Surface and no-fly time
After a dive, Suunto Nautic S displays surface time since the previous dive and a countdown time for recommended no-fly time in the watch face and in the dive stats widgets. You will see a red airplane icon and a red arch on the watch face as long as the no-fly time is present.
No-fly time is the minimum surface time after a dive which is recommended to wait before entering and flying with an airplane. It is always at least 12 hours and equals desaturation time when it is more than 12 hours. For desaturation times shorter than 75 minutes, no-fly time is not displayed.
If an algorithm deviation has occurred during the dive, the no-fly time is always 48 hours.
YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIVATE THE COMPUTER TO CHECK THE REMAINING NO-FLY TIME PRIOR TO FLYING! Flying or traveling to a higher altitude within the no-fly time can greatly increase the risk of DCS. Review the recommendations given by Divers Alert Network (DAN). There can never be a flying-after-diving rule that is guaranteed to completely prevent decompression sickness!
