ULD | What is Unit Load Device | Aviation | Concept | Types and Specifications

[0:00]Unit load devices ULD are used as containers for baggage and cargo. They are carried in the holds of suitably dimensioned and equipped aircraft and are secured so that they cannot move within the hold in flight. ULDs come in two forms: containers and pallets, also referred to as cargo pallets or PMC pallets. Each ULD has its own packing list or manifest so that its contents can be tracked. Each aircraft unit load device is identified by its ULD code. This code is a unique combination of letters and numbers, starting with a three-letter prefix that identifies the type of ULD. This prefix is followed by a unique four or five-digit serial number to distinguish it from others of the same type. The last two or three characters designate the owner of the ULD, for example, the airline. Many different parties handle ULDs as they pass between airlines and airports around the world, so a system was needed to identify easily and quickly each ULD. Therefore, the International Air Transport Association, IATA, introduced a global standard system of identification. Accordingly, each ULD is assigned a unique ULD code, which is clearly visible on the relevant unit. By standardizing the system, all manufacturers, cargo handlers and airlines can now identify the ULD's classification and the owner at a glance. The first three letters of a ULD code are perhaps the most important. They are used to identify the type, size and shape of the ULD. This information is vital in determining not only the type of cargo it can contain but also the aircraft it is compatible with. To summarize the three-letter prefixes. The first letter represents the type of ULD. The second letter represents the base size of the ULD, and the third letter represents the containers contour or the pallets restraint system. There are various ULD container types. You can pause and view the contents of each type as per your convenience.
