You are correct. I must have recalled incorrectly. It must have been 0.16 not 0.10. But we can still use N2 half tumes od the leading compartment to calculate no fly obligations.I have used mine in flight, I got PPO2 of 0.16 and 0.17
0.10 is too low for consciousness, hypoxia would be the result. I had clear tissues on mine, it was very interesting to see how the tissue graph loaded like crazy at first and then off gassed through the flight. Im waiting for an opportunity to take one that has been dived hard that day up and see what happens.
Assuming that the slowest compartment is the leading compartment and is fully supersaturated after the last dive, the N2 half time of the slowest compartment may be used to determine the no fly before flying to 0.5ATA.
Yes. If we can trust Buhlmann to bring us safely up from 5ATA to 1ATA, surely we can use it to bring us safety to the cabin pressure inducated by PPO2 of 1.6 for 21%. The math suggests quite short no fly times. Alternatively, if you dive something like xx/50, you would not exceed m-value in a pressurised cabin even if you fly immediately after diving. But there is no harm keeping a no fly of 24 hrs.The slowest Buhlmann compartment has a 635 minute half-life. It's hard to imagine it being fully loaded on anything other than a saturation dive.

I fully get where you are coming from and am in agreement with you. There are divers who are getting bent despite staying within NLD. The theoretical framework is far from perfect. Having said this, it does provide a useful frame of reference. For example, we can work out what if scenarios, just as we can plan for lost gas. What if war, disease or natural disaster dictates immediate air evacuation? I dive 40/70 and the ATA that corresponds to a PPO2 of 0.16 for 21% is 0.76. This suggests that I could get on a plane immediately without exceeding m-value. I’m not suggesting that anyone does this, but the theoretical framework does let us have a view about no fly.I always give myself a minimum of 24 hours which should be more than adequate in your case. However if I'm on an extended trip doing a week or more of intense diving, I usually give myself at least 2-3 days at the end of the trip before flying (so I can enjoy the local culture as well).
