Although airport ground support equipment (GSE) can provide significant contributions to an airport’s overall emissions, little guidance is available to help airports accurately capture actual GSE activity at their facilities in a manner suitable for the Federal Aviation Administration’s (FAA’s) approved emissions models, Emissions and Dispersion Modeling System (EDMS) and the Aviation Environmental Design Tool (AEDT). This can result in inaccurate predictions of air quality impacts because staff may use insufficient or inconsistent data collection, analysis, and reporting methods. Conversely, airports often choose not to collect specific GSE activity data and instead use default values established in EDMS and AEDT. However, these default values are widely acknowledged to be conservative and may overestimate an airport’s air quality impacts. This report is a guidance document that provides a potential update to the current set of default GSE fleet and activity data used for passenger and cargo aircraft and a protocol to improve the accuracy and consistency of data collection for airport GSE activity compatible with EDMS and the AEDT. This guidance document can be used by airport operations, environmental and planning personnel, and other stakeholders for the purpose of understanding and improving local air quality. The updated set of default GSE fleet and activity values address the number and type of vehicles by aircraft code; difference between type of operations; time in operational mode; and gate deicing vehicles. The airport-specific data-gathering protocol includes the parameters to be collected; recommendation of statistically valid sample sizes; operational considerations for start-up and mobilization of equipment; coordination with airlines; and safety considerations. The guidance is tailored to airports of different sizes; airports of different climates; limitations of the current default GSE fleet; various fueling methods; availability and utilization of aircraft parking position utilities; and is applicable to newer aircraft.
