Modifying and Using Default GSE Emissions Model Data 43 developed. This chapter presents these data that are intended to be used in place of the default data currently in AEDT or in the event that airport-specific data cannot be collected due to time or resource constraints.

Modifying and Using Default GSE Emissions Model Data 49 5.2.1.4 Non-Gate GSE Operating Times There are some types of GSE that also operate while away from the gate when traveling between gates or between gates and the terminal. These GSE mainly comprise baggage/cargo tugs, cabin service/catering/lavatory trucks, and fuel trucks.

Modifying and Using Default GSE Emissions Model Data 51 As a means of accounting for deicing GSE operational times and their resultant emissions, Table 15 provides some default deicing TIM values for use in the absence of airport-specific values. These data were derived by observing aircraft deicing activities recorded on video (see Table 14)

52 Improving Ground Support Equipment Operational Data for Airport Emissions Modeling An airport's GSE fleet size and make-up can be estimated using this method from the number of annual commercial aircraft operations at the airport. Figure 19, from ACRP Report 78, provides the computed relationships between commercial aircraft operations and the corresponding GSE fleet size at the study airports.
