Today, many small aerodromes struggle with financial difficulties, and a large cost is air traffic control. Remote tower centers, which remotely provide air traffic services to aerodromes, can help reduce this cost. Each center may contain a number of remote tower modules, where each module is manned by a controller that can handle one or more aerodromes. In this paper we present the remote tow...

This paper gives a visit report from the baggage handling halls at Vienna International Airport together with texts about image processing applications at airports. The paper is the final written document for the excursion group in the course “Applications of Image Processing” at Vienna University of Technology. The foci in the technical texts are on illumination, configuration (environment), s...

A 2010 Government Accountability Office (GAO) study reported nearly 40 percent of all delays occurring in the National Airspace System (NAS) were caused by New York airports. In this paper, however, a local network analysis of the NAS elucidates New York’s delay phenomena as multifaceted. Furthermore, a graph theory measure, node strength, is used to analyze directed weighted graphs representin...

Abstract The increase of frequency and severity extreme weather events due to climate change gives evidence severe challenges faced by infrastructure systems. Among them, the aviation sector is particularly at risk from potential consequences change. Airports are classified as critical infrastructures because they provide fundamental functions sustain societies economic activities. More specifi...

We analyze the influence of increases in airport capacity and the entry of low-cost carriers on airline competition. We use parametric and non-parametric techniques to analyze a sample of Spanish routes. We find that capacity increases in large airports produce more competitive airline conduct only in routes departing from non-hub airports. Also, we find that the natural monopoly threshold decr...

Business intelligence in a future global air traffic management can be accomplished via integrated and intelligent operational decision support technology for airports and airline operators, air traffic controllers and pilots. It aims to support decisions regarding the management and the control of the global traffic flows, of the capacity of the airports and of the global air space-time resour...

(4804 words, including abstract) Abstract. In the United States, most airports do not place any limitations on airline schedules. At a few major airports, the current scheduling restrictions (mostly administrative measures) have not been sufficiently strict to avoid consistent delays and have raised debates about both the efficiency and the fairness of the allocations. With a forecast 1.1 billi...

Delay propagation is a well-known phenomenon within the global air transportation system. Specifically, because of equipment and crew connectivity, a flight delayed early in the day can induce delays to multiple flights later in the day. In this paper we investigate this phenomenon by developing a statistical model that predicts the average flight delay after a given breakpoint time b, based on...

Airport runways and taxiways have been identified as a key source of system-wide congestion and delay in the over-strained commercial air traffic system. To combat this growing problem, we present a novel approach for taxiway scheduling and traversal. Aircraft must traverse a taxiway, represented by a graph, from gates to their respective runways and arrive at their scheduled times while adheri...

ing from the Project Control Group approach used by Brisbane Airport Corporation Limited (BACL), two features have particular economic significance. First, the Project Control Group is open to all airlines and involves itself very early in the development of investment proposals. Airlines are consulted in the design stage, and continue to participate through to the post completion review stage....
