Unit Load Devices (ULDs) are the air freight version of shipping containers. While their size is standard, the methods of ULD handling, storage and transport and not. As a result, ULDs are also the leading cause of aircraft damage on the ground.

To help reduce the $400M annual repair bill and knock-on effects of cancellations and delays, we’ve put together a set of handling regulations specifically for ULDs. The publication covers the technical and operational responsibilities and various airline requirements as well as design and manufacturing specifications.
