Handbook for evaluating emissions and costs of APUs and alternative systems

"This report provides a handbook to help airports evaluate different alternatives to aircraft auxiliary power units (APUs). The handbook addresses environmental impacts, costs, infrastructure and maintenance requirements, as well as funding options. The accompanying CD-ROM, CRP-CD-113, "Tool for Evaluating Emissions and Costs of APUs and Alternative Systems (TEECAAS)," provides a user-friendly software tool that can be used to quantify emissions from APUs and alternative systems, while also providing quantitative analysis of the financial implications of implementing and operating the systems. While the handbook provides the overall evaluation guidance including step-by-step details of the quantification process, the tool facilitates the quantification work. The handbook and software tool can be used by airports of all sizes, whether or not they have collected airport-specific data. Such specific information includes airport temperature ranges, operations by aircraft category, the amount of time aircraft spend at gates, power requirements, and various other datasets. In those cases where airport-specific data are not available, the included set of default data can be used. The resulting emissions, power requirements, and costs can be used to analyze various airport scenarios. The handbook and tool are intended to be used for planning purposes only, and should not be used to replace or supersede the use of the Federal Aviation Administration's (FAA's) Aviation Environmental Design Tool (AEDT)."--Publisher description.
