How is the proper drag surface achieved during rigging?

The proper drag surface is achieved during rigging by applying a proper link count. The link count refers to the number of suspension links used in the rigging process, which directly affects the drag surface area that can be manipulated to achieve stability and control during descent. An appropriate link count ensures that the parachute's canopy opens correctly and that the load being transported can descend safely and predictably.

When the link count is set correctly, it helps to distribute the load evenly across the parachute, allowing for the desired aerodynamic characteristics to be realized. This setup is crucial because improper link counts can lead to malfunctions or instability during descent, potentially compromising the safety of the operation.

Other methods such as weight distribution, adjusting slack, or using additional equipment may impact the overall performance of the rigging but are secondary to ensuring that the link count is appropriate for achieving the intended drag surface.
