FOREWORD By Christine L. Gerencher Staff Officer Transportation Research Board ACRP Report 9: Summarizing and Interpreting Aircraft Gaseous and Particulate Emissions Data provides a summary of a series of government-sponsored aircraft emissions tests that were undertaken to gain a better understanding of gaseous and particulate emissions from aircraft engines. Copious amounts of data were collected as part of this scientific effort, known as the Aircraft Particle Emissions eXperiment (APEX) tests and Delta Atlanta Harts- field test. This report summarizes the data gathered in these studies to help the airport community and general public understand how the data can be used to develop better air quality assessments in the airport environment. The APEX and Delta Atlanta Hartsfield series of tests were a collaborative scientific research effort of the National Aeronautics and Space Administration (NASA), the Federal Aviation Administration (FAA), the Environmental Protection Agency (EPA), and the De- partment of Defense (DoD). Their main objective was to advance the understanding of particulate emissions by characterizing gaseous and particulate emissions from various in- service commercial aircraft engines. The participants in these tests performed an extensive set of measurements aimed at examining the effect of engine operating and ambient atmo- spheric conditions on emissions; simulating emissions at airports; and studying fuel effects on particulate emissions by varying fuel composition. The first APEX test was conducted in April 2004 to collect a set of gaseous and particu- late emissions data from a DC-8 aircraft with CFM-56-2C1 engines owned by NASA. This test was followed by the Delta Atlanta Hartsfield Study in September 2004 where two MD-88 aircraft with JT8D engines, two B757 aircraft with PW2037 engines, and two B767 aircraft with CF6-80 engines were examined. A third test in August 2005 examined emissions from two B737-700 aircraft with CFM56-7B22 engines and two 737-300 aircraft with CFM56-3B1 engines and a fourth test, conducted in October-November 2005, evaluated emissions from a Learjet25 aircraft with CJ610 engines, an A300-600 aircraft with PW4158 engines, two B757 aircraft with RB211-535E4B Phase 5 engines, an ERJ aircraft with AE3007- A1E engines, an ERJ aircraft with AE3007-A1P engines, and a B737-300 aircraft with CFM56- 3B engines. In addition to the gaseous and particulate emissions measurements from static aircraft tests, there were two occasions when aircraft taxi and take off emissions were measured downstream of an active runway during normal airport operations. One of these was at Oakland International Airport during the second APEX test, known as JETS-APEX2, and the other was at Hartsfield Jackson Atlanta International Airport during the Delta Atlanta Hartsfield Study. These sets of data afforded surveys of the particulate and gaseous emis- sions of a wide range of aircraft.
Substantial gaseous and particulate emissions data have been obtained from this series of tests, at a cumulative cost of almost $4 million. This report summarizes the extensive data and analyses of the test results to provide clarification for the airport community and gen- eral public on how the data can and cannot be used in the development of local air quality analysis.
