    Keep in mind that the most important job the AAD can do is not fire when it's not supposed to. (True of 3-ring releases too.) In the bad old days, there were plenty of AAD's - KAPs*, Sentinels, FXC's - that were dead simple. They were mostly mechanical and relied on changing air pressure working directly on a bellows. They misfired all the time - but with round reserves it wasn't as big a deal, and you got to know how to turn them off under canopy to avoid problems. When it came time to fire, they were pretty reliable in that they fired when they were supposed to. The big advantage modern AAD's have is they almost never fire when they are NOT supposed to, even when you do pretty stupid things to them (like put them in a trunk and slam it, or pressurize the airplane that you are in, or forget to turn them off.) (* - the KAP fired on every jump, so they really didn't have any "misfires" as we define them today.)
