What is a ULD?

ULD stands for Unit Load Device. It’s essentially a pallet or container used in the aviation industry to consolidate cargo for easier handling and transportation. ULDs come in various shapes and sizes to accommodate different types of cargo and aircraft. They’re designed to fit seamlessly into the cargo holds of airplanes, allowing for efficient loading, unloading, and transportation of goods.
