ABSTRACT
In the future, the demand for air traffic services
will not only increase but also will likely shift from
scheduled operations towards more unscheduled
operations for air taxi, charter, fractional
ownership, and on-demand small low-cost aircraft.
As the metropolitan areas continue to grow, the
satellite airports around major hubs will provide a
wide range of flight options for people to fly
between their homes and places of business or
pleasure. This paper describes an air transportation
system’s architecture concept and a vision of the
future operating environment based on industry
trends for air traffic demand and aviation
technology enhancements. A multi-facet airport
infrastructure is developed to support suburbandirect,
spoke-to-spoke, and intra/inter-city Vertical
Short Take Off and Landing (VSTOL) operations.
A multi-level Communication, Navigation and
Surveillance (CNS) architecture is presented that is
intended to assure robustness and seamless
coverage. The future Air Traffic Management
(ATM) system architecture considers end-to-end
traffic flow planning and control by National,
Regional and Local facilities with a redefined role
of service providers as strategic planners and
tactical controllers. In spite of a majority of aircraft
equipped with enhanced avionics capable of flying
4D Navigation and strategically separated, the
operational concepts presented are designed to also
provide service to less equipped General Aviation
(GA) aircraft as well as the Uninhabited Aerial
Vehicles (UAV). Modeling and simulation results
are presented illustrating the potential growth in
future demand and fleet mix at 30 major airports,
as well as airborne/ground movement delays at
these airports.
