“…Therefore, with a constant Fig. 1: Overview of a CDA trajectory flight path angle, the last parameter, the flap schedule, which has been subject to modification and optimization [6], [11], remains fixed, since it is preferred to keep flap deployment velocities at a narrow range for the convenience of the pilots [29]. In addition, when flaps are extended close to their corresponding maximum operating velocities, it can lead to extensive wear.…”

With this report, my Master studies, which started in September 2018 and were spent between The Netherlands, Germany and Greece, come to an end. Starting with my courses, I had the chance to substantiate my background in the domain of Control & Simulation through the lectures of motivating Professors and the assignments that made me grow individually, but also as a team member, by tackling diverse challenges. Then, during my Internship in Max Planck Institute for Biological Cybernetics, I had the unique opportunity to work in a renowned research institution and expand my horizons. I would like to firstly thank Prof.dr.ir. M. Mulder for bringing me in contact with my Internship Supervisor in February 2019, then in February 2020 providing me with this interesting and multifaceted Thesis topic and being eager to guide and assist me through this project. It was a privilege to discuss together the development of my project during our weekly group calls. Moreover, I was grateful to work on this project under the supervision of Dr.ir. C. Borst and Dr.ir. M. M. van Paassen, who I had the chance to meet at first in their insightful lectures during my first year in TU Delft. I really appreciated to hear their points of view and getting ideas of ways to move forward. In addition, I would like to thank Dr.ir. A. C. in 't Veld for providing a pilot's perspective into this project and Ir. O. Stroosma and ing. E. H. H. Thung for their assistance during the experimental period. I would like also to express my gratitude to my friends and roommates, in both Athens and Delft, who supported me during the challenging times of my studies. Last but not least, I would like to thank my family, who was always standing by my side during this demanding journey and providing me with the means to accomplish my goals.

“…There have been many developments for meeting Time Of Arrival (TOA) requirements which involved deflection of flaps / slats continuously which posed difficulties for operation by pilots [3,4,6,7,8]. In this regard, Sopjes and team came up with Free Degree Decelerating Approach (FDDA) [5,6] which avoids continuous deflection of flaps.…”

Air traffic has grown over the last few decades and is increasing further to a state where many airports and especially big hubs are reaching their limits of capacity. Hence many research activities were initiated to come up with more efficient and safe flight operations including Flight Path Boundary approach for controlling Time-of-Arrival in the terminal area. The design studies presented in this paper investigate a simplified representation of an intermediate flight path in the Vertical Situation Display for meeting the Time-of-Arrival requirements. A guidance law for maintaining constant EAS during descent has been evolved to adjust the thrust based on variation of air data measurements. Simulation results for typical case studies are presented to validate the approach. Possible areas for further extension are highlighted.

“…Three Degree Decelerating Approach (TDDA) 4 consists of continuous deceleration at 3 degree glide slope. Free Degree Decelerating Approach (FDDA) 8 and Vertical Flight-path angle Approach (VFA), 6 allow for variable glide slopes with different schedules for velocity profiles. Comparatively, little work along these lines has been performed with GA applications in mind.…”
