Abstract:Certain air traffic control(ATC) centers experienced a series of major outages,
some of which were caused by the Display Channel Complex or DCC-a mainframe
computer system that processes radar and other data into displayable images on
controllers' screens. DCC outages caused by old, out-of-production equipment
have disrupted airtraffic. The Federal Aviation Administration (FAA) decided
to acquire an interim replacement, calling it the DCC Rehost (DCCR), and deploy
it to all affected centers by early 1998. In light of the importance of DCC-
and its to be short-lived replacement(DCCR)-to FAA's ATC mission, as well as
FAA's limited success in delivering promised ATC system capabilities on time
and within budget, the General Accounting Office (GAO) reviewed the DCCR
project and made recommendations for risk management. This document is the
GAO report to the Secretary of Transportation.
