5 minutes after a dive Aladin 2G shows
the time of day, the "do not fly time", the
no-dive warning (if applicable), the current
altitude range and the prohibited altitude
range (->31).
No-fly time is the time in hours that should
pass before a flight and is displayed and
adjusted until the value becomes 0 hours.
WARNING
Flying while Aladin 2G displays "do not fly"
may lead to serious injury or death from
decompression sickness.
WARNING
If the "no-dive" warning is visible during
the surface interval, the diver should not
undertake another dive.

Desaturation time is determined either by
oxygen toxicity, nitrogen saturation or the
regression of microbubbles, depending on
which requires the longer time.
If Aladin 2G detects a situation of increased
risk (due to the potential of microbubble
accumulation from previous dives or a
CNS O
symbol will appear on the display. The
duration of the no-dive warning is visible
in the dive planner menu. Aladin 2G
recommends this as minimum surface
interval in order to reduce the number of
microbubbles and/or to reduce the CNS O
