External Dimensions

The extreme outside measurements, including any handles or other protrusions of a ULD.

External Volume, ULD

The amount of space a ULD occupies in an aircraft, calculated using the extreme external dimensions of the unit.

High Capacity Aircraft

Seat Track

A standardised device designed to accept tie-down fittings. It is typically a continuous track capable of accepting tie-down fittings at any of the regularly spaced intervals provided. May also be referred to as a cargo track

ShellThe superstructure of any container or igloo

Tare Weight

Weight of the empty ULD. It includes all liners and / or fittings.

Thermal ULD

A ULD built with insulating walls, doors, floor, and roof which retard the rate of heat transmission between the inside and the outside of the ULD.

Tie-down Fitting

An attachment device designed to transfer forces between a load-bearing device such as a net, strap, rope, or bar, and a seat track.

Tie-down Strap

A strap which secures a load to the ULD or the aircraft restraint system.

Unit Load Device (ULD)

Any type of container, container with integral pallet, aircraft container, or aircraft pallet.

Weight & Balance Manual

Specific document for each aircraft that controls the type and number of ULDs that can be loaded, their allowable weight and information on alternate loading arrange ments such as throw-over straps and nets, broken restraint hardware, and loads that exceed normal allowances.
