During sling load flight, which direction does the front of the M149A2 Water Trailer face?

• A. Front
• B. Rear
• C. Left
• D. Right

Answer: (B)

In sling load flight, how the load is oriented relative to the helicopter is all about stability and control. The M149A2 Water Trailer is intended to be carried with its front end toward the helicopter’s rear. This arrangement places the load’s weight in relation to the sling points so the center of gravity stays aligned with the lift and the helicopter’s longitudinal axis, which helps dampen pendulum motion and keeps the load following the aircraft smoothly rather than swinging side to side. If the front faced the front, the center of gravity would be forward of the sling points, increasing forward pitching and making the load harder to control. If it faced left or right, the lift would become asymmetric, causing more yaw or roll. So orienting the trailer with the front toward the rear provides the most stable, predictable behavior during flight.
