What are the two primary types of lines involved in a parachute system?

• A. Suspension lines that connect canopy to risers and bridles used during deployment.
• B. Reinforcement lines and seam lines.
• C. Riser straps and tethers.
• D. Pilot lines and anchor lines.

Answer: (A)

The main idea is that a parachute system uses two broad kinds of lines that serve different jobs: suspension lines and deployment lines. Suspension lines run from the canopy to the risers and carry the load when the parachute is deployed, helping to keep the canopy properly inflated and shaped during flight. Deployment lines, or bridles used during deployment, are shorter lines that help pull the canopy free from the pack and guide a smooth opening, starting the inflation process as soon as the canopy begins to deploy. Understanding these roles helps: suspension lines are about supporting and shaping the canopy in flight, while deployment bridles are about reliably initiating opening and starting inflation. Other options refer to fabric features (reinforcement or seam lines) or hardware and control elements (riser straps, tethers, pilot lines, anchor lines) that aren’t describing the two primary line types involved in the basic parachute system.
