Airline operations
Published in Gert Meijer, Fundamentals of Aviation Operations, 2020
These operations require high investments in equipment, referred to as Ground Service Equipment (GSE). High loaders, conveyor belts, trucks with dollies, luggage carts, catering trucks, water & waste trucks, Ground Power Units, engine starters and pushback vehicles are part of the GSE that is needed for aircraft handling. Inside the terminal, often in the basement, luggage sorting and screening infrastructure is required. Inside the terminal, the airline may need check-in counters, customer services desks, self-boarding devices and luggage drop-off devices, all connected to the airline IT infrastructure. The airline may need a business class lounge, and hub airlines need transfer desks and services in the secured area of the terminal. Airlines need to buy, lease or rent all this for their home-base ground operations.

Airports are an essential hub for not only global long-distance flights but also for medium-distance travels to neighboring countries or domestic destinations. From large extended facilities to small-sized airport buildings, the value chain of serving the needs of air transportation consists of similar actors and units, such as the departing and arriving facility, airlines and their aircraft, ground support equipment and agents, air traffic control, as well as airplane maintenance service (Schmitt & Gollnick, 2016). All these components at an air transport system lead to several local and global impacts. On the one hand, the society benefits from an increase of the gross domestic product as well as regional and international involved parties grow economically. On the other hand, crucial negative environmental and social impacts result from the operation of an airport. These include effects to local communities like noise, land use, ground traffic congestion, and global environmental effects (Janić, 2011b).
Fundamental study of corrosion-preventive compounds: part III—soft films
Published in Corrosion Engineering, Science and Technology, 2020
Corrosion-preventive compounds (CPCs) are used widely as an additional and temporary corrosion protection measure in aircraft applications and ground support equipment in the aerospace industry [1,2]. CPCs can be categorised as hard, soft or waxy films [1]. Hard film CPCs are generally used on non-moving parts, such as bare metals or damaged painted panels. Soft or waxy film CPCs are more often used on lap joints. Various commercial CPCs exhibit different properties and are used for different applications. However, there is a lack of fundamental knowledge regarding the factors that control the performance of CPCs, which limits the development of improved CPCs. The compositions of commercial CPCs are trade secrets, so simple evaluation of various commercial CPCs provides no understanding regarding the role of their ingredients.

Aluminum 7075 bars of 40 mm diameter were used for experimentations. It is very strong since zinc is the predominant alloying agent. It’s one of the strongest aluminum alloys in the market, and it’s similar to a variety of steels. It is frequently utilized in high-stress applications, such as aircraft wing spars and ground support equipment, due to its great strength. The major elements of the raw material are represented in Table 1.[33]
