Aircraft noise is the single major impediment to airport expansion and to the development of new airports in the United States. The issue of aircraft noise must continue to be addressed on a national and local basis to avoid the imposition of onerous operational restrictions, such as curfews, and to eventually progress to the point where significant expansion of the system can be seriously considered. The existing situation and future outlook are considered. Total compliance with the federal fleet noise rule will improve the situation at most major airports by eliminating 4-engined narrow-bodied aircraft with low bypass ratio engines (B-707 and DC-8) and by improving, to some extent, the noise performance of 2 and 3-engined aircraft of the same type (B-727, B-737 and DC-9). These 2 and 3-engined aircraft that remain, however, will dominate the noise picture at the nation's impacted airports for many years. From a source noise point of view, the answer is clear; replace those aircraft powered by low bypass JT-8D engines. If these aircraft were replaced by new technological wide-bodied aircraft or reengined to meet FAR-36 Stage 3 standards, the aircraft-noise problem would virtually disappear. Unfortunately, the competition fostered by airline deregulation and the present state of airline economics lead to the conclusion that the aircraft powered by the JT-8D, which currently represent almost three quarters of the United States' fleet, will remain in service much longer than might have been anticipated several years ago, based upon normal depreciation of this type of equipment and the operational cost-differential in favor of new technology replacement. Unless conditions change radically, the continued operations of these aircraft promises that there will not be a significant perceptible reduction in the impact of aircraft noise at the major U.S. airports over the next decade and beyond and that the noise constraint on system capacity will become more rather than less severe in that time frame.
