What is the minimum safe weight of a sling load to fly?

• A. 500 LBS
• B. 1000 LBS
• C. 250 LBS
• D. 750 LBS

Answer: (A)

In sling load operations, the load must be heavy enough to fly safely. A sling load that's too light can behave like a pendulum, swinging with gusts and rotor wash, making it hard for the pilot to control the helicopter during hover, transport, and set-down. The minimum safe weight is the smallest load that still provides enough inertia and damping to keep the sling stable while staying within the aircraft’s flight limits. Five hundred pounds is the smallest load that meets that safety margin. It gives the load enough mass to dampen oscillations and maintain controllability, while still being within the helicopter’s lift and handling capabilities. Heavier loads, like seven hundred fifty or one thousand pounds, are safe but not the minimum. A quarter-ton (two hundred fifty pounds) is too light to meet the stability and handling requirements for sling loads.
