Where should the heaviest load be attached when using multiple cargo hooks on a CH-47?

The correct choice is to attach the heaviest load to the center cargo hook when using multiple cargo hooks on a CH-47. This approach is essential for maintaining stability and balance during flight. By securing the heaviest load at the center, it helps to ensure that the aircraft's center of gravity is kept as close to neutral as possible. This positioning reduces the risk of the helicopter experiencing undesired pitch and roll movements, which can occur if the load is unevenly distributed or excessively concentrated at one end.

In operations with multiple cargo hooks, the layout of the CH-47 is designed so that the center cargo hook is strategically positioned to handle the bulk of the load. This placement allows for better aerodynamic performance and enhances the overall safety of both the aircraft and the aircrew while in transit.

The other hooks have their specific purposes and are generally used for lighter loads or to balance out distribution when necessary, but they are not suited for carrying the heaviest load due to concerns over stability and control during flight. The distinction in cargo hook functionality plays a crucial role in mission planning and load management, which is critical for successful operations.
