What is the LBZ for the 10,000 Lb cargo net?

• A. 5 ft x 5 ft
• B. 6 ft x 6 ft
• C. 7 ft x 7 ft
• D. 4 ft x 4 ft

Answer: (B)

LBZ is the safe footprint the helicopter must place the load within during sling-load operations. Heavier loads require a larger area to accommodate the load’s possible sway, the sling geometry, and to keep everything clear of rotor wash and obstacles. For a 10,000-pound cargo net, the standard footprint is six feet by six feet, which gives enough clearance for the net spread and rigging while keeping the load inside the rotor-swept area. A smaller footprint wouldn’t provide enough margin for sway or rigging, increasing the risk of ground contact or interference with the aircraft. A larger footprint isn’t necessary for this load class and could complicate placement.
