Abstract : The impact of high altitude aviation on stratospheric ozone is now believed to be a decrease in total columnar ozone for flights above 15 km (about 49,000 feet). The model calculations also show that the current subsonic fleet (and the fleet foreseeable to 1990) will result in a net ozone increase of about 1 percent, considering normal flight altitudes. Whatever the net change in total column ozone, increases or depletions will occur at different altitudes. These are expected to have subtle influences on atmospheric circulation, the effects of which are only beginning to be understood. As a formal program, the High Altitude Pollution Program will be terminated in 1982 with the issuance of a final report. The FAA will continue to maintain and update, as appropriate, its capability to make quantitative assessments of the environmental effects of cruise-altitude emissions, and will monitor and assist, as possible, other research programs, both here and abroad.
