    My reasoning is as follows, let´s take year 2013 as an example: 24 fatalities in 3.200.000 jumps, in other words a fatality every 133.333 jumps. That doesn't sound so bad, doesn't it? In fact if you give that number to someone who doesn't jump they might say the sport is very safe. This is because we assume that we have a chance of 1 in 133.333 (0.00075%) of getting killed, and while this might be true for someone that only does a single jump in his whole life, it's not even close for a regular jumper.

    I want to be an active regular jumper so I wanted to know how this odds apply to me. I assumed an active jumper does around 10.000 jumps throughout his life. If this is the case then the statistics change from 1 in 133.333 (0.00075%) to 10.000 in 133.333 (7.5%). That's right!: If everyone has the same chance of dying per jump and you want to do 10.000 jumps in your life, you have a 7.5% chance of getting killed! How fucked up is that?



    Your basing your math of 10k jumps over a 3.2 million jump year and not over a lifetime of jumping. If that was over say... 30 years then it would be 96 million jumps if the jump/year rate was the same. I you were jumping 10k times a year than it would be equivalent.
    So, say you logged 200 jumps last year. That means you had a 0.15% chance one of those deaths would have been yours.
    Lots of other factors like do you swoop? Do you AAD? Do you RSL, Do you CReW? all play factors as well. A conservative jumper's stats would decline while an aggressive down sizer / swooper's stats would climb.

    Because to have this done legally would mean that a Master rigger had to do the work after getting field approval from the FSDO and submitted test documentation and drawings showing that the changes do no impact the function of the device and container. This would mean that Airtec or AAD would have had to actually supply info to use for the 337 form that needed to be submitted. Field rigging with out proper testing has lead to issues in the past and without having Airtec/AAD approval that moving this does not impact their units at all and that they would be covered under the same certifications.



    I may have been unclear. I wasn't suggesting an overzealous swooper / rigger team take this on themselves but the manufacturers. Special order maybe. AAD manufacturers offer the equipment and container manufacturers provide the routing via omfgimgoingsofast.swooping.com

  5. So it seems as if the only drawback was it was toooooo easy to turn on/off. Accidentally at times. Seems like a pretty straightforward design fix. Going through the menus of a Vigil or Cypress would probably be task saturating but again, seems like an easy design fix. I may be wrong. Longer control cable and cutter cable and a software update for the start-up / shutdown procedures. A container modification for routing the control cable. Its seems as if there is a market for it.

  6. Just 0.02 from a non-swooper, but I wonder why AAD and container manufacturers do not work out a way to make the controller accessible under canopy. Like a mudflap, chest strap, leg strap or w/e so they could then be turned off just prior to initiating their turn. Again, not a swooper but it seems to me that there are swoopers who do not jump AADs due to similar concerns and IDK if this is a viable solution to some of them.

  9. With the development of newer military static line parachutes there have been "3 ring" versions along the way throughout testing. However, there are no U.S., static line, military static line parachutes currently using the 3-ring. They use a male/female canopy release assembly.

  12. Not really something "new" but an alteration. I kinda feel like I'm tossing a 2 dollar idea into the wind but.... A way to run AAD remotes to the chest strap or leg strap. I'm no swooper but from what I've gathered is there is a sub-group who rather not use / turn on AADs when they plan on swooping. Now they can turn them off under canopy just before they set up for landing.
    It would be simple enough to do.
