Obviously jumping there Bill would instantly change his attitude to that piece of hardware then.

I am curious what you think my attitude is towards AAD's?

I hope your answer to this question will help me explain better my point.

I think I already get your point and have tried to point out where we agree earlier, however my post you quoted was only intended to highlight the capriciousness of citing a regulation as a differentiating factor in a debate over what is fundamentally the personal risks skydivers should be prepared to accept. That's not something you did.

I think I agree with you on the principal that you shouldn't be relying on these devices or using them as a salve for your inability or fear of pulling etc. I disagree with relegating them to second class devices we should be prepared to jump without (even in a thought experiment / litmus test). I don't see an AAD as different from a reserve w.r.t. risk mitigation except that one might make a jump about 500-1000 times safer and the other makes it less than 2X safer on the average (*very* rough guestimates). I see these as simple abstract motivators that compel me to jump with an AAD, nothing else, just because shit happens. If a skydiver wouldn't be prepared to jump without one that might simply be prudent and it's not for anyone to tell them they therefore shouldn't be jumping at all.

I do agree that if a skydiver has issues with pulling or deliberately goes low & takes more risk because he thinks an AAD will save him he shouldn't be jumping (they're taking a huge risk and probably don't even appreciate it if you see my earlier post on probability). I don't see that as directly related to a simple choice based on historical data that an AAD makes a jump much safer, shit can happen and it's a jumper's choice and nobody else's if they would or wouldn't jump without one. I still haven't stated whether I personally would consider jumping without one.
