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:
