Pursuant to a congressional request, GAO examined the computer systems the Federal Aviation Administration (FAA) uses to safely control air traffic, focusing on: (1) the extent to which computer software problems affect FAA control of air traffic en route between airports; and (2) whether FAA actions to minimize and resolve those problems are timely and effective. GAO found that: (1) since 1987, when FAA implemented new hardware, almost 4,000 system software problems have been reported and, as of June 1991, 1,600 problems remained unresolved; (2) FAA considers 74 percent of the unresolved problems to have the potential to adversely affect the air traffic control system; (3) software problems have remained uncorrected for an average of 18 months; (4) FAA effectiveness in reducing problems is limited because it uses temporary fixes for software problems instead of permanently revising software; (5) FAA attributes the backlog of software problems and continued reliance on temporary fixes to a lack of necessary resources; and (6) FAA has not developed a plan identifying the resources needed to maintain the en-route system until modernization is completed and lacks the key tools to estimate the resources required for such maintenance.
