“…An extensive review of literature evolved that this objective is achievable by various means (Singh et al , 2018, 2019a). From past studies (Agarwal, 2012; Lee, 2010; Müller et al , 2018), it is evident that the responsibility of fuel efficiency improvement relied upon “superior aircraft designs” (F1) supported by “incorporation of advanced technologies” (F2). Technology use has revolutionized every sphere of aviation and is still progressing.…”

“…Under increasing air travel demand, flying at the best profile with optimal characteristics may not be possible for each aircraft. However, “efficient aircraft operations” (F6) supported by “implementation of revolutionary strategies” (F7) can help in avoiding extra fuel burn (Agarwal, 2012; Brueckner and Abreu, 2017; Reynolds, 2015; Schlumberger, 2012). None of the above measures and factors may succeed if these are not encouraged by society and policymakers.…”

Purpose In the past four decades, substantial air traffic growth has triggered enthusiasm in the aviation sector. At the same time, this growth has posed challenges to its financial and environmental sustainability commitments. A buzz has been centered on introducing and supporting aviation sustainability initiatives. These challenges have led to acknowledging the need to reduce aviation fuel consumption, a function of multiple factors. The different stakeholders having a diverse type of interplay govern the effective implementation of the factors at different decision levels (strategic, tactical and operational). Thus, the present study aims to critically examine various decision levels involved to understand opportunities and requirements related to aviation sustainability. Design/methodology/approach In this study, the best–worst method is used to quantify different decision levels’ role on various factors affecting aviation fuel consumption. Findings The results of this study signify that tactical-level decisions are most influential in reducing aviation fuel consumption with the highest impact (0.41) followed by operational-level decisions (0.30) and strategic-level decisions (0.29), respectively. Research limitations/implications The results point toward the critical role of middle-level hierarchy, i.e. aircraft manufacturers, airlines and others in the aviation industry’s sustainable growth. Thus, middle-level stakeholders must be inspired and empowered to act, being at the center they link the other two levels. Originality/value This study has added to the body of knowledge by exploring the decision-making competencies needed by different aviation sector stakeholders. It also presents the possible options available in the sector and the role of stakeholders at different levels in exploiting and implementing the sustainable aviation sector changes.

The Cyber-Physical System (CPS) is a term describing a broad range of complex, multidisciplinary , physically-aware next generation engineered system that integrates embedded computing technologies (cyber part) into the physical world. In order to define and understand CPS more precisely, this article presents a detailed survey of the related work, discussing the origin of CPS, the relations to other research fields, prevalent concepts, and practical applications. Further, this article enumerates an extensive set of technical challenges and uses specific applications to elaborate and provide insight into each specific concept. CPS is a very broad research area and therefore has diverse applications spanning different scales. Additionally, the next generation technologies are expected to play an important role on CPS research. All of CPS applications need to be designed considering the cutting-edge technologies, necessary system-level requirements, and overall impact on the real world.

“…The importance of reducing the environmental impact of aviation has been fully realized by many governments and private industry; and many researchers have started efforts to address the environmental concerns [3][4][5]. Words such as green or sustainable are coined to describe future aircraft or aviation with reduced environmental impact.…”

Most forecasts predict an annual airline traffic growth rate between 4.5 and 5% in the foreseeable future. To sustain that growth, the environmental impact of aircraft cannot be ignored. Future aircraft must have much better fuel economy, dramatically less greenhouse gas emissions and noise, in addition to better performance. Many technical breakthroughs must take place to achieve the aggressive environmental goals set up by governments in North America and Europe. One of these breakthroughs will be physics-based, highly accurate and efficient computational fluid dynamics and aeroacoustics tools capable of predicting complex flows over the entire flight envelope and through an aircraft engine, and computing aircraft noise. Some of these flows are dominated by unsteady vortices of disparate scales, often highly turbulent, and they call for higher-order methods. As these tools will be integral components of a multi-disciplinary optimization environment, they must be efficient to impact design. Ultimately, the accuracy, efficiency, robustness, scalability and geometric flexibility will determine which methods will be adopted in the design process. This article explores these aspects and identifies pacing items.
