Unit Load Device (ULD)

Last updated: January 29, 2026

A Unit Load Device (ULD) is a standardized container or pallet used in air cargo to group freight for efficient loading into aircraft. ULDs allow carriers to secure, organize, and transport goods safely during flight operations. Each ULD has a unique identification number and is designed to fit precisely into aircraft holds, maximizing space and maintaining cargo integrity. In ERP systems, ULD tracking supports inventory control, load planning, and return coordination.

How the Unit Load Device Works in Logistics?

When cargo is prepared for air shipment, it is packed into a ULD, either a container (for enclosed goods) or a pallet with a net. The ERP logs the ULD number, contents, weight, destination, and flight schedule. As the ULD moves through the logistics cycle, its status is updated in real time: loaded, departed, arrived, or returned. This data supports air cargo documentation, billing, and ground handling coordination, making ULD management a critical component in aviation logistics.

Application of the Unit Load Device in Logistics ERP

Flight-Specific Load Management

Each ULD is assigned to a flight or route and matched with cargo destined for the same location. This simplifies loading plans and reduces sorting errors.

ULD Identification and Tagging

The ERP stores the unique ULD ID along with its type, capacity, owner (airline or agent), and assigned cargo, enabling visibility throughout its use.

Weight and Balance Planning

Accurate ULD weights are fed into aircraft load planning tools to ensure flight safety and fuel efficiency, which is critical in air logistics.

Return and Reuse Tracking

ULDs must be returned to their owners after use. ERP systems monitor usage cycles, empty returns, and maintenance needs to avoid losses and delays.

Damage and Maintenance Records

ERP-linked maintenance logs capture wear, repairs, or damage for each ULD, ensuring compliance with air transport standards and equipment longevity.

Conclusion

Unit Load Devices are essential to the efficiency, safety, and organization of air cargo operations. By integrating ULD tracking into ERP systems, logistics teams gain control over load planning, inventory, and equipment usage. With visibility into each ULD’s journey and condition, companies can reduce costs, ensure compliance, and deliver cargo with precision.
