Which of the following is a correct statement about UH-1N/Y compatibility with POAs?

The correct statement about UH-1N/Y compatibility with POAs is that only polyester slings can be used. This is due to the properties of polyester, which make it more suitable for aviation use. Polyester has a higher resistance to UV degradation and abrasion compared to nylon, which ensures greater durability and safety in helicopter sling loads. Additionally, polyester does not stretch as much as nylon under load, providing more precise control and stability during transport.

While other materials are often used in different situations or equipment, the safety requirements and specific operational conditions for the UH-1N/Y necessitate the use of polyester slings to ensure optimal performance and minimize risk during aerial operations. Hence, this specification helps maintain safety standards and operational effectiveness in aviation environments.
