本文件定义了航空货运单元装载装置（ULD）底座上的载荷分布的行业一致模型，以应用最大允许重心（C.G.）偏心率。 其目的是建立一个通用的参考负荷分配算法，用于: a） 可比较且可重复的ULD测试方法，或等效的数值模拟； b） 飞机结构和货物系统设计假设，与现有机身惯例一致；和 c） 操作员单元负载设备使用规则和货物集结培训计划的定义。 本标准适用于民用运输机上使用的所有类型的单元负载装置，以及根据ISO 21100或ISO 8097（如适用）的性能要求和测试参数批准的适航性。 它还适用于ISO 4118中定义的非适航批准（非认证）集装箱，其使用受飞机型号重量和平衡手册及其他机身制造商文件的规定控制。

This document defines the industry agreed model for load distribution on air cargo unit load devices (ULD) bases to apply the maximum allowable centre of gravity (C.G.) eccentricity. Its purpose is to establish a common reference load distribution algorithm for: a) comparable and repeatable ULD testing methods, or equivalent numeric simulations; b) aircraft structure and cargo systems design assumptions, consistent with existing airframers practices; and c) definition of operators unit load devices utilization rules and cargo build-up training programs. It applies to all types of unit load devices intended for use on board civil transport aircraft and airworthiness approved in accordance with the performance requirements and testing parameters of either ISO 21100 or, as applicable, ISO 8097. It also applies to non-airworthiness approved (non-certified) containers as defined in ISO 4118, the utilisation of which is controlled by the provisions of the aircraft type's Weight and Balance Manual and other airframe manufacturer's documents.
