It's called chaos theory Given 460's BKG, he could give you some insights. Edited to add: That is if you consider a BASE jump a deterministic system. If a BASE jump is a non-deterministic system then we are dealing with quantom chaos. In the end as 460 pointed out, you'd better using your feel! Memento Audere Semper 903

Bill, Thanks for stepping in. However, a gliding main does not have all that airspeed otherwise those jumpers who cutaway with the skyhook and slider off reserves would have been hurt by the deployment and having seen the video, there does not seem to be all this airspeed. Don't get me wrong, being a fan of the RSL I see the superiority of the skyhook and I wish I could install it in all my SD rigs. The problem I have is this 70' deployment. I have already heard of skydivers arguing that because they have a skyhook they could cutaway at 100' and survive. That it just ain't gonna happen! At least not with a slider up reserve. 100' is ridiculously low. Knowing the little I know about canopies, I would say that a ~250' deployment is more of a realistic figure for the skyhook. Again my hat's off for the invention but I just would hate to see a wrong message being delivered and causalities to follow. just my .02 Memento Audere Semper 903

Bill, A S/L BASE deployment burns up about 75'. That is possible due to specific canopies designed to pressurize very quickly and packed without a slider. I do not understand how a SD reserve packed slider up can achieve a full inflation in only 70'. Even if the skyhook was virtually anchored to the sky (and it's not) you still have to deal with a reserve that uses a sail slider, that it is not free-bagged, and not designed to open incredibly fast. I just don't get it. Memento Audere Semper 903

Some of the variables you mentioned do apply to WS flight some don't. Nonetheless, weight seems to be one of the most critical variables when it comes to L/D. I am not an engineer but I remember few things from comparative physiology. Let’s talk about few features about birds that relate to weight. Bones: hollow and elastic, made of much more cartilage then human bones. Lungs: always inflated to keep the trunk always is a predetermined shape. Feather: light, strong, they provide shape to the airfoil and insulation to the core. Fat: non migrant birds are lean (~3% BF). Migrant species can have up to 100% BF! This fat is not for insulation (see feathers) but only for energy. Many migrants start to pig out about three weeks before their journey increasing their body weight by almost 100%. This added weight assures enough energy to complete the journey. However now the “flying pigs” being so heavy they have to flap they wings at a much higher rate. This rate goes down as the journey continues due to the weigh loss. Non-migrants, especially big birds, like raptors are very lean (2-3% BF) and they do not like to flap their wings, one because their wing span is quite impressive (some close to 9’) and two because they do not have the energy resources to flap for a long time. The solution? Soaring. When I used to Hang-glide I was always looking for falcons, eagles, and such to spot thermals. So here is what we have to do to improve WS performance: bone transplant with hollow bones and while there, get few extra feet of arm length; reduce BF to 2-3%; Keep lungs inflated for the duration of the flight. Trade in the WS for feathers. All these should not be a problem for most of us Memento Audere Semper 903

I've PMed sangiro few times about this. I would like the Gear and Rigging forum on DZ to be split in two forums and have only riggers to be able to post in the rigging forum with everyone having read privilege. Just my 0.02 Memento Audere Semper 903

I was talking about glide ratio not flaring performance. I have yet tried to land my suit Anyhow, Atair found out that @ 4.45 WL the glide ratio increased. Here is the thread: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=1605132;search_string=glide%20ratio%20cobalt;#1605132 Memento Audere Semper 903

Everyone gets what they want one way or the other. I got my hands on a Fury 220, no BKG check on that one! I got my hands on a 1980 all fucked up Warp III. Got rid of the container and pluged the Fury to the harness for an "unpacked" set up only. A guy with 0 jump could have done that and go off the closest OBJ. Everyone gets what they want one way or the other. Memento Audere Semper 903

First you have to define "performance". Robi among others already talked about this issue several times. My understanding is like having a 200Lb person under let say a Stiletto 97 and a 120 Lb under the same wing, for the sake of the argument. If they start flying on a straight line next to each other in a no wind day, chances are the heavy guy will fly faster but in the end the glide ratio is the same and both jumpers will land close to one another. The glide ratio is a property of the design of the wing. The higher the WL the faster you go down the slope but the glide ratio stays the same. Of course in real life there are things, like wind, drag, and such, but the basic idea stays. I believe the same applies to WS. Two identical WSs, the one with higher WL will fly faster than the one with lower WL but the glide ratio will be the nearly the same. I think any gain in lift generated by the extra speed by the heavy guy is canceled out by the extra drag. Again in the end all we should care performance speaking, is glide ratio and that is more an intrinsic characteristic of the WS design and body position than WL. Of course I could have all this wrong! Just relying on intuitions is not science and without any hard data you always end up speaking out of your ass! Memento Audere Semper 903

Hey guys, My wife got her Phantom last night! See the pics. I was more excited than she was! First let me thank Robi, Robert and Kathy, and Jay. Great CS! The suit is fantastic. I fly a S3 and I could clearly see the improvements in constructions Robi made over the years. The padding on the leading edge of the arm wings is absolutely sweet. I wish my S3 had it. I really like the new handles of the cutaway system. The swoop cords are adjustable and beefy. The booties are made out of premium leather. But they are the details of the suit that just blow me away. The reinforcements, the bartacking, and so forth. For instance, the sliver PF logo on the back of the leg wing is not stamped, it is sewn on from three separate pieces of silver fabric, just too much! As for the design, the leg stance is much wider than my S3 but the wing does not come all the way to the booties. I bet this gives the suit great stability. The arm wings are just marginally smaller than the S3 and the grip pockets are a superior design. If it flies as good as it looks I won't be able to catch up! There is only one problem, it won't fit me! I'd better start saving... Memento Audere Semper 903

I heard that he broke his R hand and wanted to continue jumping...That's what I heard... I saw Miles going for the wrong side but he's pretty quick switching over. Memento Audere Semper 903

I would like to see one even though in the end it's not going to change a thing, just more work for the moderators. Look at Gear and Rigging, for instance. Some thread starts with a great topic, few great replies, and then a pissing contest. That's the nature of DZ.com: "my dick is so much longer than yours". What we really need is a filter for mindless discussions and direct them to the "bonfire" and such Memento Audere Semper 903

You need to suntan dude! Glad you're OK, beside the scratches, those ain't scars! In Z-hills once after a WS jump and a super long spot following an off field landing, I came about 2 yards from a barb-wired fence covered in bushes that I could not see...however, sooner or later thought anybody will bite the dust...
