Abstract:Because of the size, complexity, and importance of FAA's air traffic control
(ATC) modernization, the General Accounting Office (GAO) reviewed it to
determine (1) whether FAA has a target architecture(s), and associated
subarchitectures, to guide the development and evolution of its ATC
systems; and (2) what, if any, architectural incompatibilities exist
among ATC systems, and the effect of these incompatibilities. The
GAO found the FAA lacks a complete systems architecture, or overall
blueprint, to guide and constrain the development and maintenance of
the many interrelated systems comprising its ATC infrastructure. While
the FAA is developing one of the two principal components of a complete
systems architecture, namely the "logical" description of FAA's current
and future concept of ATC operations, FAA is not developing, nor does
it have plans to develop, the second essential component-the ATC-wide
"technical" description which defines all required information technology
and telecommunications standards and critical ATC systems' technical
characteristics.
