National Airspace System: Experts' Views on Improving the U.S. Air Traffic Control Modernization Program
GAO-05-333SP: Published: Apr 13, 2005. Publicly Released: Apr 13, 2005.
In 1981, the Federal Aviation Administration (FAA) began a program to modernize the national airspace system and a primary component, the air traffic control (ATC) system. The ATC component of this program, which is designed to replace aging equipment and accommodate predicted growth in air traffic, has had difficulty for more than two decades in meeting cost, schedule, and performance targets. Th...
Air Traffic Control: FAA's Acquisition Management Has Improved, but Policies and Oversight Need Strengthening to Help Ensure Results
GAO-05-23: Published: Nov 12, 2004. Publicly Released: Dec 13, 2004.
The Federal Aviation Administration's (FAA) multibillion-dollar effort to modernize the nation's air traffic control (ATC) system has resulted in cost, schedule, and performance shortfalls for over two decades and has been on GAO's list of high-risk federal programs since 1995. According to FAA, performance shortfalls were due, in part, to restrictions imposed by federal acquisition and personnel...
Air Traffic Control: FAA Needs to Ensure Better Coordination When Approving Air Traffic Control Systems
GAO-05-11: Published: Nov 17, 2004. Publicly Released: Nov 17, 2004.
The Federal Aviation Administration's (FAA) process for ensuring that air traffic control (ATC) systems will operate safely in the national airspace system is an integral part of the agency's multibillion-dollar ATC modernization and safety effort. GAO was asked to review (1) FAA's process for approving ATC systems for safe use in the national airspace system; (2) challenges FAA has faced approvin...
Air Traffic Control: System Management Capabilities Improved, but More Can Be Done to Institutionalize Improvements
GAO-04-901: Published: Aug 20, 2004. Publicly Released: Sep 20, 2004.
Since 1981, the Federal Aviation Administration (FAA) has been working to modernize its aging air traffic control (ATC) system. Individual projects have suffered cost increases, schedule delays, and performance shortfalls of large proportions, leading GAO to designate the program a high-risk information technology initiative in 1995. Because the program remains a high risk initiative, GAO was requ...
Information Technology: FAA Has Many Investment Management Capabilities in Place, but More Oversight of Operational Systems Is Needed
GAO-04-822: Published: Aug 20, 2004. Publicly Released: Sep 20, 2004.
The Federal Aviation Administration's (FAA) mission is to promote the safe, orderly, and expeditious flow of air traffic in the United States airspace system, commonly referred to as the National Airspace System (NAS). To maintain its ability to effectively carry out this mission FAA embarked, in 1981,on a multi-billion dollar effort to modernize its aging air traffic control (ATC) system, the pri...
Federal Aviation Administration: Plan Still Needed to Meet Challenges to Effectively Managing Air Traffic Controller Workforce
GAO-04-887T: Published: Jun 15, 2004. Publicly Released: Jun 15, 2004.
In the summer of 2000, the air traffic control system lacked the capacity to handle demand efficiently, and flight delays produced near-gridlock conditions at several U.S. airports. A combination of factors, including the crises instigated by the events of 9/11, temporarily reduced air traffic, but air traffic is now back to near pre-9/11 levels. The ability of the air traffic control system to ha...
Federal Aviation Administration: Challenges for Transforming Into a High-Performing Organization
GAO-04-770T: Published: May 18, 2004. Publicly Released: May 18, 2004.
Over the last two decades, FAA has experienced difficulties meeting the demands of the aviation industry while also attempting to operate efficiently and effectively. Now, as air traffic returns to pre- 9/11 levels, concerns have again arisen as to how prepared FAA may be to meet increasing demands for capacity, safety, and efficiency. FAA's air traffic control (ATC) modernization efforts are desi...
Air Traffic Control: FAA's Modernization Efforts--Past, Present, and Future
GAO-04-227T: Published: Oct 30, 2003. Publicly Released: Oct 30, 2003.
The Federal Aviation Administration's (FAA) air traffic control modernization (ATC) efforts are designed to enhance the safety, capacity, and efficiency of the national airspace system through the acquisition of a vast network of radar, navigation, communications, and information processing systems, as well as new air traffic control facilities. Since 1981, when these efforts began, FAA's ATC mode...
Aviation Safety: Information on FAA's Data on Operational Errors At Air Traffic Control Towers
GAO-03-1175R: Published: Sep 23, 2003. Publicly Released: Sep 24, 2003.
A fundamental principle of aviation safety is the need to maintain adequate separation between aircraft and to ensure that aircraft maintain a safe distance from terrain, obstructions, and airspace that is not designated for routine air travel. Air traffic controllers employ separation rules and procedures that define safe separation in the air and on the ground.1 An operational error occurs when...
National Airspace System: Current Efforts and Proposed Changes to Improve Performance of FAA's Air Traffic Control System
GAO-03-542: Published: May 30, 2003. Publicly Released: May 30, 2003.
To accelerate the modernization and improve the performance of the air traffic control system, the Wendell H. Ford Aviation Investment and Reform Act for the 21st Century (AIR-21) created the Air Traffic Services Subcommittee (subcommittee) to over see the air traffic control system and help the Federal Aviation Administration (FAA) address long-standing weaknesses in its modernization program. Th...
