The pilot chute bridle is connected between the pilot chute and a position on the main parachute canopy adjacent the crown area. The pilot chute bridle and six crown lines are equally spaced around the crwon area of the canopy. Each of the six crown lines includes a loop at their free ends. The thong-disc assembly includes six fabric thongs equally spaced together with the bridle around a circular disc. The crown line assembly includes seven panels with the pilot chute bridle line being secured along the junction of two panels and webbing member secured along other junction lines between panels. Pilot chute bridle attachment loops are connected to the webbing members and pass through a loop on the bridle. Thong-disc attachment loops are also secured to the webbing members and pass through the loops on the crown lines and then engage the thongs on the thong-disc assembly. (Author)
