This research investigates the role of time prediction accuracy in optimizing Continuous Descent Operations (CDO) within the aviation sector, with a specific focus on assessing the additional benefits brought forth by the integration of Air-Ground Datalink technologies. Continuous Descent Operations, characterized by uninterrupted and efficient...

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...

As aviation recovers to pre-pandemic levels large amounts of Air Traffic Flow Management delay also return, as the traffic at airports and in airspaces reaches their old levels. These delays have a yearly cost of around 500 million euros in the European Civil Aviation Conference area and are detrimental to the experience of passengers. This...

For future operations of unmanned aviation, even higher traffic densities than previously seen in manned aviation are expected. Previous work has shown that a vertically layered airspace design performs best at improving safety metrics such as the total number of conflicts and Losses of Separation (LoSs). Furthermore, it has been shown that...

In order to enable the safe and efficient integration of Unmanned Aerial Vehicles into very low level airspace, modern day research focuses on the development of new traffic services and procedures. One of these is the geovectoring protocol, which aims to reduce traffic complexity by setting limits on the allowed ground speed, course, and...

To facilitate an increase in air traffic volume and to allow for more flexibility in the flight paths of aircraft, an abundance of decentralized conflict resolution (CR) algorithms have been developed. The efficiency of such algorithms often deteriorates when employed in high traffic densities. Several methods have tried to prioritize certain...

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...

Radio frequency fingerprinting has been identified as a method to increase integrity in aircraft surveillance while retaining its openness. One way to uniquely determine transmitting devices is to distill the device its radio frequency (RF) fingerprint by looking at the physical features of the message signal it transmits. This physical layer...

Airspace’s increasing demand is a current concern without a solution. Different research projects aim to expand its available capacity by improving software performance, for example, concerning trajectory prediction and conflict detection methods. This research contributes to this goal by investigating the effect of different look-ahead time...

The International Air Transport Association (IATA) and the European Commission (EC) have stated their desire for the aviation industry to reach net zero carbon emissions by 2050 and in addition these emissions must be reduced by 45% in 2030. In order to reach these goals, all possible contributions to a reduction in carbon emissions are...

Testing novel concepts in the allocation and use of aircraft is commonly done in air traffic simulators. Current day simulators rely on proprietary models and often propose questionable solutions. This paper uses BlueSky as simulator, in cooperation with performance models OpenAP and BADA. BlueSky aims to provide the user with full freedom to...

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...

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...

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...

Several initiatives are being developed to shift the current paradigm in Air Traffic Management (ATM) from the tactical-based approach to more strategic-based coordination of flights. This transformation of the ATM system relies on the improvement of predictive models that predict the 4D-trajectory of an aircraft. Previous studies primarily...

Aarts, Michiel (author)
The traffic density of small aerial vehicles operating within urban environments is expected to increase significantly in the near future. This urban environment is highly constrained due to being limited to the low-altitude airspace directly above the existing road network. To increase understanding of the factors influencing the capacity of...

Taxi time predictions are used by air traffic controllers to optimally release aircraft from the gate such that efficiency losses due to queuing are minimized, while runway capacity is maintained. More accurate taxi times can therefore result in improved airport surface operations and reduce air traffic controller workload. This article proposes...

In recent years Amsterdam Airport Schiphol (AAS) has been the airport with the highest Airport Air Traffic Flow Management (ATFM) delay in Europe. EUROCONTROL delays inbound flights heading towards AAS on departure, due to reasons at or around AAS. There are two main reasons for Airport ATFM delay at AAS, Weather and Aerodrome Capacity. This...

The applicability of conflict rate models to controlled, structured, terminal airspace is investigated. A collision rate model is adapted to conflicts between flows of aircraft, and its validity is empirically confirmed. Conflicts are divided into between-flow conflicts and within-flow conflicts. Applicability to a terminal airspace without...

The Compound Annual Growth Rate (CAGR) of the aviation industry is predicted to be 4.1% from 2015 to 2045 [23].In recent years, however, increasing public pressure has been put on the industry to further reduce noise and carbonemissions. This can be done by eliminating all horizontal flight segments during the approach phase, reducing theaverage...
