When delivering multiple loads with a CH-47, where does the heaviest load go if it is the last to be delivered?

When delivering multiple loads with a CH-47, the heaviest load should be attached to the center cargo hook if it is the last to be delivered. This practice is based on the principles of load distribution and stability in flight. The center cargo hook is designed to provide the best balance for the helicopter, facilitating a more stable flight during transport, especially when multiple loads are involved.

By placing the heaviest load in the center, it helps to minimize the pitch and roll tendencies that can occur when heavier loads are distributed unevenly. The CH-47 is designed to manage loads effectively, but ensuring the heaviest portion is centered increases safety and reliability during the sling load operation. This configuration reduces the risk of lifting dynamics that can lead to decreased control or potential accidents.

The choice of the center cargo hook over the forward or aft hooks also aligns with the aircraft's capabilities, as it can more easily accommodate the weight while maintaining the overall center of gravity. Other options, such as the forward or aft hooks, could lead to an imbalance, compromising the aircraft's performance during the sling load operation.
