Safety Seminars

[Vallerina 2]

The club pres. and I had a conversation the other day about finding seminars online. We've heard a couple of good ones here and there, and we'd like to present them as best as we can to our club members who haven't had the opportunity to go to other dz's and gain the same knowledge. Does anybody know of any good seminars available online (for example, Brian Germain's talk on canopy flight is available online). Okay, thanks!

CSPA has an extensive "Know Your Gear" outline, but currently it is only available on paper. If you bug me enough, I may figure out how to put it on-line.

That sounds perfect for what we are looking for! Since we're aiming our talks for people who are just entering (as in they may have only one or two skydives), don't worry too much about putting it online (although I would love to read it for my own personal sake.) Actually, any basic seminar/essays/whatever other information that is nicely put together so we don't have to do too much work would be appreciated.

There are a couple of excellent articles/seminars on PD's website - http://www.performancedesigns.com
And if you haven't already, check the Safety and Gear sections of this website - lots of good information in the articles there too. pull and flare,

Here is a graduate seminar outline I put together a few years ago: (attachement)

Great article Bill. I have been looking for something like that for a while. I saw one thing in it though I disagree with, regarding exit order. It says the freefliers should exit first, which I know has been debated and beat to death. I believe the freefliers should exit last. Head-down and headup freeflyers retain the forward speed of the aircraft longer. The RW group exiting after can end up straight above or even on the opposite side of the freeflyer. I got this from Brian Germain's freefly seminar. He did a very in depth talk about this which made absolute sense. But I know this will be different at different drop zones, so I just accept the home teams rules wherever I happen to be. As long as proper separation on exit occurs I think either way can be safe.

That's fine. The only problem I have with that is that the higher the wind, the further the freeflyers will get pushed under the RW people, since wind pushes RWers further back. That means that if freeflyers exit after the RW people in, say, a 40 kt headwind at altitude, they have to wait a _very_ long time (20-30 seconds) to give the RW group ahead of them enough separation. Many freeflyers are unwilling to do this. That's one reason I try to give a graduate course like this - so people are aware of the benefits and hazards of each method.
We put freeflyers out first because we usually have 20kts or so of wind at altitude, and we run jump run into the wind. In those situations, putting freeflyers out first gives you built in separation between freeflyers and RWers. Difference in throw is an extremely minor effect, amounting to a few hundred feet at most - and you need separations closer to 1000 feet between groups to be safe. Besides, one blown exit and the effect you're counting on is gone.

Here i've got a graph that a jumper put up at our DZ. is theory is that Fflyers are expose to the wind less time than RW. He suggest to put RW out First.

Vallerina & all the others who are interested in this:
On John Kallend's website you find some great resources regarding this topic. There is also a power point presentation that everyone should know who is interested in exit order, separation and freefly or rw first or vice versa or whatever :-)
