Catering Personnel clear the galley areas immediately after disembarkation of the incoming passengers. After the galley has been cleaned, it is restocked, and a secondary cleaning takes care of spillage during restocking. Internationally agreed standards of hygiene must be met in the handling of food and drink from their point of origin to the passenger. Where route stations are unable to meet either quality or hygiene standards, catering supplies are often brought from the main base. Figure 6.16 shows the loading operation of a catering truck. These trucks are usually constructed from a standard truck chassis with a closed van body that can be lifted up by a hydraulic scissor lift powered by the truck engine. Two different types of catering trucks are available low-lift vehicles suitable for servicing narrow loading wide bodied jets.
