Link rear for M1101?

• A. 3
• B. 75
• C. 20
• D. 90

Answer: (A)

The idea being tested is how rear rigging is sized for sling-load operations with the M1101. For this vehicle, the rear link is set to three chain links. That short, fixed length places the rear attachment at the correct position relative to the vehicle’s front attachment and the helicopter’s sling geometry. With three links, the load’s center of gravity remains properly balanced between the front and rear legs, aiding stability during lift and reducing the risk of excessive tilt or contact with the airframe and rotor wash.

Using a much larger rear link length would shift the load geometry, making the rear sit too far back and potentially destabilizing the lift. Values like 75, 20, or 90 are not appropriate lengths for this purpose, and they don’t align with the standard rigging configuration for the M1101.
