equivalent to the so-called desaturation time (if long-
er than 12 hours).
In the permanent Error mode the no-flying time is
48 hours.
Divers Alert Network (DAN) recommends the fol-
lowing on no-flying 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
decompression stops, should take special
precautions and wait for an extended interval
beyond 12 hours before flight. 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 fly in an aircraft with cabin pressure
up to 2400 m [8000 ft]. The only two excep-
tions to this recommendation are:
- If a diver had less than 2 hours total accumu-
lated dive time in the last 48 hours, then a 12
hour surface interval before flying is recom-
mended.
- Following any dive that required a decompres-
sion stop, flying should be delayed for at least
24 hours, and if possible, for 48 hours.
- Suunto recommends that flying is avoided until
all the DAN and UHMS guidelines and the
dive computer wait to fly conditions are
satisfied.
