Advanced Air Mobility encompasses emerging aviation technologies that transport people and cargo between local, regional, or urban locations that are currently underserved by aviation and other transportation modalities. The disruptive nature of these technologies has pushed industry, academia, and governments to devote significant investments to understand their impact on airspace risk, operational procedures, and passengers. A flexible framework was designed to assess the operational viability of these technologies and the sensitivity to a variety of assumptions. This framework is used to simulate an initial AAM implementation scenario in New York City. This scenario was created by replacing a portion of NYC taxi requests with electric vertical takeoff and landing vehicles. The framework was used to assess the sensitivity of this scenario to a variety of system assumption.
