This study proposes a systems-level approach to airport and runway availability assessments and prediction, and addresses the problem of the aging or continuously degrading aviation infrastructure. Although the availability block diagrams are often used in the availability assessment of aerospace and electronic systems, their application to the airport availability problem on a systemlevel, dev...
The busiest European and US airports are still a major bottleneck in the air transportation network. Optimizing utilization of existing airport capacity during periods of congestion, to maximize the airport throughput and minimize delays, is a challenging task. It is important for both strategic (several hours into the future) traffic flow management (TFM) and tactical air traffic control (ATC)...
Most flight delays are created by imbalances between demand and capacity at the busiest airports. Absent large increases in capacity, airport congestion can only be mitigated through scheduling interventions or improved capacity utilization. This paper presents an integrated approach that jointly optimizes the airport’s flight schedule at the strategic level and the utilization of airport capac...
This document describes operations associated with a set of flight experiments and demonstrations using a Boeing757-200 (B-757) research aircraft as part of low visibility landing and surface operations (LVLASO) research activities. To support this experiment, the B-757 performed flight and taxi operations at the HartsfieldAtlanta International Airport (ATL) in Atlanta, GA. The B-757 was equipp...
The general increase in air traffic and the complexity of modern airport layouts have led to think about new system opportunities to assist pilots during maneuvers on airport surface. Two applications will be considered in this paper: guidance and control. Guidance application provides indication to the pilot to navigate on the airport surface whereas control application provides steering indic...
Since 1969, 63 cases of airport malaria have been reported in Western Europe, 24 of which occurred in France. Most were due to Plasmodium falciparum. In 1994, 7 cases occurred in and around Roissy Charles de Gaulle airport (CDG), showing 4 types of contamination: among employees working on airstrips or opening containers, among residents living near the airport, among people living at some dist...
conclusions the results of this study led to the identification of many of the errors and conditions that affect the performance of controllers, providing the ability to define safety and ergonomic interventions to reduce the risk of human error. therefore, the results of this study can be a basis for planning atm to prioritize prevention programs and safety enhancement results the analysis of ...
This paper presents a novel approach based on statistics and probability theory to improve Air Traffic Flow Management (ATFM) efficiency. This tool allows air traffic controllers to organize a more efficient air traffic flow pattern for strategic and tactical planning. Firstly, a procedure to establish a strategic arrival schedule is developed. An implicit feature of this probabilistic procedur...
European transport policy promotes intermodality as a means of improving efficiency and sustainability. This study looks into passenger air-rail intermodality at airports which are directly integrated into long-distance rail networks and focuses on intermodal journeys in which the rail trip doesn’t serve the purpose of city-centre to nearby airport access, but rather makes up a substantial leg ...
As more metropolitan areas approach " non-attainment " status for ozone, air pollution at airports is becoming an increasingly important topic. Most proposed emissions reduction strategies target passenger automobiles and airport ground service equipment (GSE). At many airports, the future growth in oxides of nitrogen (NOx) emissions from aircraft is likely to offset any reduction achieved from...
