Fat lot of good that did too. I didn't say that is what he is saying, I asked if that is what he is saying, big difference. Derek

Let me see if I have you opinion right: 10-way speed is too risky for you without an AAD. 10-way speed is not too risky for you with an AAD You depend on your AAD to mitigate the risk down to the point of it being acceptable again to you. You are OK with doing 10-way speed dives and the chances of a collision as long as you have your AAD in the event a collision is so severe you are unable to deploy your main or reserve and live to deal with the injuries that the collision and subsequent landing caused. Someone that drives through red lights with airbags and seat belts is exercising good judgment because they are utilizing safety equipment. Derek

Mode C is required within the 30-m mode-C veil, which extends beyond the class B airspace. A radio is required in class A,B,C and D airspace and for parachute operations. Derek

They both do. Derek

But then you don't get a 4 and 8 year inspection either. A rig that didn't need to be inspected every 120 days would be cheaper to own, but wouldn't have 120 day inspections either. As for the life span, I can see it for a life-saving electronic device. Nothing lasts forever and components wear out. Derek

As of 11-23-2004, the FAA reduced the number of written questions from 305 to 118 in the question bank. On 2-17-2005 the FAA again updated the question bank without changing the number of questions in the question bank. The questions can be found at http://av-info.faa.gov/data/airmanknowledge/rig.htm A few questions I found interesting: 8. A44 RIG Which of the following is privileged to perform alterations to the auxiliary canopy of a single harness dual parachute pack to be used for intentional jumping? A) The owner of the parachute. B) A certificated and appropriately rated master parachute rigger. C) A certificated and appropriately rated senior parachute rigger. 22. A44 RIG Which of the following may alter the auxiliary parachute of a single harness dual parachute pack? A) The owner of the parachute. B) A certificated master parachute rigger. C) The person who intends to use the parachute. 23. A44 RIG How many of the following may alter the auxiliary parachute of a single harness dual parachute pack? (1) The owner of the parachute. (2) The person who is to use the parachute. (3) A certificated senior parachute rigger. A) None. B) One. C) Two. 30. A44 RIG A person who is authorized to perform alterations to parachutes must record which of the following alterations to a single harness dual parachute pack? 1. The main parachute. 2. The harness. 3. The auxiliary parachute. 4. The auxiliary parachute container. 5. The main parachute container. A) 1, 2, 3. B) 2, 3, 4. C) 3, 4, 5. 55. P38 RIG What happens to the pilot chute of a square main canopy that has fully opened? A) It remains inflated. B) It trails behind the main canopy. C) It drops through the vent and hangs inside the canopy. 70. P56 RIG Reserve closing loops are sewn together with what type stitch? A) Straight (301). B) Zigzag (308). C) Bartack (392). 84. P56 RIG What is the best ratio of pilot chute area to main canopy area for deployment speeds up to 150 knots? A) 5% B) 3% C) .5% Derek

Here on DZ.com. If we agree that driving riskier because you have an airbag is silly, then why isn't doing riskier skydives because you have an AAD silly? Derek

Would you think someone with 10 jumps doing a 300-way is wise because they are jumping with an AAD? How come I can’t find anyone that will drive two identical cars, one with airbags and one without any differently, but I can find people that will make a riskier jump because they have an AAD? What is the difference? If someone says that a 100-way has more risk than benefit for them,but goes on a 100-way because they have an AAD, doesn't that defeat the concept of a back-up device? Derek

Really? "I won't do freefly jumps with newbies that are learning to freefly until i get my cypres back. The chances of jumping with someone that isn't yet stable just isn't worth it to me." "Once upon a time I did a bunch of 10-way speed jumps without a CYPRES, using a borrowed rig (since mine was not available). I have since decided that was pretty stupid, given the nature of 10-way speed, and now I won't do it without a CYPRES. " There's two that both and there are a lot more. It is the "BECAUSE" that people are missing and misunderstanding. Derek

http://www.tub.net/safetytips.htm "Remember – GFCIs are a “back-up” safety device Consumers should consider the GFCI as a back-up safety device, not a replacement for common sense and prudent behavior whenever using electrical products. Wherever water and electricity are present, consumer need heightened awareness and should follow the safety instructions that came with the appliance." Do I need to explain the analogy? Derek

And I haven't disagreed with that. I'll say it again. Going on a riskier skydive BECAUSE you have an AAD means you are relying on it and it is no longer a back up. I don't see the difference between driving a car faster because you have an airbag and going on riskier skydives because you have an AAD. Can anyone explain the difference? Does anyone think it is OK to not treat an AAD as strictly a back up? Derek

Yes, and you haven't answered my questions. Derek

You misunderstand what I am saying. Derek

I would agree IF he wasn't using the AAD to reduce risk in order for it to pass the risk/bebefit ratio test. I think it is also wise to drive a car with airbags. I think it unwise to drive a car with airbags any riskier because of the airbags. Would you think someone with 10 jumps doing a 300-way is wise because they are jumping with an AAD? Again, doing something BECAUSE you have an airbag is different than just jumping an AAD as a back up. Derek

