Managing ULD Records

The ULD records contain specific handling information, including status and location of ULDs. ULD records are managed in the ULD Control screen found in Master Data > ULD Control.

Specific information regarding containers, pallets, and other ULD types are stored as ULD Type records. These record types can be created, edited, and viewed in Master Data > Others > ULD Types depending on the access rights of the currently logged on user.

ULD Type

Each Aircraft Unit Load Device (ULD) 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 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.

The three-letter prefix works as follows:
  • The first letter represents the type of ULD
  • The second letter represents the base size of the ULD
  • The third letter represents the container’s contour or the pallet’s restraint system
