The Relationship of General Aviation-Associated Products and Services to the National Economy, 1977

This study addresses two questions: What were the contributions made by the general aviation (GA) industry to the Gross National Product (GNP) and Gross National Income (GNI) in 1977? What were the aggregate resource savings and consumer benefits (to the economy) attributable to the use of general aviation in 1977? To answer the first question requires measuring the economic activity in the general aviation industry in the year 1977. Answering the second question requires estimating economic losses that would have occurred in the absence of the general aviation industry in 1977. Because these questions are different, two separate sets of methodologies were developed to answer them. (Author)
