Why can't a load be less than 6,000 lbs if carried by a CH-53E/K?

The correct answer centers on the characteristics and operational limitations of the CH-53E/K when handling sling loads. In this context, the system is designed to lift loads that meet certain minimum weight requirements to ensure stability and safety during flight. If the load is less than 6,000 pounds, it can result in difficulties with proper handling and stability.

This minimum weight requirement is crucial because lighter loads do not provide the necessary downward force on the hooks and associated hardware, which can lead to complications during transport. These could include excessive sway or movement of the load, potentially leading to a situation where the load cannot be jettisoned safely if needed, as it may not have the necessary tension or connection to maintain security.

For successful airlifting, maintaining a minimum load weight is vital to ensure the integrity of the cargo handling system and overall flight safety.
