  The United Nations has long put on the discussion agenda the sustainability
challenges of ur- banization, which have both direct and indirect effects on
future regulation strategies. Undoubtedly, most initiatives target better
quality of life, improved access to services & goods and environment pro-
tection. As commercial aerial urban transportation may become a feasible
research goal in the near future, the connection possibilities between cities
and regions scale up. It is expected that the growing number of vertical
takeoff & landing vehicles used for passenger and goods transportation will
change the infrastructure of the cities, and will have a significant effect on
the cityscapes as well. In addition to the widely discussed regulatory and
safety issues, the introduction of elevated traffic also raises environmental
concerns, which influences the existing and required service and control
infrastructure, and thus significantly affects sustainability. This paper
provides narrated overview of the most common aspects of safety, licensing and
regulations for passenger vertical takeoff & landing vehicles, and highlights
the most important aspects of infrastructure planning, design and operation,
which should be taken into account to maintain and efficiently operate this new
way of transportation, leading to a sustainable urban air mobility ecosystem.
