The U.S. Government Accountability Office (GAO) is an independent agency that works for Congress. The GAO watches over Congress, and investigates how the federal government spends taxpayers dollars. The Comptroller General of the United States is the leader of the GAO, and is appointed to a 15-year term by the U.S. President. The GAO wants to support Congress, while at the same time doing right by the citizens of the United States. They audit, investigate, perform analyses, issue legal decisions and report anything that the government is doing. This is one of their reports.

GAO-05-331 National Airspace System: FAA Has Made Progress but Continues to Face Challenges in Acquiring Major Air Traffic Control Systems

" Through the NextGen initiative, FAA plans to transform the current ground-based radar air-traffic control system to a system based on satellite navigation, automated position reporting, and digital communications. The NextGen transition will be a complex, multi-year, incremental process. Decisions affecting how long the transition will take and the number of existing systems that will remain in operation during the transition have implications for FAA's existing systems, workforce, facilities, and budget. GAO was asked to continue monitoring the progress and challenges associated with the NextGen transition and implementation. In this report, GAO examined (1) FAA's progress in addressing key challenges affecting its ability to execute the NextGen transition; (2) the performance and condition of current air traffic control system and facilities; (3) FAA's efforts to address maintenance requirements of its current systems and facilities; and (4) the extent to which FAA has planned for the financial resources for sustaining existing systems and facilities and the NextGen transition. In doing so, GAO analyzed FAA system performance data and documents and interviewed FAA officials and aviation stakeholders. "

Discusses six issues that are important in reauthorizing FAA programs: (1) Ensuring the safe and efficient transformation to the Next Generation Air Transportation System (NextGen); (2) Strengthening oversight of aviation safety: Incomplete and inaccurate safety data jeopardize FAA's implementation of a new safety management approach; (3) Reducing congestion and providing access to the national airspace system; (4) Addressing aviation's impact on the environment, including noise, emissions, and other pollutants; (5) Ensuring a sufficient, trained workforce; and (6) Ensuring timely reauthorization of FAA programs.
