Diving with nitrox then flying

That's why I said "if needed". Necessity drives the mission and its parameters. They also have the option for a low altitude flight if needed and can do whatever is needed to ensure success both for the objectives and the operators. I'm well aware it is more than if they dive they can fly, but sure, ok.

Yah, that’s pretty much it. military dive programs still stick with the 12, 18, 24hr times as their base though, even for operations. the ascension tables are what you’d go to if the mission *absolutely* required a break from that. that table represents minimum acceptable risk however, it is increased risk from the baseline, so the first steps would be to change other mission variables first before accepting more risk to the divers. It’s just kinda how COs are.
