System-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 کامل2000: Hybrid-system Simulation for National Airspace System Safety Analysis
Analysis of large, complex systems requires simulations of hybrid-system dynamics, i.e., dynamics which are best described by a combination of continuous-time and discrete-event models, and their interactions. To serve as valuable research tools, such simulations need also be computationally efficient, readily modifiable, and open to a wide range of component modules. This paper describes the d...
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 کاملFeedback 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...
