Crest Audio CR5058 User Manual page 61

● 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 a flight. Further, the Undersea and
Hyperbaric Medical Society (UHMS) suggests divers using standard air cylinders
and exhibiting no symptoms of decompression sickness wait 24 hours after their
last dive to fly in an aircraft with cabin pressure up to 2,400 m (8,000 ft).
The only two exceptions to this recommendation are:
○ If a diver has less than two (2) hours total accumulated dive time in the last 48
hours, 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.
CREST recommends that flying is avoided until all the DAN and UHMS guidelines, as well
as the dive computer's no-fly conditions, are satisfied.
