Hooknswoop 19 #2 August 23, 2006 TSO C23D requires that a reserve canopy not exceed 24 FPS decent rate and the total velocity not exceed 36 FPS at maximum operating weight in the post-deployment configuration brakes set). How hard of a landing is that? Derek Quote Share this post Link to post Share on other sites
mjosparky 3 #3 August 23, 2006 Quote36 FPS at maximum operating weight ............How hard of a landing is that? Under an overloaded reserve you might be looking 40 fps. or more. That is around 27 to say 30 mph. That is damn hard even if the first thing you his is horizontal ground. If it is an vertical obstacle you will be in deep do do.My idea of a fair fight is clubbing baby seals Quote Share this post Link to post Share on other sites

piisfish 135 #5 August 23, 2006 If I had been unconscious on my Cypres save, I am quite sure I would have survived (unless my head struck something hard, had to ditch my helmet), provided the plane wasn't coming in for landing because the reserve would have been flying across the runway at low altitude.scissors beat paper, paper beat rock, rock beat wingsuit - KarlM Quote Share this post Link to post Share on other sites

Aerodyne has 220lb max for the 99-135 - wouldn't a 2.0 WL be substantially faster than 36fps? Quote Share this post Link to post Share on other sites

Travman 6 #10 August 23, 2006 The latest issue of Australian Skydiver Magazine has a story about a guy who collided with another jumper on a wingsuit jump which knocked him out and sent him into a steep dive. His cypres fired and the force of the opening fractured his C2 to 6 vertebraes and split the body of his C7 (spinal cord OK!!!). His reserve stayed on windline and he landed softly. He is taking a year off jumping to heal. Quote Share this post Link to post Share on other sites
mjosparky 3 #11 August 23, 2006 Quote24 fps is equivalent to falling from 9 ft ... At 24 fps you are traveling at 16 mph. That is faster than you can run.My idea of a fair fight is clubbing baby seals Quote Share this post Link to post Share on other sites

woodpecker 0 #13 August 23, 2006 Had this happen in texel two years ago. Jumper with no helmet on smashed into the door while exiting and was rendered unconscious. Cypress fired, all he did was roll an ankle on landing. Went to hospital, no breaks, just a bad sprain.SONIC WOODY #146 There is a fine line between cockiness and confidence -- which side of the line are you on?

BIGUN 1,050 #14 August 23, 2006 Too many variables for a "Yes" or "No." What I do know is; I have very little chance if I don't have an AAD.Nobody has time to listen; because they're desperately chasing the need of being heard. Quote Share this post Link to post Share on other sites
AndyMan 7 #15 August 23, 2006 Where I jump in the midwest, literally smack in the middle of the largest cornfields you could possibly imagine...? Yup. Landing would likely either be soft mud in the spring or tall corn in the summer. _Am__ You put the fun in "funnel" - craichead. Quote Share this post Link to post Share on other sites

Max weight., so for a 99, that would be 220 pounds suspended weight. It doesn't account for any harness turns, which may or may not happen. I brought it up since it is a major factor in whether or not you get hurt, how fast you would be going under the reserve. 24 FPS is 16.364 mph 36 FPS is 24.545 mph If you are under the max TSO wweight (as I read AS8015b, someone correct e if I am wrong), and not inducing any harness turns, you should be below these numbers. Altitude, harness turns, etc will increase your speed though. I am not trying to answer the question, just make it easier to answer. Derek Quote Share this post Link to post Share on other sites

linestretch 0 #19 August 23, 2006 I like my odds with the AAD. Personaly know 2 sleepers that had the AAD save them. One hurt her back, the other cut her chin pretty good....but both are alive and jumping (that I know of). I see it like a seat belt.my pics & stuff!

Dolph 0 #20 August 23, 2006 No idea. Having an AAD increases my chances. Weight shift in harness due to being unconscious will make the canopy turn. Under my main I can swoop using only harness turns. My reserve will be moer docile, but whether it is docile enough I don't know. Quote Share this post Link to post Share on other sites
nathaniel 0 #21 August 23, 2006 Quote 24 fps is equivalent to falling from 9 ft ... When I was in college, a student died after falling off one step, having hit the base of his skull when he landed. That said, around here it's mostly tilled cornfields and beanfields, I think you'd do reasonably well, if you didn't end up face down and suffocate in the dirt/mud.My advice is to do what your parents did; get a job, sir. The bums will always lose. Do you hear me, Lebowski? Quote Share this post Link to post Share on other sites
kkeenan 13 #22 August 23, 2006 I think the main point here is this: If you pick your reserve with more consideration to its packed volume i.e. "Is it properly small and cool", then you may be jeapordizing your safety. If you land unconscious under a small, overloaded reserve, you have a greater chance of getting seriously injured or killed. Sure, it's possible for a skilled canopy pilot to pull off a landing under a reserve at a wingloading of 1.9. But, if you're hanging limp in the harness with visions of sugarplums dancing in your head when you cream into a Wal-Mart parking lot, then none of that skill will help, and you may never wake up. It's common knowledge that many folks jump reserves that are way over the wingloading that would be considered safe in the event of this scenario. But this is a sport of individual choices and risk assessments. I make my equipment choices and you make yours. No problems. Kevin_____________________________________ Dude, you are so awesome...

winsor 186 #23 August 23, 2006 QuoteSo if you are unconscious under your reserve during landing...do you think you will live through it???? Assuming that you dont hit any objects on landing... This one of the reasons I have 99 sq. ft. mains with 218 sq. ft. reserves. Even if I am conscious under reserve, there is a chance that I went to silver because of a broken collarbone or something similar (breaking a collarbone in a blown exit or good old fashioned funnel is easy). If I can't steer or flare properly, I want a nylon overcast above me. Another consideration is that a CYPRES is going to have me open at 750 some-odd feet. Even if I can steer and flare, there is a good chance that I am going to be somewhere that does not have the requisite runway area for landing any kind of HP canopy. Being under something I can sink into someone's back yard, or land in trees without getting killed, is a good thing. Little reserves are better than a PLF at terminal, but there are circumstances under which the results are about the same. Blue skies, Winsor Quote Share this post Link to post Share on other sites
Darius11 12 #24 August 23, 2006 I would. I jump a Saber 2 230 and a PD 253 reserve. Loaded at a little over 1 to 1 So it would hurt and most likely I would be broken but alive...............I hope.I'd rather be hated for who I am, than loved for who I am not." - Kurt Cobain Quote Share this post Link to post Share on other sites
apollard24 0 #25 August 23, 2006 winsor- my SO does the same thing, he flies a Vengeance 120 main and has a 175 reserve. He wanted a larger reserve just incase he was hurt under a reserve. I would hope that I would survive my reserve ride. Im not loading quiet 1:1 on my 135 reserve. Can only hope for the bestBreathe out so I can breathe you in...
