Title: HIGH-SPEED CRUISE ENVIRONMENTAL CONCERNS
Accession Number: 00470902
Record Type: Component
Availability: Find a library where document is available Abstract: A major unresolved environmental issue is sonic boom overland. Present Federal Aviation Regulations prohibit supersonic flight by civil aircraft over the United States. However, the prohibition is not outright, in that the regulations also include provisions for future demonstration that a specific aircraft might have environmentally acceptable sonic boom characteristics. Concern about the effects of supersonic flight on the atmosphere has shifted somewhat in recent years. Earlier apprehension about the impact on air quality has lessened as a result of experience with military and Concorde supersonic operations and more precise understanding of how man-made pollutants affect atmospheric chemistry. On the other hand, concern has increased about the consequences of high-altitude flight on the ozone layer. Establishment of criteria for acceptable emission levels by future supersonic and hypersonic aircraft will require better understanding of the chemistry and dynamics of the earth's total ozone column. If development of supersonic and hypersonic aircraft is to proceed, it will be necessary to set emissions criteria at an early date -- a task that will call for shared responsibility and effort by the air transport industry, the public, the scientific community, and the federal government.
