    "The user can 'disengage' the RSL lanyard by disconnecting the snap shackle, if in an emergency situation or to avoid a possible emergency situation ONLY." (The italics/underlines are theirs.)



    So now jumpers just need to declare that they are avoiding the possible emergency situation of 'unstable reserve deployment', and they can disconnect the RSL at will. Right? ;)

  6. Judging from the marks left on the snow you were not gliding very well. This suggests that:

    1) the Blade glides like brick
    2) It doesn't matter as the fallrate seems to be amazingly low.

    That might make flocking with other suits slightly difficult, though.:P

  7. There is a way of misrouting your bridle with a pull-out system(see attachment) that you can only do when packing left-right. This could cause a hard or impossible pull. A similar misrouting can theoretically cause a pc-in-tow on a throw-out system, but I think the chances of that happening are fairly slim.

    Also right-left seems to keep the bridle tighter(more secure) under the right-hand flap, which may be a good thing on rigs that don't pack very tight.

  14. I had a minor issue with the carabiners. I was going up in a C206 to try the suit, and the legstrap of the person sitting in front of me got caught in the carabiner. No big deal, I noticed it when he was getting up before jump run and un-clipped the carabiner. It took a while but there was no damage to the strap or anything.

    The high cutaway forces associated with line twists have nothing to do with the rings.



    Sure they do. The smaller the rings, the larger the forces. Of course, compared to the difference hard housings make the size and type of the rings may not make much difference.

    Here is a chart on 3-ring loads and pull forces that I compiled from information available on the RWS and Aerodyne websites.

    Is bag lock possible in a situation when the pull force of a pilot chute excess the force need to break a rubber band? Were there any malfunctions which could be clearly traced to a modern rubber band used on sport systems, which did not broke?



    I chopped one. I double wrapped a locking stow even though it had been made clear to me that doing that would be a bad idea. The rubber band did break - eventually. By that time the bag had been spinning at the end of the lines for a second or two and the canopy that came out was definitely not "square, symmetrical and steerable". I don't double wrap locking stows, but I will double wrap non-locking stows if small rubbler bands are not available.

  17. Some people call it "line dump" which is actually a related phenomenon but not quite the same.

    The way I see it:
    Line dump: All lines deploy simultaneously
    Bag strip: D-bag opens and canopy starts to deploy before line stretch

  18. It is made by Performance Variable in Germany. It's a very straightforward 9-cell zp canopy with a rectangular planform. I've jumped it once or twice and it opened hard, but that of course may have been bad packing.

  20. It should've been a "multiple answers allowed" poll. I would've picked the last three. :S Yes, it's there just to "Cover Your Ass". Yes, I don't like to think about it much. Death continues to suck. Yes, I know bad things can and do happen to people I know.

    It seems to me that there are always skydivers who do think that jumping is safe. They are generally the people whose DZ hasn't had a serious incident for as long as they've been jumping. When bad things happen to people you know it really makes the possible consequences much more real.

    Zenister: Here are the Instructions if you need to brush up a bit...:P

  23. Getting the riser covers to stay closed on older Atoms is tricky even when the reserve is the right size.

    Bulk distribution in the reserve packjob is critical; the "ears" of the molar bag must be left practically empty. If the top part of the finished packjob(the molar "ears") doesn't feel very soft compared to the rest of the packjob, the flaps will have trouble staying closed. Also if your risers have anything else but the original Atom toggle system(which has very low bulk) that will contribute to the problem.

    Have another rigger take a look at your rig, preferrably one that has lots of experience with Atoms. With a reserve that's too big, you may be out of luck in any case.

  24. The Wolmari-pack has been used for years and I've never heard of any ill effects. I now always pack tandems using that method. With my sports rig I sometimes use the Wolmari, and sometimes the traditional method, depending on my mood.
