Abstract:

The emissions from in-use commercial aircraft engines have been analyzed for selected gas-phase species and particulate characteristics using continuous extractive sampling 1-2 min downwind from operational taxi- and runways at Hartsfield-Jackson Atlanta International Airport. Using the aircraft tail numbers, 376 plumes were associated with specific engine models. In general, for takeoff plumes, the measured NOx emission index is lower (~18%) than that predicted by engine certification data corrected for ambient conditions. These results are an in-service observation of the practice of reduced thrust takeoff. The CO emission index observed in ground idle plumes was greater (up to 100%) than predicted by engine certification data for the 7% thrust condition. Significant differences are observed in the emissions of black carbon and particle number among different engine models/technologies. The presence of a mode at ~65 nm (mobility diameter) associated with takeoff plumes and a smaller mode at ~25 nm associated with idle plumes has been observed. An anticorrelation between particle mass loading and particle number concentration is observed.
