"TRB's Airport Cooperative Research Program (ACRP) Report 86: Environmental Optimization of Aircraft Departures: Fuel Burn, Emissions, and Noise explores a protocol for evaluating and optimizing aircraft departure procedures in terms of noise exposure, emissions, and fuel burn. Included with the print version of the report is a CD-ROM that contains the spreadsheet-based Departure Optimization Investigation Tool (DOIT) that allows users to understand and test tradeoffs among various impact measures, including noise levels, rate of fuel consumption, and emissions."--Publisher's description.
