    100TH!

    I'm coming to Burnaby this weekend (finally). Maybe I'll even bring some STIers with me. You know what that means, don't you -- Toggle Whippin' Yahoo Skydiving is easy. All you have to do is relax while plummetting at 120 mph from 10,000' with nothing but some nylon and webbing to save you.

    Built in turn

    Believe it or not, I've done steps one through four and noone still has any idea what's causing the turn. Until now, that is. In fact, I'm gonna see my friendly neighbourhood rigger later in the day. As to the chute turning into the wind, that sounds impossible. When a canopy is in an airmass, it's irrelevant which way that airmass is moving, no? -- Toggle Whippin' Yahoo Skydiving is easy.

  5. I just came up with an example on why the 45 degree method does not work. In fact, I'm going to print it out and show it to some people at my DZ. Here it is. You are in a C182. A 4-way exits. They ask for a cut. As they climb out the plane is moving maybe 55mph, just hovering above stall. The 4-way is gone and you don't bother with a powerup, you just look out the door. Ok, 45 degrees, you're good to go. Now, a little bit of math. The plane-4way-vertical triangle has one 45 degree angle and one 90 degree angle. Therefore, the vertical distance the 4-way travelled from the plane is the same as the distance the plane travelled since their exit. The plane is going at 55mph, or 88.5 km/h = 24.6 m/s. How fast will freefallers reach 55mph downwards? 5 seconds? Does 125 meters sound like adequate separation from a 4-way? EDITED TO ADD: I forgot to explain this: when the 45 degree thing happens, the average speed of the plane is the same as the average speed of the jumpers (distance travelled over time spent). The average speed of the plane is just 55mph. The average speed of the jumpers is small at first, but grows very quickly. Their average speed will reach 55mph very quickly. The point is, in the situation where you want a longer exit separation, the 45 degree thing will give you less separation. Not only does it seem not to work, it does the opposite from what you want! -- Toggle Whippin' Yahoo Skydiving is easy.

    Built in turn

    I will talk to my rigger tomorrow, maybe have someone more experienced jump that canopy and make the call. Either way, I will let this message board know, it can be educational. As to the toggle input, I need to pull the right toggle maybe half way down the riser. -- Toggle Whippin' Yahoo Skydiving is easy.

    Built in turn

    Ok, this is kind of long, but please bear with me. I have a Triathlon. It was built before they did that update, but the previous owner relined it, so the lineset has been updated. I've recently started jumping it and I'm noticing a built in left turn. It's a fairly slow turn, maybe a degree a second or so. If I wait a long time I will start drifting off heading, and it's just severe enough to require correction on final approach. This is, of course, annoying, since I need to keep the right control line under tension to fly straight. It doesn't seem to be my weight in the harness because moving around in it does nothing (the Triathlon is completely square, planform factor 0). Two riggers checked the length of the lines and found nothing except a 1/4 inch offset in the control lines, which will do nothing anyway because the slack in those lines is much greater than 1/4 inch in full flight, and the canopy is turning in full flight. Finally, I inspected the shape of the wing. Basically, I checked that the stitching on the canopy is symmetrical. Here's what I found. Basically, I start from the center cell and work outwards. So I would take the 3rd and 5th cells and check that all the stitches are the same length. Same with the 2nd and 6th, etc. I didn't check every single seam. I checked the nose and the tail, and they're symmetrical. Then I started checking the ribs. I compared the outermost ribs on the outermost cells (the 1st and 7th). These are the ribs that have no canopy to one of their sides. See my poor excuse for a drawing for more explanation. One of these ribs is about half an inch shorter than the other. The left rib is shorter, so that side would be generating less lift and my weight would effect it more, bringing the left half of the nose of the canopy down and causing a slow left diving turn. The other ribs seem even. My question is, it's a pretty small difference. Could this be what is causing the turn? If so, is there an easy way to fix it without ruining the performance of the airfoil and/or endangering the lineset? I was thinking of tying a knot in the other A line to pull down the right rib until they balance, but I'm not sure what effect that would have on the strength of the line. Do I have to send it to Aerodyne or could a rigger undo the bartack and move the line attachment point? Thanks for reading this far

    You're not helping!!! Actually, that's good advice if I ever heard it. I was going to go over all my freefly videos and watch people sitfly.
