COVID-19 arrived in the world suddenly and unexpectedly. It caused major disruptions at economical, operational and other levels. In the case of flight traffic, the operations were reduced to 10% of their original levels. The question after COVID-19 is how to restart the operations and how to keep the …

This work focuses on humidity effects of turbofan engines, in order to identify the magnitude of the error in operational conditions and the implications on maintenance decision support. More specifically, this paper employs a set of different methods, including semi-empirical corrections used in engine …

In recent years, there has been a large increase in the use of uncrewed attack aircraft, or attack drones, in the Yemen conflict. At the same time, the flight endurance and payload capabilities of these uncrewed aerial vehicles seem to have increased significantly. This article presents a flight performance …

Russian disinformation has thus far proven to be unconvincing for most Dutch target audiences. This is the conclusion of the present chapter. Information and disinformation have become effective weapons in international politics. This is part of a development where the weapons and concepts used in deterrence …

This study is written to explore which in-flight service components influence the passenger satisfaction according to passengers who have taken a long-distance flight of a full-service airline from Schiphol Airport in Amsterdam. Since very few studies have been conducted to understand the influence of …

The operations of take-off and landing at hub airports are often subject to a wide variety of delays; the effects of these delays impact not only the related stakeholders, such as aircraft operators, air-traffic control unity and ground handlers but as part of the European network, delays are propagated …

Airport management is regularly challenged by the task of assigning flights to existing parking positions in the most efficient way while complying with existing policies, restrictions and capacity limitations. However, such process is frequently disrupted by various events, affecting punctuality of …

This paper describes the concept of a new algorithm to control an Unmanned Aerial System (UAS) for accurate autonomous indoor flight. Inside a greenhouse, Global Positioning System (GPS) signals are not reliable and not accurate enough. As an alternative, Ultra Wide Band (UWB) is used for localization. …

Rotor morphing has been investigated in the past for improvement of rotor performance, either for reduction of rotor power demand or for vibratory load alleviation. The present study investigates the application of camber morphing for improvement of rotor performance in hover and vertical flight conditions, …
