This excess tra#c often results in delays and compromised safety. Therefore, a number of initiatives to improve airport capacity and throughput have been proposed. However, in order to assess the impact of these technologies on commercial air tra#c one must move beyond the vehicle to a system-ofsystems point of view. This top-level perspective must include consideration of the aircraft, airports, air tra#c management and airlines that make up the airspace system. In addition to the analysis of each of these components and their interactions, a thorough investigation of capacity and throughput technologies requires due consideration of other pressures such as economics, safety and government regulations. Furthermore, the air tra#c system is inherently variable with constant changes in everything from fuel prices to the weather. Thus, the development of a modeling environment to be u...

Military budget cuts and increased competition in the commercial market have shifted the focus of aircraft design to include affordability concerns. This has resulted in the need for increased knowledge in the early stages of design when a high percentage of the available resources are committed. The Technology Identification, Evaluation and Selection methodology outlined herein provides the designer with a structured decision making method within which technological alternatives can be compared. Furthermore, this methodology is probabilistic in nature to account for the uncertainty and risk inherent in design, as well as for the variability of the aerospace market. Thus, this seven-step process leads the designer from a societal need, through a series of alternatives, to a robust solution capable of meeting customer goals within a variable environment. As a proof of concept the methodology wa...

Although significant efforts have been made toward collaboration and synchronization, additional work is required to harmonize capabilities, terminology, assumptions, standards, and implementation schedules. This paper presents a rigorous approach and visual environment to instantaneously examine and compare the components of both European and American programs and to further identify and understand the nature of their relationships. In particular, it provides a unique and interactive means to investigate and compare both programs, roadmaps, terminologies, and definitions.
