Technological Innovation
Aviation system disruptions in the aftermath of the PATCO strike led many in FAA to come to the realization that the agency needed a systematic, long-term plan for modernization. In January 1982, FAA publicly released the first annual National Airspace System (NAS) Plan, a comprehensive 20-year blueprint for a state-of-the-art traffic control and air navigation system to accommodate projected growth in air travel.
As the modernization program evolved, problems in developing ambitious automation systems prompted a change in strategy. FAA shifted its emphasis from the advanced automation system toward enhancing the ATC system through more manageable, step-by-step improvements through the new Free Flight program. At the same time, the agency worked to speed the application of the Global Positioning System satellite technology to civil aeronautics.
In February 1991, FAA replaced the NAS Plan with the more comprehensive Capital Investment Plan. The new plan incorporated the NAS plan projects and included higher levels of automation as well as new radar, communications, and weather forecasting systems.
FAA also addressed a wide variety of technical issues as the rapid evolution of aeronautics continued. The Aviation Safety Research Act of 1988, for example, mandated greater emphasis on long-range research planning and on study of such issues as aging aircraft structures and human factors affecting safety. FAA engineers and scientists also investigated areas such as human performance in aeronautical tasks, improvement of runways, and the effects of corrosion on aircraft structures.
