What is a Unit Load Device ?
A unit load device, or ULD, is a pallet or container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows a large quantity of cargo to be bundled into a single unit. Since this leads to fewer units to load, it saves ground crews time and effort and helps prevent delayed flights. Each ULD has its own packing list (or manifest) so that its contents can be tracked.


Pallets and Containers
In aircrafts, cargo is loaded and carried in various pallets and conatiners known as Unit Load Devices ( ULD ) .
