Assessment of particulate matter (PM) emissions from aircraft operations at airports is growing in importance as demand for air travel grows. Although there is increasing information on aircraft main engine PM emissions, little or no PM data are available for on-aircraft auxiliary power unit (APU) emissions, and tire and brake emissions during landing operations. To address this lack of data, a measurement campaign for quantifying and characterizing PM emissions from these sources is needed.
The objective of this research is to design and implement a measurement campaign of PM emissions from a representative set of in-service aircraft APUs as well as PM emissions associated with aircraft brake and tire wear that occurs during landing. The data should include PM mass and size and consider PM number and chemical composition.
Research is complete. Results are available as: ACRP Report 97.
