Critical Issues in Aviation and the Environment

TRB Transportation Research E-Circular E-C148: Critical Issues in Aviation and the Environment explores the environmental media affected by aviation activities and processes that link aviation and the environment. The circular consists of nine individually authored sections representing the authors' expert opinions on these issues.

E-C148 updates and expands upon previous circulars while maintaining their cross-disciplinary approach to reviewing subjects of interest to the civil aviation community in the United States. The circular focus is on the state of science, rather than on policy, and on identifying priority research with the potential to yield benefits during the next several years to several decades.
