How many main lift web adjustment straps are included in the harness assembly?

The correct answer is based on the standard configuration of parachute harness assemblies, which typically include two main lift web adjustment straps. These straps are designed to allow the jumper to adjust the fit of the harness for optimal comfort and safety while maintaining proper alignment and support during the jump. Having two adjustment straps helps ensure that the harness can securely fit a wide range of body types and sizes, crucial for effective parachute deployment and control during descent.

This configuration is essential for ensuring that the harness functions correctly and supports the jumper effectively in various scenarios. The presence of only one strap would likely compromise adjustability, while more than two could complicate the design and increase the risk of improper fitting and adjustment. Therefore, two main lift web adjustment straps are the industry standard in harness assemblies used in jump operations.
