in the most economical manner possible. Gibson (1974) developed a cost model that, given parameters of a system, specified optimum refueling of the aircraft. This paper presents another tool for designing and managing a helicopter logging sale by presenting a computer model that specifies the number and location of landings to which the timber should be yarded. Considerations include areas not suitable for landings, and flight path restrictions such as ridges or other obstacles. Alternative landing sites are evaluated by total cost of yarding, landing construction, and hauling. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
