mr2mk1g 10 #1 October 5, 2004 Hold a PC “upside down” by its bridle. Should the apex sit level with the point where the ZP and mesh meet or should it be above or below that line? For the avoidance of doubt, this is a collapsible PC and the kill line has plenty of slack – the determining factor in the lie of the apex is the tape within the PC. cheers Quote Share this post Link to post Share on other sites

mark 107 #3 October 5, 2004 From Poynter's, where he talks about pulling down the apex of a round main parachute, but applicable to pilot chutes as well: "The adding of a center line to pull down the [apex] will increase the projected diameter... Ultimate canopy spreading is achieved when the center line is the same length as the suspension lines. Drag may be increased by about 18%." For "the suspension lines," substitute "the mesh" or "the tape on the mesh." to describe what's going on with a typical non-spring pilot chute. Being off by a half inch (1 cm) or so either way isn't going to change the drag very much, and given the number of folks I've seen happily jumping pilot chutes with kill lines a couple inches short, I'd say an inch either way might be enough for a call to the manufacturer but not a cause for great alarm.
