Eight aviation groups have joined together in welcoming an updated study detailing the robust contributions of general aviation to the U.S. economy. Conducted by PwC US Tax LLP, the updated study determined that general aviation (GA) supports a total of 1,330,200 jobs and a total of $339.2 billion in total economic output in the U.S. Both figures are sizable increases over an initial PricewaterhouseCoopers study conducted five years ago.
