Feedback Control of the National Airspace System
This paper proposes a general modeling framework adapted to the feedback control of traffic flows in Eulerian models of the National Airspace System (NAS). It is shown that the problems of scheduling and routing aircraft flows in the NAS can be posed as the control of a network of queues with load-dependent service rates. We can then focus on developing techniques to ensure that the aircraft qu...
متن کاملEfficient Simulation of the National Airspace System
The National Airspace System (NAS) is a large and complicated system. Detailed simulation models of the NAS are generally quite slow, so it can be difficult to obtain statistically valid samples from such models. This paper presents two methods for reducing the complexity of such networks to improve simulation time. One method is removal of low-utilization queues – that is, replacing a queueing...
متن کاملBrief History of the National Airspace System
• Approximately 48,000 FAA employees who provide air traffic control, flight service, security, field maintenance, certification, systems acquisitions, and a variety of other services. • Approximately 13,000 instrument flight procedures, including over 1,000 Instrument Landing System (ILS) procedures, over 1,700 nondirectional beacon (NDB) procedures, over 2,700 VHF omnidirectional range (VOR) ...
متن کاملSystem-level Prognostics for the National Airspace
In the National Airspace System (NAS), safety is assured through a set of rules, regulations, and procedures to respond to unsafe events. However, safety stands to benefit immensely from the introduction of tools and methodologies from Prognostics and Health Management (PHM). PHM will enable the NAS to stochastically predict unsafe states within the NAS, enabling a proactive preventative respon...
متن کاملAn Airspace Concept Evaluation System Characterization Of National Airspace System Delay
This paper presents an analysis of National Airspace System (NAS) delay. An interacting set of models called the Airspace Concept Evaluation System (ACES) was used to simulate one day of NAS-wide air traffic. A total of 36 simulations were run. They included nine different airport capacity conditions across the NAS and four levels of NAS-wide demand. The analysis of delay results for these 36 s...
