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

• A. 10 for 25k Apex
• B. 60 for 25k Apex
• C. 15 for 25k Apex
• D. 90 for 25k Apex

Answer: (A)

In sling-load planning, the rear link count is the number of chain links used in the rear leg of the sling to secure the load. This count is chosen to give the right sling angles and balance for a given aircraft and load configuration, keeping the load stable and ensuring proper clearance.

For the M1097 HMMWV with a 25k Apex setting, ten links in the rear sling is the prescribed arrangement. This length helps maintain correct balance, keeps the rear of the vehicle clear of the helicopter and ground clearance issues, and distributes tension appropriately across the load points.

Using a different number would change the sling angles and the load’s center of gravity, which could create clearance or stability problems, so those other values are not used for this configuration.
