The no-ying time is always at least 12 hours or equivalent to the so-called desatura-
tion time (if longer than 12 hours).
In the permanent Error mode the no-ying time is 48 hours.
Divers Alert Network (DAN) recommends the following on no-ying times:
A minimum surface interval of 12 hours would be required in order to be reason-
ably assured a diver will remain symptom free upon ascent to altitude in a com-
mercial 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 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 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 ying is recommended.
Following any dive that required a decompression stop, ying should be delayed
for at least 24 hours, and if possible, for 48 hours.
Suunto recommends that ying is avoided until all the DAN and UHMS guidelines
and the dive computer wait to y conditions are satised.
