Abstract:Comparing the currently projected cost and deployment schedule for
STARS with the original cost and schedule is difficult because the program
presently bears little resemblance to the program envisioned in 1996. At
that time, FAA contracted with the Raytheon Corporation for a system
using commercially available technology that could be deployed
throughout the National Airspace System with very little software
development. The plan was to install STARS in 172 facilities at a cost of
$940 million with implementation to begin in 1998 and be completed in
2005. However, in 1997, when FAA controllers first tested an early version
of this commercially available system, they raised some concerns about the
way aircraft position and other data were displayed and updated on the controllers’ radar screens. For example, the controllers said the system did
not provide enough detail about an aircraft’s position and movement,
which could hamper their ability to monitor traffic movement. To address
these concerns, as well as others identified by the technicians who
maintain the system, FAA decided to develop a more customized system
that is software dependent and to deploy an incremental approach, thereby
enabling controllers and technicians to adjust to some changes before
introducing others. Because this incremental approach requires more
custom software than initially planned, it also costs more and is taking
longer to implement than the original STARS project.
