The Next Generation Air Transportation System, or NextGen, represents the modernization of the United States air transportation system. It is a shift from legacy computer and radar based technologies to an integrated set of technologies, connected into a real time data sharing “system,” shared by air traffic control, pilots and airports. This upgrade to our National Airspace System (NAS) involves potentially significant changes and financial considerations for many air operators. The upgrade and integration of one of these technologies, the Automatic Dependent Surveillance – Broadcast (ADS-B) transmitter, is among the mandatory upgrades being required by the Federal Aviation Administration within a few years. This paper explores the cost and benefits of this specific NextGen technology for general aviation owner/operators, takes a specific look at the implications for flight training schools, and details the many ways that general aviation pilots can access and use the new information in the cockpit.
