Aviation Runway and Ramp Safety: Sustained Efforts to Address Leadership, Technology, and Other Challenges Needed to Reduce Accidents and Incidents
GAO-08-29: Published: Nov 20, 2007. Publicly Released: Dec 5, 2007.
While aviation accidents in the United States are relatively infrequent, recent incidents have heightened concerns about safety on airport runways and ramps. As the nation's aviation system becomes more crowded every day, increased congestion at airports may exacerbate ground safety concerns. To safely handle the anticipated larger volumes of air traffic, the Federal Aviation Administration (FAA)...
Federal Aviation Administration: Key Issues in Ensuring the Efficient Development and Safe Operation of the Next Generation Air Transportation System
GAO-07-636T: Published: Mar 22, 2007. Publicly Released: Mar 22, 2007.
The Federal Aviation Administration (FAA) operates one of the safest air transportation systems in the world. It is, however, a system under strain. The skies are becoming more crowded every day, with an estimated 1 billion passengers per year expected by 2015. The current aviation system cannot be expanded to meet this growth. The reauthorization of FAA is an opportunity to examine how the agency...
Federal Aviation Administration: Challenges Facing the Agency in Fiscal Year 2008 and Beyond
GAO-07-490T: Published: Feb 14, 2007. Publicly Released: Feb 14, 2007.
FAA operates one of the safest air transportation systems in the world. It is, however, a system under strain. The skies over America are becoming more crowded every day. FAA faces the daunting task of safely integrating a growing influx of passengers and aircraft into the system and simultaneously leading the transition to the Next Generation Air Transportation System (NextGen)--a complicated eff...
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...
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...
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...
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...
Air Traffic Control: FAA Enhanced the Controller-in-Charge Program, but More Comprehensive Evaluation is Needed
GAO-02-55: Published: Oct 31, 2001. Publicly Released: Nov 13, 2001.
Each day, nearly two million passengers on 25,000 flights depend on the Federal Aviation Administration's (FAA) Air Traffic Control (ATC) system to safely reach their destinations. Because the ATC system requires thousands of controllers, each of whom typically manages just a section of airspace or one aspect of an aircraft's takeoff or landing, FAA depends on supervisors to monitor air traffic op...
Aviation Security: Terrorist Acts Demonstrate Urgent Need to Improve Security at the Nation's Airports
GAO-01-1162T: Published: Sep 20, 2001. Publicly Released: Sep 20, 2001.
A safe and secure civil aviation system is a critical component of the nation's overall security, physical infrastructure, and economic foundation. Billions of dollars and myriad programs and policies have been devoted to achieving such a system. Although it is not fully known at this time what actually occurred or what all the weaknesses in the nation's aviation security apparatus are that contri...
