The current US administration plans to protect the entire territory of the United States against any potential air or missile attack. The focus is on deploying large satellite constellations capable of detecting and intercepting long-range missiles shortly after launch. Even if only a fraction...

Since its launch in 2022 the Clean Aviation Joint Undertaking (CAJU) has been at the forefront of pioneering technologies that are driving the sustainable aviation revolution, working towards the sector's target of achieving climate neutrality by 2050.

Urban Air Mobility (UAM) beschreibt den kommerziellen Personentransport in der Luft, in oder zwischen Städten und ländlichen Gebieten, mittels eVTOL-Vehikeln (electric vertical take-off and landing vehicles). UAM wird ein großes Potenzial prognostiziert, weil die eVTOL-Vehikel effizienter,...

This investigation combines the aircraft maintenance routing problem (AMRP) with the aircraft maintenance facility location problem as they are interdependent. Unlike the classical fixed charge location model, aircraft maintenance facility location is not based on static customer demands but on...

Establishing (e.g., perfecting) and enforcing a lien presents technical pitfalls and practical problems with which practitioners and courts are often unfamiliar or uncomfortable. After all, the law of liens requires an understanding of many different areas of the law, including the law of...

The aviation industry faces many challenges. One of which is unprepared aircraft maintenance graduates taking licensure exams. Students preparing for CAAP licensure examination typically return to their undergraduate school to ask their technical instructors to train them for their incoming...

In this paper, we investigate optimization of an aircraft maintenance routing problem (AMRP), which is currently a hot research topic in the air transport industry. The optimization of AMRP can help airline companies improve their management capacity and operational efficiency. However, there...

The global aircraft fleet has been expanding worldwide, leading to a high demand for primary resources. Simultaneously, recycling initiatives for decommissioned aircraft are still incipient. Following circular economy principles, the aims of this paper are to identify potentially critical...

Convective weather poses a major threat that compromises the safe operation of flights while inducing delay and cost. The aircraft trajectory optimization problem under thunderstorms is addressed, proposing a novel heuristic approach that incorporates uncertainties in the evolution of convective...

Spare parts inventory management represents a challenge for aircraft companies. Determining the optimal allocation and consumption of spare parts is problematic due to the intermittent demand. Original equipment manufacturer (OEM) uses different models to evaluate inventory stock level to avoid...

Due to the dynamic development of environmentally friendly aircraft propulsion, the paper describes the effect of distributed propulsion on the emission and fuel consumption changes of aircraft in comparison to aircraft with traditional propulsion. The analysis was based on the technical data of...

Abstract Modern commercial aircraft can experience significant solar loading during turnaround when the aircraft is stationary on the tarmac. With the increased usage of composite materials, a change in the aircraft thermal environment results due to the substantial difference in metal and...

The durability of the transportation capital stock slows down the pace of decarbonization since newer vintages feature cutting-edge technology. If older vintages were to be retired sooner, the social cost of travel would decline. This paper analyzes and explores the viability of a potential...

Using a sample of commercial aircraft transactions, the paper decomposes the raw fire sale discount on sales of aircraft by distressed airlines into three components: (i) quality impairment due to under-maintenance, (ii) misallocation to lower productivity users, and (iii) a liquidity component...

Warren Buffett famously commented that the US airline industry had made zero profit in its first nine decades. Subsequently, between the millennium and the Great Financial Crisis the airlines in total lost almost $60bn. Yet no major airline was liquidated or taken over in those nine years....
