AIR TRAFFIC CONTROL: UNCERTAINTIES AND CHALLENGES FACE FAA'S ADVANCED AUTOMATED SYSTEM. TESTIMONY

This is the testimony of Kenneth M. Mead, Director, Transportation Issues, Resources, Community, and Economic Development Division, General Accounting Office, before the Subcommittee on Transportation and Related Agencies, Committee on Appropriations, House of Representatives, on the Advanced Automation System (AAS)--the largest project in the Federal Aviation Administration's (FAA's) $33 billion program to modernize the nation's air traffic control system. Structured in five segments, AAS is being developed and implemented over a 20-year period using a "building block" approach. Segments one and two of AAS replace equipment that helps controllers separate aircraft en route between airports. The third segment replaces equipment relied upon by controllers to separate aircraft within 20-30 miles of airports. The fourth segment controls aircraft on the ground and in the immediate vicinity of an airport. The fifth and final segment of AAS combines equipment from segments one, two, and three into a single consolidated facility and provides new software that will permit controllers to grant aircraft more fuel-efficient routes. Only the first segment has been completed. The testimony describes the latest schedule delays and cost growth for AAS, the causes of these problems, the actions taken to address problems with the second segment of AAS and the challenges that still lie ahead for that segment, and the need to restructure AAS.
