NOTE! The airplane symbol is not shown on the
stand-by display. You should always activate the dive
computer and check that the airplane symbol is not
displayed prior to fl ying.
The no-fl ying time is always at least 12 hours or

than 12 hours).
In the permanent Error mode the no-fl ying time is
48 hours.
Divers Alert Network (DAN) recommends the fol-
lowing on no-fl ying times:
- A minimum surface interval of 12 hours would
be required in order to be reasonably assured a
diver will remain symptom free upon ascent to
altitude in a commercial jetliner (altitude up to
2400 m [8000 ft]).
- Divers who plan to make daily, multiple dives
for several days, or make dives that require de-
compression stops, should take special precau-
tions and wait for an extended interval beyond
12 hours before fl ight. Further, the Undersea
and Hyperbaric Medical Society (UHMS)
suggests divers using standard air cylinders
and exhibiting no symptoms of decompression
illness wait 24 hours after their last dive to fl y
in an aircraft with cabin pressure up to 2400
m [8000 ft]. The only two exceptions to this
recommendation are:
- If a diver had less than 2 hours total accumulat-
ed dive time in the last 48 hours, then a 12 hour
surface interval before fl ying is recommended.
- Following any dive that required a decompres-
sion stop, fl ying should be delayed for at least
24 hours, and if possible, for 48 hours.
- Suunto recommends that fl ying is avoided until
all the DAN and UHMS guidelines and the
dive computer wait to fl y conditions are satis-
fi ed.
