    ***Telesis with an SOS?

    http://www.parachutesaustralia.com/s2/prod_telesis.php

    Not exactly the same thing but that was the first thing that came to mind...



    I hate hate hate hate hate hate hate the fact that those exist and are still being manufactured. There is absolutely no reason to be training people on gear that is substantially dissimilar to what they will actually use unless they are at a staticline DZ.

    Those exist for various reasons besides staticline dzs.

    Hi g2g,

    Do you have an idea what it was?



    Two rigs come to mind.

    The early Centaurus rigs built by Centaurus Corp. had them that way. I do not know if the NAA Centaurus rigs have them that way.

    The EOS by Para-Flite had/has them that way.

    I just downloaded the EOS manual and it was the rig I was thinking of. Thanks Jerry!

    Over the years, we have experimented with a lot of different release systems and handles. The current handle configuration is the result of many deaths and more "close-calls."
    IOW The current handle configuration is "the least of the evils." Canopy release and reserve ripcord handles have not changed since the mid-1980s.
    During the early 1990s, the skydiving industry standardized on BOC main deployment.
    Now compare accident, incident and malfunction rates (see United States Parachute Association Annual Fatality Summaries) between the 1970s and the 1990s. You will find far fewer low-pull/low-pull deaths since 1990s.

    For example, a 3-Ring system requires a pull of less than 5 pounds to release. That is why 3-Ring handles still have "antiquated" Velcro, to increase the pull-force to the point that they rarely fall off accidentally.



    This is a little off topic but Rob i think you can answer it.

    I recall seeing a rig that had the cutaway and reserve handles above the chest strap. I wanna say it was a naro or a clone of a vector/talon.

    Do you have an idea what it was?

    Anyone have any experience jumping a Laser 250 at wingloadings between .7 and 1:1?

    Any comparison in construction and flight characteristics vs a Raven 3 would be particularly helpful.

    I am assembling a demo/flag rig and am trying to determine which would be a better option for the reserve. I already own both, am familiar with the Raven, but I noticed that the Laser is certified C23c Cat C 175kts vs the Ravens Cat B 150kts. So is it better/stronger?

    I could test jump them myself, but if anyone out there has experience and a strong opinion one way or the other to share it would save me some hassle....



    My mind is a little bit foggy on this, but i thought once a raven was hooked up as a main and jumped it would void it as being a reserve canopy? Or, it might be legal if you have some sort test rig in which you could pack it into the reserve container and have a belly back up. I would check the manual and or call precision.

    Poor equipment selection

    elaborate please?



    The container appears to be overstuffed. If the canopy was sized properly for the container, and the closing loop was that long, it wouldn't be tight enough to hold the pin or (most likely) trap the bridle.

    As it sits, it appears to be tight and far longer than it should be, so my bet is that someone was looking for a smaller container, or got a 'good deal' on that rig, or whatever, but in any case the canopy/container appears to be a mis-match.



    Thank you dave. I thought you were "bashing" the container type. I didnt look at the "whole" picture: size,main etc.

  15. Hello all, I have my CSPA Rigger "A" rating and would like to become a FAA senior rigger.

    I have 28 repacks total(ten supervised by cspa riggers).

    My question is; do i have to start from scratch, or is there a crossover program for foreign rigger ratings?

    Thanks in advance!

    There is no substitute for increasing the length of the lever arm. Ordinary mini risers really are not a good design. The tollerances are too tight. The mecanical advantage just isn't there. Booth actually had it right in the begining with the big rings. The aerodine riser is the smartest thing to come along in a long time. And frankly I don't know why it hasn't caught on. Pattent? If I was them I'd be selling rings to every manufatorer out there. If I was building rigs I'd be paying an extra $5.00 a rig to use them just like people used to do to Booth before his pattent ran out.

    And by the way, no, I don't work for them. Not a dealer. No motive here. But I am a good enough engineer/rigger to actually know how the math on this works. And I'm not just talking theoretical shit out of my ass. I've actually seen risers break there in the real world. Eather snapping the tape on the small ring or tearing it lose.

    Very good point Lee.

    Riggerrob was my examiner and told me about increasing the white loop. But yes the areodyne ring is a step in the right direction

    I have seen risers where the middle ring is not a circle, instead it is oval shaped and has an extra piece of metal in the middle. (almost like a figure 8, but not indented in the middle) What are these for? What is their benefit? Thank you.



    The purpose is to increase the mechanical advantage of the middle ring to make cutaways "easier"

    In all actuality if you increased the length of the white loop. The same effect will be achieved.

    Yes i also find it strange that he goes out of his way to complain about a dz opening up in fitzgerald when he had an opportunity to open up himself



    EXACTLY! Then he was going to make the DZO (who I don't know, so I'm not defending) "the most hated man in skydiving behind SR guys"? Your leasing a fleet of twin otters for a once a year 4 day boogie and your afraid a guy with a C-182 is going to put you under???




    I'll admit to letting my emotions get away from me when I wrote that, I was mad. Aside from that, I don't give a fuck what the two of you think of me.



    The purpose of the forum is to share advice and ask/answer questions and discuss issues. You obviously cared about what we commented about when you wrote that childish statement . It clearly shows your lack of professionalism.

    Yeah or he could just find another place to have the boogie.
