Page 28 - The purposes of this title are (1) to protect and enhance the quality of the Nation's air resources so as to promote the public health and welfare and the productive capacity of its population...
Page 7 - County versus a present contribution of less than 1 percent. 3. Based on emission densities, the average level of atmospheric pollution at selected air terminals and their immediate vicinity is calculated to be of comparable magnitude to that in the communities in which the terminals are located. 4. Under conditions of heavy airport traffic, exposures to high concentrations of exhaust contaminants are likely to occur in aircraft loading areas and in the cabins of aircraft lined up awaiting takeoff....
Page 7 - A. IMPACT OF AIRCRAFT EMISSIONS 1. Exhaust emissions from piston and jet aircraft include the same pollutants emitted by highway vehicles, as well as certain other pollution sources, and, consequently, participate in the same air pollution problems. 2. The present contribution of aircraft emissions to the total atmospheric pollution burden of the community is considered small. The magnitude of this relative contribution is expected to grow...
Page 13 - Senator, that as we develop additional r' technology the day may come in the not too distant future when we •. may want to preempt this field.
Page 8 - Further research is needed to define more precisely the present and probable future nature and magnitude of all other air pollution problems associated with aircraft activity in the United States and to identify needs for control measures. Emphasis must be placed particularly on assessment of air pollutant levels in the air terminal environment and their effects on health and safety and on evaluation of possible long-term effects of upper atmospheric pollution resulting from aircraft flight activity.
Page 7 - The control of oxides of nitrogen from aircraft is not deemed to be feasible on the basis of current information. 7. Control of aircraft emissions by altering fuel composition is not indicated in the light of the control potential of other approaches considered. C. CONCLUSIONS AND RECOMMENDATION 1. Reduction of particulate emissions from jet aircraft is both desirable and feasible. Engine manufacturers and airlines have indicated that improvements in turbine engine combustor design can be built into...
Page 8 - ... as measures to achieve such control become available through research and development, it is the Department's expectation that engine manufacturers, airline operators, and other segments of the aviation community will take the initiative in the development and application of such control measures. If the private sector fails to provide adequate controls, the Department will not hesitate to recommend to the Congress that Federal regulatory action be authorized.
Page 7 - ... control technology. 2. Turbine-engine combustor technology for effectively eliminating the visible plume seems assured for application in the very near future, both to new engines and to replacement combustor components for existing engines. When applied to existing aircraft, according to regular replacement schedules of such engines and combustor units, the cost is not expected to be a significant factor. Safety, in terms of engine relight characteristics, is not expected to be degraded thereby....
Page 21 - ... Federal Aviation Administration. We are, in short, concerned very broadly with the impact of aircraft emissions on the Nation's air quality and on public health and welfare. As we succeed in defining specific aspects of the problem and identifying practical means of dealing with them, we intend to seek prompt application of that knowledge. To the extent that enactment of laws and regulations is necessary at any point in this effort, we will recommend that approach. But wherever there are opportunities...
Page 7 - Exhaust emissions from piston and jet aircraft include the same pollutants emitted by highway vehicles, as well as certain other pollution sources, and, consequently, participate in the same air pollution problems. 2. The present contribution of aircraft emissions to the total atmospheric pollution burden of the community is considered small. The magnitude of this relative contribution is expected to grow, largely as a result of effective emission control legislation applicable to highway vehicles....
