“…This is mainly due to the lack of public available data from aircraft manufacturers. In fact, only one peer-reviewed paper performing a complete LCA of an aircraft was found [44] and one from an aircraft's wing [50], while the remaining works originate from theses and reports [40,45,51,52]. There are also a few available publications focusing on the comparison between metallic alloys and lightweight materials from an environmental point of view [38,39,53].…”

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 resources used and related environmental impacts, to derive recommendations regarding recycling, and to analyze the influence of increasing utilization of lightweight composite materials in aircraft manufacturing. It was identified that the engine is the structure containing resources with the highest scarcity, with tantalum dominating seven of the eleven analyzed impact categories. Aluminum, titanium, and nickel were shown to lead to the highest environmental impacts. Hotspots in the criticality and environmental assessment often occur due to alloying resources with a low mass share. It was shown that aluminum and steel alloy recycling should be prioritized. A higher lightweight composite material share in the aircraft increases impacts in the categories climate change and fossil resource depletion by 12% and 20%, respectively, whereas the impact of the category acidification, political stability, and demand growth decreases by 16%, 35%, and 60%, respectively.

“…Later, what determines the lifetime of an airplane is the ability of its parts to resist short-term elements external (corrosion) to loads (hard landings, strong turbulent, etc.) and repeated normal loads (fatigue) [29] [30].…”

In aircraft project management, reliability and maintainability are fundamental for ensuring system safety, for optimizing the manufacturing process and for improving assembly/disassembly operations when maintenance actions are required. The inclusion of such requirements helps to minimize life cycle costs, augments the residual lifetime of aircraft and consequently increases customer satisfaction. While most papers published in the aircraft engineering literature are rather evasive or do not accurately describe the role of reliability and maintainability (RM) methods in early design phases, this paper elucidates the problem. This paper discusses various concepts such as design for reliability and risk assessment analysis for improving aircraft safety and reliability at the deployment stages. The article also focuses on how reliability prediction issues are addressed using various methods, tools and standards, such as failure modes and effect analysis, fault tree analysis and guidelines such as MIL-STD-217f and ARP4754. Finally, this paper demonstrates that reliability is crucial to consider in all phases of the life cycle of an aircraft.

“…Through Life Cycle Assessment (LCA), Natural Fibre Polymer Composites (NFPC) have been demonstrated to have higher environmental performance when used in the automotive industry (Joshi et al 2004;Le Duigou and Baley 2014), mainly due to the lower density of natural fibres; which translates into lower emissions resulting from fuel combustion. The potential application of these type of composites in the aviation sector has been addressed in the work of Bachmann et al (2017), Vieira andBravo (2016) &Vidal et al (2018).…”

“…Other studies do not even document if co-products are generated nor the exact inventory data that are considered (e.g. Vieira and Bravo 2016). The study of Deng and Tian (2015) is a notable exception where an effort to document the actual co-products fate was made, but it suffers from a major misunderstanding of the agricultural phase of the feedstock.…”

As part of the efforts to reduce the environmental impacts caused by the aviation sector, the use of bio-based instead of fossil-based materials has been assessed as a possible mitigation option. Natural Fibre Polymer Composites have proven to have a higher environmental performance in the automotive sector and are emerging as an option for weight reduction in aircraft. This study quantifies, though Life Cycle Assessment, the environmental performance of specific flax-based composite panels intended for aircrafts as interior fitting elements (i.e. partition panels, tray tables, baggage compartments) compared to a glass fibre/epoxy composite with a honeycomb core. Through system expansion, the fate of co-products issued from the production of the flax fibre technical textile used as reinforcement in the biocomposite material were considered in the assessment. Results showed that for an application in the aeronautics sector, the weight of the panels is the upmost critical parameter shaping the overall environmental performance of panels. Focusing on the panel production only, the biocomposite panel showed a higher environmental performance in the categories of climate change and marine eutrophication compared to the conventional panel, and the fire suppressant agent was identified as the main contributor to the environmental impacts of the bio-based panel. Yet these gains were negligible when considering the full life cycle of the panels, due to the higher weight (14%) of the bio-based panels; which is linked to the bio-based panel being at a prototype stage.In order to improve the environmental performance of the biocomposite panel and thus reduce its weight, it was shown relevant to optimize geometry of the panel itself, especially its core, so less resin could be used.
