6.5.4. FLYING AFTER DIVING
The no-fl ying 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-fl ying time.
The no-fl ying time is always at least 12 hours or equivalent to the so-called desatura-
tion time (if longer than 12 hours). For desaturation times lower than 1h 10min no no-
fl y time is given.
In the permanent Error mode and Gauge mode the no-fl ying time is 48 hours.
Divers Alert Network (DAN) recommends the following 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 decompression stops, should take special precautions 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 accumulated dive time in the last 48
hours, then a 12 hour surface interval before fl ying is recommended.
