Oke 0 #1 January 17, 2007 Icing....seem possible...numbers add up. What's your take on popping through cloud in the winter time and picking up some ice on your body? Or maybe the numbers don't add up? Too fast through the layer of cloud and not enough time to pick anything up? I'm sure one could pick up icing...any stories out there?Not that winter jumping is somthing I'm game for.-Adam Oke Quote Share this post Link to post Share on other sites
quade 3 #2 January 17, 2007 It's happened to me and I live in and jump in southern California. Not that you're likely to accumulate a lot of it, but I've had enough on my goggles to block my vision.quade - The World's Most Boring Skydiver Quote Share this post Link to post Share on other sites
slotperfect 7 #3 January 17, 2007 I have encountered ice in freefall, but it involved being pelted with little chunks of it. I just talked to a gent yesterday who has almost 17,000 jumps in nearly 40 years of jumping - it happened to him once, his jumpsuit etc. icing up in freefall.Arrive Safely John Quote Share this post Link to post Share on other sites

I had a full-face helmet and was focused on the guy keying the exit, so I didn't notice it at the time, but one of the TI's watching told me my upwind side was solid white before I let go of the plane."There are only three things of value: younger women, faster airplanes, and bigger crocodiles" - Arthur Jones.

zappman 0 #6 January 18, 2007 Once i went thru an ice cloud, i had an open helmet (long live freefly). I entered the 'ice zone' at 11k, i pulled at 5k and i was still bombarded with hail, around 3k the hail went to rain, a lot of rain. I was soaking wet, my face was red and totally covered with bumps, like i had a strange desease. People asked me why i didn't go on my back...I DID but then the hail was impacting the back of my neck. So i lay in a kind of foetus position for 6000ft And yelling in freefall: aaawwf*cksh*tdamn this hurts!!! 20 minutes later it was blue skies again and i had to jump to dry my gear Quote Share this post Link to post Share on other sites
Zing 2 #7 January 18, 2007 I think the military has documented accounts from ejected pilots who encountered ice in its various forms in the atmosphere. There was abook called "The Man Who Rode Thunder" by an Air Force pilot who ejected into a severe thunderstorm and experienced mother nature's weather phenomenons first hand back in the early 60s. I'd love to find a copy of that book again. There are several mechanisms by which ice will form on a surface, and a jumper freefalling into the proper conditions could pick up noticeable amounts of ice in a few seconds. I've had it happen skydiving, but the ice was less a factor than the poor visibility inside a very dense cloud. Flying a King Air, IFR somewhere over Louisiana a few years ago in an area with no forecast icing conditions, I flew into a patch of clouds that coated the windscreen, wings and tail and pitot tubes with a half-inch of ice in 30 to 45 seconds. By the time I turned on the pitot heat, foolishly left off, and cycled the deice boots, etc., the airplane was clear of the icing area and we proceeded IFR in the soup to Mobile, Ala. without seeing any more iceZing Lurks Quote Share this post Link to post Share on other sites

DougH 270 #10 January 20, 2007 QuoteYes. It gets wet. And so do you. Don't. While amusing, chuckle chuckle, that doesn't answer his question: "does the canopy fly differently when wet?". I have gone through rainy conditions twice and I didn't notice any difference in stability, glide, or flare on landing even with the canopy considerably wet. I am curious about this answer also. I have iced up my fullface, but never my jumpsuit. Thats shit hurts.

I've picked up ice on high altitude jumps, but the worst problem I ever had with icing came from me. During the 2002 300-way attempts, we got 26,000 feet on one jump. Exit temperature was -34F. I exited, took a breath in, breathed out - and my visor went completely opaque with frost. Fortunately my visor doesn't fit very well and I could look out the crack between the top of the visor and the helmet. Other people were taking their helmets off and opening their visors in freefall to be able to see, with limited success. (Note that at -34F your eyes freeze too.) Needless to say we didn't get it on that jump. Quote Share this post Link to post Share on other sites StevieBoy 0 #23 January 24, 2007 QuoteI have iced up my fullface, but never my jumpsuit.
