ACRP Report 97: Measuring PM Emissions from Aircraft Auxiliary Power Units, Tires, and Brakes
Abstract
ACRP Report 97: Measuring PM Emissions from Aircraft Auxiliary Power Units, Tires, and Brakes presents the results of a comprehensive test program designed to measure particulate matter (PM) emissions from auxiliary power units (APUs) and from tires and brakes during the landing phase of operation of in-service commercial aircraft. While significant emissions data exist for aircraft main engines, only limited data have been available for APUs, and no data existed for PM emissions produced during landing by tires and brakes. The research results, therefore, provide a significant contribution to the characterization of emissions from these sources. The data obtained from the test program were used to develop PM emission indices for APUs and tires. Providing such data will allow airports to improve the accuracy of their PM emissions inventories.
