I have been boycotting the board for a number of reasons but I think that this flying and diving thread needs some clarification.
First some history: since the dawn of time the training agencies have used 12 hrs. as the bench mark for flying and diving( you needed to wait 12 hours after you dive, before you go up in the atmosphere). In 1989 Naui charge their standards, and went to 24 hours after deco dives or repetitive dives and 12 hours for a single non-deco dive (and that is still the standard today). The reason that they lengthen the time was that they were having divers bent on airplanes even after a 12 hour wait (especially after a week long dive vacation). These standards were sit-up for divers diving on AIR (29.9% O2-78% N2) not for divers diving on Tri-Mix. If you are diving on AIR, I think that you still need to follow these standards ( there are many divers who are crippled today because they went up in the atmosphere without waiting).
