QuoteQuoteQuoteThe added complexity associated with any number of methods of attempting to verify with varying degrees of certainty that a closing loop was present and properly routed would not yield a safer skydiving rig.
Wrong - properly designed it would yield a safer rig, albeit a more expensive one that may falsely identify a problem thus grounding a perfectly good rig.
"Properly designed" is a circularly defined term in this argument. Wanting to add consequence-free features does not make it so.QuoteI imagine they could produce a product that would notice the lack of a closing loop routed correctly through the cutter. The additional cost to add something that senses the presence of a closing loop does not seem a sound decision based on the highly unlikely possibility it wouldn't be routed correctly and in the history of AAD's it appears to have happened only one time where it could conceivable have saved a skydiver and didn't because of human error. Airtec has made a fine product that if used correctly saves lifes. Nothing on this planet can be made idiot proof.
What I have a feeling you are picturing is a cutter that detects that something is routed through it. There's no reasonable way for an AAD to tell that that something is a properly routed closing loop. And setting aside monetary costs of doing this incomplete check you have the safety cost of a bulkier cutter that interferes more with the packjob/closing of the container, has more potential hang ups, and has a more complicated wiring harness.
You're saying the dollar cost and perhaps hassle is too high. I'm saying an event involving this added feature causing a problem with the safe operation of the rig is more likely than an event involving a rigger misrouting a closing loop and this added feature correctly detecting it.
But now you are just talking sense. The internet is no place for that!

It might be possible to design the cutter/loop so that the unit could be supplied with the part of the loop to be cut already installed.
If the cutter unit had the part of the loop to be cut as an integral part of the cutter unit . ie the loop section to be cut is always in the cutter , it wouldn't have to be placed there by the rigger .
The loop sections outside the cutter could still be easily replaceable and open to rigging errors, but the bit to be cut would remain inside .
Because a loop would have to be attached both sides of the cutter the loop would become a chain ,
A missing link in this chain may be easier to pick up than a misrouted loop.
Hope we get better AAD's out of cases like this.
Done.
You're not as good as you think you are. Seriously.

Sooo..... what happens when you just pull your reserve handle?

Well, something happens, but PLEASE stop saying that pulling the handle OPENS the reserve!
ADD - Automatic Deployment Device
AOD - Automatic Opening Device
Jumper dies on a no-pull. Family sues because the ADD/AOD did not "deploy" or "open" a parachute.
Oh, wait! We can't call it an ADD because it doesn't actually deploy or open anything. It only activates the deployment process so let's call it an AAD - Automatic Activation Device.
Oh, wait! Let's now call it a DTMOMNCACLDOITCLIRTTCP.
- Device That May Or May Not Cut A Closing Loop Depending On If The Closing Loop Is Routed Through The Cutter Properly.

QuoteThe question is: who is ultimately liable for the rigging of the device? Is the rigger solely responsible, or is the manufacturer taking an unjustified risk depending on riggers alone to install each and every unit correctly everytime?
What? Are you out of your mind? Are you so blinded by the color of money that all common sense and reason has departed you?
Oh, wait. I got indigestion this morning. I think I'll sue the toaster manufacturer because they didn't put an anti-indigestion sensor on it.
God help ALL the screwball money grabbers, including the lawyers, should I ever become king.

How exactly would you install a closing loop into a container if it's already installed in the cutter? It's not as easy of a concept as you might think.

Stay at home.
You'll be safer there.

I agree and it proves your point that as you make a system more complicated it becomes more error prone. Current AAD's are passive - they don't add any more connection points between the closing pin and the container. I would think they should remain that way. An additional sensor that detects some object is passing under the cutter is better than nothing, but not much.

Put the cutter on the outside of the rig under the reserve cover on top of the top flap?
As long as we are going to condone putting it under a top flap and the problem that creates, hell, just put it outside the top flap under the pin cover so you can see it.
