Updated Recommendations for Modifications to the AEDT for Improved Noise Modeling of Advanced Air Mobility Vehicles

Urban Air Mobility (UAM) vehicles are an up-and-coming technology in the realm of commercial aviation. As with any other flying vehicle operating in the vicinity of people, how the noise these vehicles create impacts local communities must be investigated and understood. The Federal Aviation Administration (FAA) Aviation Environmental Design Tool (AEDT) is the required tool for performing noise and emissions studies for compliance with the National Environmental Policy Act (NEPA). This tool allows the modeling of fixed-wing and helicopter vehicles, but it does not specifically support UAM vehicle modes. This TM documents the final set of recommendations to the FAA from NASA's Revolutionary Vertical Lift Technology (RVLT) project for improving the AEDT for modeling UAM vehicles using either of the pre-existing fixed-wing or helicopter modes.
