What is the Sling Load Minimum Weight?

• A. 500 lbs
• B. 100 lbs
• C. 250 lbs
• D. 750 lbs

Answer: (A)

In sling-load planning, there is a practical lower bound on how light a payload can be when carried externally. The standard minimum weight is 500 pounds. This limit exists because very light loads tend to behave unstably in the air: the sling lines can go slack or swing excessively, gusts and rotor wash can cause large load movements, and the aircraft has to work harder to manage the load’s dynamics. A 500-pound mass provides enough tension and inertia to keep the load coordinated with the helicopter, making control more predictable and reducing risk to the aircraft and crew. If a payload weighs less than this, standard sling-load procedures aren’t used, and different methods or configurations would be required.
