5、h aircraft food service. GAIN (e.g., beverage maker, oven) is not an integral part of the galley and is removable from the galley without tools or with the use of simple tools. The design and operation of GAIN has a significant impact on cabin service, cabin safety and workload of the crew members.

6、Most types of GAIN have significant electrical power consumption, are connected to the aircraft potable water system, and are controlled by electronic devices. This AS specifies criteria to assure safe GAIN design and function.FOREWORDThis SAE Aerospace Standard (AS) and the SAE AS8056 “Minimum Desi

However, references to these considerations are included as appropriate. c. Fully addre

28、ss requirements that are covered by national aviation regulations, pertinent U.S. Public Health regulations and/or design details, which should be covered by galley operator/airplane manufacturer specifications for the subject equipment.d. Fully address requirements for equipment utilizing hydraulic

29、 systems (e.g., Trash compactors). 1.2.3 When the term “equipment” is used in this standard, it refers to all of the items identified in the Purpose (1.2) unless specifically identified otherwise. 1.3 Mandating and Recommendation Phrases a. “Shall” The word “shall” indicates a mandatory criterion. b

30、. “Should” The word “should” indicates a criterion for which an alternative, including non-compliance, may be applied if it is documented and justified. SAE AS8057 - 6 -2.
