When designing an Aircraft Unit Load Device (ULD), careful thought is given to making the most of the aircraft’s cargo space. Unfortunately, aircraft holds come in many shapes and sizes, which means that ULDs also have to come in many shapes and sizes.
Since ULDs are often transferred between different types of aircraft, this gives rise to three types of fit: optimal fit, non-optimal fit and no fit:
Clearly, a ULD that fits the contour of the hold maximises the aircraft’s cargo space. In addition, a ULD can be an optimal fit for one or more than one type of aircraft. That doesn’t mean this ULD can’t be used in another type of aircraft if it’s not an optimal fit. In fact, it may be compatible with several different aircraft. It simply won’t be making the most of every hold’s space.
Optimal fit, non-optimal fit and a combination of an optimal and non-optimal fitting container.
One example of an optimal fit and two examples of a non-optimal fit.
The contour you select depends on a few factors:
To help you select the best contour for you, VRR has developed an ULD – Aircraft compatibility tool.
