Simulators play an important role in cabin crew training. While pilots train in simulators that replicate the flight deck, flight attendants train inside a section of an aircraft cabin and galley. The cabin crew training simulator can move in a way that mimics turbulence and can even fill with smoke for training in how to manage onboard fires.
Introduction
Published in Yatish T. Shah, Modular Systems for Energy and Fuel Recovery and Conversion, 2019
One of the most important ways for airlines to differentiate from competitors and to gain market shares is the aircraft cabin. The aircraft producers have to offer individual cabin layouts. The resulting internal complexity has major consequence for any aircraft manufacturer’s design and production processes. Furthermore, the innovation cycle of aircraft cabins is significantly shorter than that of airframes. Therefore, almost every aircraft cabin is unique [36]. At the same time, airplane manufacturers increase their production rates due to rising worldwide demand. This results in an increased importance of standardization and mass customization to reduce production costs for the aircraft manufacturers and total cost of ownership for the airlines [41].

Ultrahigh molecular weight polyethylene (UHMWPE) fiber is light, resistant to chemical corrosion, and a superior flame retardant (Chhetri & Bougherara, 2021). UHMWPE fiber exhibits excellent mechanical properties, such as high tensile strength, impact resistance, shear resistance, etc. (Yan et al., 2020a). Furthermore, UHMWPE fiber is a high-performance fiber with the highest specific strength and specific modulus. UHMWPE fiber has a low density, only half the density of carbon fiber, and the quality and volume of the composites prepared from UHMWPE fiber are low; however, the mechanical properties are considerably enhanced. As one of the hottest materials, UHMWPE is widely used in bulletproof vests (Qu et al., 2020; Shen et al., 2019), buildings (Hossein Hamedi et al., 2020; Shao et al., 2018), aerospace industry (Shanmugam et al., 2020), medicine (Duraccio et al., 2019; Hassanein et al., 2020; Senatov et al., 2020), and other fields. Noise reduction in the aircraft cabin is crucial, and noise levels in the aircraft cabin largely determine the competitiveness of airlines. Achieving satisfactory vibration isolation and noise reduction is an essential subject in aviation aircraft design (Anoshkin et al., 2015). Tire and engine noise are key indices for evaluating vehicle performance when a car is in motion. Developing acoustic absorbing materials that provide comfortable driving conditions for passengers has attracted considerable attention in the automobile industry (Sung et al., 2016). Consequently, it is imperative to investigate the acoustic absorption properties of UHMWPE.

Civil aircraft manufacturing industry is an important pillar of industry for the national economy. The traditional civil aircraft manufacturing enterprises are experiencing transformation from providing civil aircraft products to providing the civil aircraft services across the entire life cycle (Kesseler 2006). In the process of transformation and upgrading, a well-developed knowledge management system is crucial to support the rapid and agile development of enterprises, fast delivery of orders and improvement of the user experience (Yu et al. 2008). It is widely believed that high effectively use of company’s design knowledge is essential to achieve sustainable competitive advantage (Wang, Suihuai, and Ting 2017). The aircraft cabin is the main place that users’ interaction behaviour happened with the products, and the design of aircraft cabin is the soul of civil aircraft manufacturing and the most important part of civil aircraft design (Kesseler 2006). Design knowledge management plays a key role to shorten the product development cycle and improve the efficiency of product development (Tang 2018).
Recommendations to maintain immune health in athletes
Published in European Journal of Sport Science, 2018
Athletes are also exposed to environmental stress outside of training. For example, during long-haul air travel, which is common for elite athletes (Figure 1), hypobaric-hypoxia in the aircraft cabin exposes athletes to altitudes equivalent to 1800−2400 m (Wilder-Smith et al., 2012). This coincides with studies reporting a two-to-five-fold increase in URI symptoms with long-haul travel (Schwellnus et al., 2012; Svendsen et al., 2016). Studies are required to determine whether the increase in URI symptoms with long-haul travel is due to hypoxia-induced immune alterations, increased exposure to pathogens in the aircraft cabin, or some other mechanism. It is quite conceivable that the increase in psychological stress, anxiety and travel fatigue associated with long-haul travel to training camps and competitions may increase URI. For example, athletes may experience anxiety related to fear of flying, flight delays and baggage issues; they may also experience travel fatigue related to sleep loss and jet lag.
