What is a common indicator of a rigging issue in parachutes?

Uneven lines are a significant indicator of potential rigging issues in parachutes because they directly affect the parachute's ability to open and perform properly during descent. When the lines are uneven, it can lead to a variety of problems such as accurate canopy inflation, stability in flight, and overall safety during descent. Uneven tension can result in a skewed canopy that may not inflate correctly, leading to unpredictable behavior, which could compromise the safety of the jumper.

In contrast, pilled fabric may indicate wear but does not necessarily point to immediate rigging safety. Unfolded toggles, while important for operation, are often related to the pre-jump preparation phase rather than the rigging of the parachute itself. Wrinkled deployment bags may also suggest some maintenance issues but do not usually signify critical rigging issues. Therefore, recognizing uneven lines is crucial for ensuring safe and effective parachute performance.
