In the previous chapter we learned that one of the safety rules when using dive tables is: avoid flying after diving for at least 12 hours and avoid flying for at least 24 hours after an unusual dive. Since diving computers are "smart tables", all the safety rules for using tables also apply to diving computers. Therefore, at the end of each dive, a no-fly symbol will appear, and at the same time the computer will display a "countdown" tracking of the remaining time until the end of the flight ban for at least 12 hours, and in cases of nitrogen debt, will extend the duration of the no-fly warning until "full nitrogen clearing".
If the computer detects an unusual dive, it will extend the no-fly warning for a longer time, up to 48 hours!
