"This SAE Aerospace Recommended Practice (ARP) provides the industry agreed methods to keep the center of gravity (C.G.) location of loaded air cargo Unit Load Devices (ULDs) within the maximum horizontal and vertical limits allowed by their airworthiness approval. Purpose: The purpose of this document is to define the methods to be used as a function of the type of cargo in order not to exceed the maximum allowable center of gravity limits defined for each unit load device (ULD) configuration in AS36100 or@ for older unit types@ NAS 3610 standards@ so as to ensure: a. the ULD base and aircraft conveyance system maximum allowable area loads will not be exceeded@ and b. the ULD and aircraft cargo restraint system will not be overloaded in the event of in-flight accelerations. Field of Application: This document applies to all types of unit load devices for use on board civil transport aircraft@ airworthiness approved under TSO C90 in accordance with performance requirements and testing parameters of either AS36100 or NAS 3610 standards. This document shall also apply to any non airworthiness approved unit load devices@ such as ""non certified containers"" as defined in AS1677C@ of the same sizes@ the utilization of which is controlled by the aircraft type's Weight and Balance Manual provisions. This document applies to either air cargo containers or air cargo pallets to be restrained by the aircraft's cargo restraint system. It does not apply to non unitized cargo@ loaded in bulk or on a ""floating"" pallet not restrained in the aircraft's system (however@ in either case@ maximum allowable area load on the aircraft floor must be checked and complied with)."
