How about using polygon modeling, such as modern 3D game engines use, then compute totals using the individual values determined for each polygonal surface. I expect the results would be accurate enough to get a viable model, or at least be a good place to start. I wonder how much the actual performance of the whole model would diverge from the predicted performance of the sum of its parts. I suppose that answer will have to wait until both abstract, software, and physical, wind tunnel, models are made and tested. Cheers

Regarding the flight angle, the goal of Atmonauti is to fly parallel headfirst or feet first in to the relative wind. That particular angle will depend on, among other things: Body weight, cross-sectional surface area, and how much vertical lift the atmonaut is able to generate by arching. I also believe the goal is to maximize flight time rather than horizontal distance. Cheers

It appears that the outer cells are pressurized only though the cross-ports. I wonder how fast it turns...

I check my gear thoroughly before putting it on, and check several times on the way up, that the hacky it still snug, leg straps are still snug, and that the RSL is still hooked up. Before I exit, I'll reach back and check my main pin to make sure it's seated all the way through the closing loop, and that my reserve flap is still closed. Cheers

I did more than four hours in the tunnel, and learned fine control, before I ever jumped. So, I missed out noticing how much sliding and drifting experienced skydivers do, when going into the tunnel for the first time. I have heard people talking about it though. Cheers

I think this was the one he was talking about. He claimed to have started jumping in the late '60s, and I remember the word 'sled' from the same conversation. Thanks, that's a neat site too. Cheers Late addition, I also remember he said took it to termainal and it slamed him pretty hard and ripped some of the reefing loose.

Anybody got a picture of a split-tail canopy? Stories would be appreciated too... I heard they turn rather abruptly, that's why they stopped making them. Cheers

The tunnel is very close to actual freefall. There are some sutle differences: The air in the sky is cooler and fresher, and I think it feels a bit smoother too. One other difference is that in the sky you are wearing a rig, that is twenty or so pounds. If you train in the tunnel without wearing additional weight, you might notice differences due to the higher fall rate in the sky. I did. I've flown up to 3 minutes at a shot in the tunnel, and up to 20 minutes out of an hour. By far I find the sky more fun, but the tunnel is a good place to build up your skills due to both the extended flight time and video options available there. Cheers

"Lock, Stock, and Two Smoking Barrels" and, "The Fifth Element" Simply overwhelming humor in both...

I use TAS too, because I lack a compelling reason to do otherwise. Hence, this poll. As I understand it the SAS is usefull for comparing fall rates which occured at dropzones with different ground attitudes.

I've been wondering which setting more people use for their ProTrack. So... Which setting do you use, and why? Cheers

Fee-nine, did you say?

Hahaha... You qualify for... Team Anvil!

Actually, I think that was my max. Hmm, Let me check... Average on the 175 max, attempted stand, jump was 150. And my batteries just died. So, my average on the 160 max, held stable sit, jump was probably around 145, My average on belly jumps is about 125 with a 135 max. Cheers

I still pull at 5.5 because I really enjoy playing with myself, oops, I mean my canopy Spirals are F*ing awesome. 5 spirals on my Spectre 210 = 1000' And it's so f*ing cool pulling out of the dive, at like 60+ mph, after letting up on the toggle. Cheers

Dealing with your emotions is half the fun, maybe more. As it been said before, skydiving is mostly mental. In any case, congrats, and try it sober next time. Cheers BTW Has your friend any spare zanex bars? I hear that a zanex bar and a gell tab is a ticket to heaven Just kidding... ADDITION------------------ Come to think of it, maybe that's why people like to drink or smoke before jumping, because they have trouble dealing with their emotions/anxiety otherwise. Hmm...

I think I'll go back and see it again

I'm a slow faller. I sit at 160 and only got up to 175 durning my last attempt to fly a stand. Cheers

I just sent my drop in the hat

I guess, I'm gonna haf ta get a hard copy of the SIM. The PDF version is just too much trouble to read at length. Cheers

How could you possibly do that??? On my first day, I woke up at 4am too excited to go back to sleep. So, I ate breakfast and drove to the DZ. I got there at like 6am. One person was there, sitting under a light reading the paper with his morning coffee. So, I just walked around to two hours, 'till people started showing up

This thread has raised a question for me: According to the rules, who is allowed to disconnect/reconnect canopies and rigs? I mean if the risers are left connnected to the canopy and all that is being disconnect/reconnected are the two three rings. I have done this several times myself for the various demos I've had. The demo's came attached to risers. The second time, I noticed things were a bit wrong. This was my canopy that I was re-attaching after a demo. The brake lines twisted around the other lines. One dimwit actually suggested that I untie the toggles, untwist the brake lines, then reattach the toggles. I just knew that was wrong, because it got that way with everything still together. I eventually straightened everything out by flipping the end of each riser up and between the seperate front and rears risers. Then, I took it back to my rigger, so he could make sure everything was right. He said I had a 'flip-through'. Apparently, the person, who I had asked to show me how to rigger roll, flipped the risers through in the process. I actually recall seeing him do that, when he was stetching out the canopy and lines before rolling it, but was clueless about what that meant at the time. My rigger then showed me a simple way to check things out, if the canopy was left attached to the rises for the whole time. This involves finding the lines attached to the stablizers, tracing them back to the risers, and making sure that they go all the way back to the rig without twisting around any of the support lines, and that they attach to the outside edge of each riser. Cheers

LOL, there's three guys at my home DZ that belly fly at about 150 MPH!!! I call 'em Team Anvil Just try to hook up with some other fast fallers
