Newbie 0 #1 May 4, 2004 my pc kill line was changed about 50 jumps back, this was on a pc that was brand new with only approx 50 jumps on it at the time - my rigger was surprised it had shrunk that quick after so few jumps, considering it was brand new from the factory. Now, by the time i have the bag sat in the container i have to tug the hackey a little to cock the pilot chute out an inch or so, as the kill line tends to pull on the PC a little (not kill it or anything near killing it, but enough so that the apex is near, or slightly level with the skirt.) I always check and make sure the kill line is straight from the base to the apex and pull the cocked pc through the air a few times, but it doesnt seem to catch as much air as it used to when i do that now. What im wondering is is this normal? That after 50 jumps you should have to keep getting the kill line changed out? I know it shrinks over time due to friction but over 50 jumps - that seems a pretty small amount to me. If this isn't normal, what could be causing the kill line to shrink so quick?

diablopilot 2 #2 May 4, 2004 On a properly calibrated kill line p/c the apex suport tapes will be shorter than the kill line when cocked. You can check this by holding the P/C by the bridle, pulling down on the hacky/handle, and looking through the mesh at the tapes. If, when your rigger changed the kill line he made it so short that the kill line was taught, but not the tapes, then it is starting life out of trim. On my newly manufacturerd kill line P/C the slack in the kill line is between 1" and 1 1/4" when examined as stated above. I've found I can get 400 to 500 jumps out of a kill line ZP P/C. YMMV.---------------------------------------------- You're not as good as you think you are. Seriously. Quote Share this post Link to post Share on other sites

JP, I think if you use this method, you won't be able to see the slack in the line, as the tapes will only let you pull the kill line as far as the tapes themselves. My usual practice during packing is to pull the kill line itself--until taut--from where it exits the bridle and enters the PC. Then, I let it fall back into the PC and smooth the bridle out. Look inside the pc and you will see exactly how much slack there is in the kill line. mike Girls only want boyfriends who have great skills--You know, like nunchuk skills, bow-hunting skills, computer-hacking skills.

Never had any trouble with this method, but as you say your tecnique works too.---------------------------------------------- You're not as good as you think you are. Seriously.

Technically, you will be able to see the slack in the kill line using this method, you'll just have to look inside the D-bag for it. I personally cock the PC with the hackey and look at the tapes. If the tapes are taught, I'm happy - I could have zero slack in the kill line for all I know, but since I do this check almost every jump, that doesn't scare me. -=-=-=-=- Pull.

masher 1 #6 May 5, 2004 That's what I do. I check that the tape insode the PC is tight.-- Arching is overrated - Marlies Quote Share this post Link to post Share on other sites
