Challenges with Implementing Near-Term NextGen Capabilities at Congested Airports Could Delay Benefits [open pdf - 437KB]
"The Federal Aviation Administration (FAA) estimates that there are about 7,000 aircraft in the air over the United States at any given time. To better manage this traffic and meet future air travel demands, FAA is developing the Next Generation Air Transportation System (NextGen), a satellite-based air traffic control system intended to replace the current ground-based system. NextGen involves a significant overhaul of the National Airspace System (NAS) that will require multibillion-dollar investments from both Government and airspace users. […] The Chairmen and Ranking Members of the House Committee on Transportation and Infrastructure and its Subcommittee on Aviation asked us to review FAA's actions to address the task force's recommendations. Accordingly, our audit objectives were to assess the extent to which FAA is (1) responding to the recommendations, including adjusting its budgets and establishing mechanisms for continued industry collaboration, and (2) addressing barriers that may hinder its ability to successfully implement the recommendations."
