LD3

LD3 is a standard unit load device (ULD) container used to transport freight in the lower holds of aircraft. It is part of the LD family of containers defined by the International Air Transport Association (IATA) as part of the standardized ULD system. The LD3 is designed to be lightweight yet sturdy, suitable for use in the belly holds of both narrow- and wide-body aircraft. It is typically constructed from aluminum with reinforced panels and end doors, enabling secure access and efficient loading.

As a container, the LD3 is used to carry palletized freight and is compatible with pallet nets and securing straps. It is designed to fit within common lower-deck loading configurations, enabling interchangeability among carriers and airports that follow the IATA standard. Ground handling equipment such as forklifts and pallet tugs are used to load and unload LD3s, and they are designed to be stackable when empty.

The LD3 is part of the LD family, which also includes other sizes such as LD1, LD2, and LD7. These containers were developed to standardize air cargo handling, improve safety, and increase efficiency by enabling consistent dimensions, weights, and handling procedures across carriers and aircraft types. Variants and interchange among carriers have helped reduce cargo handling complexity in global air freight networks.
