AAD Misfires?	Can't Post

I apologize if this is deemed to be in the wrong forum, I know its gear related but it IS more of a safety question IMHO...

Anyways, my question is concerning AAD misfires. As I understand it, because of the pressure variance and turbulence that occurs in the door of the aircraft, its possible to fool an AAD into firing off while you are spotting.... is this a common thing, or more of an urban legend?
I don't see much in the way of proof that this is a real problem on the fatalities database, nor do I hear much about it...
Are there particular brands of AAD to watch out for? Particular settings to be careful of?

I have never seen a modern AAD do this, although a few modern AAD's have fired near the door due to proximity to radio transmitters. (Since been fixed.)

Traditionally, mechanical AAD's (like the old FXC or Sentinel) are more sensitive to such misfirings.

Bill only not hasn't seen it, I don't think he's heard of it. Wink

This is the last thing I worry about with my AAD. Actually I've never even considered it worthy of thought. Doesn't happen.

And actually the only thing I worry about with my AAD is whether I turned it on. And that's not much of a worry with 1600 jumps or more without one.
