No fly time?

[SCgreg]

OK guys. I'm trying to do some research for figuring out what kind of diving I can do with a flight the next day (if any at all).

My nitrox book is at the office and curiosity is killing me right now. I have a flight at 9:22am on 12/24. There is a dive trip planned for 12/23. I can't remember the rules off the top of my head.

A dive to 100' at 7:30am and another at 8:45am. Is 24 hours enough for a typical person to filter out the nitrogen?

Thanks in advance.

Differnt certf. agencies//dive computers state diff. no fly times,,,,and these are subject to change as further studies are completed,,,,,but most 'divers' will adhear to a strict No Fly time of 24 hours,,,air or EAN. For me it is a min. of 24 hours!

i try to give my self 24hrs. surface time after days of multi level diving, before i fly. hope this helps. geo

I have a multi day multi dives per day trip coming up and I planned on 24 hours before flying.

The 24 hour rule is easy, free of conditional (if/then) scenarios, and conservative. But some suggest its too conservative. Many agencies are suggesting that No-Fly times should take into account repetitive dives, multi-days, etc, with 18 hours or less as acceptable under different circumstances. Frankly, I'm not crazy about trying to beat the odds when the result can leave me incontinent, brain damaged, or paralyzed. A No-Fly time of 24 hours might be more conservative than necessary, but following a time tested rule isn't bad. I practice and teach the 24 hour rule.

Wanting to dive can be a powerful urge, but ask yourself... Would you rather chance the above scenario or live to dive unharmed fore years to come.

I agree. We have a trip coming up in June where we are spending 2 full weeks of repetitive diving, including a liveaboard. We get back into port on Thursday and we don't fly out until noon on Sunday! It will be hard to just hang out in South Beach for 2 days but it's the lengths we're willing to go to play it safe

24 hours seemed reasonable but we decided to just stay and relax and extra day before we spend 13 hours flying home.

Usually I'll wait 18-24 hours. Last trip it was 21 hours.

18-24 hours is what I have been taught. Practically, I try to wait 24 hours for a long flight. For a short flight (a couple of hours), I can accept 18 hours.
One thing though, you mention one dive at 100' at 7.30 and another dive at 8.45 AM. Are they consecutive dives? If so, it makes short surface interval, for significant depth for the first dive. With such a schedule, I would rather wait 24 hours.
Bottom line is risk management, keeping in mind that risk might be low, but consequences can be terrible.
Always tough to decide when to stop.....

Thanks guys. I don't want to push it at all. That's why I'm hoping to hack out a plan today and see just what I can safely do.

Nuts, I was just throwing the depth and times out as an example. If I do go all the way down to 100' I usually only get 15-20 minutes bottom time anyway. That would put me back on top around 7:50am. Another dive to 90' at 8.45 would give me about 55 minute surface interval. Like I said, I was just throwing out a ballpark idea of the dives I might make.
