Air Cargo Unit Load Devices – Center of Gravity Control Methods
|Publication Date:||1 November 2012|
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.
The purpose of this document is to define the methods to be used as 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.
