This paper describes an augmented reality prototype that precisely tracks the position of paper flight strips used by air traffic controllers. By embedding resistors with different values into slightly modified plastic stripholders and inserting contacts along the sides of a stripboard frame, we can detect the exact position of individual stripholders (and their corresponding paper flight strip...

Since critical socio-technical systems include people interacting with equipments in workplaces, their intrinsic reliability problems have been concerned with both these two “actors”. Air Traffic Control (ATC) is going to be such a system in which controllers use a large number of distributed software tools to provide safety ATC services. The reliability of these services relies on the availabi...

Availability of measures that would predict controller success in his or her task and the impact of changing procedures and advancing technology on the system as a whole is imperative to the success of modernization of air traffic control (ATC) systems worldwide. This paper describes a database that is populated by the results of previous reviews of ATC research literature, organized according ...

In this paper, we consider optimal resolution of air traffic conflicts. Aircraft are assumed to cruise within a given altitude layer, and are modeled as a kinematic system with velocity constraints and curvature bounds. Aircraft can not get closer to each other than a predefined safety distance. For such system of multiple aircraft, we consider the problem of planning optimal paths among given ...

A different paradigm is needed for real-time command and control (C&C) problems. Past approaches, using multiprocessors (MP), for real-time computing have had great difficulty in meeting real problem requirements. We review some reasons why C&C problems that require a solution on a MP architecture may be intractable, and then show an architecture where these reasons for intractability are nonex...

The ability to provide flexible, automated management of air traffic is critical to meeting the ever increasing needs of the next generation air transportation systems. This problem is particularly complex as it requires the integration of many factors including, updated information (e.g., changing weather info), conflicting priorities (e.g., different airlines), limited resources (e.g., air tr...

due to increasing growth of air traffic, it is very important to have a reliable air traffic control system. usually secondary surveillance radar systems are employed for this task. in this paper, a new approach is presented to identify interrogators location of this system. the proposed method works passively and uses just a single receiver. this goal has been reached using angle and time diff...

The air transportation system infrastructure is comprised of communication, navigation, surveillance, and air traffic management systems, and is known as the National Airspace System. This chapter describes the current very high-frequency and high-frequency modes of communication, very high-frequency omnidirectional range, distance measuring equipment, and instrument landing systems for navigat...

The Federal Aviation Administration (FAA) is one of the largest Air Navigation Service Providers, managing air traffic for more than 15% of the world’s airspace. Today’s Air Traffic Control (ATC) system cannot meet the growth of the air traffic activities, which brings with more unprecedented delays. At the same time, Air Traffic Controllers are facing higher workload than ever before. The FAA ...

Over the next 10 years a major controversy developed over whether the Federal Reserve recognized or placed enough emphasis on its responsibility for controlling the growth of the money stock. The related question of which operating strategy to follow in controlling the money stock was pushed to the background. Economists can argue at great lengths over the extent to which the Federal Reserve tr...
