A team of Systems Engineering students at George Mason University have developed an initial design for an integrated system, the Airport Departure Arrival Management System (ADAMS), which provides information and decision support capabilities to air traffic managers, ground controllers, and National Central Flow Control. The objective of ADAMS is to decrease the net arrival-departure delay for a network of airports by leveraging high fidelity weather forecasts, capacity optimization algorithms, and ground sequencing guidance. This paper presents the results of the design efforts, with a brief look at functional architecture, and preliminary simulation results to evaluate the impact of ADAMS on net flight delay and network stability in a six-node network of airports.
The Federal Aviation Administration (FAA) and industry are moving towards a more flexible, user orientated air traffic control system. The question is: does this point to a natural evolution or revolution in the world ofthe air traffic controller? The National Airspace System (NAS) is, by all accounts the safest in the world. How will we sustain this record of performance with increased flexibility and user involvement? How will controllers and pilots react to a new more dynamic paradigm? Is the current state of automation, modeling, and analysis what is needed to make Free Flight a reality? How will FAA insure that all human factors questions are answered before implementation? How will we quantify the impact of unanswered questions and their influence on safety? These, and many more questions need to be answered to ensure that the benefits promised by Free Flight are realized by all parties. The National Air Traffic Controllers Association (NATCA) supports the new concept. Yet, we are seriously concerned about the actual implementation of Free Flight's various components.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
