ACRP Research Report 164: Exhaust Emissions from In-Use General Aviation Aircraft
Abstract
The Aviation Environmental Design Tool (AEDT) uses emissions data for various aircraft engines, and there is great confidence in the data for large commercial aircraft engines. For smaller aircraft, such as piston- and small turbine-powered aircraft, emission factor data are either non-existent or have not been independently verified, which can result in under- or overestimating aircraft emissions and can make it difficult for airports with significant general aviation (GA) operations to characterize their emissions inventories. Under ACRP Project 02-54, emissions were measured from 47 engines while those engines were in use. Data obtained as part of this research are available on the TRB website and can be added to the FAA’s AEDT database of aircraft engines so as to better understand and estimate GA aircraft emissions. ACRP Research Report 164 provides the findings from the emissions testing and the data.
