Currently, when modeling either aircraft noise or emissions with the Aviation Environment Design Tool (AEDT), there are simplifications associated with the methodology suggested for determining the aircraft gross takeoff weight and the inability to model reduced thrust/power departures. The goal of this project was to develop a functional relationship between stage/trip length and weight that could improve the existing guidance provided for weight estimation. This work also determined the percentage of departures that use reduced thrust and the level of reduced thrust that is used when the takeoff weight is such that reduced thrust departures are possible.
