本SAE航空航天标准（AS）的范围应包括定义和确定主甲板和下层飞机货舱“内部体积”的方法。为了提供最大的ULD外部轮廓和定义ULD内部体积的方法，还应说明隔间外壳和单元装载装置（ULD）之间的最小所需间隙。

The scope of this SAE Aerospace Standard (AS) shall cover the methodology of defining and determining the "internal volumes" of both the main deck and lower deck aircraft cargo compartments. The minimum required clearance between the compartment envelope and the unit load devices (ULDs) shall also be stated in order to provide the maximum ULD external contour and the methodology to define the ULD internal volumes.
