In some aircraft the two types must be mixed as some compartments take only specific ULDs. On passenger aircraft, a record of which checked bags are stowed in which ULD is normally kept regularions that if it is necessary to retrieve a particular item prior to flight, it should be known which ULD it has been loaded in.

Ground Operations Content source: Archived from the original on On cargo aircraft, ULDs are often used in combination with netted pallets. Main deck ULDs use curves for the contoured shape to truly maximize cargo volume.

Position 1 letter identifies ULD category certification, ULD type, thermal units ; [46] Position 2 reguoations identifies standard base dimensions: The primary purpose of ULD is to improve flight safety compared to bulk loading of holds. Retrieved from ” https: Unit Load Devices ULD are used as containers for baggage and cargo carried in the holds of suitably dimensioned and equipped aircraft and are secured so that they cannot move within iatta hold in flight.

These loads are extremely high, in order to prove that the design is capable of restraining the contents of the iaha ULD under extreme flight conditions, for example:.

PMCs can only be loaded in cargo compartments with large doors designed to accept them small door compartments are container only.

While airlines may choose to make their own definitions as to exactly what types of ULD may or may not be loaded on their aircraft, it should be remembered that many ULD are transferred between aircraft and even other airlines before reaching their destination.

Lists What are lists? It is the responsibility of the ULD designer to create clear instructions regarding the use of the ULD, and to include them in the operations manual.


In order to obtain approval or certification from the authorities, the designer must submit calculations and test results to show that the ULD is able to withstand the loads required while being restrained in the manner laid out in the TSO standards. Loading of pallets is similar to loading containers; particular attention should be given to the cargo net being used to secure the load to the pallet.

Since this leads to fewer units to load, it saves ground crews time and effort and helps prevent delayed flights.

An LD8 takes the space of two LD2s. Outdoors racking should be equipped to prevent containers blowing away in windy conditions.

Each ULD has its regulatilns packing list or manifest so that its contents can be tracked. Additionally, airlines should make operations manual instructions on the correct use of the ULD available to all parties involved in loading and unloading the aircraft. By necessity they are made as light as possible, however they may be subjected to extremely severe handling conditions.

ULD containers, also known as cans and pods, are closed containers made of aluminum or combination of aluminum frame and Lexan wallswhich, depending on the nature of the goods to be transported, may have built-in refrigeration units.

There are several common types of contoured main deck ULDs, that are contoured curved to fit in the plane’s body to provide as much cargo volume as possible.

Non certified ULD may be used in an aircraft having a hold structure which is deemed capable of withstanding the forces from the contents during extreme flight conditions. This greatly simplifies transportation of cargo containers at slight cost of cargo volume. Set up My libraries How do I set up “My libraries”?

These standards also state clearly that unless a Iaya is specifically designed to be handled by a forklift it should not be so handled; otherwise damage may result.


Poor handling may well result in a ULD, which was perfectly serviceable when loading commenced arriving at the aircraft door in an unserviceable state, resulting in off loads, delaysreloads and other inconveniences.

The use of cargo straps to secure any piece of cargo in lieu of a net requires great care and should only be done in accordance with the carriers specified procedures. This single location in All: If removable they should be stored in regulationz dry location.


ULDs come in two forms: The uses the smaller LD2s and LD8s because of its narrower fuselage. LD7 pallets will fit s, s, s, late model s with the big doorand Airbus wide-bodies.

These online bookshops told us they have this item: Containers are typically lightweight structures comprising a structure of aluminium extrusions, a relatively thick 2. Wikimedia Commons has media related to Unit load devices. Be the first to add this to a list. These may be used to connect a tie down strap terminated only with a hook into the pallet edge rail. Upper deck ULDs are just like lower deck ULDs that are either the full width of the plane with two corners of the profile removed lower deck LD6 loweror that container is cut in half, down the center line of the plane, lower deck LD3 and upper deck AAX.

Many air cargo companies use main deck ULDs that have both features called dual-profile, so that on smaller planes such as the Boeingthey are stored widthwise and have two corners contoured, and on the bigger Boeingthey can be rotated 90 degrees and shipped in parallel like LD3s, so that only one corner is contoured when being used like an LD3. In order to set up a list of libraries that you have access to, you must first login or sign up.

A ULD not loaded in compliance with these instructions may very well not be able to carry out its defined purpose of providing restraint to the contents in flight, and should not be allowed on board the aircraft. Empty containers should only be stacked where there exists proper training and controls and where the containers are designed to be lifted by forklift.

Retrieved from ” https: Civil aviation Shipping containers Air freight. In other projects Wikimedia Commons. Policies vary from airline to airline as to whether such transfers are allowed. With the exception of a ULD which is approved for forklift handling, they should never be left on the ground even if empty.
