At the designated time during the
flight, the cabin crew then carry out the service of meals, snacks and other items.
Upon arrival at its destination, each aircraft is then stripped of all the equipment and
trolleys, which are returned to the production units for cleaning and re-use. In
achieving this, it is necessary to understand the impact of flying on the physiology of
the passenger, to manage a complex supply chain, ensure the safety and quality of
the product, utilise increasingly sophisticated information and communication
technologies, and engage in on-going research and development.
