Repetitive Dive Planning; Flying After Diving - Suunto D6 User Manual

7.1.3. Repetitive dive planning

The Suunto D6 includes a dive planner that allows you to review the no-decompression
limits on a subsequent dive, taking the residual nitrogen loading of previous dives into
consideration. The Dive Planning mode is explained in Section Dive Planning mode
(MEMplan) in Section 7.1.5. MEMORY mode .

7.1.4. 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:
