Sun, Junzi (author), Hoekstra, J.M. (author), Ellerbroek, Joost (author)Air traffic simulations serve as common practice to evaluate different concepts and methods for air transportation studies. The aircraft performance model is a key element that supports these simulation-based studies. It is also an important component for simulation-independent studies, such as air traffic optimization and prediction studies....journal article 2020

van Baelen, D. (author), Ellerbroek, Joost (author), van Paassen, M.M. (author), Abbink, D.A. (author), Mulder, Max (author)Modern aircraft use a variety of fly-by-wire control devices and combine these with a flight envelope protection system to limit pilot control inputs when approaching the aircraft limits. The current research project aims to increase pilot awareness of such a protection system through the use of force feedback on the control device, i.e.,...conference paper 2020

van Baelen, D. (author), Ellerbroek, Joost (author), van Paassen, M.M. (author), Mulder, Max (author)Modern fly-by-wire aircraft use flight envelope protection systems, whose actions are not always clear to pilots. To promote situation awareness, proximity to the limits of the flight envelope can be communicated using haptic feedback, by providing forces through the control device. Such a system was developed and this paper reports on the...conference paper 2019

Rudnyk, I. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)To facilitate the increasing amount of air traffic, current and future decision support tools for air traffic management require an efficient and accurate trajectory prediction. With uncertainty inherent to almost all inputs of a trajectory predictor, the accurate prediction is not a simple task. In this study, Monte Carlo simulations of a...journal article 2019

Metz, I.C. (author), Mühlhausen, Thorsten (author), Ellerbroek, Joost (author), Kügler, Dirk (author), Hoekstra, J.M. (author)This paper presents a collision avoidance algorithm to prevent bird strikes for aircraft departing from an airport. By using trajectory-information of aircraft and birds, the algorithm predicts potential collisions. Collision avoidance is performed by delaying departing aircraft until they can follow a collision-free trajectory. An...conference paper 2019

Sun, Junzi (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)The Automatic Dependent Surveillance-Broadcast (ADS-B) data has become one of the most popular sources of data for trajectory-based ATM studies. It is can be received in most of the world without restrictions. Extended coverage can be achieved with a network of low-cost receivers and satellites. However, the fact that ADS-B is designed to...conference paper 2019

Analysis of Conflict Resolution Methods for Manned and Unmanned Aviation Using Fast-Time SimulationsRibeiro, M.J. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)In the coming years, aviation will have to cope with an increase in the number of aircraft, and of drones purchased in the open market. The human intervention of Air Traffic Management (ATM) will be overburden with guaranteeing flight safety with hundreds of manned aircraft and Unmanned Aerial Vehicles (UAVs) operating simultaneously. Conflict...conference paper 2019

Metz, I.C. (author), Muhlhausen, Thorsten (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Bird strikes have the potential to cause severe damage to aircraft. Therefore, measures to reduce the risk of bird strikes are performed at airports. However, this risk is not limited to the airport but is increased in the arrival and departure corridors as well. Consequently, a significant amount of bird strikes occurs outside the direct...abstract 2018
