5.3 No fly time The waiting period until the next flight is indicated as follows: <DO NOT FLY>;
beside, time in hours.
In some cases the no fly time is longer than with other models (reason: see des-
aturation time).
The no fly time must be strictly observed because of the
danger of the formation of gas bubbles.
5.4 Warning of bubbles Through repetitive dives microbubbles accumulate in the lungs if the surface
interval is not long enough. Ignoring decompression or an excessive ascent rate
can also lead to bubbles in tissues. In certain circumstances, in order to reduce
the risk through further repetitive dives, an extended surface interval should
be planned. The prognosis on the formation of bubbles during the surface
interval allows Aladin
®
Air Z to advise the diver to extend the surface interval.
If the display <Atn> (=attention) is visible instead of the depth during the
surface interval (surface-mode), the diver should not undertake another dive.
The extension of the interval prevents a high concentration of bubbles in the
lungs during the planned dive and avoids a risk situation.
– If the dive has to be made during <Atn> time, the <Atn> time of the following
dive can increase considerably.
– If the dive is made in spite of the display <Atn>, the diver must cope with a
clearly shorter no-stop time and an extension of decompression.
