National Airspace System: Transformation will Require Cultural Change, Balanced Funding Priorities, and Use of All Available Management Tools
GAO-06-154: Published: Oct 14, 2005. Publicly Released: Nov 14, 2005.
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 m...
Information Security: Progress Made, but Federal Aviation Administration Needs to Improve Controls over Air Traffic Control Systems
GAO-05-712: Published: Aug 26, 2005. Publicly Released: Sep 26, 2005.
The Federal Aviation Administration (FAA) performs critical functions that contribute to ensuring safe, orderly, and efficient air travel in the national airspace system. To that end, it operates and relies extensively on an array of interconnected automated information systems and networks that comprise the nation's air traffic control systems. These systems provide information to air traffic con...
Air Traffic Control: Characteristics and Performance of Selected International Air Navigation Service Providers and Lessons Learned from Their Commercialization
GAO-05-769: Published: Jul 29, 2005. Publicly Released: Jul 29, 2005.
In the past, governments worldwide owned, operated, and regulated air navigation services, viewing air traffic control as a governmental function. But as nations faced increasing financial strains, many governments decided to shift the responsibility to an independent air navigation service provider (ANSP) that operates as a business. As of March 2005, 38 nations worldwide had commercialized their...
Air Traffic Operations: The Federal Aviation Administration Needs to Address Major Air Traffic Operating Cost Control Changes
GAO-05-724: Published: Jun 23, 2005. Publicly Released: Jul 26, 2005.
Dating back to 1997, numerous reports have highlighted the need for the Federal Aviation Administration (FAA) to better control the growth in its Air Traffic Services operating costs, which account for about $6.5 billion or over 80 percent of FAA's total annual operating costs. In February 2004, FAA established the Air Traffic Organization (ATO) to take over its entire Air Traffic operations and e...
National Airspace System: FAA Has Made Progress but Continues to Face Challenges in Acquiring Major Air Traffic Control Systems
GAO-05-331: Published: Jun 10, 2005. Publicly Released: Jul 11, 2005.
The Federal Aviation Administration's (FAA) multibillion-dollar effort to modernize the nation's air traffic control (ATC) system has suffered from cost, schedule, and/or performance shortfalls in its system acquisitions for more than two decades and has been on our list of high risk programs since 1995. FAA's performance-based Air Traffic Organization (ATO) was created in February 2004, in part,...
Federal Aviation Administration: Stronger Architecture Program Needed to Guide Systems Modernization Efforts
GAO-05-266: Published: Apr 29, 2005. Publicly Released: May 31, 2005.
The Federal Aviation Administration's (FAA) mission is to promote the safe, orderly, and expeditious flow of air traffic in the U.S. airspace system. To this end, FAA is modernizing its air traffic control systems, a multibillion dollar effort that GAO has designated as a high-risk program. GAO's research into the practices of successful public- and private-sector organizations has shown that deve...
National Airspace System: Initiatives to Reduce Flight Delays and Enhance Capacity are Ongoing but Challenges Remain
GAO-05-755T: Published: May 26, 2005. Publicly Released: May 26, 2005.
Since the unprecedented flight delays in 2000, a year in which one in four flights were delayed, our aviation system has been adversely affected by many unanticipated events--such as the September 11th terrorist attacks, and Severe Acute Respiratory Syndrome (SARS)--that significantly reduced the demand for air travel. However, demand for air travel is rebounding. For example, the number of passen...
Airport and Airway Trust Fund: Preliminary Observations on Past, Present, and Future
GAO-05-657T: Published: May 4, 2005. Publicly Released: May 4, 2005.
The Airport and Airway Trust Fund (Trust Fund) was established in 1970 to help fund the development of a nationwide airport and airway system and to fund investments in air traffic control facilities. It provides all of the funding for FAA's accounts such as the Airport Improvement Program (AIP), which provides grants for construction and safety projects at airports, the Facilities and Equipment (...
Air Traffic Control: Preliminary Observations on Commercialized Air Navigation Service Providers
