Hello, I was watching the Mbars change on my Teric on the plane on the way home from my last dive vacation, and have a question...
The pressure change, according to my Teric when I am flying goes from ~1K Mbars, to about 800... That change takes a while to happen on the plane, as pressure slowly drops after take off, but I am told I should wait 24 hours after diving to endure that slow 200 Mbar drop...
Yet, when I dive, and am at 33 ft, I am at ~2000 Mbar. If it takes me 8 mins to get to the top, with a 5 min safety stop, that is seen as a very safe ascent.
So my question is, is there something about that 200 Mbar change on a plane that is more problematic than the 1000 Mbar change diving? or is the flight recommendation just very conservative, or am I being dumb and my reasoning is off....
Just something I was thinking about... thanks for any insight..
