Abstract Description: This presentation will cover the unique analysis and evaluations completed for an airport runway rehabilitation project using the FAA’s Aviation Environmental Design Tool (AEDT). A large major hub airport in the US was planning to schedule a full rehabilitation of one of it’s main departure runways. The runway rehabilitation would be accomplished in stages, two of the stages with a limited runway length and one stage with a complete runway closure. The limited runway length stages allowed for limited operations on the runway. Due to the phased construction approach and length of the closure a full Environmental Assessment (EA) was required by the FAA. The EA included a full aircraft noise analysis and Emission Inventory for the EA. Development of the aircraft model inputs and results of the modeling will be discussed along with input options. The presentation will present the development of the runway use and taxi times for each construction phase and how those inputs effected the modeling results. The noise results and assumptions used to develop the aircraft emission inventory will be discussed. The aircraft emission inventory will be shown along with how to interpret the model results for this type of project. FAA regulations will be summarized and noise impacts on the community will be discussed.