Kallend won't do a 10-way speed dive w/o an AAD because of the risk of collision. Let's say that collision results in an injury, say a broken neck (I hope that never happens to anyone, including Kallend, just an example). An AAD may save his life, but he wills till have a broken neck. The AAD has not prevented the collision and broken neck. How does an AAD make him any safer from a collision that can result in an injury that would render you unable to deploy either parachute? It doesn't. Therefore, if the jump has too high of a chance for a collision (fails the risk/benefit test), and an AAD doesn't change that, why make the jump because you have an AAD? Is surviving all that matters? How come I can;t find anyone that will drive two identical cars, one with airbags and one without any differently, but I can find people that will make a riskier jump because they have an AAD? What is the difference? Derek

When something unforseen happens and you use a back up device, that is what it is for. Good. People keep trying to twists things and keep bringing up the same arguments again and again. I have to keep explaining the same concept again and again. It REALLY is as simple as you put it above. Some people aren't getting it though. I agree and have never said any different. If someone says that a 100-way has more risk than benefit for them,but goes on a 100-way because they have an AAD, doesn't that defeat the concept of a back-up device? Derek

No, I'm not. If I was I wouldn't have given a crap about my main. I maintained and packed my main so that it would open. If it didn't, then I had a reserve as a back up. The main I jumped and how I packed it was below my risk/benefit ratio. I didn't do anything more dangerious because I had a reserve. No, I chose the main I jumped because it was below my risk/benefit ratio, not because I had a reserve. Derek

I was really hoping it would. How is hoping a reserve will work after you cutaway being device dependant? I wasn't intgending to use it on the jump. I treated it like a back up on those 14 jumps, just like the other 3319 jumps,b ut on those 14, I needed a back up, my reserve. I couldn't forsee that I was going to need my reserve on those jumps and that is what a back up is for, unforseen circumstance where the primary fails. Thi is about not treating AAD's like a back up device, using it to reduce risk below you risk/benefit ratio so you can make a dive that otherwise would exceed your risk/benefit ratio. Derek

I'm not. I'm recommending not do to something that exceeds his risk/benefit ratio just because he has an AAD. That is safer than doing 10-way speed stars with an AAD. No, he said it was too dangerous for him, so he depends on an AAD to lower the risk. If it the chance of a collision and injury is too high without an AAD, then it is too high with an AAD. An AAD does not reduce the chances that you'll have a collision. an AA does not reduce the chance that a collision will result in an injury. The only thing it changes is to reduce the chances that a collision that renders you unable to deploy a parachute will kill you. I don't know anything about his risk tolerance than he told me, "Once upon a time I did a bunch of 10-way speed jumps without a CYPRES, using a borrowed rig (since mine was not available). I have since decided that was pretty stupid, given the nature of 10-way speed, and now I won't do it without a CYPRES." He is depending on the AAD to reduce his risk on 10-ways. Let me say that again, he is DEPENDING on an AAD to reduce his risk. If you are depending on a device, it cannot be a back up device. Derek

Yep, I know. What does that have to do with you depending on a back up device? Yep, 14 of'em. Not one was because I skipped maintnence "Because that's what a reserve is for.", or packed poorly "Because that's what a reserve is for." or had a reserve ride because I didn't treat it like a back up only. I never depended on it. What does that have to do with you depending on a back up device? No. And I wouldn't drive over something that I thought could puncture my tire just because I have a spare. What does that have to do with you depending on a back up device? Your argument has gone from saying you are not device dependent on your AAD, to everyone depends on devices, not just you. Again, I never depended on a back up device, since that defeats the purpose of a back up device. You should reconsider how you think about AAD's and doing skydives where you are depending on it to reduce the risk to an acceptable level. Derek

I don't depend on back up devices because then they wouldn't be a back up. That is the difference. Derek

Yes. You are doing something that you feel has more risk than benefit (rsik benefit ratio) because you have an AAD. You are depending on that AAD to reduce the risk of the 1-way speed dives to lower the risk/benefit ratio back below your limit. By depending on the AAD you are, by definition, device dependant. If the AAD was, unbeknownst to you, non-functional, you would be doing a jump that is beyond your risk/benefit ratio. You are depending on it to function. Derek

What happends to things like "contact the manufacturer." or an AD/SB needs to be issued for a rig/canopy, but the manufacturer is out of business? What is happening with Eclipse tandem rating renewals since the manufacturer is out of business? What if RWS went out of business completely. Would there be no more more RWS TI's after a year? Derek

No, if they say "I can do this jump because I have a Cypres." they are still device dependant. It really is simple. If you make a jump BECAUSE you have an AAD, then you are relying on it. You shouldn't rely on AAD's. Derek

Who disagrees with this and why? If you disagree, how is this NOT depending on the AAD? Derek
