Flying After Diving - Suunto D3 Instruction Manual

3.3.7. FLYING AFTER DIVING

The Suunto D3 provides no calculations for no-fly times. However, 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 tanks 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:
• If a diver had less than 2 hours total accumulated dive time in the
last 48 hours, then a 12 hour surface interval before flying is
recommended.
• Following any dive that required a decompression stop, flying should
be delayed for at least 24 hours, and if possible, for 48 hours.
• Suunto recommends that flying is avoided until the DAN and UHMS
guidelines are met.
