What markings must be included on center of balance markings?

The correct response encompasses the essential elements that must be included in center of balance markings for air transportation. Specifically, it entails the gross weight of the item being transported, the center of balance (C.B.) marking itself, an arrow indicating the forward freight edge (FFE), the inch marking to denote the measurement, and the designation of F.F.E. This comprehensive set of markings ensures that personnel can accurately determine the weight distribution and handling of the load, which is vital for maintaining aircraft balance and safety during flight operations.

Each element serves a specific purpose: the gross weight indicates the total weight of the cargo; the C.B. marking identifies the center point above which weight is evenly distributed; the arrow directing to the FFE helps in understanding the orientation for loading or unloading; the inch marking provides a reference for dimensions; and the designation for F.F.E. highlights the leading edge of the freight for loading sequence purposes. Collectively, these markings facilitate effective operational practices in air freight management.
