What kind of loads should be avoided in sling load operations?

Avoiding unevenly distributed loads in sling load operations is essential because these types of loads can lead to instability during transport. When the weight is not evenly balanced, the load can shift unexpectedly, which may result in loss of control, increased risk of swinging, or even accidents during lift-off and landing. Properly balanced loads ensure that the helicopter can maintain stability and control throughout the sling load operation, enhancing safety for both the aircraft and personnel on the ground.

In contrast, weight-restricted loads, non-cargo items, and flat, balanced loads are situations that may have specific considerations but do not inherently pose the same level of risk as unevenly distributed loads. Weight-restricted loads must simply not exceed the designated weight limit for the aircraft, while non-cargo items may be subject to different protocols for handling. Flat, balanced loads are, in fact, what should typically be aimed for in sling load operations, as they promote safe and effective transport.
