Abstract:The mass of particulate matter (PM) emitted from aircraft must be predicted for major
actions at airports to comply with current federal regulations. However, this PM mass in
the jet exhaust has not been effectively quantified to permit accurate emission factors to
be developed. Certification methodologies are based on the Smoke Number (SN), which
was essentially implemented to eliminate the visible exhaust of aircraft but does not
provide needed mass emission factors. A literature review was conducted for the FAA,
and based on available data and findings developed a first order approximation (FOA)
method. This derived methodology had to have the flexibility to permit differences in
fleet mix, aircraft modes (throttle settings), and airport altitudes to be considered. The
accuracy of each possible method and the availability of data also were heavily weighed
when considering this approximation method. The development of this methodology and
preliminary evaluation are presented in this paper.
