What are loads that have been denied sling load certification called?

Loads that have been denied sling load certification are referred to as prohibited sling loads. This classification indicates that these loads do not meet the necessary safety and operational standards established for safe air transportation by sling. The prohibition typically arises due to specific characteristics of the load, such as size, shape, or weight distribution, which can pose a risk during flight.

Understanding the term "prohibited sling loads" is crucial for personnel involved in air transport operations to ensure they can identify which loads may not be transported via helicopter sling, thereby maintaining safety and operational effectiveness. Recognizing these prohibited loads helps prevent accidents and ensures compliance with aviation regulations.

The other terms, such as unique, accepted, and standard sling loads, describe loads that either meet certification requirements, differ from typical requirements but are still accepted, or are regular loads commonly used. However, they do not reflect the critical safety implications associated with loads that have been denied certification.
