Klomp, R.E. (author)THE increasing demand in worldwide air travel is foreseen to push the limits of capacity of the current Air TrafficManagement (ATM) system within the coming decade. Therefore, twomajor international programs have been initiated to fundamentally restructure the way in which Air Traffic Control (ATC) is performed. A key pillar in both programs is...doctoral 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

Ribeiro, M.J. (author)Increasing delays and congestion reported in many aviation sectors indicate that the current centralised operational model is rapidly approaching saturation levels. Air Traffic Control (ATC) system is not expected to keep pace with the ever-increasing demand for air transportation. Its capacity is still limited by the available controllers, and...doctoral thesis 2023

Tielrooij, M. (author)Future concepts for Air Traffic Management (ATM) foresee—and even mandate—an increase in the distance from the destination airport at which the ATM system should start planning the arrival sequence and arrival time of inbound flights. By increasing the horizon beyond one hour before arrival, it becomes possible to timely adjust the flight path...doctoral thesis 2022

Aalberse, Max (author)During the COVID-19 pandemic people living close to the airport got accustomed to less flights, and therefore less noise disturbance. Now the amount of traffic is increasing again and so is the noise disturbance. For this research specifically the optimizing task of distributing of arriving aircraft over the IAF is addressed, as often the...master thesis 2022

Nyessen, Nino (author)In an effort to increase the operational efficiency in the North Atlantic region, the benefits of a decentralized, wind-optimal routing structure are researched. Such a routing structure allows for direct routing by optimizing trajectories on the individual level. Implementing a tactical conflict detection and resolution method eliminates the...master thesis 2022

Oosterhof, Edzer (author)The airspace in western Europe is one of the most complex airspaces globally. With the air space already operating near maximum capacity, innovations are needed to increase airspace efficiency. This research aims to design and test a debunching concept for inbound air traffic to increase the efficiency of the arrival traffic stream. A...master thesis 2022

Kloosterman, Luc (author)In the future, Air Traffic Controllers are expected to work together with more advanced computer-based automation that can automatically take action. The main challenge is then how to design computer-based tools such that they foster acceptance among air traffic controllers. One possible approach to foster acceptance is by matching the automated...master thesis 2022

Badea, C. (author), Groot, D.J. (author), Morfin Veytia, A. (author), Ribeiro, M.J. (author), Dalmau, Ramon (author), Ellerbroek, J. (author), Hoekstra, J.M. (author)Air traffic demand has increased at an unprecedented rate in the last decade (albeit interrupted by the COVID pandemic), but capacity has not increased at the same rate. Higher levels of automation and the implementation of decision-support tools for air traffic controllers could help increase capacity and catch up with demand. The air traffic...conference paper 2022

Ribeiro, M.J. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Future operations involving drones are expected to result in traffic densities that are orders of magnitude higher than any observed in manned aviation. Current geometric conflict resolution (CR) methods have proven to be very efficient at relatively moderate densities. However, at higher densities, performance is hindered by the...journal article 2022

IJtsma, Martijn (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)Air traffic controller workload is a limiting factor in the current air traffic management system. Adaptive support systems have the potential to balance controller workload and gain acceptance as they provide support during times of need. Challenges in the design of adaptive support systems are to decide when and how to trigger support. The...journal article 2022

Ribeiro, M.J. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Current predictions on future drone operations estimate that traffic density orders of magnitude will be higher than any observed in manned aviation. Such densities redirect the focus towards elements that can decrease conflict rate and severity, with special emphasis on airspace structures, an element that has been overlooked within...journal article 2022

Ribeiro, M.J. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Current predictions for future operations with drones estimate traffic densities orders of magnitude higher than any observed in manned aviation. Such densities call for further research and innovation, in particular, into conflict detection and resolution without the need for human intervention. The layered airspace concept, where aircraft...journal article 2022

de Rooij, G. (author), Tisza, A. B. (author), Borst, C. (author), van Paassen, M.M. (author), Mulder, Max (author)In the quest for more efficient air traffic management, a common approach is to allocate an increasing amount of functionality to higher levels of automation, with a supervisory role for humans. This potentially leads to forthcoming issues such as skill degradation and out-of-the-loop phenomenon. If the traffic in an airspace is instead shared...conference paper 2022

Wiechers, Stephanie (author)This study has researched what are defining factors on the attitude toward a new technology within the group of Area Control (ACC) at Luchtverkeersleiding Nederland (LVNL) and how these factors shape an Air Traffic Controller’s (ATCo) attitude toward the technology in an exploratory way. The outcomes of the research suggest that dominant factors...master thesis 2021

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

Kestens, Lisa (author)Due to the continuous growth of air traffic up to the year 2020, the air transportation network has become more complex, and the airports and airspace busier. However, capacities have not grown at the same rate as air traffic, making Air Traffic Control one of the most encountered primary delays. A data driven approach is taken in order to...master thesis 2021

Metz, I.C. (author)Bird strike prevention in civil aviation has traditionally focused on the airport perimeter. Since the risk of especially damaging bird strikes outside the airport boundaries is rising, this PhD thesis researches the safety potential of operational bird strike prevention involving pilots and controllers. In such a concept, controllers would be...doctoral thesis 2021
