Report No. IMTEC-92-1
Subject
Summary:

Software problems at air route traffic control centers continue to disrupt the air traffic control system. Since 1987, when the Federal Aviation Administration (FAA) installed new hardware to help control air traffic, almost 4,000 system software problems have been reported; as of June 30, 1991, more than 1,600 of these problems remained unresolved. FAA's efforts to resolve software problems have been neither timely nor effective. FAA attributes its backlog of software problems and continued reliance on temporary fixes to a lack of necessary resources. It has not, however, developed a plan to identify the resources needed to maintain the en route system until modernization is completed, and it lacks key tools to estimate the resources required for such maintenance.
