7.4. Flying after diving
The no-fly time is shown in the center window next to the airplane image. Flying or traveling
to a higher altitude should be avoided at any time when the computer is counting down
the no-fly time.
The no-fly time is always at least 12 hours, or equivalent to the so-called desaturation time
(if longer than 12 hours). For desaturation times lower than 70 minutes, no no-fly time is
given.
In the Permanent Error mode and GAUGE mode the no-fly time is 48 hours.
The Divers Alert Network (DAN) recommends the following on no-fly 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 2,400 m/8,000 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 a flight. 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 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 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
• Suunto recommends that flying is avoided until all the DAN and UHMS guidelines, as
well as the dive computer’s no-fly conditions, are satisfied
7.5. PLAN mode
The PLAN mode includes a dive planner (PLANnodec) and simulation mode
(PLANsimulator).
7.5.1. Dive Planning mode (PLANnodec)
The Dive Planning mode displays no-decompression times for a new dive, taking into
account the effects of previous dives.
When entering the PLANnodec mode, the display first briefly shows the remaining
desaturation time before going into plan mode.
By pressing the UP/DOWN buttons, you can scroll the no-decompression limits in 3 m/10
ft increments ending at 45 m/150 ft. No-decompression limits longer than 99min are
displayed as “—“.
