    Cutting Dacron

    Even if you had hot knife, you wouldn't want to use it - it would leave a hard sharp edge on the line. Just cut with a very sharp blade, like a razor blade, x-acto, or other very sharp knife. If you will be finger-trapping the line, remember to cut the line at a sharp angle.

    Newbie Question - NVG's?

    A night jump involves experiencing the limitations encountered when jumping at night. NVGs would be counter productive with regard to that goal. I would hope that officiating organizations (USPA, for instance) would dis-allow NVGs on jumps that were meant to satisfy a night jump license requirement.

    Skyhook collins question

    What sort of test? The Collins cannot release the right riser. The Collins stuff only affects the left riser. If you were just pulling on RSL (pulling on the disconnected shackle?) then there is no expectation that the right side will release. It is the release of the right side by pulling the cutaway handle that usually accounts for the force pulling on the RSL, so the expectation is that the right riser has already released. So, how were you doing your test? And what had you expected to happen?
  5. Maybe it would be too much, but I wonder if it maybe should automatically be posted at the top of each incident THREAD, and not just at the top of the FORUM. I rather doubt that the families of jumpers who visit this site and read the incident threads do a whole lot of background gathering before they delve into the thread about their loved one. So, would it be impossible to prepend that post to the beginning of every new thread when it is created? (I suppose this post should maybe be in the "Suggestions" forum, but I think I'd like to see it read more widely. Thanks!) -paul

    Slider doesn't stay collapsed

    Did you pull the cord(s) past the locking tab(s)? There are tabs sewn into the cords that form sort of barbs such that when you pull the barb all the way out of the slider channel, it won't go back in without some effort.
  7. Slower? Not necessarily. The adage in skydiving is "Slow is smooth - smooth is fast". TSO is TSO. Off the top of my head, the limits are something like 300' and 3 seconds. (Please verify. There is some Svedka effect here. But, I mentioned it, so I am probably not really dramatically impaired.) Openings can be brutal if they open all at once in the last half second. A smoother opening that starts at time 0 can be as quick as any opening in the past, and yet less brutal on your body. The Optimum had to meet TSO requirements. (We are told that this is the reason that the bigger Optimum reserves took longer to come to market.) (Now, to be clear and honest, some of this will depend on your rig. USPA tells us that there have been cases where the suspicion is that rigs were too tight, and reserves did not open in time. That's not the fault of the reserve, is it? We have a SYSTEM that must work properly for the limits to be met.) But the PD Optimum still had to meet the TSO limits.

    Judging by the experience of a friend who has owned a Silhouette for many years, no, the non-zp bottom skin (ribs too) will not decrease the lifetime of the canopy.

    Altitrack 18000f and 12000f the same?

    I think you might misunderstand the different models. Check here http://www.l-and-b.dk/altitrack.html The models are symmetrical or asymmetrical scales, with markings in feet or meters.
  10. Regarding the 10,000 dollar fee for the rescue, does any reader out there know if the USPA third party liability insurance will cover this?

    Links, French Links or Slinks...?

    Perhaps because a soft link, properly closed, cannot, short of catastrophic failure, open. I have seen french links in this and other locations that were loose or had actually opened. But, in general, I agree with your question - neither seems definitively better to me.
  12. Why choose ZPX if you don't need it to make the canopy fit in the first place?

    Argus SB?

    Are you talking about the recent announcement distributed by USPA? If so - I've had a couple of emails with Aviacom, and they say that the cutter recall does not apply anywhere other than France. There seemed to be some surprise to hear that USPA had published the bulletin. I don't know quite how I feel about that, but Aviacom's not going to replace my cutter or the cutters of my customers here in the USA. At least, not at this point. Anyway, it seems to be Aviacom's position that there is nothing wrong with the cutters, but that the French have required replacement nonetheless. (Don't get mad at me. I'm just the messenger.)

    Cutaway Landing Procedure?

    You mention "catch a cutaway main". If you really mean "catch", as in snag in the air before reaching the ground, I urge you not to do it. More than a few have found that such an air-caught main can do some horrible things, like partially inflate, at just the wrong moment. Regarding the idea that an opening after a cutaway would be around 1500 feet, well, sometimes yes and sometimes no. For example, if you are flying a long sniveling high performance canopy, for instance, you might open higher than the minimum your license allows. If you have a violent spinner, and you decide to delay the cutaway, you might find yourself unable to cutaway at all, as the G forces can build quite quickly. So the advice in such a situation is to chop before you lose the chance to. Actually, this isn't just limited to high perf canopies. If your main is treating you badly, and things could get worse, get rid of it while you can, and sort the rest out later. Sure, try to see where the main is going if you can. But don't put a whole lot of priority on it. I wouldn't suggest that you follow your main to an off-dz landing unless you are quite familiar with your reserve and are comfortable with landing it under less than ideal conditions. If you are injured landing your reserve off the dz, you are further from help, and maybe nobody even saw it well enough to know you need help. At my home dz there are usually folks watching who will notice a cutaway and do their best to figure out where it lands. Some will likely go to fetch the canopy before you land, because they are really nice folks and want to help as much as possible. After a cutaway, your first priority should be to get to as safe a landing area as you can, and finish the jump with the least possible injury. Worrying too much about the main could distract you from this, and the result could cost you a whole lot more than a lost main would.
