Gheorghe, Andrada (author)Predicting aircraft Take-Off Weight (TOW) has been a long-sought task by aviation stakeholders, especially for operational and regulatory bodies involved in flight planning. Unfortunately, TOW being a sensitive parameter to operational trends and cost indices, aircraft operators tend to keep it confidential. In recent years, Machine Learning (ML...master thesis 2024

van Dillen, Bob (author)The introduction of Trajectory Based Operations (TBO) is set to change the operation on all levels of Air Traffic Control (ATC), including aerodrome control. Here, adherence to a planned four-dimensional trajectory is important to achieve a stable operation. At the same time, this concept provides possibilities for support tools to be used in...master thesis 2024

Vos, Reinier (author)Air traffic sector demand and capacity balancing is an important process to enable safe and efficient flight execution. In current operations, demand and capacity are determined based on schedules and flight plans. In reality, disruptions to flights create a different situation that may not have been anticipated by the Air Navigation Service...master thesis 2023

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

Zou, Y. (author), Borst, C. (author)To facilitate a smooth integration of drones into the current Air Traffic Management (ATM) system, Unmanned Air Traffic Management (UTM) systems, services and protocols are currently under development. Unlike current ATM, UTM will rely on high levels of automation. This is potentially problematic, because 100% safe and reliable automation under...conference paper 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

Zhu, X. (author), Hong, Ning (author), He, Fang (author), Lin, Yu (author), Li, L. (author), Fu, Xiaowen (author)The terminal airspace that surrounds an airport is the area with high flight density and complex structure. Aircraft are asked to follow the standard arrival and departure routes in terminal airspace, yet the actual trajectories may deviate due to air traffic control (ATC) instructions, pilots' decisions, surveillance and flying performance...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

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

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

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

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
