  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 air
taxi traffic within New York City by replacing a portion of the city's taxi
requests with trips taken with electric vertical takeoff and landing vehicles
and evaluate the sensitivity of passenger trip time to a variety of system wide
assumptions. In particular, the paper focuses on the impact of the passenger
capacity, landing site vehicle capacity, and fleet size. The operation density
is then compared with the current air traffic to assess operation constraints
that will challenge the network UAM operations.
