Air Traffic Control: Complete and Enforced Architecture Needed for FAA Systems Modernization.

摘要

Effectively and efficiently designing and constructing a building requires a complete blueprint that defines the building's features, functions, and systems as well as how these components interrelate and how they are to be crafted, including applicable building codes, rules, and standards. Effective and efficient modernization of an organization's computer systems requires no less. Accordingly, the Congress has emphasized in law the importance of agencies' Chief Information Officers (CIO) developing and implementing system blueprints, commonly called architectures, to guide current and future systems development and evolution. Because of the size, complexity, and importance of FAA's air traffic control (ATC) modernization, we 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.
