Role of NAPCA in Controlling Aircraft Pollutant Emissions

The National Air Pollution Control Administration (NAPCA) initiated a program in 1967 on the characterization and control of aircraft emissions. The program, which is being carried out through contract research and cooperative government-industry studies, covers the measurement of emissions, development of testing instrumentation and procedures, and basic research in emission control technology.

Some of the general results of this program are presented. A brief description of NAPCAs plans for future research is included. The paper concludes with a discussion of possible emission control techniques and regulatory considerations which will affect future standard setting.
