Abstract:

A survey was made to 1 measure ozone concentrations in CAR 4b jet aircraft cabins and cockpits on flights above 25,000 ft to obtain a 12-month evaluation with emphasis on seasonal and meteorological correlation and 2 locate and chart ozone-enriched air masses to obtain further correlations and to find any abnormal conditions that result in high ozone concentration. The data obtained by monitoring jets showed 1 External ozone enters via the pressurization system. 2 Ozone concentration varies with altitude, latitude, and season. 3 Pressurization systems of various aircraft do not differ in ozone-decomposing efficiency. 4 Internal ozone concentration is negligible on flights made below the tropopause.
