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: Role of FAA's Modernization Program in Reducing Delays and Congestion
GAO-01-725T: Published: May 10, 2001. Publicly Released: May 10, 2001.
This testimony discusses the Federal Aviation Administration's (FAA) efforts to modernize the nation's air traffic control (ATC) system and its relationship to other initiatives to address the escalating crises of insufficient capacity facing the aviation industry. Specifically, GAO reviews the (1) extent of the delay and congestion problems and the contribution of the ATC system to them, (2) prog...
Air Traffic Control: Information Concerning Equipment Outages at Two Kansas City Area Facilities
RCED-98-256R: Published: Aug 14, 1998. Publicly Released: Aug 19, 1998.
Pursuant to a congressional request, GAO reviewed the reliability of the equipment at two Kansas City area air traffic control (ATC) facilities and the Federal Aviation Administration's (FAA) ability to safely direct air traffic in this area, focusing on: (1) the impact the equipment's outages had on the safety of the ATC system and on airline operations; (2) identifying procedures to help ensure...
National Airspace System: Issues in Allocating Costs for Air Traffic Services to DOD and Other Users
RCED-97-106: Published: Apr 25, 1997. Publicly Released: Apr 25, 1997.
Pursuant to a legislative requirement, GAO reviewed the issues that must be resolved in allocating costs for air traffic services to the Department of Defense (DOD) and other users, focusing on: (1) funding options for DOD's share of costs if DOD is found to owe a payment to the Federal Aviation Administration (FAA); and (2) the potential for better management of special-use airspace.GAO noted tha...
Air Traffic Control: Issues Presented by Proposal to Create a Government Corporation
T-RCED-95-114: Published: Feb 23, 1995. Publicly Released: Feb 23, 1995.
GAO discussed proposals to reform the air traffic control (ATC) system, focusing on the administration's proposal to create a privatized ATC system. GAO noted that: (1) under the proposal, the Federal Aviation Administration (FAA) would continue to provide safety oversight, but a self-sufficient government corporation would operate the ATC system; (2) the corporation could be viable if the proposa...
Airspace System: Emerging Technologies May Offer Alternatives to the Instrument Landing System
RCED-93-33: Published: Nov 13, 1992. Publicly Released: Nov 13, 1992.
Pursuant to a congressional request, GAO reviewed aircraft landing systems, focusing on: (1) capabilities and costs; and (2) potential consequences of the FAA approach to developing these systems.GAO found that: (1) the current instrument landing system (ILS) cannot be adapted to use enhanced systems features, is limited in coverage area, cannot be used in all locations, and is sensitive to signal...
Aviation Safety: Additional Actions Needed for Three Safety Programs
T-RCED-92-90: Published: Aug 4, 1992. Publicly Released: Aug 4, 1992.
GAO discussed the Federal Aviation Administration's (FAA) progress in three programs to improve aviation safety. GAO noted that: (1) FAA has not established a planned database to monitor older aircraft safety compliance, but intends to issue a report to Congress in September 1992; (2) the report will not help FAA track modifications and repairs performed on older aircraft or capture information on...
Air Traffic Control: Efforts to Modernize Oceanic System Delayed
IMTEC-91-2: Published: Jan 16, 1991. Publicly Released: Jan 16, 1991.
GAO reviewed the Federal Aviation Administration's (FAA) efforts to provide automation support to improve oceanic air traffic control.GAO found that: (1) air traffic control services in oceanic areas not under radar surveillance have not changed significantly since 1950; (2) oceanic air traffic controllers lacked a modern automated system and manually updated flight progress based on periodic radi...
Air Traffic Control: Status of FAA's Effort to Modernize the System
RCED-90-146FS: Published: Apr 17, 1990. Publicly Released: Apr 17, 1990.
Pursuant to a congressional request, GAO reviewed the status of the Federal Aviation Administration's (FAA) National Airspace System Plan (NAS), focusing on the: (1) overall status of the program; and (2) program's 12 major systems' projected cost and schedule as of January 1990.GAO found that: (1) FAA had completed 28 projects, or about 32 percent of all NAS projects, but the completed projects r...
