TABLE 3.3. WARNING SYMBOLS
3.6.3. Flying After Diving
The no-flying time is shown in the center window next to the airplane
image. Flying or travelling to a higher altitude should be avoided at any
time the computer counts down the no-flying time.
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 flying.
The no-flying time is always at least 12 hours or equivalent to the so-
called desaturation time (if longer than 12 hours).
In the permanent Error mode and Gauge mode the no-flying time is 48
hours.
Divers Alert Network (DAN) recommends the following 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 exceptions to this
recommendation are:
