What is typically required to secure cargo on a helicopter?

To effectively secure cargo on a helicopter, both netting and straps are typically required. Straps are used to tightly bind and hold the cargo in place, preventing it from shifting during transport due to the helicopter's, often turbulent, flight conditions. Netting serves as an additional layer of security by encompassing the cargo, providing further stability and containment. This combination ensures that the load remains secure and balanced, reducing the risk of accidents or cargo loss during flight.

Using only straps may not provide adequate support for larger or more irregularly shaped loads, as they alone could allow movement and shifting under the forces experienced in flight. Magnetic clamps, while useful in some applications, are generally not appropriate for securing standard cargo on helicopters. Therefore, the combination of netting and straps is the safest and most effective method for cargo security in aviation contexts.
