When this time has elapsed, the residual nitrogen is no longer a factor for subse-

quent dives.
In the permanent Error Mode the no-flying time is 48 hours.
Flying or traveling to a higher altitude after a dive may significantly increase the risk

of decompression sickness.

WARNING!

YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER DIS-

PLAYS THE DO NOT FLY WARNING, INDICATED BY AN AIRPLANE!

Further, the Divers Alert Network (DAN) advises as follows:
A minimum surface interval of 12 hours would be required in order to be rea-

sonably 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 sickness 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 de-

layed for at least 24 hours, and if possible, for 48 hours.
