QUANTITATIVE SAFETY ASSESSMENT OF AIR TRAFFIC CONTROL SYSTEMS THROUGH SYSTEM CONTROL CAPACITY
… of developmental changes in safety critical systems like the Air Traffic Control (ATC) systems. Effectiveness of the assessments is particularly desirable today in the safe implementations of revolutionary ATC overhauls like NextGen and SESAR. QSA of ATC systems are however challenged by …

A comparison of capacity and delay values between parallel and intersecting runway configurations at a major airport
… of runways were utilized for arrival aircraft operations at a major airport. The Federal Aviation Administration's Delay Simulation Model was employed to determine capacity and delay values so that a conventional runway configuration could be compared with the fanway approach. Various …

Human-centered systems analysis of mixed equipage in ocean air traffic control
… the oceans are currently available. However, all aircraft operators will not equip simultaneously because of the high costs required. Consequently, as these CNS systems are integrated into oceanic air transportation architecture, the controller will have to manage the current low frequency …

Information inference for cyber-physical systems with application to aviation safety and space situational awareness
… on sensors and processors, engineering systems have become more complex and highly automated to meet ever stringent performance and safety requirements. These systems are usually composed of physical plants (e.g., aircraft, spacecraft, ground vehicles, etc.) and cyber components (e.g., …

Deriving new measurements for real-time reactive systems
Real-time reactive systems are largely event-driven, interact intensively and continuously with the environment through stimulus-response behavior, and are regulated by strict timing constraints. Examples of such systems include alarm systems, air traffic control systems, nuclear reactor control …

Time-Based Collision Risk Modeling for Air Traffic Management
… have driven a steadily increasing demand for air transportation. Increasing density of aircraft operating in a finite volume of airspace is accompanied by a corresponding increase in the risk of collision, and in response to a growing number of incidents and accidents involving collisions …

On Capacity Estimation and Capacity-Safety Relationship in an Air Transportation Network
Air transportation is a complex system of interlinked distributed networks in which different components have their own constraints and performance measures. For example, an airport network in which each airport is treated as a node and models the departures/arrivals of flights as links considers …

The causes and consequences of divergence between the air traffic controller state awareness and actual system state
… research investigated divergence potential in air traffic controllers and identified controller divergence causes and consequences. Based on this investigation, approaches to minimize controller divergence and its consequences were identified for current air traffic control systems and future …

Optimal runway exit design and capacity enhancement
Congestion and delay problems at airports have received much attention in recent years because of the unbalanced condition between demand and supply. Recent demand forecasts indicate that the problems are expected to increase in the next decade. Relieving congestion of the air transportation …

State estimation and sensor selection in discrete event systems modeled by Petri nets
… irregular intervals, of physical events. Such systems arise in a variety of contexts, such as energy distribution networks, computer and communication networks, automated manufacturing systems, air traffic control systems, highly integrated command, control, communication, and information (C3I) …
