I'll bet he sure as hell wouldn't have 5+ wraps around his hands when he does.

Have you ever done crw? got into a wrap? I'm a crwdog and a canopy staller and have done 5+ wraps of brakeline to make a narly stall happen. Darwin recipient, maybe. How i've avoided 'going in' for such lewd acts of stupidity is to be done playing stupid above the decision altitude. When i've done the brakeline wrap on my hands, my ep's changed a bit to avoid 'going in'. what has to happen in this situation is to get the line removed from hands prior to decision altitude, obviously. then the ep's are back to normal. Been in 8 wraps and no cutaways because of wrap, wraps were cleared above decision altitude. Time and space and decision altitude is part of why I have'nt recieved the Darwin award yet for taking such risks.QuoteQuoteThat's certainly been my experience on the student canopies I've jumped. It took several (5+) wraps of the steering lines around the hands before I was able to get any kind of stall at all, and even then the wingloading was so light (~0.5) that I wasn't even able to get the tail to touch, let alone get the "big ball of crap" that I was going for.
Was it your task to do? Has it been given by your instructor?
If the shit hits the fan, how would you cut your crap away? Thats just like a nomination for Darwin award!

You're talking about winds when they do not matter

This is a classic example of why the first poster should go talk with his own instructors!
Skydiving: Almost 1 year Off the student status. Officially no instructors but I'm looking for shit to learn. Former instructors: mix ideas about the wind changing case.
Paragliding: Not having my license. Instructors: wind changing is BAD! They couldn't quite explain to me why but that's their teaching.
Anyway,
One guy from here wrote something that begin to make sense to me about that wind change thing. It was right here on this forum and that's Billvon in the post called "Flying in Turbulence". Search for it. Read the original post.
This is a PM that I've sent to Billvon about that post in Jun.2007 For all the bullshit happy fingers out there I think that Billvon can confirm if he got an email like this one or not. I have it in my sent messages. Billvon forgive an old retard like me for dragging your name in here but I'm just to stupid.

I've read your article from Safety&Training and I just wanted to thank you for the clear explanation. It cleared up a lot of things that I've beed instructed to do at a paragliding class and I didn't understood why they are true. My instructors told me just to take them as true.
Now I know why when I enter a thermal in the transition period I need to reduce the break input and/or to use the speed bar(front risers) in order to avoid a collapse. It's because my wing relative wind changed and now I have a higher angle of attack that can stall&collapse my canopy.
Thanks you Bill,
Jean-Arthur Deda.
Anyway, one debatable person could say: You know, that's freaking debatable because it's a thermal! And that's wind rising. Also that's paragliding and that's high aspect ratio wings and they are bad & shit, I mean I hear about collapse on those things all the time and besides things don't really scale!
OK, let's move on.
Gliding:
Quote
When landing, wind shear is also a hazard, particularly when the winds are strong. As the glider descends through the wind gradient on final approach to landing, airspeed decreases while sink rate increases, and there is insufficient time to accelerate prior to ground contact. The pilot must anticipate the wind gradient and use a higher approach speed to compensate for it.
http://en.wikipedia.org/wiki/Wind_shear#Gliding
debatable person: That's wikipedia and anyone can write shit there and it doesn't make it true. Hell, even I can write an entire poem right there on that page right now if I want and beside just a bit higher in that link they say about downdrafts in a wind shear and I'm sure that's what is causing the increase the sink rate.
OK, forget about all those things, kid. Use your common sense.
Walk with me on this one. Let's take a perfect horizontal wind but gusty. It goes from 40 km/h to 0 in less than one second. When the wind drops there's a transition volume, a gradient in wind. The wind gradient. I like that name. If the length of the wind gradient is smaller than you parachute chord I personally believe as an amator bullshiter (as other strong characters imply I am) that you parachute will collapse not only stall but collapse. Why? Take a look over the attachment. Now what's the relative wind speed for that wing in that condition? Not that easy now to say out loud a number!
That's a collapse. That collapse is not created from rotors or turbulence is just from the wind gradient itself.
In my simple and humble existence and at this point in time I believe that if the wind gradient is larger the effect will be less dramatic. Maybe not a collapse maybe just a stall or maybe just a change in relative wind of the wing that could make you sink. Something like Billvon suggested.
Moving on!
Let's take a DZ. An ideal DZ. No obstacles. LZ larger than time. A sweet 80 km radius of objects free landing zone. A yeah with "experienced" instructors that just don't believe that wind change can affect anything more than your horizontal speed relative to earth. Take some students that are teach by the same believes as you. Wind doesn't count. Wind is not even gusty at that point. Nothing bad. One student like me jumping with his shy wing goes and jumps trying to learn and get better. He flares low and fast. The wind drops fast as he flares. The relative wind of the wing is now 20 km/h and not 40km/h. As I flare nothing happens. I don't feel any resistance in the toggles as I usually do. I hit the ground hard as I'm just about half flare. I go in because the instructors from that DZ failed to teach me something and more than that because I usually flare fast and lower there's not going to be any lessons learnt. Any human there will assumed that I've just flared badly.
This is a classic example why people like should go to schools to get educated.
Now, to all the happy hunters out there:TRASH ME, KILL ME but mark my words: there's something going on the wind changes case and this thing is here to stay. Ignorance will not make it go away!

I have not doen CReW yet, but I hope there is a difference betwwen an experienced CRW dog and a student.... Can you see some?
Hey phoenixlpr, that's a good question.
How would you cut your crap away?
