Fly'n Dive

[CanadianBrett]

Alright, I'm hoping that there is someone out here that can help me. I'm a commercial pilot, and I've been diving forever. My question is... I fly in and out of great dive spots day in and day out... I know the medical factors of diving and flying, but my real question is... Do you know the exact altitude that will start causing problems for DCS.. Also... does anyone know the maximum altitude to take a full AL80 to without an explosion?

I know it's kinda a random question...

I doubt you can get high enough to blow an 80. Your plane has O2 on board right? It doesn't explode on a regular basis does it? As for an "exact altitude", you aren't going to get anything close to an exact answer. It is possible to dive within NDLs and still get bent. It is possible to dive beyond NDLs and skip deco and not get bent. How could anyone possibly nail it down to something like "752.5 feet" is safe and anything beyond is certain DCS?

Given an AL-80 will be typically filled to about 200 atmospheres pressure (well, 200 bar but its basically the same). Going from sea level to a complete vacuum would be a decrease of 1 atmosphere pressure on the outside. Thus the difference between internal and external pressure changes from 200atm at sea level to 201atm if you were to take a tank into space. So fly as high as you like, you won't pop your tank.
