van Selling, Stijn (author)The Dutch Air Traffic Control has implemented fixed approach trajectories within approach control during night operations when traffic density is low. During the day, when traffic density is higher, vector-based operations are used. The Dutch Air Traffic Control aims to implement fixed approach trajectories when traffic density is high. This...master thesis 2023

Marinescu, M. (author), Olivares, Alberto (author), Staffetti, Ernesto (author), Sun, Junzi (author)This paper addresses the problem of spatiotemporal wind velocity field estimation for air traffic management applications. Using data obtained from aircraft, the eastward and northward components of the wind velocity field inside a specific air space are calculated as functions of time. Both short-term wind velocity field forecasting and wind...journal article 2023

Marinescu, Marius (author), Olivares, Alberto (author), Staffetti, Ernesto (author), Sun, Junzi (author)This work addresses the problem of vertical wind profile online estimation at a given location. Specifically, the north and east components of the wind are continuously estimated as functions of time and altitude at two waypoints used for landing on the Adolfo Suarez Madrid-Barajas airport. A continuous nowcast of the wind profile is...journal article 2022

Kool, Brent (author)Automatic Dependent Broadcast-Surveillance (ADS- B) was introduced to increase the safety of air travel. Since then it has proven to be a useful source of air traffic data for academic research because it is publicly available. Another source of information are the communications between air traffic control (ATC) and aircraft. Methods are (being...master thesis 2021

Sun, Junzi (author), Marinescu, M. (author), Olivares, Alberto (author), Staffetti, Ernesto (author)Accurate wind information is crucial in air traffic management, for instance, to improve trajectory predictability and precision in controlled time of arrival. Nowadays, air traffic management relies on Numerical Weather Prediction, which usually has a low resolution and low update rate. A potential approach for improving the resolution and...conference paper 2021

Olive, Xavier (author), Sun, Junzi (author), Murça, Mayara Condé Rocha (author), Krauth, Timothe (author)Aircraft trajectory generation is a widely addressed problem with applications including emergency trajectory generation, collision risk models, air traffic flow and capacity management or airspace design. State of the art methods to generate individual trajectories and optimise some performance or emergency criterion may lack of realism with...conference paper 2021

Marks, Tobias (author), Dahlmann, Katrin (author), Grewe, V. (author), Gollnick, Volker (author), Linke, Florian (author), Matthes, Sigrun (author), Stumpf, Eike (author), Swaid, Majed (author), Unterstrasser, Simon (author)The aerodynamic formation flight, which is also known as aircraft wake-surfing for efficiency (AWSE), enables aircraft to harvest the energy inherent in another aircraft’s wake vortex. As the thrust of the trailing aircraft can be reduced during cruise flight, the resulting benefit can be traded for longer flight time, larger range, less fuel...journal article 2021

Yamashita, Hiroshi (author), Yin, F. (author), Grewe, V. (author), Jöckel, Patrick (author), Matthes, Sigrun (author), Kern, Bastian (author), Dahlmann, Katrin (author), Frömming, Christine (author)Climate-optimized routing is an operational measure to effectively reduce the climate impact of aviation with a slight increase in aircraft operating costs. This study examined variations in the flight characteristics among five aircraft routing strategies and discusses several characteristics of those routing strategies concerning typical...journal article 2021

Metz, I.C. (author), Ellerbroek, Joost (author), Mühlhausen, Thorsten (author), Kügler, Dirk (author), Kern, Stefan (author), Hoekstra, J.M. (author)Involving air traffic controllers and pilots into the bird strike prevention process is considered an essential step to increase aviation and avian safety. Prior to implementing operational measures such as real-time warning systems, it is vital to evaluate their feasibility. This paper studies the efficacy of a bird strike advisory system for...journal article 2021

Lührs, Benjamin (author), Linke, Florian (author), Matthes, Sigrun (author), Grewe, V. (author), Yin, F. (author)Air traffic contributes to anthropogenic global warming by about 5% due to CO<sub>2</sub> emissions and non-CO<sub>2</sub> effects, which are primarily caused by the emission of NO<sub>x</sub> and water vapor as well as the formation of contrails. Since-in the long term-the aviation industry is expected to maintain its trend to grow,...journal article 2021

van Wijngaarden, Dennis (author)This research presents the derivation, implementation and safety assessment of a velocity obstacle- based conflict resolution method to be used by UAVs flying within a horizontally restricted airspace by a geofence under the presence of wind. Two parameters indicating the safety of the applied conflict resolution method have been measured, i.e.,...master thesis 2020

Groenen, Remco (author)Socio-technical systems consist of deeply interconnected and interdependent social entities and technical systems that collaborate to achieve a global goal. The individual characteristics and behaviours of each involved actor and their interactions define the resulting overall emergent system behaviour. Due to increased complexities in socio...master thesis 2020

Schyns, Claire (author)In the current economy, many airports are operating close to their maximum capacity with high utilisation rates. This raises the need for airports to implement demand management measures. This need is further exacerbated when the capacity is further limited due to weather-based capacity shortfalls. Therefore, the development of an Evaluation...master thesis 2020

Ottenhoff, Matthijs (author)As a result of the current evolution in the ATM system, a fundamental shift in the ATC work domain is foreseen from ad-hoc tactical to more strategic, 4D (i.e., space and time) trajectory management. Both the SESAR programme in Europe<br/>and the NextGen programme in the US envision a central role for the human operator, to be aided by high...master thesis 2020

Janowski, Jakub (author)The resilience of the Air Traffic Management (ATM) system to disturbances is required to maintain high operation performance. Before it can be improved, the resilience of the ATM system must be quantified. The measurement of resilience requires knowledge of a system reference state. This thesis proposes a novel methodology to detect disruptions...master thesis 2020

Fines, Konstantine (author), Sharpanskykh, Alexei (author), Vert, M.P.J. (author)Airport surface movement operations are complex processes with many types of adverse events which require resilient, safe, and efficient responses. One regularly occurring adverse event is that of runway reconfiguration. Agent-based distributed planning and coordination has shown promising results in controlling operations in complex systems,...journal article 2020

Itoh, Eri (author), Mitici, M.A. (author)This paper proposes to analyze control strategies for arrival air traffic at an airport using a classical queuing model. The parameters of our model are estimated by means of a data-driven analysis of two years of radar tracks and flight plans for arrival flights at Tokyo International Airport from 2016 to 2017. Our results show that increasing...journal article 2020

(author)Collisions between birds and aircraft pose a severe threat to aviation and avian safety. To understand and prevent these bird strikes, knowledge about the factors leading to these bird strikes is vital. However, even though it is a global issue, data availability strongly varies and is difficult to put into a global picture. This paper aims...review 2020
