What is the rear link count for the M149 Water Buffalo at 10k Apex?

• A. 70 for 10k Apex
• B. 75 for 10k Apex
• C. 60 for 10k Apex
• D. 90 for 10k Apex

Answer: (D)

In sling-load operations, how you rig the load changes with the operating conditions to keep the helicopter stable and the load under control. The rear end of the M149 Water Buffalo needs a higher number of rear links at a 10k apex to counteract the greater dynamic forces and potential sway that come with that height. Using more rear links distributes those forces more evenly and helps prevent the load from tilting or shifting during flight, which is crucial for safety and control.

So, at 10k apex, the rigging plan specifies a rear link count of 90 to maintain stability. The other numbers would be for lower apex conditions and would not provide enough control at the higher setting.
