awap:
awap - I hope you are just being disingenious because - come on - that is not how you use a computer to define no-fly time.
you know what time your flight is. say 1pm. allow 1 hour safety margin in the miraculous hope they take off early. ok.
so your flight time is 12 noon.
that means that the 24 hour margin is 12 noon the day before.
now the day before:
I wake up at 6am, switch on computer (same one that I have been diving with the last three days). see it say No-Fly=12 hours.
I do a 7am dive, after the dive at 8am, No-Fly=15 hours.
Ok - so there's a 10am dive and a 3pm dive.
Based on previous experience (by closely monitoring my no-fly times over the last few days) I elect to do the 10am dive.
On surfacing I have now racked up No-Fly=18 hours.
18 hours at 11am the day before - no worries.
But, now, my previous experience shows that if I did the 3pm dive and surfaced at 4pm that I would have more than 18 hours No-Fly time. Perhaps it is 21 hours? Perhaps. I dont really know. But even if it was 21 hours - would it be safe? Or does the rule of thumb 18 hours (as suggested previously) apply - in which case I would be fine.
Personally, I would call and not do the 3pm dive. Ok, so I "lose" one dive on my log book and that I have "paid" for. But I would rather that than (a) not go on the flight or (b) go on the flight before fully desaturating.
So, for the afternoon of the day before, I would wash up the gear, pack up my bags, and go sit in the sun with a nice cool lemonade/beer.
