The National Airspace System (NAS) is a complex network of airports, aircraft, air traffic control (ATC) facilities, employees, and pilots. The aviation industry, which depends on the NAS, contributes about 9 percent to the gross domestic product. The Federal Aviation Administration (FAA), funded through a tax-financed trust fund and General Fund appropriations, is pursuing a multibillion-dollar modernization program. Persistent cost, schedule, and/or performance shortfalls have kept this program on GAO's list of high-risk programs since 1995. GAO was asked to review the status of NAS modernization. This report addresses NAS status by identifying the challenges that FAA faces in managing (1) infrastructure, (2) human capital, and (3) financial resources. |
