For the M1097 HMMWV at 25k Apex, what is the front link count?

• A. 60 for 25k Apex
• B. 30 for 25k Apex
• C. 50 for 25k Apex
• D. 75 for 25k Apex

Answer: (A)

In sling-load rigging, the front link count is about setting the length of the forward sling leg so the load sits balanced under the helicopter. The number of chain links you put in the front leg determines how far forward the load hangs and how the load’s center of gravity aligns with the aircraft’s centerline during the lift. For the M1097 HMMWV at a 25k Apex configuration, the diagram specifies 60 links for the front leg. This length helps achieve the correct lift angle and keeps the load stable as it rises.

Choosing fewer links would shorten the front leg, causing the front of the load to ride higher and risking nose-up instability. Using more links would lengthen the front leg too much, potentially sagging the front and altering sling tension beyond safe limits. So, 60 links is the setup that produces the proper balance and control for that specific configuration.
